Abstract
BACKGROUND The COVID-19 pandemic brought about a new normal, necessitating the use of personal protective equipment (PPE) like face shields, surgical masks, gloves, and goggles. However, prolonged mask-wearing introduced skin-related issues due to changes in the skin's microenvironment, including increased humidity and temperature, as well as pressure on the skin. These factors led to skin deformation, vascular issues, edema, and inflammation, resulting in discomfort and cosmetic concerns. Clinical reports quickly highlighted the consequences of long-term mask use, including increased cases of "maskne" (mask-related acne) or mask-wearing related disorders such as rosacea flare-ups, skin-barrier defects, itching, erythema, redness, hyperpigmentation, and lichenification. Some of these issues, like inflammation, oxidative stress, and poor wound healing, could be directly linked to acne-related disorders or skin hypoxia. AIM To address these problems, researchers turned to rutin, a well-known flavonoid with antioxidant, vasoactive, and anti-inflammatory properties. However, rutin's poor water solubility presented a challenge for cosmetic formulations. To overcome this limitation, a highly water-soluble form of rutin was developed, making it suitable for use at higher concentrations. METHODS In vitro and ex vivo tests were conducted, as well as an innovative clinical trial including volunteers wearing surgical masks for at least 2 h, to evaluate the biological activity of this soluble rutin on the main skin concerns associated with mask-wearing (inflammation, oxidative stress, skin repair, hyperpigmentation, and skin redness). RESULTS The in vitro results showed that the active ingredient significantly reduced oxidative stress, improved wound healing, and reduced inflammation. In dark skin explants, the active ingredient significantly reduced melanin content, indicating its lightening activity. This effect was confirmed in the clinical study, where brown spots decreased significantly after 4 days of application. Moreover, measurements on volunteers demonstrated a decrease in skin redness and vascularization after the active ingredient application, indicating inflammation and erythema reduction. Volunteers reported improved skin comfort. CONCLUSION In summary, the COVID-19 pandemic led to various skin issues associated with mask-wearing. A highly soluble form of rutin was developed, which effectively addressed these concerns by reducing inflammation, oxidative stress, and hyperpigmentation while promoting wound healing. This soluble rutin offers a promising solution for the rapid treatment of maskne-related disorders and other skin problems caused by prolonged mask use.

Abstract
BACKGROUND Osteoarthritis (OA) is degenerative joint disorder mainly characterized by long-term pain with limited activity of joints, the disease has no effective preventative therapy. Rutin (RUT) is a flavonoid compound, present naturally. The flavonoid shows range of biological activities such as anti-inflammatory and anti-cancer effect. We screened RUT for its activity against osteoarthritis with in vivo and in vitro models of osteoarthritis. METHODS Animal model of OA was developed using C57BL/6 mice by surgical destabilization of medial meniscus. For in vitro studies the human articular cartilage tissues were used which were collected from osteoarthritis patients and were processed to isolate chondrocytes. The chondrocytes were submitted to advanced glycation end products (AGEs) for inducing osteoarthritis in vitro. Cell viability was done by CCK-8 assay, ELISA analysis for MMP13, collage II, PGE2, IL-6, TNF-α, ADAMTS-5 and MMP-13. Western blot analysis was done for expression of proteins and in silico analysis was done by docking studies. RESULTS Pretreatment of RT showed no cytotoxic effect and also ameliorated the AGE mediated inflammatory reaction on human chondrocytes in vitro. Treatment of RT inhibited the levels of COX-2 and iNOS in AGE exposed chondrocytes. RT decreased the AGE mediated up-regulation of IL-6, NO, TNF-α and PGE-2 in a dose dependent manner. Pretreatment of RT decreased the extracellular matrix degradation, inhibited expression of TRAF-6 and BCL-2 the NF-κB/MAPK pathway proteins. The treatment of RT in mice prevented the calcification of cartilage tissues, loss of proteoglycans and also halted the narrowing of joint space is mice subjected to osteoarthritis. The in-silico analysis suggested potential binding affinity of RT with TRAF-6 and BCL-2. CONCLUSION In brief RT inhibited AGE-induced inflammatory reaction and also degradation of ECM via targeting the NF-κB/MAPK pathway proteins BCL-2 and TRAF-6. RT can be a potential molecule in treating OA.

Abstract
BACKGROUND Tau pathology is a hallmark of Alzheimer's disease (AD) and other tauopathies. During disease progression, abnormally phosphorylated forms of tau aggregate and accumulate into neurofibrillary tangles, leading to synapse loss, neuroinflammation, and neurodegeneration. Thus, targeting of tau pathology is expected to be a promising strategy for AD treatment. METHODS The effect of rutin on tau aggregation was detected by thioflavin T fluorescence and transmission electron microscope imaging. The effect of rutin on tau oligomer-induced cytotoxicity was assessed by MTT assay. The effect of rutin on tau oligomer-mediated the production of IL-1β and TNF-α in vitro was measured by ELISA. The uptake of extracellular tau by microglia was determined by immunocytochemistry. Six-month-old male Tau-P301S mice were treated with rutin or vehicle by oral administration daily for 30 days. The cognitive performance was determined using the Morris water maze test, Y-maze test, and novel object recognition test. The levels of pathological tau, gliosis, NF-kB activation, proinflammatory cytokines such as IL-1β and TNF-α, and synaptic proteins including synaptophysin and PSD95 in the brains of the mice were evaluated by immunolabeling, immunoblotting, or ELISA. RESULTS We showed that rutin, a natural flavonoid glycoside, inhibited tau aggregation and tau oligomer-induced cytotoxicity, lowered the production of proinflammatory cytokines, protected neuronal morphology from toxic tau oligomers, and promoted microglial uptake of extracellular tau oligomers in vitro. When applied to Tau-P301S mouse model of tauopathy, rutin reduced pathological tau levels, regulated tau hyperphosphorylation by increasing PP2A level, suppressed gliosis and neuroinflammation by downregulating NF-kB pathway, prevented microglial synapse engulfment, and rescued synapse loss in mouse brains, resulting in a significant improvement of cognition. CONCLUSION In combination with the previously reported therapeutic effects of rutin on Aβ pathology, rutin is a promising drug candidate for AD treatment based its combinatorial targeting of tau and Aβ.

Abstract
Hematopoietic syndrome contributes to mortality after exposure to high doses of low LET radiation. In this context, we have earlier demonstrated the potential of G-003 M (a combination of podophyllotoxin and rutin) in alleviating radiation-induced bone marrow suppression. Similarly, we here demonstrate that G-003 M protected mice from death (>83% protection) and increased the populations of CD 34 (Cluster of differentiation 34) as well as CD 117 (Cluster of differentiation 117) positive cell population and their colony forming capacity. This was accompanied with increase in the serum titre of granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor (GM-CSF). Interestingly, G-003 M lowered down the titre of fms-like tyrosine kinase (Flt-3) ligands. Our results furthermore demonstrates that G-003 M facilitated the nuclear translocation of β-catenin and upregulated the expression of Wnt 10b. Conditioning of animal with G-003 M activated the expression of survivin, inhibited the activation of Caspase-3 in CD 34/117+ progenitor stem cells and protected the bone marrow vascularity and splenic colonies in lethally irradiated animals, which collectively promoted hemopoietic recovery in lethally irradiated mice.

