Abstract
Hangeshashinto has attracted attention owing to its potential to prevent chemotherapy-induced diarrhea. However, studies on the efficacy of Hangeshashinto have had conflicting results. Evaluating the efficacy of Hangeshashinto may contribute to reducing the use and adverse events caused by drug therapy for chemotherapy-induced diarrhea. Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, Ichushi, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov were searched to retrieve all the relevant studies. Randomized controlled trials (RCTs) comparing the administration of Hangeshashinto with that of other treatments in patients with cancer receiving chemotherapy were included. The primary outcome was severe (grade 3-4) diarrhea assessed using the Common Terminology Criteria for Adverse Events. The secondary outcome was mild (grade 0-2) diarrhea. Out of 324 records identified, three studies were selected for the meta-analysis. Irinotecan was used for chemotherapy in all these studies. Hangeshashinto did not reduce the incidence of severe diarrhea compared with other treatments (risk ratio (RR) 0.40, 95% confidence interval (CI) 0.11-1.41, P = 0.15; low-quality evidence). Moreover, Hangeshashinto did not reduce the incidence of mild diarrhea (RR 1.35, 95% CI 0.87-2.09, P = 0.18; low-quality evidence). However, in the subgroup analysis compared with no treatment, the Hangeshashinto group had a significantly lower incidence of severe diarrhea (RR 0.17, 95% CI 0.03-0.88, P = 0.03; low-quality evidence). At present, insufficient evidence exists to support the claim that Hangeshashinto prevents diarrhea caused by irinotecan-based chemotherapy.

Abstract
OBJECTIVE To evaluate the antidiarrheal effect of ethanol extract of Glycyrrhiza uralensis Fisch root (GFR) in vivo and jejunal contraction in vitro. METHODS In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl2 was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca2+-free-high-K+ solution containing ethylene diamine tetraacetic acid (EDTA). RESULTS GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC50) values was 1.05 (0.71-1.24), 0.34 (0.29-0.41) and 0.15 (0.11-0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl2 down to the right, showing a similar effect to verapamil. CONCLUSIONS GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca2+ channels and muscarinic receptors.

Abstract
Cancer therapy-induced oral mucositis (OM) is one of the most troublesome morbidities after radio-chemotherapy. Age, nutritional status, tumor type, oral hygiene, and treatment method are the determinants for OM incidence. In addition, oxygen-free radicals can act as a trigger for an inflammatory milieu that causes OM. Based on the debilitating nature of OM, finding a safe and inexpensive agent with anti-inflammatory, anti-microbial, and antioxidative properties can be valuable for this situation. Considering the harmful effects of some chemical agents, herbal medicine has been suggested as a potential alternative owing to unique properties such as safety, availability and low cost. Many studies have illustrated several pharmacological properties of herbal medicines in recent years, such as anti-inflammatory, anti-microbial, and antioxidative activities, which are essential factors in the palliation of cancer therapy-induced OM. This review aimed to evaluate herbal medicines' effects on cancer therapy-induced OM. According to this comprehensive review, it is concluded that medicinal plants and phytochemicals can be used as practical agents in the palliation of cancer therapy-induced OM without any serious side effects.

Anti-diarrheal therapeutic potential of diminazene aceturate stimulation of the ACE II/Ang-(1-7)/Mas receptor axis in mice: A trial study. Biochem Pharmacol 2021; 186:114500. [PMID: 33684388 DOI: 10.1016/j.bcp.2021.114500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 02/17/2021] [Accepted: 02/26/2021] [Indexed: 11/17/2022]
Abstract
The angiotensin (Ang) II converting enzyme (ACE II) pathway has recently been shown to be associated with several beneficial effects on the body, especially on the cardiac system and gastrointestinal tract. ACE II is responsible for converting Ang II into the active peptide Ang-(1-7), which in turn binds to a metabotropic receptor, the Mas receptor (MasR). Recent studies have demonstrated that Diminazene Aceturate (DIZE), a trypanosomicide used in animals, activates the ACE II pathway. In this study, we aimed to evaluate the antidiarrheal effects promoted by the administration of DIZE to activate the ACE II/Ang-(1-7)/MasR axis in induced diarrhea mice models. The results show that activation of the ACE II pathway exerts antidiarrheal effects that reduce total diarrheal stools and enteropooling. In addition, it increases Na+/K+-ATPase activity and reduces gastrointestinal transit and thus inhibits contractions of intestinal smooth muscle; decreases transepithelial electrical resistance, epithelial permeability, PGE2-induced diarrhea, and proinflammatory cytokines; and increases anti-inflammatory cytokines. Enzyme-linked immunosorbent assay (ELISA) demonstrated that DIZE, when activating the ACE II/Ang-(1-7)/MasR axis, can still interact with GM1 receptors, which reduces cholera toxin-induced diarrhea. Therefore, activation of the ACE II/Ang-(1-7)/MasR axis can be an important pharmacological target for the treatment of diarrheal diseases.

Biopolymer Extracted from Anadenanthera colubrina (Red Angico Gum) Exerts Therapeutic Potential in Mice: Antidiarrheal Activity and Safety Assessment. Pharmaceuticals (Basel) 2020; 13:ph13010017.

Abstract
Anadenanthera colubrina var. cebil (Griseb.) Altschul (Fabaceae family), commonly known as the red angico tree, is a medicinal plant found throughout Brazil’s semi-arid area. In this study, a chemical analysis was performed to investigate the antidiarrheal activity and safety profile of red angico gum (RAG), a biopolymer extracted from the trunk exudate of A. colubrina. Upon FT-IR spectroscopy, RAG showed bands in the regions of 1608 cm−1, 1368 cm−1, and 1029 cm−1, which relate to the vibration of O–H water molecules, deformation vibration of C-O bands, and vibration of the polysaccharide C-O band, respectively, all of which are relevant to glycosidic bonds. The peak molar mass of RAG was 1.89 × 105 g/mol, with the zeta potential indicating electronegativity. RAG demonstrated high yield and solubility with a low degree of impurity. Pre-treatment with RAG reduced the total diarrheal stool and enteropooling. RAG also enhanced Na+/K+-ATPase activity and reduced gastrointestinal transit, and thereby inhibited intestinal smooth muscle contractions. Enzyme-Linked Immunosorbent Assay (ELISA) demonstrated that RAG can interact with GM1 receptors and can also reduce E. coli-induced diarrhea in vivo. Moreover, RAG did not induce any signs of toxicity in mice. These results suggest that RAG is a possible candidate for the treatment of diarrheal diseases.

