Wang Y, Zhou D, Zhang X, Qing M, Li X, Chou Y, Chen G, Li N. Curcumin promotes renewal of intestinal epithelium by miR-195-3p. JOURNAL OF ETHNOPHARMACOLOGY 2024; 320:117413. [PMID: 37972911 DOI: 10.1016/j.jep.2023.117413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 10/26/2023] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Turmeric (Curcuma longa) has been used to treat gastrointestinal disorders in the Indian Ayurvedic medical system. According to the theory behind traditional Chinese medicine, turmeric can be distributed in the spleen meridian, for which it has been used as a digestive aid. Curcumin (Cur), a natural polyphenol compound originally derived from turmeric, has anti-inflammatory activity and can assist in treating inflammatory bowel disease. AIMS OF THE STUDY To investigate curcumin's protective effects on intestinal epithelium and explore the underlying miR-195-3p-related mechanisms. MATERIALS AND METHODS The miR-195-3p mimics were used to over-express miR-195-3p. The in vitro effects of Cur and miR-195-3p on the intestine were shown utilizing intestinal cryptlike epithelial cell line-6 (IEC-6) cells. By fasting for 48 h, an intestinal mucosal atrophy model of SD rats was created in vivo. Cur (25 or 50 mg/kg) was assessed for its protective effect on intestinal epithelium. Glycyrrhetinic acid (GA) with an intestinal protective effect reported in our previous research was adopted as a positive drug for the in vivo and in vitro bioactivity evaluation since there is no universally positive drug for either intestinal mucosal restitution or miR-195-3p modulation. RESULTS Cur protects the intestinal epithelium and promotes its repair after injury via down-regulating miR-195-3p. In vitro experiments showed that Cur inhibited the apoptosis of IEC-6 cells, stimulated their growth, and down-regulated the level of miR-195-3p in cells. When miR-195-3p was overexpressed, the viability of IEC-6 cells decreased while the apoptosis rate increased. All the above detrimental effects were alleviated after curcumin intervention. Moreover, Cur reversed the effect of miR-195-3p on its downstream occludin. In vivo, results showed that 48-h fasting impaired the integrity of the small intestinal mucosa (abnormal crypt structure and reduced goblet cell number), which was ameliorated by Cur treatment. In addition, the Cur treatment reversed both the increased expression level of miR-195-3p and decreased levels of ki-67 and occludin caused by fasting. CONCLUSIONS Cur could promote the proliferation and repair after injury of the intestinal mucosa by down-regulating miR-195-3p.

Abstract
Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis, is a chronic autoimmune disorder characterized by inflammation. However, currently available disease-modifying anti-IBD drugs exhibit limited efficacy in IBD therapy. Furthermore, existing therapeutic approaches provide only partial relief from IBD symptoms and are associated with certain side effects. In recent years, a novel category of nanoscale membrane vesicles, known as plant-derived exosome-like nanoparticles (PDENs), has been identified in edible plants. These PDENs are abundant in bioactive lipids, proteins, microRNAs, and other pharmacologically active compounds. Notably, PDENs possess immunomodulatory, antitumor, regenerative, and anti-inflammatory properties, making them particularly promising for the treatment of intestinal diseases. Moreover, PDENs can be engineered as targeted delivery systems for the efficient transport of chemical or nucleic acid drugs to the site of intestinal inflammation. In the present study, we provided an overview of PDENs, including their biogenesis, extraction, purification, and construction strategies, and elucidated their physiological functions and therapeutic effects on IBD. Additionally, we summarized the applications and potential of PDENs in IBD treatment while highlighting the future directions and challenges in the field of emerging nanotherapeutics for IBD therapy.