Abstract
It is unknown whether the flavonoid rutin can protect the silver catfish liver in response to exposure to a known stressor, such as the prophylactic usage of the antimicrobial agent oxytetracycline. Thus, the current study aimed to assess the effect of rutin incorporation into the silver catfish diet formulation on oxytetracycline-induced liver oxidative stress and apoptosis. Fish were split into four groups as follows: control, rutin (1.5 g kg diet-1), oxytetracycline (0.1 g kg diet-1) and rutin+oxytetracycline (1.5 g kg diet-1 and 0.1 g kg diet-1, respectively). After two weeks of feeding with the different diets (standard, rutin-, oxytetracycline and rutin+oxytetracycline-added diets), fish were euthanized to collect the liver. Although the rutin-added diet was unable to recover glutathione peroxidase activity, ascorbic acid and reduced glutathione (GSH) levels, which were depleted due to oxytetracycline consumption, it markedly diminished the oxidized glutathione (GSSG) content, thus decreasing the GSSG to GSH ratio, an important index of oxidative stress. It also increased glutathione reductase and markedly augmented glucose-6-phosphate dehydrogenase activities, which were declined after oxytetracycline ingestion. Furthermore, the rutin-added diet reestablished superoxide dismutase and catalase activities and reduced lipid peroxidation, nitric oxide and superoxide anion levels as well, all changes resulting from oxytetracycline consumption. Finally, it also prevented oxytetracycline-induced apoptosis through increasing heat shock protein 70 and markedly decreasing high mobility group box 1 and, consequently, reducing cleaved caspase-3 protein levels. Therefore, in conclusion, the incorporation of this flavonoid to the silver catfish diet protected the liver against oxytetracycline-induced liver oxidative stress and apoptosis.

Abstract
Trichlorfon is an organophosphate pesticide used extensively for controlling ectoparasites in aquaculture. Studies have found that trichlorfon caused environmental pollution and severe neurotoxic effects in several freshwater species. Feed additives such as flavonoids may reduce or prevent pesticide-induced toxicity in fish. The aim of the present study was to determine whether acute exposure to trichlorfon impairs behavior and causes oxidative damage in brains of silver catfish (Rhamdia quelen). We also sought to determine whether rutin would be capable of preventing or reducing these effects. Silver catfish were divided into four groups: groups A and C received basal feed, while groups B and D received feed containing 3 mg rutin/kg diet for 21 days. After 21 days, groups C and D were exposed for 48 h to a nominal concentration of 11 mg trichlorfon/L water. Fish exposed to trichlorfon showed significantly longer distances travelled and swimming performances than did unexposed fish. Cerebral levels of reactive oxygen species and lipid peroxidation were significantly higher in fish exposed to trichlorfon than in unexposed fish, while cerebral superoxide dismutase, catalase, glutathione peroxidase, and acetylcholinesterase (AChE) activities were significantly lower. Taken together, our findings suggest that dietary supplementation rutin completely prevented all alterations elicited by trichlorfon, except for cerebral AChE activity; the latter remained significantly lower compared to the unexposed group. In summary, rutin prevents trichlorfon-induced neurotoxicity in silver catfish.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cecropia Loefl. species (Urticaceae) are widely spread across the rainforest in tropical and subtropical regions of Central and South America. Inhabitants of different regions of Brazil employ leaves, fruits and sprouts of Cecropia hololeuca Miq. mainly as anti-inflammatory, anti-asthmatic, expectorant, fever suppressant, and against cough. AIM OF THE STUDY To evaluate the antinociceptive and anti-inflammatory activities of an aqueous leaf extract of C. hololeuca in a murine model of zymosan-induced arthritis (ZIA) and characterize compounds contributing to these effects. MATERIALS AND METHODS The crude aqueous extract of C. hololeuca (CAE) was obtained by infusion, screened for antinociceptive and anti-inflammatory activities, and fractionated (solvent partition; RP-2 and Sephadex G-25 column chromatography), yielding fractions that were chemically and pharmacologically investigated. TLC, HPLC-DAD, HPLC-DAD-ESI-MS/MS and NMR analyses were peformed. The antinociceptive activity was assessed by means of acetic acid-induced writhing, hot-plate and rota-rod tests. ZIA was used to evaluate the anti-arthritic activity of oral treatment with CAE, butanolic (BF) and aqueous fraction (AF), as well as the fractions obtained from BF (F2, F2-A and F2-B). Rutin, a flavonoid found in C. hololeuca, was also tested. Mechanical hypernociception, joint edema, local neutrophil recruitment and articular TNF-α quantification were performed to measure the severity of arthritis and identify the anti-inflammatory potential of C. hololeuca. RESULTS CAE (0.03-1 g/kg, p.o.) showed a dose-related inhibitory effect on acetic acid-induced writhing test, but did not change the pain latency in the hotplate test, nor the first fall time on the rota-rod test. In addition, CAE (1 g/kg, p.o.) inhibited by 65% the mechanical hypernociception, 46% the joint edema, 54% the neutrophil recruitment and 53% the articular TNF-α concentration levels in ZIA. BF (0.4 g/kg, p.o.), AF (0.6 g/kg), F2 (0.1 g/kg) and F2-A (0.045 g/kg), but not F2-B (0.055 g/kg), inhibited the mechanical hypernociception, joint edema and neutrophil recruitment in ZIA. Rutin (0.001-0.03 g/kg, p.o.) produced dose-related inhibitory effects in the mechanical hypernociception, joint edema and neutrophil recruitment, and at 0.03 g/kg also inhibited articular TNF-α synthesis after intra-articular zymosan injection. Isoorientin, isovitexin, rutin and isoquercitrin were identified in the most active fraction (F2-A), along with luteolin and apigenin derivatives, tentatively identified as isoorientin-2″-O-glucoside and isovitexin-2″-O-glucoside. CONCLUSION This study corroborates the popular use by oral route of aqueous preparations of C. hololeuca against joint inflammatory disorders, such as rheumatoid arthritis. Our results demonstrated for the first time that oral administration of rutin shows antinociceptive and anti-inflammatory effects in ZIA, indicating that this flavonoid is one of the immunomodulatory compounds involved in the anti-arthritic activity of C. hololeuca.

Abstract
Age-related sarcopenia is a progressive and generalized skeletal muscle disorder associated with adverse outcomes. Herein, we evaluate the effects of a combination of electrical muscle stimulation (EMS) and a whey-based nutritional supplement (with or without polyphenols and fish oil-derived omega-3 fatty acids) on muscle function and size. Free-living elderly participants with mobility limitations were included in this study. They received 2 sessions of EMS per week and were randomly assigned to ingest an isocaloric beverage and capsules for 12 weeks: (1) carbohydrate + placebo capsules (CHO, n = 12), (2) whey protein isolate + placebo capsules (WPI, n = 15) and (3) whey protein isolate + bioactives (BIO) capsules containing omega-3 fatty acids, rutin, and curcumin (WPI + BIO, n = 10). The change in knee extension strength was significantly improved by 13% in the WPI + BIO group versus CHO on top of EMS, while WPI alone did not provide a significant benefit over CHO. On top of this, there was the largest improvement in gait speed (8%). The combination of EMS and this specific nutritional intervention could be considered as a new approach for the prevention of sarcopenia but more work is needed before this approach should be recommended. This trial was registered at the Japanese University Hospital Medical Information Network (UMIN) clinical trial registry (UMIN000008382).

Abstract
The renal cell carcinoma (RCC) is the most common type of kidney cancer. Identifying novel and more effective therapies, while minimizing toxicity, continues to be fundamental in curtailing RCC. Rutin, a bioflavonoid widely found in nature, has shown promising anticancer properties, but with limited applicability due to its poor water solubility and pharmacokinetics. Thus, the potential anticancer effects of rutin toward a human renal cancer cell line (786-O), while considering its safety in Vero kidney cells, was assessed, as well as the applicability of ionic liquids (ILs) to improve drug delivery. Rutin (up to 50 µM) did not show relevant cytotoxic effects in Vero cells. However, in 786-O cells, a significant decrease in cell viability was already observed at 50 µM. Moreover, exposure to rutin caused a significant increase in the sub-G1 population of 786-O cells, reinforcing the possible anticancer activity of this biomolecule. Two choline-amino acid ILs, at non-toxic concentrations, enhanced rutin’s solubility/loading while allowing the maintenance of rutin’s anticancer effects. Globally, our findings suggest that rutin may have a beneficial impact against RCC and that its combination with ILs ensures that this poorly soluble drug is successfully incorporated into ILs–nanoparticles hybrid systems, allowing controlled drug delivery.