Abstract
Scutellaria baicalensis (S. baicalensis) has been used to manage diarrhea, and its anti-inflammatory effects are responsible for anti-diarrheal effects. However, there are no data concerning its direct effect on colonic motility. Therefore, the effects of the major components of S. baicalensis (baicalin, baicalein and wogonin) on colonic motility were investigated. A segment of the distal colon of rats was placed in Krebs solution to monitor spontaneous giant contractions (GCs). Changes in GCs were recorded after applying baicalin, baicalein or wogonin. After pretreatment with Nω-nitro-L-arginine methyl ester hydrochloride (L-NAME), 1H-(1,2,4)-oxadiazolo (4,2-a) quinoxalin-1-one (ODQ), tetradotoxin, w-conotoxin, apamin, and iberiotoxin, changes in GCs by wogonin were recorded and analyzed. The segment of the distal colon showed spontaneous GCs at a mean amplitude of 3.7±0.3 g with a frequency of 0.8±0.1/min. Baicalin, baicalein, and wogonin reduced both the amplitude and the frequency of GCs in a dose-dependent manner. Wogonin had the most potent inhibitory effect on GCs (IC50 was 14.6 µM in amplitude and 14.2 µM in frequency). Wogonin-induced GC reduction was not significantly affected by the inhibition of nitric oxide/cGMP pathways with L-NAME and ODQ. Blocking the enteric neurotransmission with tetradotoxin and ω-conotoxin was ineffective on the wogonin-induced reduction of GCs. Ca2+-activated K+ (KCa) channel blockers (apamin and iberiotoxin) significantly attenuated the inhibitory effects of wogonin on GCs (P<0.01). Wogonin was effective in inhibiting colonic motility, probably through the opening of KCa channels located in the smooth muscle apparatus. These findings suggest that wogonin may be a candidate drug for the management of dysmotility-related diarrhea.

Abstract
Diarrhea is one of the leading causes of infant death in the world accounting for high child mortality rate. It is also present in different pathophysiologies related to several etiological agents. The aim of this study is to investigate the antidiarrheal effect of α -Terpineol (α-TPN) in different diarrhea models in rodents. The antidiarrheal effect of α-TPN in the treatment of acute diarrhea and enteropooling induced by castor oil or PGE2 in Swiss mice pretreated orally with saline (NaCl 0.9%), Loperamide (5 mg/kg) and α-TPN (6.25, 12.5, 25 and 50 mg/kg) was analyzed. Additionally, parameters of severity, total weight of faeces and post-treatment for 4 h were evaluated. Modulation of the opioid and cholinergic pathways was performed and intestinal transit model using activated charcoal as marker was also used. The effect of α-TPN on secretory diarrhea was investigated using the model of fluid secretion in intestinal loops isolated from cholera toxin-treated mice. α-TPN showed antidiarrheal effect (*p < 0.05), reducing the total stool amount (*55%, *48%, *44%, *24%) and diarrheal (*47%, *66%; *56%, 10%) respectively for the doses tested. All doses investigated in the enteropooling test presented significant changes (*46%, *78%, *66%, *41% respectively) in relation to the control. α-TPN through the muscarinic pathway reduced the gastrointestinal transit (*31%), besides inhibiting PGE2-induced diarrhea (*39%). α-TPN also reduced fluid formation and loss of Cl- ions, by interacting directly with GM1 receptors and cholera toxin, thus increasing the uptake of intestinal fluids. The results suggest an anti-diarrheal activity of α-TPN due to its anticholinergic action, ability to block PGE2 and GM1 receptors and interaction with cholera toxin in secretory diarrhea, making it a promising candidate drug for the treatment of diarrheal diseases.

Abstract
Objective:
Oral mucositis and diarrhea are adverse effects (AEs) of chemotherapy and chemoradiotherapy (CR/CRT) that commonly occur in patients of esophageal cancer (EC). We investigated whether Hangeshashinto (TJ-14)—a Japanese traditional medicine—could control oral mucositis, pain, incidence of esophagitis, and diarrhea in patients who underwent CT/CRT for EC.
Methods:
We enrolled 39 patients (36 men, 3 women) who underwent docetaxel- or cisplatin-based CT/CRT for EC between July 2012 and June 2014, of whom 19 used TJ-14 dissolved in water as an oral rinse 3 times a day over the first 2 courses of their treatment, and 20 (the control group) received no particular prophylaxis against mucositis. Their AEs, including mucositis, were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.
Results:
Although incidences of oral mucositis, appetite loss, nausea, constipation, and vomiting did not significantly differ between the TJ-14 group and controls, diarrhea incidence was significantly lower in the TJ-14 group by the second treatment course (P = 0.0261 by per protocol set analyses).
Conclusions:
TJ-14 significantly decreases diarrhea caused by CT/CRT in patients treated for EC, although TJ-14 cannot prevent of causing oral mucositis.