Abstract
Due to this becoming an aging society, the number of arthritis cases has been increasing. Unfortunately, some currently available medications can cause adverse effects. Using herbal remedies as a form of alternative medicine is becoming increasingly popular. Zingiber officinale (ZO), Curcuma longa (CL), and Kaempferia parviflora (KP) are herbal plants in the Zingiberaceae family that have potent anti-inflammatory effects. This study investigates the anti-inflammatory and chondroprotective effects of ZO, CL, and KP extracts on in vitro and ex vivo inflammatory models. The combinatorial anti-arthritis effect of each extract is also evaluated in an in vivo model. ZO extract preserves cartilaginous proteoglycans in proinflammatory cytokines-induced porcine cartilage explant in a fashion similar to that of CL and KP extracts and suppresses the expression of major inflammatory mediators in SW982 cells, particularly the COX2 gene. CL extract downregulates some inflammatory mediators and genes-associated cartilage degradation. Only KP extract shows a significant reduction in S-GAGs release in a cartilage explant model compared to the positive control, diacerein. In SW982 cells, it strongly suppresses many inflammatory mediators. The active constituents of each extract selectively downregulate inflammatory genes. The combined extracts show a reduction in inflammatory mediators to a similar degree as the combined active constituents. Reductions in paw swelling, synovial vascularity, inflammatory cell infiltration, and synovial hyperplasia are found in the combined extracts-treated arthritic rats. This study demonstrates that a combination of ZO, CL, and KP extracts has an anti-arthritis effect and could potentially be developed into an anti-arthritis cocktail for arthritis treatment.

Abstract
BACKGROUND Many eukaryote cells produce membrane-enclosed extracellular vesicles (EVs) to establish cell-to-cell communication. Plant-derived EVs (P-EVs) contain proteins, RNAs, lipids, and other metabolites that can be isolated from the juice, the flesh, and roots of many species. METHODS In the present review study, we studied numerous articles over the past two decades published on the role of P-EVs in plant physiology as well as on the application of these vesicles in different diseases. RESULTS Different types of EVs have been identified in plants that have multiple functions including reorganization of cell structure, development, facilitating crosstalk between plants and fungi, plant immunity, defense against pathogens. Purified from several edible species, these EVs are more biocompatible, biodegradable, and extremely available from many plants, making them useful for cell-free therapy. Emerging evidence of clinical and preclinical studies suggest that P-EVs have numerous benefits over conventional synthetic carriers, opening novel frontiers for the novel drug-delivery system. Exciting new opportunities, including designing drug-loaded P-EVs to improve the drug-delivery systems, are already being examined, however clinical translation of P-EVs-based therapies faces challenges. CONCLUSION P-EVs hold great promise for clinical application in the treatment of different diseases. In addition, despite enthusiastic results, further scrutiny should focus on unravelling the detailed mechanism behind P-EVs biogenesis and trafficking as well as their therapeutic applications.

Abstract
It is estimated that the prevalence rate of Alzheimer’s disease (AD) will double by the year 2040. Although currently available treatments help with symptom management, they do not prevent, delay the progression of, or cure the disease. Interestingly, a shared characteristic of AD and other neurodegenerative diseases and disorders is oxidative stress. Despite profound evidence supporting the role of oxidative stress in the pathogenesis and progression of AD, none of the currently available treatment options address oxidative stress. Recently, attention has been placed on the use of antioxidants to mitigate the effects of oxidative stress in the central nervous system. In preclinical studies utilizing cellular and animal models, natural antioxidants showed therapeutic promise when administered alone or in combination with other compounds. More recently, the concept of combination antioxidant therapy has been explored as a novel approach to preventing and treating neurodegenerative conditions that present with oxidative stress as a contributing factor. In this review, the relationship between oxidative stress and AD pathology and the neuroprotective role of natural antioxidants from natural sources are discussed. Additionally, the therapeutic potential of natural antioxidants as preventatives and/or treatment for AD is examined, with special attention paid to natural antioxidant combinations and conjugates that are currently being investigated in human clinical trials.