Abstract
As reported in the literature, benzopyrones (alpha and gamma) have important effects on the microcirculation through various mechanisms. Coumarins are an alpha-benzopyrone as derivatives of Melilotus Officinalis, while bioflavonoids are a gamma-benzopyrone and include Rutin. Alpha-benzopyrones have two fundamental pharmacological effects: they have pro-lymphokinetic action by activating contractility of lymphangions; and the activation of macrophages to provide a proteolytic effect. Gamma-benzopyrones, such as Rutin, have an important anti-exuding and membrane stabilizing effect. Bromelain is known for its anti-inflammatory effect. The present study enrolled 52 patients with primary and/or secondary lymphedema in clinical stages I or II (according to the ISL classification) with 31 cases involving the lower limbs and 21 cases involving the upper limbs. All subjects were given for six months a natural compound consisting of 100 mg of natural Melilotus, that contains 20 grams of Coumarin, 300 mg of Rutin and 100 mg of Bromelain. The following parameters were studied at zero time (T0), after three months (T1), and after six months of treatment (T2): pitting, Stemmer's sign, measurement of limb circumferences, measurement of superficial tissue thickness in the affected limbs using ultrasound, and blood tests to evaluate hepatic function (ALT, AST, GGT, total and fractional bilirubin). At the end of the treatment (T2), the following results were observed: disappearance of pitting in 72% of the cases; unchanged Stemmer's sign; average decrease in limb circumferences of 4.2 cm; and average reduction of the superficial thickness of 29%. There was no variation in the liver function parameters examined. The combination of natural compounds (Melilotus, Rutin, and Bromelain) has been shown to be a valuable aid in the clinical control of both primary and secondary lymphedema of clinical stages I and II as well as in control of inflammatory phenomena related to chronic stasis. There were no side effects and no alteration of liver function parameters found.

Abstract
Snakebites are a major Collective Health problem worldwide. In Brazil, Bothrops jararaca snake venom (BjV) evokes hemostatic disturbances, bleeding manifestations, and redox status imbalance. Specific antivenom therapy, although efficacious to revert most snakebite-induced manifestations, is incapable of treating secondary manifestations, such as oxidative/nitrosative stress. Searching for new complementary therapies that could attenuate physiological derangements triggered by envenomation, we elected to test quercetin-3-rutinoside (rutin) by its potential as both a potent antioxidant and a hemostasis modulatory compound. The activity of rutin was evaluated both on the biological activities of crude BjV in vitro, and in vivo by the ability of rutin (14.4 mg/kg b.w.) to modulate hematological, hemostatic and redox status markers altered by BjV injection (1.6 mg/kg b.w., s.c.) in mice. In vitro, rutin failed to inhibit BjV-induced platelet aggregation and biological activities of major BjV enzymes (metalloproteinases, phospholipases A2, serine proteases, and L-amino acid oxidases). On the other hand, rutin attenuated local hemorrhage, and the increase in reactive species, prevented the fall in RBC counts and fibrinogen levels, diminished tail bleeding and shortened prothrombin time (PT) evoked by envenomation. Furthermore, rutin reduced tissue factor (TF) activity and altered the protein expression of TF in liver, lungs, heart and skin. In conclusion, the disturbances in redox status and hemostatic system induced by B. jararaca envenomation were modulated by rutin, suggesting it has a great potential to be used as an ancillary therapeutic agent for snakebites.

Abstract
In order to research and enhance bioavailability of chlorogenic acid and rutin(CA-R) via the oral route, chitosan coated composite phospholipid liposomes (C-CPLs) were applied to study on preparation, permeability and pharmacokinetic of C-CA-R-CPLs. TheC-CA-R-CPLs were prepared by the method of ethanol injection. The entrapment efficiency (EE), average particle sizes, polymer disperse index (PDI), zeta potential, shape and in vitro drug release were investigated to characterize physicochemical parameters of C-CA-R-CPLs. The penetration properties from C-CA-R-CPLs were studied through Caco-2 cells model and the pharmacokinetics in Sprague-Dawley (SD) rats were evaluated by rat jugular vein intubation tube. The EE of C-CA-R-CPLs of CA and R was 91.3±2.13% and 92.6±2.44%, particle size of C-CA-R-CPLs was 176.7±2.3 nm, PDI was 0.207±0.014 and zeta potential of 12.61±1.33 mV. CA-R-CPLs and C-CA-R-CPLs were spherical or elliptical sphere and the bilayer of the CPL was observed obviously under transmission electron. The Cmax, t1/2 and AUC0-12 h values of CA and R for groups of C-CA-R-CPLs were significantly increased.In conclusion, TheC-CA-R-CPLs as a novel nano-formulation have potential to be used to enhance the oral bioavailability of poorlywater-soluble drugs after oral administration.

Abstract
Nanocrystals are composed of 100% active and possess an increased aqueous solubility and dissolution velocity when compared to larger sized materials. Nanocrystals can be used to improve the bioavailability of poorly soluble actives not only for oral, but also for topical application. In this study nanocrystals of different sizes were produced and the influence of size on dermal penetration was investigated. The influence of different excipients and vehicles on the penetration efficacy upon dermal application was also investigated. Results confirm that dermal penetration of poorly soluble actives increases with decreasing size of the nanocrystals. Unexpectedly, it was observed that many classical penetration enhancers failed to promote the penetration of actives from nanocrystals. Also hydrogels were found to be non-suitable vehicles for the formulation of nanocrystals. As most suitable vehicles for nanocrystals oleogels and creams were identified.

Abstract
Dietary supplementation with rutin may have some pharmacological qualities including anti-inflammatory effects. Kupffer cell activation resulted in increased transcription of pro- and anti-inflammatory cytokines. The main purpose of this study was to investigate the pro- and anti-inflammatory activities in juvenile freshwater tilapia, Oreochromis niloticus, in response to 0.1 or 0.3 g/kg dietary supplementation of rutin. Results showed that hepatic IgM, anti-inflammatory-cytokines, and pro-inflammatory cytokines were significantly decreased in groups treated with high doses of rutin. Hepatic IgM and anti-inflammatory cytokines (IL-10 and IFN-γ) transcripts were significantly decreased, whereas the transcripts of the pro-inflammatory cytokines, TNFα and IL-1β were significantly decreased, whereas IL-8 was significantly increased. The number of Kupffer cells in rutin-treated groups was significantly decreased, and scanning electron micrographs showed that rutin enriched the number of gut microvilli and secretion pits. With the phenomena of cell apoptosis occurred in the rutin groups, the present study demonstrated that optimum levels of rutin may be beneficial but excessive level may cause liver impairment, which may be absorbed by the gut and then transported to the liver.

Abstract
The toxicological studies on silver nanoparticles (Ag-NPs) have become a hot topic over the past few decades due to their unique properties on the nanoscale and widespread in many commercial products that launched into the market recently. This study was undertaken to shed light on Ag-NPs toxicity on neurotransmitters with special emphasis on the impact of concurrent administration of rutin with Ag-NPs in the experimental rats. The oral administration of Ag-NPs in rats induced brain oxidative stress, significant alterations in neurotransmitters and amino acids. Furthermore, transcriptional levels of glutamatergic N-methyl-d-aspartate (NMDA) receptors, monoamino oxidases (MAO-A, MAO-B) and metallothionein-III (MT-III) showed a significant elevation in Ag-NPs intoxicated rats. Moreover, histological examinations revealed astrogliosis and demyelination of neurons concomitant with neuronal degeneration and vacuolation. Strikingly, oral administration of rutin counterbalanced the toxic effects triggered by Ag-NPs. Taken together, our findings suggested that oral administration of Ag-NPs induced neurotoxicity in rats and rutin mitigates these effects.