Abstract
Background: The current pooled analysis evaluated the efficacy of Hangeshashinto (TJ-14) in the prevention and/or treatment of chemotherapy-induced oral mucositis (COM) in gastric cancer and colorectal cancer using two prospective, multi-institutional, randomized, double-blind, placebo-controlled phase II trials. Patients and Methods: HANGESHA-G and HANGESHA-C randomly assigned patients with gastric cancer or colorectal cancer who developed moderate to severe COM (grade ≥1) during any cycle of chemotherapy to receive either TJ-14 or a placebo as a double-blind trial. The patients received a placebo or TJ-14 for four to six weeks, according to the chemotherapy regimen, from the start of their next course of chemotherapy. The primary endpoint was the incidence of grade ≥2 COM in the protocol treatment course, and the secondary endpoints were the time to disappearance of COM and the incidence of adverse events. Results: The pooled population included 181 patients. The incidence of grade ≥2 COM in the TJ-14 group was 55.7% (49 patients), while that in the placebo group was 53.8% (50 patients); there was no significant difference between the two groups (p=0.796). The median time to remission of grade ≥2 COM to grade <1 was 8 days in the TJ-14 group and 15 days in the placebo group (p= 0.072). The hazard ratio was 1.54 [1.02 to 2.31] in favor of TJ-14. Treatment with TJ-14 was associated with marginally significant reduction in the duration of severe grade ≥2 COM in comparison to patients receiving placebo indicating the effect of TJ-14 in reducing the severity of COM. Conclusion: The present-pooled analysis showed that TJ-14 had a treatment effect in gastric cancer and colorectal cancer patients with COM in comparison to a placebo. Further phase III studies with a larger sample size are needed to clarify the protective effects of TJ-14 against COM.

Abstract
BACKGROUND In this ethnopharmacological study, methanolic extract of the aerial plant parts of Phragmites karka (Family: Poaceae) and its petroleum ether and carbon tetrachloride fractions were investigated for bioactivities in Swiss-albino mice, namely, analgesic, central nervous system (CNS) depressant, hypoglycemic, and antidiarrheal activity. METHODS The cold methanolic extract of the aerial plant parts of Phragmites karka (MEPK) was first prepared, and it was then further fractionated as petroleum ether (PEFMEPK) and carbon tetrachloride (CTFMEPK) fractions. Analgesic activity was performed employing acidic acid-induced writhing test, central analgesic effect by radiant heat tail-flick method. CNS depressant activity was evaluated by phenobarbitone-induced sleeping time test. Hypoglycemic activity was tested by glucose tolerance test (GTT). Antidiarrheal activity was evaluated by castor oil-induced diarrhea method. For all in vivo tests, doses of 200 and 400 mg/kg body weight were used. RESULTS In the mice model, the MEPK, PEFMEPK, and CTFMEPK fractions showed significant peripheral analgesic activity at a dose of 400 mg/kg body weight with percentage of inhibition of acetic acid-induced writhing 77.67 (p<0.001), 33.50 (p<0.001), and 40.29 (p<0.001), respectively, compared to the standard dichlofenac (60.68%, p<0.001) group. The hypoglycemic properties of MEPK, PEFMEPK, and CTFMEPK extracts were evaluated in normoglycemic mice where the reduction of blood glucose level after 30 min of glucose load were 69.85%, 78.91%, and 72.73%, respectively, and for standard glibenclamide, the reduction was 72.85%. All results were significant (p<0.05). In the case of the CNS depressant activity by phenobarbitone-induced sleeping time test, the crude ME significantly reduced sleep latency by 57.14% and increased the duration of sleep by 63.29% compared to the control, which were comparable to that of standard diazepam (65.71% and 77.62%, respectively). Among all the extract and fractions, methanolic extract showed the maximum antidiarrheal effect. The methanolic extract at 200 mg/kg dose induced a significant decrease in the total number of defecation in 4 h (69.05% of inhibition, p<0.001) and at 400 mg/kg dose showed 76.19% of inhibition (p<0.001). CONCLUSIONS In light of the available literature, these findings represent the first experimental investigation of biological activities of P. karka in the perspective of their traditional use.

Banhasasim-Tang Treatment Reduces the Severity of Esophageal Mucosal Ulcer on Chronic Acid Reflux Esophagitis in Rats. BIOMED RESEARCH INTERNATIONAL 2017; 2017:7157212. [PMID: 28349065 PMCID: PMC5352876 DOI: 10.1155/2017/7157212] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2016] [Revised: 02/06/2017] [Accepted: 02/13/2017] [Indexed: 12/16/2022]
Abstract
The present study was conducted to evaluate both antioxidant and anti-inflammatory activity of Banhasasim-tang (BHSST) on chronic acid reflux esophagitis (CRE) model. Rat CRE model was established operatively and then treated with BHSST (1 g/kg body weight per day) for 15 days Esophageal pathological changes were analyzed using macroscopic examination and hematoxylin/eosin staining. The antioxidant and inflammatory protein levels were determined using Western blotting. The administration of BHSST significantly reduced both the overexpression of serum reactive oxygen species (ROS) and an excessive formation of thiobarbituric acid-reactive substances (TBARS) in esophagus tissue. Thus, the severity of esophageal ulcer was lower in BHSST treated rats than control rats on the gross and histological evaluation. Nuclear factor-erythroid 2-related factor 2 (Nrf2) led to the upregulation of antioxidant enzyme including SOD, GPx-1/2, and HO-1 by binding to antioxidant response element (ARE). Moreover, BHSST administration markedly reduced the expression of inflammatory proteins through mitogen-activated protein kinase- (MAPK-) related signaling pathways and decreased significantly the protein expressions of inflammatory mediators and cytokines by inhibition of nuclear factor-kappa B (NF-κB) activation. Taken together, these results support the fact that BHSST administration can suppress the development of esophageal mucosal ulcer via regulating inflammation through the activation of the antioxidant pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nymphaea lotus, which is widely distributed throughout tropical Africa, enjoys a number of ethnomedical uses in Nigeria. Traditionally, the rhizomes of N. lotus are used to cure diarrhoea. AIM OF STUDY This study aims to evaluate the antidiarrhoeal activity of the methanol rhizome extract of N. lotus plant in laboratory animals. MATERIALS AND METHODS The extract was screened for activity against castor oil-induced diarrhoea and magnesium sulphate-induced diarrhoea as well as effect on gastric transit time in mice. The effect of methanol rhizome extract of Nymphaea lotus on the perfused isolated tissue preparation was also determined. RESULTS For castor oil-induced diarrhoea, the extract at doses of 200, 400 and 800mg/kg produced significant reduction in the frequency of diarrhoea (at p<0.001, p<0.001 and p<0.01 respectively). The extract at 800mg/kg produced a significant delay in onset of diarrhoea (p<0.05) comparable to loperamide (3mg/kg). The frequency of magnesium sulphate-induced diarrhoea was also significantly reduced in the groups treated with 200, 400 and 800mg/kg of the extract at p<0.001, p<0.001 and p<0.01 respectively. At doses of 200mg/kg and 400mg/kg, the protection produced was comparable to loperamide, 3mg/kg. All treated groups produced significant reduction in the transit of charcoal meal along the intestinal tract at p<0.001. The extract at low concentration (4×10(-4)-6.4×10(-2)mg/ml) had contractile effect on the tone of contraction of the rabbit jejunum while at higher concentrations (8×10(-2)-512×10(-2)mg/ml) produced significant reduction in the tone and rate of spontaneous contraction of rabbit jejunum. The extract at lower concentrations (4×10(-4)-2×10(-2)mg/ml) has no effect on contraction of the guinea pig ileum while higher concentrations (4×10(-2)-512×10(-2)mg/ml) produced significant relaxant activity on guinea pig ileum. CONCLUSION This study has shown that the methanol rhizome extract of N. lotus has antidiarrhoeal properties thus justifying its use by the local population for this purpose.