Abstract
For inflammatory bowel disease (IBD) therapy, systemic exposure of anti-TNF-α antibodies brought by current clinical injection always causes serious adverse effects. Colon-targeted delivery of anti-TNF-α antibodies through the oral route is of great importance but remains a formidable challenge. Here, we reported a biomimetic nanocomposite made of a ginger-derived exosome and an inorganic framework for this purpose. A large mesoporous silicon nanoparticle (LMSN) was uniquely customized for the antibody (infliximab, INF) to load it at high levels up to 61.3 wt% and prevent its aggregation. Exosome-like nanovesicles were isolated from ginger (GE) with a high-level production (17.5 mg kg-1). Then, ultrasound was used to coat GE onto the LMSN to obtain the biomimetic nanocomposite LMSN@GE. As expected, LMSN@GE showed advantages in the oral delivery of INF: stability in the gastrointestinal tract, colon-targeted delivery and high intestinal epithelium permeability. Amazingly, GE also presented an anti-inflammatory effect by blocking the NLRP3 inflammasome in addition to its delivery value. As a result, INF/LMSN@GE showed a significantly higher efficacy in colitis mice compared to the intravenously administered INF. This work provides new insights into colon-targeted delivery of anti-TNF-α antibodies via the oral route. Moreover, it puts forward a novel strategy for drug delivery using one therapeutic agent (herb-derived exosomes).

Abstract
BACKGROUND Knee osteoarthritis is the most common articular disease, and non-medical treatment of this disease has attracted the attention of researchers. The purpose of this study was to compare the effects of aromatherapy and massage therapy on knee pain, morning stiffness, daily life function, and quality of life in patients with knee osteoarthritis. METHODS This is a clinical trial. In this study, 93 patients referred to the Imam Ali Hospital (Physical Therapy Clinic) who entered the study were randomly divided into three groups including massage therapy (n = 31), aromatherapy (n = 31), and the control (n = 31). The data gathering tools were a demographic characteristics questionnaire and the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. The questionnaire was completed before intervention and at the 5th and 10th sessions after intervention in all three groups. Data were analyzed by SPSS software version 20, and Chi-square, Fisher's exact test, repeated measures test, one-way ANOVA test, and Tukey's post hoc test were used for analysis. RESULTS The study shows that mean score subscale Symptoms and dryness in the 5th session and 10th session of intervention in the aromatherapy group is significantly higher than in the control group (p < 0.05). The massage therapy group had the highest pain score at the beginning of the intervention, but at the end of the 10th session of intervention had the least pain score. Mean score subscale Performance of daily life in the 5th session and 10th session of intervention in the aromatherapy group is significantly higher than in the control group (p < 0.05). Mean score in the subscale Performance, exercise, and recreational activities significantly differs between the aroma therapy and massage therapy groups compared with the control group in all times of interventions (p < 0.05), and in the mean score in the subscale Quality of life, there is no significant difference between the groups in all times of interventions (p > 0.05). CONCLUSION The use of both massage therapy and aromatherapy is recommended for patients with knee osteoarthritis. Interventions should be prolonged for at least 6 months in patients so their effects appear on the patient.

Abstract
Reproductive senescence is accompanied by a reduced number and quality of ovarian follicles in response to the accumulation of free radicals and the process of apoptosis. Having selected mice as models, we examined the hypothesis that curcumin as an antioxidant and anti-inflammatory agent might prevent or retard ovarian aging. Female NMRI 21-day-old mice were divided into control, vehicle and curcumin groups. In the treatment group the mice received curcumin at 100mgkg-1day-1 intraperitoneally. After 6, 12 and 33 weeks several parameters were examined including ovarian reserve, oocyte quality, oxidative status, invitro fertilisation and expression of ovulation-related (growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15)) and anti-aging-related (sirtuin 1 (SIRT-1) and SIRT-3) genes. Curcumin treatment up to 12 and 33 weeks resulted in increased ovarian volume and number of follicles and was associated with elevated anti-Müllerian hormone and oestrogen and diminished FSH serum levels. Furthermore, enhanced oocyte maturation, fertilisation and embryo development plus reduced oxidative stress were seen in the curcumin group. Also, the expression of GDF-9, BMP-15, SIRT-1 and SIRT-3 genes was increased in the curcumin group. Concerning gestational age, the findings of the study suggested that administration of curcumin could delay the process of oocyte aging in a mouse model.