Abstract
There is a need for innovation in plant-derived pharmaceuticals, food supplements and nutraceutical products regarding the use of more eco-sustainable solvents for their extraction. Furthermore, the poor oral bioavailability of several phytochemicals with health promoting effects stimulates the research in the field of pharmaceutical formulations. Natural Deep Eutectic Solvents (NADES) are formed by natural compounds, and can be considered as future solvents being especially useful for the preparation of nutraceuticals and food-grade extracts. In this paper various NADES were prepared using sugars, aminoacids and organic acids. Rutin (quercetin-3-O-α-l-rhamnopyranosyl-(1→6))-β-d-glucopyranose) was used as a model compound to study NADES. Moreover, the effect of various eutectic mixtures on rutin's water solubility was studied. Proline/glutamic acid (2:1) and proline/choline chloride (1:1) mixtures have a solubility comparable to ethanol. The proline/glutamic acid (2:1) eutectic containing rutin was used in a pharmacokinetic study in Balb/c mice while bioavailability was compared to oral dosing of water suspension. Plasmatic levels of rutin were measured by HPLC-MS/MS showing increased levels and longer period of rutin permanence in plasma of NADES treated animals. This paper reports the possible use of non-toxic NADES for pharmaceutical and nutraceutical preparations.

Abstract
DNA damage can be assessed by the quantitation of γH2AX foci that form at DSB sites. This study examines the generation and persistence of γH2AX foci, variability in foci size after acute and fractionated radiation exposure, and the effect of pretreatment with a safe radioprotective formulation termed G-003M on foci generation and persistence. G-003M contains a combination of podophyllotoxin and rutin hydrate, and was administered intramuscularly to rabbits 1 hr prior to Co(60) gamma irradiation. Rabbits were assigned to one of the following treatment groups: untreated, G-003M alone, irradiated (single dose 8 Gy, fractionated 2 Gy/day for 4 days or single dose 2 Gy) or G-003M preadministration followed by radiation exposure. Foci continuously persisted for a week in peripheral blood mononuclear cells of rabbits exposed to a single 8 Gy dose. However, the number of foci gradually decreased after reaching a maximum at 1 h. In rabbits exposed to fractionated radiation, foci detected 1 hr after the final exposure were significantly larger (P < 0.001) than in rabbits exposed to a single 8 Gy dose, but disappeared completely after 24 h. In both groups, foci reappeared on days 11-15 in terminally ill animals. G-003M pretreatment significantly (P < 0.05) attenuated the formation of γH2AX foci in all irradiated rabbits. This study reveals that γH2AX focus assessment could be used to confirm radiation exposure, that focus size reflects the type of radiation exposure (acute or fractionated), that the re-appearance of foci is a strong indicator of imminent death in animals, and that G-003M provides protection against radiation.

Abstract
CONTEXT Selenium (Se) and rutin (RUT) are antioxidants that protect against tissue damage. OBJECTIVE In this study, the separate and combine protective effects of RUT and Se against cadmium (Cd)-induced renal damage were evaluated in rats. MATERIALS AND METHODS Wistar rats were treated by gavage to RUT (30 mg/kg) or Se (0.15 ppm) or Cd (200 ppm) in drinking water alone or in combination (30 mg/kg RUT +0.15 ppm Se + 200 ppm Cd). Corn oil was used as vehicle (2 mL/kg). After a 5-week treatment period, rat kidneys were removed for biochemical assays and histopathological examination. Se and Cd levels were evaluated by flame atomic absorption spectrophotometry. RESULTS The malondialdehyde and glutathione levels as well as superoxide dismutase and catalase activities in the Cd-treated animals were increased compared with control values (0.056 ± 0.0003 versus 0.011 ± 0.0005 μmol/mg; 0.005 ± 0.0006 versus 0.00085 ± 0.0002 μg/mg; 1.62 ± 0.09 versus 0.48 ± 0.12 units/mg; 650 ± 25 versus 361.89 ± 31 μmol H2O2/mg, respectively). Cd treatment was also associated with decreased renal Se concentration (4.19 ± 0.92 versus 7.73 ± 0.7 μg/g dry weight), increased alkaline phosphatase (0.07 ± 0.0015 versus 0.033 ± 0.0019 unit/mg), acid phosphatase (0.029 ± 0.0021 versus 0.015 ± 0.0016 unit/mg), and lactate dehydrogenase (0.032 ± 0.004 versus 0.014 ± 0.0027 unit/mg) activities, respectively, and with evidence of severe renal damage. The combination of RUT and Se or their separate effects prevented the Cd-induced oxidative renal damage. However, their combine effects do not have stronger effects than their separate effect against Cd-induced renal damage. DISCUSSION AND CONCLUSION RUT and Se function as potent antioxidant in the protection of renal damage induced by Cd.

Abstract
We evaluated the impact of a supplemental acerola juice (unripe, ripe, and industrial) and its main pharmaceutically active components on the concentrations of minerals in the liver and kidney of mice fed with cafeteria diet. Swiss male mice were fed with a cafeteria (CAF) diet for 13 weeks. The CAF consisted of a variety of supermarket products with high energy content. Subsequently, animals received one of the following food supplements for 1 month: water, unripe acerola juice, ripe acerola juice, industrial acerola juice, vitamin C, or rutin. Mineral concentrations of the tissues were determined by particle-induced X-ray emission (PIXE). Our study suggests that the simultaneous intake of acerola juices, vitamin C, or rutin in association with a hypercaloric and hyperlipidic diet provides change in the mineral composition of organisms in the conditions of this study, which plays an important role in the antioxidant defenses of the body. This may help to reduce the metabolism of the fat tissue or even to reduce the oxidative stress.

Abstract
Arsenic affects large populations and attacks, among others, the nervous system. Waterborne or occupational exposure causes electrophysiological alterations and motor disturbances in humans, and analogous effects were found in animals. Certain phytochemicals may be protective against As-caused damages. In the present study it was investigated whether the flavonoid rutin, applied via the drinking water (2 g/L), ameliorates the effects of arsenic given by gavage (10 mg/kg b.w., in form of NaAsO2) on open field motility, evoked cortical and peripheral electrophysiological activity, and body weight gain in adult male Wistar rats. Body weight gain was significantly reduced from the 4th week of the 6 weeks arsenic treatment and this effect was largely abolished by rutin in the combination treatment group. Rats treated by arsenic alone showed decreased open field motility; latency of the cortical evoked potentials increased and peripheral nerve conduction velocity decreased. These functional alterations were also counteracted by co-administration of rutin, and both the antioxidant and the chelating activity of rutin might have contributed to the ameliorative effect. These results are apparently novel and support the potential role of natural agents in preserving human health in a contaminated environment.

Abstract
The aim of the study was to assess the effect of a combined preparation of Vitaprost on blood supply and microcirculation in the prostate gland in 35 patients with chronic infectious urethral prostatitis. The effectiveness of treatment was estimated by a combination of clinical, bacteriological and instrumental diagnostic methods. Transrectal ultrasonography with color Doppler and laser Doppler flowmetry were used to estimate all components of blood circulation in the prostate. Examination results obtained before and after treatment showed better clinical outcomes and improved parameters of blood flow and microcirculation in the prostate in patients receiving Vitapost. These results indicate that combination therapy including Vitaprost is effective in correcting blood flow and microcirculatory disorders of the prostate and can be utilized in the treatment of chronic infectious urethral prostatitis.