Abstract
Aim: The present study was conducted to evaluate the antidiarrheal effect of ethanolic extract of Holarrhena antidysenterica (Family - Apocynaceae) seeds against induced diarrhea in Wistar albino rats. Materials and Methods: The extract was evaluated for castor oil and Escherichia coli induced diarrhea. Extract was given at 100, 200, 400 mg/kg body wt. orally in both protocols. Standard antidiarrheal Loperamide was used at 5 mg/kg body wt. orally in castor oil induced protocol, while standard antibiotic Gentamicin at 8 mg/kg body wt. intraperitoneally was used in E. coli induced diarrhea. In castor oil induced protocol, the percentage inhibition of defecation was calculated for each group, whereas in E. coli induced protocol, change in fecal consistency, and body weight was recorded for each individual rat for 3 days. Results: The severity of castor oil induced diarrhea was reduced significantly (p<0.05) with H. antidysenterica seeds extract at 200 and 400 mg/kg body wt. which showed equivalent effectiveness like that of Loperamide treated groups. Similarly in E. coli induced diarrhea protocol, the mean change in body weight was significantly (p<0.05) higher in positive control, whereas no significant variation was observed in negative control, Gentamicin treated and H. antidysenterica treated group at 200 mg/kg and 400 mg/kg body wt., respectively. Conclusion: The study concluded that ethanolic extract of H. antidysenterica seeds effectively controlled diarrhea and decreased the severity of clinical signs of castor oil and E. coli induced diarrhea in Wistar rats.

Antidiarrheal activity of cashew GUM, a complex heteropolysaccharide extracted from exudate of Anacardium occidentale L. in rodents. JOURNAL OF ETHNOPHARMACOLOGY 2015; 174:299-307. [PMID: 26297843 DOI: 10.1016/j.jep.2015.08.020] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2015] [Revised: 07/18/2015] [Accepted: 08/18/2015] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anacardium occidentale L. (Anacardiaceae) is commonly known as the cashew tree. It is native to tropical America and extracts of the leaves, bark, roots, chestnut net and exudate have been traditionally used in northeast Brazil for the treatment of various diseases. The exudate of the cashew tree (cashew gum) has been exploited by locals since ancient times for multiple applications, including the treatment of diarrheal diseases. AIM OF THE STUDY The primary aim of the present study is to evaluate the antidiarrheal activity of cashew gum (CG), a complex heteropolysaccharide from the exudate of the cashew tree, using various models. MATERIALS AND METHODS The antidiarrheal activity of cashew gum (CG) against acute diarrhea was investigated using the castor oil-induced diarrhea model. The effects of CG on gastrointestinal transit and castor oil- and PGE2- induced enteropooling were also examined in rodents. In addition, the effect of CG against secretory diarrhea was investigated using a model of fluid secretion in cholera toxin-treated intestinal closed loops in live mice. RESULTS Cashew gum (30, 60, and 90 mg/kg, p.o.) showed a significant (P<0.05-0.01) antidiarrheal effect in rats with castor oil-induced diarrhea, inhibiting the total amount of stool and diarrheal stools. The 60 mg/kg dose of CG exhibited excellent antidiarrheal activity and significantly reduced the severity of diarrhea (diarrhea scores) in rats. CG (60 mg/kg) significantly (P<0.05) decreased the volume of castor oil- and PGE2-induced intestinal fluid secretion (enteropooling). In addition, similar to loperamide (standard drug, 5 mg/kg, p.o.), CG treatment reduced the distance traveled by a charcoal meal in the 30-min gastrointestinal transit model by interacting with opioid receptors. In cholera toxin-induced secretory diarrhea, CG (60 mg/kg) significantly inhibited the intestinal fluid secretion and decreased Cl(-) ion loss in the cholera toxin(-)treated isolated loops model of live mice by competitively binding to cholera toxin-GM1 receptors. CONCLUSIONS In conclusion, our results indicate that a complex heteropolysaccharide extracted from the exudate of A. occidentale L. has antidiarrheal activity in acute, inflammatory, and secretory diarrhea models, which could justify its traditional use in the treatment of diarrhea in northeast Brazil. The antidiarrheal activity might be explained by the capacity of CG to inhibit gastrointestinal motility and thereby reduce the accumulation of intestinal fluid and the secretion of water and chloride ions in the lumen of the intestine.