Abstract
Ginger (Zingiber officinale Roscoe) has been used as a food, spice, supplement and flavoring agent and in traditional medicines due to its beneficial characteristics such as pungency, aroma, nutrients and pharmacological activity. Ginger and ginger extracts were reported to have numerous effects, such as those on diabetes and metabolic syndrome, cholesterol levels and lipid metabolism, and inflammation, revealed by epidemiological studies. To understand the beneficial characteristics of ginger, especially its physiological and pharmacological activities at the molecular level, the biological effects of ginger constituents, such as monoterpenes (cineole, citral, limonene and α/β-pinenes), sesquiterpenes (β-elemene, farnesene and zerumbone), phenolics (gingerols, [6]-shogaol, [6]-paradol and zingerone) and diarylheptanoids (curcumin), and the associated signaling pathways are summarized. Ginger constituents are involved in biological activities, such as apoptosis, cell cycle/DNA damage, chromatin/epigenetic regulation, cytoskeletal regulation and adhesion, immunology and inflammation, and neuroscience, and exert their effects through specific signaling pathways associated with cell functions/mechanisms such as autophagy, cellular metabolism, mitogen-activated protein kinase and other signaling, and development/differentiation. Estrogens, such as phytoestrogens, are one of the most important bioactive materials in nature, and the molecular mechanisms of estrogen actions and the assays to detect them have been discussed. The molecular mechanisms of estrogen actions induced by ginger constituents and related applications, such as the chemoprevention of cancers, and the improvement of menopausal syndromes, osteoporosis, endometriosis, prostatic hyperplasia, polycystic ovary syndrome and Alzheimer's disease, were summarized by a comprehensive search of references to understand more about their health benefits and associated health risks.

Abstract
Various studies have investigated the effect of diet on rheumatoid arthritis (RA) as a complimentary treatment along with standard drug therapy. Various types of diet have been investigated. Fasting, the Mediterranean diet, the Cretan Mediterranean diet, vegetarian diet, an anti-inflammatory diet and the use of various specific food substances have been in the focus of research interest. The relationship of obesity with disease activity in RA has also been investigated. A period of fasting followed by Mediterranean diet, the Cretan Mediterranean diet and an anti-inflammatory diet have been found to have a beneficial effect on disease activity in RA. Obesity has been found to be associated with increased disease activity in RA. However, weight loss appears to be related to increased mortality in RA. The use of flavonoids, resveratrol and curcumin may have a beneficial effect in RA. It appears that diet may aid in RA management as a complimentary factor to standard drug treatment.

[PMID: 31121820 PMCID: PMC6571963 DOI: 10.3390/molecules24101964] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 05/10/2019] [Accepted: 05/15/2019] [Indexed: 12/11/2022] Open
Abstract
The natural compound Zerumbone (hereinafter referred to as ZER), a monocyclic sesquiterpenoid, has been reported to possess many pharmacological properties, including antioxidant and anti-inflammatory properties. This study aimed to investigate the underlying mechanism of ZER against acute liver injury (ALI) in CCl4-induced mice models. ICR mice were pretreated intraperitoneally with ZER for five days, then received a CCl4 injection two hours after the last ZER administration and were sacrificed 24 h later. Examination of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and the histopathological analysis confirmed the hepatoprotective effect of ZER. Biochemical assays revealed that ZER pretreatment recovered the activities of antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), restored the glutathione (GSH) reservoir, and reduced the production of malondialdehyde (MDA), all in a dose-dependent manner. Furthermore, administration of ZER in vivo reduced the release amounts of pro-inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) and inhibited the increased protein levels of Toll-like receptor 4 (TLR4), nuclear factor-kappaB (NF-κB) p-p65, and cyclooxygenase (COX-2). Further studies in lipopolysaccharide (LPS)-induced Raw264.7 inflammatory cellular models verified that ZER could inhibit inflammation via inactivating the TLR4/NF-κB/COX-2 pathway. Thus, our study indicated that ZER exhibited a hepatoprotective effect against ALI through its antioxidant and anti-inflammatory activities and the possible mechanism might be mediated by the TLR4/NF-κB/COX-2 pathway. Collectively, our studies indicate ZER could be a potential candidate for chemical liver injury treatment.