Abstract
Ischemic-reperfusion (I/R) is a major event in the pathogenesis of ischemic heart disease that leads to higher rate of mortality. The study has been designed to investigate the therapeutic potential and molecular mechanism of vitamin P and digoxin in I/R-induced myocardial infarction in isolated rat heart preparation by using Langendorff apparatus. The animals were treated with vitamin P (50 and 100 mg/kg; p.o.) and digoxin (500 μg/kg) for 5 consecutive days. Digoxin served as a positive control in the present study. On the sixth day, the heart was harvested and induced to 30 min of global ischemia followed by 120 min of reperfusion using Langendorff apparatus. The coronary effluent was collected at different time intervals (i.e. basal, 1, 15, 30, 45, 60 and 120 min.) for the assessment of myocardial contractility function. In addition, creatine kinase-M and B subunits (CK-MB), lactate dehydrogenase (LDH1) and Na(+)-K(+)-ATPase activity along with oxidative tissue biomarkers (i.e. thio-barbituric acid reactive substances (TBARS) and reduced glutathione (GSH)) changes were estimated. The I/R of myocardium produced decrease in coronary flow rate; increase in CK-MB, LDH1 and Na(+)-K(+)-ATPase activity along with increase in TBARS and decrease in GSH levels as compared to normal group. The treatment with vitamin P (100 mg/kg) and digoxin (500 μg/kg) have produced a significant (p < 0.05) ameliorative effect against I/R induced above functional, metabolic and tissue biomarkers changes. Vitamin P has an ameliorative potential against I/R induced myocardial functional changes. It may be due to its free radical scavenging and anti-infarct property via inhibition of Na(+)-K(+)-ATPase activity. Therefore, it can be used as a potential therapeutic medicine for the management of cardiovascular disorders.

Abstract
A new strategy was designed to evaluate the antioxidant effectiveness of five topically applied polyphenols following skin penetration profiles. The antioxidants were the following polyphenol derivatives: epicatechin, resveratrol, rutin, quercetin, and trolox, which was used as the reference antioxidant. The hydrophilic/lipophilic character of these compounds was evaluated, and their antioxidant activity was measured by the DPPH method. The percutaneous absorption of these polyphenols was obtained by an in vitro methodology using porcine skin biopsies. This methodology involves the quantification of the antioxidants present in each specific skin layer to evaluate antioxidant effectiveness. The antioxidant activity in each skin layer was also determined by the DPPH method. The results indicated that lipophilic antioxidants (epicatechin, resveratrol, quercetin, and trolox) penetrated deeper into the skin layers, whereas a more hydrophilic compound, rutin, remained on the skin surface. The antioxidant evaluation of each skin compartment suggested that resveratrol and rutin were the most effective topically applied compounds in view of their antioxidant activity and their skin penetration profile.

Abstract
OBJECTIVE To observe the protective effect of rutin (RUT) on neuronal cells against sodium nitroprusside (SNP) induced neurotoxicity. METHODS PC12 cells were treated with different concentration of SNP for 24 h and MTT assay was applied to analyze the survival rate; PC12 cells were pretreated with rutin for 1 h, and then incubated for 24 h with SNP. MTT assay, morphological observation, as well as immunofluorescence were performed to evaluate both the SNP neurotoxicity and the protective effects of RUT, Western blot was used to analyzed the level of phosphorylated extra cellular regulated protein kinases (ERK1/2) after treatment with RUT, the results were also testified in primary cultured neurons. RESULTS Results from MTT assay showed that SNP caused cell death in a concentration-dependent manner in PC12 cells. The effect of SNP was observed at 200 - 1 000 micromol/L and was significant at 800 micromol/L. 25 micromol/L rutin partly blocked the neurotoxicity of SNP by preventing PC12 cells from apoptosis. Hoechst and PI staining indicated that SNP treatment decreased the number of viable cells and induced shrinkage and aggregation of the nucleus, whereas RUT pretreatment attenuated the toxic effects of SNP, after treatment with RUT in PC12 cells, the phosphorylation of ERK1/2 was increased and peaked at 20 min. Most importantly, the protective effect of RUT on PC12 cells was confirmed on cultured neurons. CONCLUSION RUT possesses protective effect against neuronal apoptosis induced by SNP and this effect may be partially related with ERK1/2 signaling.

Abstract
Acute lung injury (ALI) is a serious disease with unacceptably high mortality and morbidity rates. Up to now, no effective therapeutic strategy for ALI has been established. Rutin, quercetin-3-rhamnosyl glucoside, expresses a wide range of biological activities and pharmacological effects, such as anti-inflammatory, antihypertensive, anticarcinogenic, vasoprotective, and cardioprotective activities. Pretreatment with rutin inhibited not only histopathological changes in lung tissues but also infiltration of polymorphonuclear granulocytes into bronchoalveolar lavage fluid in lipopolysaccharide (LPS)-induced ALI. In addition, LPS-induced inflammatory responses, including increased secretion of proinflammatory cytokines and lipid peroxidation, were inhibited by rutin in a concentration-dependent manner. Furthermore, rutin suppressed phosphorylation of NF-κB and MAPK and degradation of IκB, an NF-κB inhibitor. Decreased activities of antioxidative enzymes such as superoxide dismutase, catalase, glutathione peroxidase, and heme oxygenase-1 caused by LPS were reversed by rutin. At the same time, we found that ALI amelioration by chelation of extracellular metal ions with rutin is more efficacious than with deferoxamine. These results indicate that the protective mechanism of rutin is through inhibition of MAPK-NF-κB activation and upregulation of antioxidative enzymes.

Abstract
Nutraceutically, much of the literature has indicated that an aglycon and its related glycoside would act similarly. However, controversial reports are accumulating. We hypothesize that rutin (RT) and quercetin (QT) pharmacodynamically could act differently. To confirm this, doxorubicin (DR) (8.5 mg/kg) was used to induce rat chronic kidney disease (CKD) and then treated with QT and RT (each 70 mg/kg body weight per day) for 13 weeks. QT exhibited better body weight gaining effect (420 ± 45) vs RT, 350 ± 57 g/rat (p < 0.001). DR raised the ratio kidney-to-body weight (%) to 0.82 (p < 0.001) vs RT, 0.62 (p < 0.01), and QT, 0.35 (p < 0.01). DR reduced the glomerular filtration rate to 25.2 vs RT, 48 ± 11.3; QT, 124.7 ± 12.8 (p < 0.001) and the control, 191.5 ± 15.7 mL/h (p < 0.001). DRCKD reduced hematocrit to 29 ± 5; RT, to 28 ± 5 (p < 0.05); QT, to 36 ± 6 vs the control 37.5 ± 4%, (p < 0.01). DRCKD reduced the serum albumin (s-Ab) to 2.1 ± 0.2 (p < 0.001); QT, to 2.7 ± 0.2 (p < 0.05) vs the normal 4.3 ± 0.5 g/dL, yet RT was totally ineffective. DRCKD raised serum cholesterol level to 340 ± 30; vs RT, 260 ± 12; QT, 220 ± 25; and the normal value, 70 ± 25 mg/dL. DRCKD increased serum triglyceride to 260 ± 15 (p < 0.001), RT and QT restored it to 170 ± 25 and 200 ± 15 (p < 0.05) vs the normal 26-145 mg/dL. DRCKD elevated blood urea nitrogen to 38 ± 3 vs RT, to 98 ± 6 mg/dL (p < 0.001), implicating "protein-energy malnutrition". RT stimulated serum creatinine (sCr) production to reach 6.0 ± 0.9 mg/dL (p < 0.001). QT did not alter the sCr level. RT but not QT induced uremia and hypercreatininemia. DR significantly downregulated Bcl-2, but highly upregulated Bax, Bad, and cleaved caspase-3, implicating the intrinsic mitochondrial pathway. DR damaged DNA, but QT completely rescued such an effect and recovered renal amyloidosis and collagen deposition. Conclusively, RT and QT act differently, and RT is inferior to QT with respect to treating CKD.