Abstract
A simple and accurate high-performance liquid chromatography-photodiode array (HPLC-PDA) detection method has been developed and validated for simultaneous determination of nine components-liquiritin, coptisine, baicalin, palmatine, berberine, wogonoside, baicalein, glycyrrhizin and wogonin-in the traditional Korean formula, Banhasasim-tang decoction. A Gemini C18 analytical column was used to separate the nine constituents and kept at 40°C by gradient elution with 0.1% (v/v) trifluoroacetic acid in distilled water (A) and acetonitrile (B) as mobile phases. The flow rate was 1.0 mL/min and the injection volume was 10 µL. The PDA detection wavelengths were set at 254, 275 and 350 nm. Calibration curves of all compounds showed good linearity with coefficients of determination ≥0.9998 within the test ranges. The limits of detection and quantification of all compounds were in the range 0.01-0.09 and 0.03-0.30 µg/mL, respectively. All recoveries of the nine marker compounds ranged from 98.65 to 103.22% with relative standard deviation (RSD) values <1.25%. The RSDs of intraday and interday precision were <1.13 and 1.83%, respectively. The concentrations of the nine marker constituents were 0.19-41.09 mg/g.

Abstract
One of the main factors able to explain the pathophysiological mechanism of inflammatory conditions that occur in periodontal disease is oxidative stress. Given the emerging understanding of this relationship, host-modulatory therapies using antioxidants could be interesting to prevent or slow the breakdown of soft and hard periodontal tissues. In this context, non-nutrient phenolic compounds of various foods and plants have received considerable attention in the last decade. Here, studies focusing on the relationship between different compounds of this type with periodontal disease have been collected. Among them, thymoquinone, coenzyme Q (CoQ), mangiferin, resveratrol, verbascoside and some flavonoids have shown to prevent or ameliorate periodontal tissues damage in animal models. However evidence regarding this effect in humans is poor and only limited to topical treatments with CoQ and catechins. Along with animal experiments, in vitro studies indicate that possible mechanisms by which these compounds might exert their protective effects include antioxidative properties, oxygen and nitrogen scavenging abilities, and also inhibitory effects on cell signaling cascades related to inflammatory processes which have an effect on RNS or ROS production as well as on antioxidant defense systems.

Abstract
OBJECTIVES The present study aimed to determine the efficacy of Hange-Shashin-To (HST), a Kampo medicine, in treating postoperative sore throat and nausea. DESIGN This randomized, controlled, double-blind study was conducted among two groups of adult female patients who were scheduled to undergo benign laparoscopic surgery under general anesthesia. All patients in each group had a physical status of either 1 (normal, healthy patient) or 2 (patient with a mild systemic disease), according to the American Society of Anesthesiologists. Patients were randomly assigned to either the HST group or the placebo (control) group. INTERVENTION Before surgery, the HST group received HST (5.0 g) mixed with jelly, while the placebo group received only jelly. Patients and the evaluator were blinded to the treatment status. OUTCOME MEASURES At 0, 3, and 24 hours after anesthesia recovery, an investigator (also blinded to the treatment status) recorded incidence and severity using the Numeric Rating Scale for sore throat and nausea. RESULTS Incidence and severity of sore throat were significantly lower in the HST group than in the control group immediately and 3 hours after surgery (p<0.05). In contrast, incidence and severity of nausea did not differ significantly between the HST and control groups. CONCLUSIONS HST administration before general anesthesia did not alleviate postoperative nausea, but effectively decreased the incidence and severity of postoperative sore throat in female patients undergoing laparoscopic surgery.

Abstract
With increasing use of herbal medicines for chronic or serious illness, relevant quality assurance methods are essential for making claims of therapeutic benefit. Adequate demonstration of safety and efficacy based on chemical composition and ensuring consistency between manufactured batches is critical. To date, there has been no uniform standard approach or detailed framework provided to industry for selecting relevant chemical markers used to standardize herbal products. We developed the Herbal Marker Ranking System (Herb MaRS) providing guidance on prioritizing the selection of chemical markers for quality control of complex multi-herb mixtures, while also taking into account the bioactivity in relation to the symptoms of the disease and its concentration in the formula. We apply the Herb MaRS evaluation criteria to a seven-herb formulation for the treatment of irritable bowel syndrome with constipation. Our ranking scale accommodates the clinical and pharmacological use of the formulation and its claimed indications.

Abstract
PURPOSE Severe oral and pharyngeal mucositis is one of the most critical toxicities known to lead to the discontinuation of chemoradiotherapy (CRT) for head and neck cancer (HNC). Hangeshashinto (TJ-14) is a Kampo medicine that relieves chemotherapy-induced oral mucositis. We investigated the effect of TJ-14 on mucositis, nutritional status, and the completion rate of CRT. METHODS The study group comprised patients with advanced HNC who were treated with concomitant weekly cisplatin and 70 Gy of radiotherapy. The primary endpoint was the completion rate of chemotherapy, and the secondary endpoints were the grade of mucositis and the nutritional status. RESULTS A total of 57 patients were included in this study. The completion rate of CRT among patients who were treated with TJ-14 was 91.4%. There was a significant difference in the completion rate of CRT between the groups treated with and without TJ-14 (p = 0.0452). The reduction in body weight was significantly improved from 10.89 to 5.89% with TJ-14 administration (p = 0.003), and the reduction in serum albumin was also significantly decreased from 17.37 to 8.73%. (p = 0.024). CONCLUSION This therapy allowed a high completion rate of CRT as well as significant benefits in terms of nutritional status. We plan to carry out a further large-scale study of TJ-14.

Traditional Herbal Formula Banhasasim-tang Exerts Anti-Inflammatory Effects in RAW 264.7 Macrophages and HaCaT Keratinocytes. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:728380. [PMID: 25838833 PMCID: PMC4369961 DOI: 10.1155/2015/728380] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2014] [Revised: 02/16/2015] [Accepted: 02/24/2015] [Indexed: 12/13/2022]
Abstract
Banhasasim-tang (BHSST) is a Korean traditional herbal formula comprising eight medicinal herbs. The aim of the present study was to investigate the anti-inflammatory effect of BHSST using macrophage and keratinocyte cell lines. First, we evaluated the effects of BHSST on inflammatory mediator and cytokine production in lipopolysaccharide- (LPS-) stimulated RAW 264.7 macrophages. BHSST markedly inhibited the production of nitric oxide (NO), prostaglandin E2 (PGE2), and interleukin- (IL-) 6. BHSST significantly suppressed the protein expression of toll-like receptor 4 (TLR4) and phosphorylated nuclear factor-kappa B (NF-κB) p65 in RAW 264.7 cells. Second, we examined whether BHSST influences the production of chemokines and STAT1 phosphorylation in tumor necrosis factor-α/interferon-γ TI-stimulated HaCaT keratinocytes. BHSST significantly suppressed the production of RANTES/CCL5, TARC/CCL17, MDC/CCL22, and IL-8 in TI-stimulated HaCaT cells. BHSST also suppressed TI-induced phosphorylation of STAT1 in HaCaT cells. These results suggest that BHSST may be useful as an anti-inflammatory agent, especially for inflammatory skin diseases.