Abstract
Gingerols and shogaols are recognized as active ingredients in ginger and exhibit diverse pharmacological activities. The preclinical pharmacokinetics and tissue distribution investigations of gingerols and shogaols in rats remain less explored, especially for the simultaneous analysis of multi-components. In this study, a rapid, sensitive, selective, and reliable method using an Ultra-Performance Liquid Chromatography Q-Exactive High-Resolution Mass Spectrometer (UPLC-Q-Exactive⁻HRMS) was established and validated for simultaneous determination of eight compounds, including 6-gingerol, 6-shogaol, 8-gingerol, 8-shogaol, 10-gingerol, 10-shogaol, Zingerone, and 6-isodehydrogingenone in plasma and tissues of rats. The analytes were separated on a Syncronis C18 column (100 × 2.1 mm, 1.7 µm) using a gradient elution of acetonitrile and 0.1% formic acid in water at a flow rate of 0.25 mL/min at 30 °C. The method was linear for each ingredient over the investigated range with all correlation coefficients greater than 0.9910. The lowest Lower Limit of quantitation (LLOQ) was 1.0 ng/mL. The intra- and inter-day precisions (Relative Standard Deviation, RSD%) were less than 12.2% and the accuracy (relative error, RE%) ranged from -8.7% to 8.7%. Extraction recovery was 91.4⁻107.4% and the matrix effect was 86.3⁻113.4%. The validated method was successfully applied to investigate the pharmacokinetics and tissue distribution of eight components after oral administration of ginger extract to rats. These results provide useful information about the pharmacokinetics and biodistribution of the multi-component bioactive ingredients of ginger in rats and will contribute to clinical practice and the evaluation of the safety of a Chinese herbal medicine.

Protective and therapeutic potential of ginger (Zingiber officinale) extract and [6]-gingerol in cancer: A comprehensive review. Phytother Res 2018; 32:1885-1907.

Abstract
Natural dietary agents have attracted considerable attention due to their role in promoting health and reducing the risk of diseases including cancer. Ginger, one of the most ancient known spices, contains bioactive compounds with several health benefits. [6]-Gingerol constitutes the most pharmacologically active among such compounds. The aim of the present work was to review the literature pertaining to the use of ginger extract and [6]-gingerol against tumorigenic and oxidative and inflammatory processes associated with cancer, along with the underlying mechanisms of action involved in signaling pathways. This will shed some light on the protective or therapeutic role of ginger derivatives in oxidative and inflammatory regulations during metabolic disturbance and on the antiproliferative and anticancer properties. Data collected from experimental (in vitro or in vivo) and clinical studies discussed in this review indicate that ginger extract and [6]-gingerol exert their action through important mediators and pathways of cell signaling, including Bax/Bcl2, p38/MAPK, Nrf2, p65/NF-κB, TNF-α, ERK1/2, SAPK/JNK, ROS/NF-κB/COX-2, caspases-3, -9, and p53. This suggests that ginger derivatives, in the form of an extract or isolated compounds, exhibit relevant antiproliferative, antitumor, invasive, and anti-inflammatory activities.

Abstract
The anti-diabetic activity of ginger powder (Zingiber officinale) has been recently promoted, with the recommendation to be included as one of the dietary supplements for diabetic patients. However, previous studies presented different results, which may be caused by degradation and metabolic changes of ginger components, gingerols, shogaols and paradols. Therefore, we prepared 10 ginger active components, namely 6-, 8-, 10-paradols, 6-, 8-, 10-shogaols, 6-, 8-, 10-gingerols and zingerone, and evaluated their anti-hyperglycemic activity. Among the tested compounds, 6-paradol and 6-shogaol showed potent activity in stimulating glucose utilization by 3T3-L1 adipocytes and C2C12 myotubes. The effects were attributed to the increase in 5' adenosine monophosphate-activated protein kinase (AMPK) phosphorylation in 3T3-L1 adipocytes. 6-Paradol, the major metabolite of 6-shogaol, was utilized in an in vivo assay and significantly reduced blood glucose, cholesterol and body weight in high-fat diet-fed mice.