Abstract
CONTEXT Rutin, a flavonoid commonly present in onions, apples and tea, has been suggested to have a variety of pharmacological activities, including immunomodulator, anti-inflammatory and antioxidant activities. OBJECTIVES The present study was to examine the protective effects of rutin on gastric mucosal damage induced by gastric ischemia-reperfusion (I/R) in rats. MATERIALS AND METHODS Rutin (50, 100, 200 mg/kg) was administered intragastrically for five consecutive days before ischemia. Sixty minutes after the last administration of rutin, under anesthesia, the celiac artery was clamped for 30 min, and then the clamp was removed for 60 min reperfusion. After reperfusion, the stomach was removed for biochemical and histological examinations. RESULTS As compared with the I/R group (116.7 ± 21.5), administration of rutin at doses of 50, 100 and 200 mg/kg significantly prevented the increase of gastric mucosal injury index induced by gastric I/R (73.4 ± 14.8, 65.9 ± 9.6 and 26.9 ± 5.7, respectively). ED50 value was 138.7 mg/kg. Moreover, rutin at doses of 50, 100 and 200 mg/kg showed an inhibition on the increased myeloperoxidase (24.6, 41.3 and 53.1% reduction) activity and malondialdehyde levels (27.4, 40.3 and 50.7% reduction) in gastric mucosa. Also, the elevation of inducible NO synthase (iNOS) activity as well as the decrease of constitutive NO synthase (cNOS) in the gastric mucosa were significantly prevented by rutin pretreatment. CONCLUSION These results suggested that rutin has a protective effect against gastric mucosal injury induced by gastric I/R and that the gastroprotection was related to the NOS/NO pathway and its antioxidant activity.

Abstract
BACKGROUND AND AIM Chronic use of multi-dose eye drops containing preservatives, such as it may happen in patients affected by primary open angle glaucoma, often results in a damage of the ocular surface due to the inherent toxicity of preservatives, that with time may lead to a lacrimal dysfunction syndrome and eye dryness. PATIENTS AND METHODS This double blind, randomized, pilot study was conducted on 38 glaucomatous patients suffering from dry eye induced by long-term use of eye drops preserved with BAK. RESULTS Treatment of these patients with a food supplement containing an association of forskolin, rutin and vitamins B1 and B2 for 30 days increased significantly their OPI values and improved the symptoms of dry eye with respect to a placebo-treated control group. CONCLUSIONS The association of forskolin, rutin and vitamins B1 and B2 appears to be protective for the ocular surface, contributing to restore a normal equilibrium of the tear film in those subjects in which toxic agents such as BAK had determined alterations of its homeostasis.

Abstract
BACKGROUND Reperfusion therapy used in the treatment of cerebral ischemia often causes reperfusion neurological injury. Multiple pathological processes are involved in this injury including oxidative stress and components of the inflammatory response appear to play key roles in these deleterious effects. Thus new therapeutic strategies aimed at neutralization of OS-induced neurotoxicity support the application of natural antioxidant bioflavonoids. Both experimental and epidemiological evidence demonstrate that bioflavonoid such as quercetin and rutin are neuroprotective in models of cerebral ischemia reperfusion injury. However, recent studies indicate that the radical scavenger property of quercetin and rutin is unlikely to be the only reason for their cerebroprotective actions and in fact, a wide spectrum of cellular signaling events may well account for their biological actions. AIM In this study we attempted to establish the various mechanisms involved in the cerebroprotective activity of quercetin and rutin. METHODS Adult Sprague Dawely rats were anesthetized with thiopentone and subjected to global cerebral ischemia by occlusion of bicommon carotid arteries. Infarct size (TTC staining), SOD, MDA, CAT and MPO levels was assessed 4 h after the onset of ischemia. RESULTS Quercetin (50 mg/kg) and rutin (10 mg/kg) administered 10 min before reperfusion resulted in significant reduction of infarct size, MDA, and MPO levels and significant increase in SOD and CAT levels. Administration of L-NAME prior to administration of quercetin and rutin, significantly reduced the cerebroprotection offered by quercetin and rutin. CONCLUSIONS Possible partial role of antioxidant, anti-inflammatory and involvement of NO in the beneficial effects of bioflavonoids quercetin and rutin against cerebral ischemia reperfusion injury was observed.

Abstract
BACKGROUND Rutin, a polyphenolic flavonoid, was investigated for its protective effects against the KBrO(3) induced renal injuries in rat. METHODS Group I was control (untreated), group II was given saline 0.5 ml/kg bw (0.9% NaCl), group III was administered KBrO(3) (20 mg/kg bw) intragastric twice a week for four weeks. Rutin was administered to group VI (50 mg/kg bw) and Group V (70 mg/kg bw) along with KBrO(3) (20 mg/kg bw) while group VI was given rutin (70 mg/kg bw) alone twice a week for four weeks. Protective effects of rutin on KBrO(3)-induced nephrotoxicity in rats were determined for biochemical parameter of urine, and serum, various antioxidant enzymes, DNA and histopathological damages in kidneys. RESULTS The level of urinary red blood cells, leucocytes count, specific gravity, urea, creatinine and urobilinogen was increased (P<0.01) whereas creatinine clearance was reduced. Serum level of protein, albumin, globulin, nitrite, creatinine and blood urea nitrogen (BUN) was significantly increased (P<0.01) by KBrO(3). Marked histopathological lesions, elevated DNA fragmentation and AgNORs count in renal tissues was determined. Activity of antioxidant enzymes; catalase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, glutathione reductase, and reduced glutathione contents were decreased (P<0.01) while thiobarbituric acid reactive substances were increased (P<0.01) with KBrO(3) treatment in kidneys. DNA ladder assay was intimately related with the DNA fragmentation assay. Telomerase activity was found positive in the KBrO(3) treated kidneys. Treatment with rutin effectively ameliorated the alterations in the studied parameters of rat. Rutin administration alone to rats did not exhibit any significant change in any of the parameters studied. CONCLUSION These results suggest that rutin works as an antioxidant in vivo by scavenging reactive oxygen species and this serves to prevent oxidative renal damage in rat treated with KBrO(3).

Abstract
CONTEXT In the Indian traditional system of medicine, Melothria heterophylla (Lour.) Cogn., (Cucurbitaceae) is prescribed for the treatment of diabetes mellitus. OBJECTIVE In the present study, the antidiabetic effect of ethanol extract of Melothria heterophylla (EEMH), and its active isolated constituents were investigated in streptozotocin (STZ)-induced diabetic Swiss albino rats. METHOD Successive Soxhlet extraction of the dried total aerial parts with petroleum ether for defatting and then with ethanol (95%) to obtain ethanol extract, which was concentrated under reduced pressure. Hyperglycemia was induced in rats by STZ (50 mg/kg, body weight). Twenty-four hours after STZ induction, respective groups of diabetic rats received EEMH (200 and 400 mg/kg, body weight), gallic acid (GA) (2 and 4 mg/kg, body weight), and rutin (RU) (2 and 4 mg/kg, body weight), respectively, orally daily for 15 days. Glibenclamide (0.5 mg/kg, orally) served as reference. Blood glucose levels and change in body weight were measured on every 5(th) day during 15 days of treatment. Biochemical parameters, viz., serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) and serum insulin, were measured. RESULTS EEMH and its active constituents significantly (p < 0.01) normalized blood glucose levels and serum biochemical parameters as compared to those of STZ controls. Both GA (4 mg/kg) and RU (4 mg/kg) exhibited maximum glucose lowering effect (69.1 and 66.7%, respectively) in diabetic rats compared to the other dose (2 mg/kg) at the end of the study. EEMH, gallic acid and RU also showed significant increase in serum insulin, and body weight of STZ-induced diabetic rats. CONCLUSION Therefore, ethanol extract of Melothria heterophylla, GA and RU demonstrated remarkable antidiabetic activity in STZ-induced diabetic rats.