Abstract
AIM The roots of Potentilla fulgens Wall. ex Hook. (Rosaceae) have been used in the indigenous system of medicine in Northeast India to treat diarrhea. The aim of this study was to investigate the safety and protective effects of P. fulgens root extract in experimentally induced diarrhea in mice. MATERIALS AND METHODS The protective effects of P. fulgens root extract was investigated against experimentally induced diarrhea in mice, using four experimental models, that is the measurement of fecal output, castor oil model, prostaglandin E2 (PGE2) enteropooling assay, and gastrointestinal transit test. The safety assessment of root extract was done in mice on the basis of general signs and symptoms of toxicity, food water intake and mortality of animals following their treatment with various doses of extract (100-3200 mg/kg). In addition, the serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, cholesterol and total protein of experimental mice were also monitored to assess the toxicity of root extract. RESULTS In the safety assessment studies, P. fulgens root extract did not showed any visible signs of toxicity, but mortality was observed in a single animal at 3200 mg/kg dose of extract. The extract also did not showed any adverse effects on the studied serum parameters of experimental animals. In the antidiarrheal tests, administration of 800 mg/kg dose of extract to mice showed 50% protection from diarrhea evoked by castor oil. In addition, the extract also showed 29.27% reduction in PGE2-induced intestinal secretion as compared with 30.31% recorded for loperamide, a standard antidiarrheal drug. CONCLUSIONS The results of this study indicate that P. fulgens root extract possesses significant antidiarrheal properties. Therefore, the roots of this plant can be an effective traditional medicine for protection from diarrhea.

Abstract
BACKGROUND Hangeshashinto (TJ-14, a Kampo medicine), which reduces the level of prostaglandin E2 and affects the cyclooxygenase activity, alleviates chemotherapy-induced oral mucositis (COM). We conducted a randomized comparative trial to investigate whether TJ-14 prevents and controls COM in patients with gastric cancer. METHODS We randomly assigned patients with gastric cancer who developed moderate-to-severe oral mucositis (CTCAE v4.0 grade ≧1) during any cycle of chemotherapy to receive either TJ-14 or a placebo as a double-blind trial. The patients received a placebo or TJ-14 for 2-6 weeks according to the chemotherapy regimen from the beginning of the next course of chemotherapy. The primary end point was the incidence of grade ≧2 oral mucositis in the protocol treatment course, and the secondary end points were the time to disappearance of oral mucositis and the incidence of adverse events. RESULTS Following the key opening of the blinding protocol, we analyzed 91 eligible patients (TJ-14: 45, placebo: 46) using a "per protocol set" analysis. The incidence of ≧grade 2 COM was 40.0 % in the TJ-14 group and 41.3 % in the placebo group (p = 0.588). The median duration of ≧grade 2 COM was 14 days in the TJ-14 group and 16 days in the placebo group (p = 0.894). Meanwhile, the median duration of any grade of COM was 9 days in the TJ-14 group and 17 days in the placebo group among the patients who developed grade 1 symptoms during the screening cycle [hazard ratio 0.60; 95 % CI (0.23-1.59), p = 0.290]. CONCLUSIONS Although TJ-14 treatment did not reduce the incidence of ≥2 COM in the patients who developed mucositis during chemotherapy for gastric cancer, a trend was observed in which TJ-14 reduced the risk of COM in the patients who developed grade 1 COM during the screening cycle. Further, phase III studies with a larger sample size are needed to clarify the protective effects of TJ-14 for COM.

Abstract
Objective. Chemotherapy-induced oral mucositis (COM) is characterized by painful inflammation with prolonged damage that involves the pathological pain-evoking prostaglandin E2 (PGE2). We previously found that gargling with hangeshashinto (HST), a traditional Japanese medicine, was effective for the treatment of COM. However, little is known regarding the mechanisms. Our aim was to identify the active ingredients and clarify the characteristic effects of HST on the PGE2 system. Methods. Prostanoids produced by human oral keratinocytes (HOK) stimulated with IL-1β were measured by enzyme immunoassay. Active ingredients that regulate PGE2 production were identified and quantified by liquid chromatography–tandem mass spectrometry (LC-MS/MS) and a culture system of HOK cells. Results. Inducible PGE2, PGD2, and PGF2α, metabolites of cyclooxygenase (COX) pathways, were reduced by HST (10-300 µg/mL) without inducing cytotoxicity. The active ingredients of HST were quantified by LC-MS/MS, and [6]-shogaol, [6]-gingerol, wogonin, baicalein, baicalin, and berberine were shown to reduce PGE2 production. A mixture of these 6 ingredients at concentrations equal to 300 µg/mL of HST strongly suppressed PGE2 production to the same level as HST. [6]-Shogaol and [6]-gingerol did not decrease COX-2 mRNA expression and mostly inhibited PGE2 metabolic activity in an assay using intact HOK cells, suggesting that they regulate PGE2 synthesis at the posttranscriptional level. Wogonin, baicalin, and berberine inhibited expression of COX-2 mRNA without affecting PGE2 metabolic activity. Moreover, wogonin, but not [6]-shogaol, suppressed phosphorylation of mitogen-activated protein kinases (p38s and JNKs). Conclusions. These lines show that HST includes several PGE2-regulating ingredients that have different mechanisms and can function as a multicomponent and multitarget agent for treatment of COM, indicating that HST may be beneficial in a new medical strategy for COM treatment.