Abstract
There is a clinical need for new, more effective treatments for chronic and debilitating inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. In this study, we characterized a specific population of nanoparticles derived from edible ginger (GDNPs 2) and demonstrated their efficient colon targeting following oral administration. GDNPs 2 had an average size of ∼230 nm and exhibited a negative zeta potential. These nanoparticles contained high levels of lipids, a few proteins, ∼125 microRNAs (miRNAs), and large amounts of ginger bioactive constituents (6-gingerol and 6-shogaol). We also demonstrated that GDNPs 2 were mainly taken up by intestinal epithelial cells (IECs) and macrophages, and were nontoxic. Using different mouse colitis models, we showed that GDNPs 2 reduced acute colitis, enhanced intestinal repair, and prevented chronic colitis and colitis-associated cancer (CAC). 2D-DIGE/MS analyses further identified molecular target candidates of GDNPs 2 involved in these mouse models. Oral administration of GDNPs 2 increased the survival and proliferation of IECs and reduced the pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β), and increased the anti-inflammatory cytokines (IL-10 and IL-22) in colitis models, suggesting that GDNPs 2 has the potential to attenuate damaging factors while promoting the healing effect. In conclusion, GDNPs 2, nanoparticles derived from edible ginger, represent a novel, natural delivery mechanism for improving IBD prevention and treatment with an added benefit of overcoming limitations such as potential toxicity and limited production scale that are common with synthetic nanoparticles.

Abstract
Diabetes mellitus (DM) remains a major health care problem worldwide both in developing and developed countries. Many factors, including age, obesity, sex, and diet, are involved in the etiology of DM. Nowadays, drug and dietetic therapies are the two major approaches used for prevention and control of DM. Compared to drug therapy, a resurgence of interest in using diet to manage and treat DM has emerged in recent years. Conventional dietary methods to treat DM include the use of culinary herbs and/or spices. Spices have long been known for their antioxidant, anti-inflammatory, and anti-diabetic properties. This review explores the anti-diabetic properties of commonly used spices, such as cinnamon, ginger, turmeric, and cumin, and the use of these spices for prevention and management of diabetes and associated complications.

Abstract
BACKGROUND Patients who undergo surgery appear to use dietary supplements significantly more frequently than the general population. Because they contain pharmacologically active compounds, dietary supplements may affect coagulation and platelet function during the perioperative period through direct effects, pharmacodynamic interactions, and pharmacokinetic interactions. However, in this regard, limited studies have been conducted that address the pharmacological interactions of dietary supplements. To avoid possible bleeding risks during surgery, information of potential complications of dietary supplements during perioperative management is important for physicians. METHODS Through a systematic database search of all available years, articles were identified in this review if they included dietary supplements and coagulation/platelet function, while special attention was paid to studies published after 1990. RESULTS Safety concerns are reported in commercially available dietary supplements. Effects of the most commonly used natural products on blood coagulation and platelet function are systematically reviewed, including 11 herbal medicines (echinacea, ephedra, garlic, ginger, ginkgo, ginseng, green tea, kava, saw palmetto, St John's wort, and valerian) and 4 other dietary supplements (coenzyme Q10, glucosamine and chondroitin sulfate, fish oil, and vitamins). Bleeding risks of garlic, ginkgo, ginseng, green tea, saw palmetto, St John's wort, and fish oil are reported. Cardiovascular instability was observed with ephedra, ginseng, and kava. Pharmacodynamic and pharmacokinetic interactions between dietary supplements and drugs used in the perioperative period are discussed. CONCLUSIONS To prevent potential problems associated with the use of dietary supplements, physicians should be familiar with the perioperative effects of commonly used dietary supplements. Since the effects of dietary supplements on coagulation and platelet function are difficult to predict, it is prudent to advise their discontinuation before surgery.