Abstract
To investigate the effects of dietary β-glucan (0.5 or 1 g kg⁻¹ diet: 0.5-BG, 1-BG) and rutin (0.5 or 1 g kg⁻¹ diet: 0.5-RT, 1-RT) after 10 days in the absence of pathogen challenge on the immune response of Fenneropenaeus chinensis, we determined total hemocyte count (THC) and the expression of four immune-related genes in hemocytes: those for prophenoloxidase (proPO), peroxinectin (PX), lipopolysaccharide and/or β-glucan binding protein (LGBP), and c-type lectin (CL). As a prerequisite for subsequent experiments, cDNA encoding proPO of the fleshy shrimp, Fenneropenaeus chinensis (f-proPO) was obtained from hemocytes; it had a full length of 3023 bp, with an open reading frame (ORF) of 2061bp, a 105-bp 5'-untranslated region, and a 906-bp 3'-untranslated region containing the poly A signal. The THCs of shrimp fed β-glucan of 1 g kg⁻¹ diet, and rutin of 1 g kg⁻¹ diet were significantly higher than that of the control (P < 0.05). The expression of proPO mRNA was slightly downregulated and that of LGBP mRNA was upregulated (except in 1-RT). PX and CL mRNA remained constitutively expressed in all groups. Our results reveal that β-glucan and rutin dietary supplements have minimal effect on immune response in the absence of pathogen challenge.

Abstract
The effect of rutin (RT) on the expression of PPARγ in the skeletal muscle of db/db mice has been investigated. Thirty db/db mice were randomized into 5 equal groups: model control group (MCG), positive control group 30 mg/kg pioglitazone hydrochloride (PCG), low-dose rutin group 50 mg/kg (LRT), middle-dose rutin group 100 mg/kg (MRT), high-dose rutin group 200 mg/kg (HRT), and 6 other db/m mice were used as the normal control (NC). The expression of PPARγ mRNA and protein in the skeletal muscle was determined by real-time quantitative PCR and Western Blot, respectively. Treatment with HRT resulted in significant decreases in the plasma levels of glucose and lipids (p < 0.001). Compared to the MCG, the expression of PPARγ mRNA and protein of the skeletal muscle was significantly increased in the HRT and PCG groups (p < 0.001 and p < 0.05, respectively). Rutin can increase the expression of PPARγ in skeletal muscles of db/db mice.

Abstract
OBJECTIVE Comparison of the effects of a high-fructose diet supplemented with rutin, a phenolic compound with well-recognized bioavailability and bioactivity, and a chicory (Cichorium intybus L.) seed extract rich in caffeoylquinic acids (CQA) on gut physiology and the development of disorders related to metabolic syndrome. METHODS A 28-d experiment was conducted on 32 young male Wistar rats. In comparison with control rats fed a standard corn starch diet (group C), the experimental group (group E) was fed a diet with an increased content of cholesterol and fructose (to 1% and 66% of the diet, respectively), as well as with oxidized soybean oil. Rats from the other two experimental groups were administered the same diet as group E during the first 2 wk of feeding, whereas at the beginning of the last 2 wk, the diet was enriched with rutin (group ER) or the CQA-rich ethanol extract from chicory seeds (9.6% of CQA, group EC), so the amount of added phenolics was equal in both dietary groups (0.15%). RESULTS The diet administered in group E caused hyperglycemia and increased blood serum atherogenicity in rats, but did not induce other manifestations of the metabolic syndrome, i.e., dyslipidemia and oxidative stress. Additionally, it affected gut physiology through increasing mucosal sucrase activity and disturbing fermentative processes in the cecum, such as the production of short-chain fatty acids and the activity of microbial enzymes. Similarly to rutin, the dietary addition of the chicory seed extract improved glycemia, which was comparable to that determined in group C. In addition, the extract was found to decrease the atherogenic index to the level observed in group C and to increase blood antioxidant status. Both dietary supplements reduced the content of thiobarbituric acid-reactive substances in kidney and heart tissue when compared with group E. CONCLUSION The potential efficacy of the CQA-rich extract from chicory seeds in improving diet-induced metabolic disturbances proved to be better than that of rutin; thus, the extract might be considered as a dietary supplement for carrying out clinical trials.

Abstract
Quercetin and rutin are popular flavonoids in plant foods, herbs, and dietary supplements. Cyclosporine (CSP), an immunosuppressant with a narrow therapeutic window, is a substrate of P-glycoprotein (P-gp) and cytochrome P-450 3A4 (CYP3A4). This study investigated the effects of quercetin and rutin on CSP pharmacokinetics from Neoral and relevant mechanisms. Rats were orally administered Neoral with and without quercetin or rutin. The blood CSP concentration was assayed by a specific monoclonal fluorescence polarization immunoassay. The results showed that quercetin and rutin significantly decreased the C(max) of CSP by 67.8 and 63.2% and reduced the AUC(0-540) by 43.3 and 57.2%, respectively. The in vitro studies indicated that the quercetin and rutin induced the functions of P-gp and CYP3A4. In conclusion, quercetin and rutin decreased the bioavailability of CSP through activating P-gp and CYP3A. Transplant patients treated with Neoral should avoid concurrent consumption of quercetin or rutin to minimize the risk of allograft rejection.

Abstract
The aim of this work was to investigate the antibacterial activity of flavonoid and nonflavonoid phenolic compound combinations and the synergistic antibacterial effects against Escherichia coli ATCC 35218. In nutrient medium, the combinations of gallic and protocatechuic acids, gallic and caffeic acids, and rutin and quercetin were the best antibacterial agents, with synergistic effects, and were selected to test their activity in a meat model system. All combinations diminished the bacterial growth, without cellular death at 20 degrees C. The combinations of gallic and caffeic acids and rutin and quercetin were the most effective at 4 degrees C; no viable cells were detected with 100 or 200 mg/L at 21 or 14 days of incubations, respectively. The lowest decimal reduction times were found with the rutin-quercetin combination. These results demonstrate a synergistic effect of the selected combination of flavonoid or nonflavonoid compounds with an important antibacterial effect in meat, using low concentrations.

Abstract
Lymphedema may be presented in mild or less severe form. Nowadays, accurate diagnosis and effective therapy are available. Wearing surgical bandage, massage, exercise, and pumps form the core program for most patients with lymphedema. The application of pharmacological therapies has been notably absent from the management strategies for lymphatic vascular insufficiency states but lately some progress has been made by applying wobenzym in the treatment. Surgical approaches to improve lymphatic flow through vascular anastamosis have been, in large part, unsuccessful, but controlled liposuction affords lasting benefit in selected patients.

Abstract
Substances and macromolecules absorbed by the lymphatic system avoid hepatic first-pass effect and directly enter the blood circulation system. In this study, an anesthetized, mesenteric lymphatic/duodenum-cannulated rat model was used to investigate the role of lymphatic absorption with intraduodenally administered drugs. Quercetin and rutin were administered, respectively, at dosages of 30 and 300 mg/kg intraduodenally. Lymph and plasma samples were collected every 30 min. These samples were prepared by protein precipitation and then analyzed by high-performance liquid chromatography with a photodiode array detector (HPLC-PDA) and verified by LC tandem mass spectrometry (LC-MS/MS). Quercetin was separated by a C18 reversed-phase column, and rutin was separated by a phenyl reverse-phase column. Pharmacokinetic parameters were calculated using the software WinNonlin Standard Edition Version. The maximum concentration (Cmax) of quercetin recovered in lymph, 1.97+/-0.96 microg/mL, was about 5-fold higher than that in plasma, 0.41+/-0.08 microg/mL. The time to reach the highest concentration (Tmax) of quercetin in lymph was 30 min longer than that in plasma. The maximum concentration (Cmax) of rutin recovered in lymph, 0.86+/-0.13 microg/mL, was slightly lower than that in plasma, 1.35+/-0.37 microg/mL. The area under curve (AUC) of rutin recovered in lymph, 359+/-41 min microg/mL, was about 2-fold higher than the AUC of rutin in plasma, 150+/-22 min microg/mL. This phenomenon was due to the milder concentration decline of rutin in the lymphatic system. These results demonstrate the pharmacokinetic data of lymphatic and systemic absorption after intraduodenally administered quercetin and rutin. It is also the first report revealing the lymphatic absorption of rutin. Although both quercetin and rutin are absorbed and transported mainly via the blood circulation system, the AUC of these two drugs in lymph fluid appeared higher than their respective AUC in plasma.