Abstract
OBJECTIVE To evaluate the pharmacological activity against diarrhea of methanol and petroleum ether extract of Desmodium puchellum (Family: Fabaceae) leaves. METHODS The extract was evaluated for castor oil-induced diarrhea and enteropooling as well as intestinal motility in rats. Both of the extracts were given to the rats at 200 mg/kg orally. Loperamide was used as a standard drug for diarrhea. RESULTS The diarrheal severity was reduced significantly (P<0.05) by methanol and petroleum ether extracts by 31.95% and 28.33%, respectively, whereas 54.75% inhibition was found for standard drug loperamide at 5 mg/kg. The two extracts also significantly (P<0.05) reduced the intestinal volume in case of castor oil induced enteropooling. CONCLUSIONS It is concluded that both fractions contain some biologically active ingredients that are active for anti-diarrheal actions whereas methanol fraction has better potential.

Abstract
Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Abstract
Treatment with kampo, the Japanese traditional medicine, is a form of pharmacological therapy that combines modern Western and traditional Asian medical practices. In Japan, various traditional medicines are often combined with Western medicines and prescribed for patients with diseases such as gastroesophageal reflux disease, functional dyspepsia, chronic gastritis, irritable bowel syndrome, and post-operative ileus. Based on numerous past observations, Japanese traditional medicines are thought to be particularly useful in the treatment of medically unexplained physical symptoms such as nausea, abdominal discomfort, and anorexia. However, the detailed mechanism by which they mediate their pharmacological action is yet unknown. In addition, the clinical evidence to support their use is insufficient. This review focuses on the basic evidence of the pharmacological action and the clinical efficacies of kampo medicines accumulated over several past decades. In addition, we introduce both the current novel insights into kampo medicines and the therapeutic approach employed when they are used to treat various disorders of the gastrointestinal tract.

Abstract
The Japanese Kampo medicines Hange-shashin-to (TJ-14) and Keishi-ka-shakuyaku-to (TJ-60) have been used to treat symptoms of human diarrhea on an empirical basis as Japanese traditional medicines. However, it remains unclear how these drugs affect smooth muscle tissues in the distal colon. The aim of the present study was to investigate the effects of TJ-14 and TJ-60 on the contractile activity of circular smooth muscle from the rat distal colon. TJ-14 and TJ-60 (both 1 mg/ml) inhibited spontaneous contractions of circumferentially cut preparations with the mucosa intact. Blockade of nitric oxide (NO) synthase or soluble guanylate cyclase activity abolished the inhibitory effects of TJ-60 but only attenuated the inhibitory effects of TJ-14. Apamin (1 μM), a blocker of small-conductance Ca(2+)-activated K(+) channels (SK channels), attenuated the inhibitory effects of 5 mg/ml TJ-60 but not those of 5 mg/ml TJ-14. TJ-14 suppressed contractile responses (phasic contractions and off-contractions) evoked by transmural nerve stimulation and increased basal tone, whereas TJ-60 had little effect on these parameters. These results suggest that 1 mg/ml TJ-14 or TJ-60 likely inhibits spontaneous contractions of the rat distal colon through the production of NO. Activation of SK channels seems to be involved in the inhibitory effects of 5 mg/ml TJ-60. Since TJ-14 has potent inhibitory effects on myogenic and neurogenic contractile activity, TJ-14 may be useful in suppressing gastrointestinal motility.

Abstract
BACKGROUND Huang-Lian-Jie-Du-Tang (HLJDT), a famous traditional Chinese prescription with wide anti-inflammatory applications, is an aqueous extract of four herbal materials: Rhizoma coptidis, Radix scutellariae, Cortex phellodendri, and Fructus gardeniae. Its effects on the cyclooxygenase (COX)-2 and 5-lipoxygenase (5-LOX) pathways are thought to be responsible for its anti-inflammatory activity. However, our previous work found that the inhibitory effects of HLJDT act on the 5-LOX pathway but not on the COX pathway. The possibility that HLJDT inhibits COX-2- or 5-LOX-catalyzed eicosanoid generation by downregulating enzyme expression requires further investigation. AIM OF THE STUDY To observe the effects of HLJDT and its four major components (baicalin, baicalein, berberine and geniposide) on COX-2- or 5-LOX-catalyzed eicosanoid generation and to distinguish the effects of HLJDT on enzyme activity from those on enzyme expression. METHODS The topical anti-inflammatory activities and inhibition of eicosanoid formation of HLJDT and its components were observed in an arachidonic acid (AA)-induced mouse ear edema model. Macrophage-based systems were established to observe the effects of the drugs on enzyme activity and enzyme expression of COX-2 and 5-LOX. Further experiments were carried out to confirm these effects at the mRNA and protein levels. RESULTS Topical treatment of HLJDT significantly inhibited AA-induced mouse ear edema and reduced PGE(2) and LTB(4) release in the edematous ears. Baicalein, geniposide, and berberine also ameliorated the symptoms and suppressed eicosanoid generation with varying efficacies. Cell-based assays showed that HLJDT and baicalein inhibited the PGE(2) levels by decreasing COX-2 enzyme expression without affecting COX-2 enzyme activity in RAW 246.7 murine macrophages. The other experiments on rat peritoneal macrophages indicated that HLJDT and baicalein exerted significant inhibition on LTB(4) production by decreasing 5-LOX enzyme activity. The real-time PCR and western blotting data demonstrated that HLJDT and baicalein reduced COX-2 expression at the mRNA and protein levels, whereas no inhibition on 5-LOX expression was observed. CONCLUSIONS HLJDT can suppress eicosanoid generation via both the COX and LOX pathways, which definitely contributes to its topical anti-inflammatory activity. We have confirmed that its dual inhibition on the COX and LOX pathways mainly result from the downregulation of COX-2 expression and direct inhibition of 5-LOX activity, respectively. Baicalein worked as a potent active component in most of the tests. These findings about the different inhibitory effects of HLJDT on COX-2 and 5-LOX help to better understand the mechanism of HLJDT and promote safer applications of drug.