Abstract
Context: Ginger is the rhizome of Zingiber officinale, a perennial plant, used alone or in compounds as a spice or remedy in ancient recipes of Iranian traditional medicine (ITM) as an effective tonic for the memory and digestive system, the opener of hepatic obstructions, aphrodisiac, for expelling compact wind from stomach and intestines, diluting, desiccating and emollient of phlegmatic and compact humor sticking to body organs, stomach, intestine, brain and throat. The ITM scholars believed that ginger was a vermifuge as well as a remedy for paralysis and obstructive jaundice. They also revealed that this phytomedicine cures diarrhea due to corrupted food. This study aimed to compare the medicinal properties (afaal) of ginger in ITM with those indicated in modern research. Results: Results of this study showed that the modern phytotherapy confirmed some of the properties of ginger. In addition, some of the properties of this phytomedicine have not been studied yet. Conclusions: By studding the ITM literature, herb elements or in other words ITM keywords, researchers can predict and state some unknown or less known potential pharmacologic effects of medicinal plants.

Abstract
Ginger (the rhizome of Zingiber officinale Roscoe) has been used worldwide for many centuries in cooking and for treatment of several diseases. The main pharmacological properties of ginger include anti-inflammatory, antihyperglycemic, antiarthritic, antiemetic and neuroprotective actions. Recent studies demonstrated that ginger significantly enhances cognitive function in various cognitive disorders as well as in healthy brain. However, the biochemical mechanisms underlying the ginger-mediated enhancement of cognition have not yet been studied in normal or diseased brain. In the present study, we assessed the memory-enhancing effects of dried ginger extract (GE) in a model of scopolamine-induced memory deficits and in normal animals by performing a novel object recognition test. We found that GE administration significantly improved the ability of mice to recognize novel objects, indicating improvements in learning and memory. Furthermore, to elucidate the mechanisms of GE-mediated cognitive enhancement, we focused on nerve growth factor (NGF)-induced signaling pathways. NGF enzyme-linked immunosorbent assay analysis revealed that GE administration led to elevated NGF levels in both the mouse hippocampus and rat glioma C6 cells. GE administration also resulted in phosphorylation of extracellular-signal-regulated kinase (ERK) and cyclic AMP response element-binding protein (CREB), as revealed by Western blotting analysis. Neutralization of NGF with a specific NGF antibody inhibited GE-triggered activation of ERK and CREB in the hippocampus. Also, GE treatment significantly increased pre- and postsynaptic markers, synaptophysin and PSD-95, which are related to synapse formation in the brain. These data suggest that GE has a synaptogenic effect via NGF-induced ERK/CREB activation, resulting in memory enhancement.

Abstract
Curcumin, an agent traditionally utilized for its preventative action against tumorigenesis, oxidation, inflammation, apoptosis and hyperlipemia, has also been used in the treatment of Alzheimer's disease (AD). Recent advances in the study of AD have revealed astrocytes (AS) as being key factors in the early pathophysiological changes in AD. Glial fibrillary acidic protein (GFAP), a marker specific to AS, is markedly more manifest during morphological modifications and neural degeneration signature during the onset of AD. Several studies investigating the functionality of curcumin have shown that it not only inhibits amyloid sedimentation but also accelerates the disaggregation of amyloid plaque. Thus, we are interested in the relationship between curcumin and spatial memory in AD. In this study, we intend to investigate the effects of curcumin in amyloid-β (Aβ(1-40)) induced AD rat models on both the behavioral and molecular levels, that is to say, on their spatial memory and on the expression of GFAP in their hippocampi. Our results were statistically significant, showing that the spatial memory of AD rats improved following curcumin treatment (p < 0.05), and that the expression of GFAP mRNA and the number of GFAP positive cells in the curcumin treated rats was decreased relative to the AD group rats (p < 0.05). Furthermore, the expression level of GFAP mRNA in hippocampal AS in the AD rats significantly increased when compared with that in the sham control (p < 0.05). Taken together, these results suggest that curcumin improves the spatial memory disorders (such disorders being symptomatic of AD) in Aβ(1-40)-induced rats by down regulating GFAP expression and suppressing AS activity.