Abstract
BACKGROUND/AIMS Control of intraocular pressure is still the main strategy to treat glaucoma patients. Forskolin has already shown an ability to control intraocular pressure after topic administration, whereas rutin is known to improve ocular blood fl ow. Therefore, aim of this pilot study has been to observe whether administration of an association of oral forskolin and rutin to POAG patients under different regimens of medical therapy may contribute to their effects, further decreasing IOP values. MATERIALS AND METHODS Forskolin (a natural compound present in the crude extract of the plant Coleus Forskohlii) and rutin are the main ingredients of a food supplement commercially available in Italy. In an open label pilot study, 16 patients with POAG under treatment with different topical drugs and with stable IOP were given additional treatment with the food supplement for 40 days, and their IOP values measured at enrolment, at the end of treatment and 40 days after treatment interruption. RESULTS Further addition of forskolin and rutin to topical association treatments resulted in a further decrease of IOP by roughly 20% of the initial value. The effect was reversible upon suspension of the treatment. CONCLUSIONS These data show for the fi rst time that forskolin and rutin given through the oral route appear to reach the ocular district, where they can act in synergy with topical pharmacological treatments, and contribute to the control of intraocular pressure.

PURPOSE Idarubicin is a synthetic anthracycline anticancer drug widely used in the treatment of some hematological malignancies. The studies in our laboratory have clearly demonstrated that idarubicin can undergo reductive bioactivation by NADPH-cytochrome P450 reductase to free radicals with resulting formation of DNA strand breaks, which can potentially contribute to its genotoxic effects [Celik, H., Arinç, E., Bioreduction of idarubicin and formation of ROS responsible for DNA cleavage by NADPH-cytochrome P450 reductase and its potential role in the antitumor effect. J Pharm Pharm Sci, 11(4):68-82, 2008]. In the current study, our aim was to investigate the possible protective effects of several phenolic antioxidants, quercetin, rutin, naringenin, resveratrol and trolox, against the DNA-damaging effect of idarubicin originating from its P450 reductase-catalyzed bioactivation. METHODS DNA damage was measured by detecting single-strand breaks in plasmid pBR322 DNA using a cell-free agarose gel method. RESULTS Our results indicated that, among the compounds tested, quercetin was the most potent antioxidant in preventing DNA damage. Quercetin significantly decreased the extent of DNA strand breaks in a dose-dependent manner; 100 microM of quercetin almost completely inhibited the DNA strand breakage. Unlike quercetin, its glycosidated conjugate rutin, failed to provide any significant protection against idarubicin-induced DNA strand breaks except at the highest concentration tested (2 mM). The protective effects of other antioxidants were significantly less than that of quercetin even at high concentrations. Quercetin was found to be also an effective protector against DNA damage induced by mitomycin C. CONCLUSION We conclude that quercetin, one of the most abundant flavonoids in the human diet, is highly effective in reducing the DNA damage caused by the antitumor agents, idarubicin and mitomycin C, following bioactivation by P450 reductase.

Abstract
Ninety patients with new-onset pulmonary tuberculosis were examined prior to therapy The patients were randomized into 2 groups: 1) 20 patients receiving the standard antibiotic therapy regimen; 2) 70 patients taking the standard antibiotic therapy and the polyenzyme drug Wobenzym. The use of the latter in the complex therapy of patients with pulmonary tuberculosis was shown to cause an increase in the activity of the destructive inflammatory process and to regulate the function of the immune system as compared with those during the standard therapy.

Abstract
Rutin deca (H-) sulfate sodium (RDS) possesses very good activity as an inhibitor of the complement system of warm-blooded animals and HIV. An ion-pair coupled with solid-phase extraction technique (IP-SPE) was developed to extract RDS from rat plasma, urine, bile and protein solution samples. The assay was applied to pharmacokinetics of RDS, including plasma pharmacokinetics, excretion and protein binding studies. After i.v. 5, 20 and 100 mg x kg(-1) RDS via tail vein in rats, the plasma concentration-time profiles were fitted using 3P97 software. The average terminal half-life (t(1/2)) was 3.432 +/- 0.185 2 h. The relationship of dose and AUC of RDS was linear within the dosage range. This suggested that the disposition of RDS in rats belong to linear kinetics and the pharmacokinetic parameters of RDS were dose independent. After iv RDS 20 mg x kg(-1) in rats, the biliary excretion amount of parent drug amount was only 0.3181% +/- 0.2087% of given dosage, and the urinary excretion was 86.0% +/- 6.1% in 36 h. Ultrafiltration techniques were applied to determine the protein binding of RDS in plasma (from SD rat, Beagle dog and human), human serum albumin (HSA) and human alpha1-acid glycoprotein (AGP). The mean protein binding rate in plasma of SD rat, Beagle dog and human plasma of RDS were 80%-90%, in which the range of concentration of RDS was 5 to 100 microg x mL(-1). The protein binding to HSA was 85.7% +/- 1.3% and 14.0% +/- 3.2% to AGP.

Abstract
A highly soluble quercetin glycoside, alphaG-rutin, is a glucose adduct of insoluble rutin, and intestinal absorption and metabolism of alphaG-rutin has not been known. We investigated the intestinal absorption and metabolism of alphaG-rutin by using portal and duodenal cannulated rats and the isolated rat intestinal mucosa. After a duodenal instillation of alphaG-rutin (150 mumol), intact alphaG-rutin, rutin and quercetin were appeared in the portal blood and these concentrations were similarly increased at 15 min. Portal quercetin reached a peak value at 60 min, and the value was higher than those of alphaG-rutin and rutin at that time. Quercetin-conjugates were also increased 30 min after the instillation. The remaining of alphaG-rutin metabolites, mainly rutin, in the intestine were 58% of instilled alphaG-rutin after 150 min. In the experiment by using the isolated mucosa of the jejunum, ileum and cecum, alphaG-rutin and rutin, but not quercetin, appeared in the serosal sides of all segments, and they were increased linearly from 10 to 100 mmol/l of mucosal alphaG-rutin. We also showed portal injected alphaG-rutin was very rapidly cleared from the blood, and appeared a large amount of conjugates. In conclusion, a soluble flavonoid-glycoside, alphaG-rutin, was absorbed as glycosides into the portal blood. A part of alphaG-rutin was hydrolyzed to rutin, but not to aglycone, through the intestine.

Abstract
An optimized therapeutic rehabilitation program involved 393 patients with fractured long bones (humeral, radial/ulnar, femoral, crural) admitted to the Orthopedic Department of the Stavropol Regional Children's Clinical Hospital and the Rehabilitation Centre for Handicapped Children and Adolescents. Rehabilitation was performed in three consecutive stages, viz. immobilization, functional recovery and training. The proposed approach ensured rather fast functional recovery of the affected extremity even in cases with compound fractures. The rehabilitation program included polyenzyme therapy with wobenzym during 3-4 weeks after injury or surgical repositioning of bone fragments. Pain and oedema syndromes resolved twice as fast as after traditional treatment. The use of this program permitted to avoid development of contracture and disturbances of locomotary activity; moreover, it improved the quality of life in children with fractures of long tubular bones.