Abstract
Aqueous extracts of Zingiber officinale rhizomes were studied to evaluate their antidiabetic effects on protein glycation and on the diffusion of glucose in vitro in the present study. Zingiber officinale rhizome aqueous extract were examined at concentrations of 5, 10, 20 and 40 g/L. The antidiabetic effects were found to be dose-dependent. Antidiabetic potential of Zingiber officinale was mainly through inhibition of the glucose diffusion and to a limited extent by reducing the glycation. However, further studies are needed to determine in vitro effects of therapeutic potential by restraining postprandial glucose absorptions and plasma protein glycations in diabetic subjects.

Abstract
In the United States, many patients, including cancer patients, concurrently take prescription drugs and herbal supplements. Co-administration of prescription medicines and herbal supplements may have negative outcomes via pharmacodynamic and pharmacokinetic herb-drug interactions. However, multiple constituents in botanicals may also yield beneficial pharmacological activities. Botanicals could possess effective anticancer compounds that may be used as adjuvants to existing chemotherapy to improve efficacy and/or reduce drug-induced toxicity. Herbal medicines, such as ginseng, potentiated the effects of chemotherapeutic agents via synergistic activities, supported by cell cycle evaluations, apoptotic observations, and computer-based docking analysis. Since botanicals are nearly always administrated orally, the role of intestinal microbiota in metabolizing ginseng constituents is presented. Controlled clinical studies are warranted to verify the clinical utility of the botanicals in cancer chemoprevention.

Abstract
Imbalance or malfunction of the immune systems is associated with a range of chronic diseases including autoimmune diseases, allergies, cancers and others. Various innate and adaptive immune cells that are integrated in this complex networking system may represent promising targets for developing immunotherapeutics for treating specific immune diseases. A spectrum of phytochemicals have been isolated, characterized and modified for development and use as prevention or treatment of human diseases. Many cytotoxic drugs and antibiotics have been developed from phytocompounds, but the application of traditional or new medicinal plants for use as immunomodulators in treating immune diseases is still relatively limited. In this review, a selected group of medicinal herbs, their derived crude or fractionated phytoextracts and the specific phytochemicals/phytocompounds isolated from them, as well as categorized phytocompound groups with specific chemical structures are discussed in terms of their immunomodulatory bioactivities. We also assess their potential for future development as immunomodulatory or inflammation-regulatory therapeutics or agents. New experimental approaches for evaluating the immunomodulatory activities of candidate phytomedicines are also discussed.

Abstract
Dried flowers and buds of Sophora japonica (Huaihua) are used in China, Japan and Korea for treating haematemesis and bleeding haemorrhoids. This study compared the clinical safety and efficacy of a Sophora flower formula with a placebo for the conservative treatment of symptomatic haemorrhoids. The study was a prospective, double-blind, randomized placebo-controlled trial. The clinical effective rate, symptom score and the incidence of important clinical events were used as observation indices to evaluate the effect of the Sophora flower formula. The results showed that after 7 days of treatment, improvement was observed in 87.0% of the patients' major symptoms in the Sophora flower formula group compared with 81.8% of those in the placebo group. After 14 days, 78.2% patients in the Sophora flower formula group were asymptomatic, whereas 40.9% of those in the placebo group exhibited residual symptoms. However, the difference between both groups was not statistically significant. As the bowel habits of the patients improved and as the patients took sitz baths, their symptoms improved drastically, regardless of the use of the Sophora flower formula. These findings indicate that the traditional Chinese Sophora flower formula is clinically safe; however, its effects on haemorrhoids need to be studied in a larger sample size and with different dosages. The present study results may be a potential clinical reference for physicians prescribing medications for patients with symptomatic haemorrhoids.