Abstract
AIM OF THE STUDY Huang-Lian-Jie-Du-Tang (HLJDT) is a traditional Chinese medicine with anti-inflammatory use. In the present study, the effects of its component herbs and pure components were observed on eicosanoid generation to find out the contributory components and their precise targets on arachidonic acid (AA) cascade. MATERIALS AND METHODS By monitoring leukotriene B(4) (LTB(4)), 5-hydroxyeicosatetraenoic acid (5-HETE), and 12-hydroxy-5,8,10-heptadecatrienoic acid (12-HHT), we compared the effects of HLJDT, HLJDT free of one or two component herbs, and water extract of four single component herbs of HLJDT (Rhizoma coptidis, Radix scutellariae, Cortex phellodendri and Fructus gardeniae) on eicosanoid generation in rat elicited peritoneal macrophages. In addition, thirteen pure compounds from HLJDT (baicalin, baicalein, wogonoside, wogonin, berberine, magnoflorine, phellodendrine, coptisine, palmatine, jateorrhizine, crocin, chlorogenic acid, and geniposide) were tested in the macrophages. Furthermore, the efficacies of these thirteen compounds were evaluated on cell-free purified enzymes: leukotriene A(4) hydrolase (LTA(4)H), 5-, 15-lipoxygenase (5-, 15-LO), and cyclo-oxygenase-1/2 (COX-1/2). Moreover, the possible synergetic effect on LO pathway derived LTB(4) generation between the active components was also tested in rat peritoneal macrophages. RESULTS Our experiments showed that Rhizoma coptidis and Radix scutellariae were responsible for the suppressive effect of HLJDT on eicosanoid generation. Some of the pure components including baicalein, baicalin, wogonoside, wogonin, coptisine, and magnoflorine inhibited eicosanoid generation in rat macrophages via LO pathway of AA cascade. Further experiments on cell-free purified enzymes confirmed that Radix scutellariae derived baicalein and baicalin showed significant inhibition on 5-LO and 15-LO, while Rhizoma coptidis derived coptisine showed medium inhibition on LTA(4)H. On the other hand, no significant inhibition of thirteen components on COX-1/2 was observed. Moreover, the slight synergetic inhibition on LTB(4) between baicalein and coptisine was proved in the rat peritoneal macrophages. CONCLUSIONS Baicalein and coptisine, the active components of HLJDT, for the first time are found to interfere with arachidonic acid cascade via inhibition on different points of LO pathway. This finding makes the mechanism of HLJDT clearer and achieves its safer therapeutic application.

Abstract
BACKGROUND Functional dyspepsia (FD) is characterized by a high prevalence rate and no standard conventional treatments. Alternative therapies, such as herbal formulas, are widely used to treat FD. However, there are inadequate evidences regarding the safety and efficacy of these formulas. Moreover, the mechanisms by which herbal formulas act in the gastrointestinal tract are controversial. In traditional Korean medicine, Banha-sasim-tang has long been one of the most frequently prescribed herbal formulas for treating dyspepsia. The current study is designed to evaluate the efficacy and safety of Banha-sasim-tang for FD patients and to examine whether there will be a significant correlation between cutaneous electrogastrography recordings and dyspeptic symptoms in FD patients, and between changes in gastric myoelectrical activity and improvement in dyspeptic symptoms during Banha-sasim-tang administration. METHODS This randomized, double-blind, placebo-controlled trial will be performed at two centers and will include a Banha-sasim-tang group and placebo group. Each group will consist of 50 FD patients. Six weeks of administration of Banha-sasim-tang or placebo will be conducted. During the subsequent 2 months, follow-up observations of primary and secondary outcomes will be performed. The primary outcomes are differences as measured on the gastrointestinal symptom scale, and the secondary outcomes are differences as measured on the visual analogue scale for dyspepsia and on the questionnaire for FD-related quality of life. All outcomes will be measured at baseline, at 2, 4, and 6 weeks of treatment, and at the 1 and 2 month follow-up. Cutaneous electrogastrography will be performed and assessed at baseline and at 6 weeks. DISCUSSION This trial will provide evidence of the safety and efficacy of Banha-sasim-tang for the treatment for FD. Furthermore, based on the assessment of the relationship between cutaneous electrogastrography recordings and dyspeptic symptoms in this trial, the possibility of clinical applications of cutaneous electrogastrography in the treatment of FD will be elucidated.

Inhibition of inducible nitric oxide production and iNOS protein expression in lipopolysaccharide-stimulated rat aorta and Raw 264.7 macrophages by ethanol extract of a Chinese herbal medicine formula (RCM-101) for allergic rhinitis. JOURNAL OF ETHNOPHARMACOLOGY 2008; 116:547-553. [PMID: 18291608 DOI: 10.1016/j.jep.2008.01.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/03/2007] [Revised: 12/08/2007] [Accepted: 01/07/2008] [Indexed: 05/25/2023]
Abstract
AIM OF THE STUDY A Chinese herbal formula (RCM-101) has shown to be effective in reducing symptoms of seasonal allergic rhinitis (SAR) in a randomised, placebo-controlled clinical trial. The aim of this study is to investigate the effects of RCM-101 on the actions and synthesis of nitric oxide (NO). l-Arginine-induced endothelium-independent relaxations were studied in rat isolated aorta which was pre-treated with lipopolysaccharide (LPS). MATERIALS AND METHODS NO production and inducible nitric oxide synthase (iNOS) protein expression were studied in LPS and interferon gamma-stimulated murine macrophages (Raw 264.7), measured by NO sensors and Western blotting. RESULTS In rat aortic preparations, RCM-101 significantly inhibited endothelium-independent relaxations to l-arginine, but not affected those to sodium nitroprusside (SNP). In Raw 264.7 cells, RCM-101 and some of its individual ingredients (e.g., Radix glycyrrhizae, Radix bupleuri, Radix saposhnikoviae and Atractylodis rhizome macrocephalae) significantly inhibited the NO production and iNOS protein expression. CONCLUSIONS The findings indicate that RCM-101 may inhibit inducible NO production by suppressing iNOS. In addition, its inhibitory action of iNOS is likely to be mediated by several key herbal ingredients.

Abstract
Emilia coccinea (Sims) G. Don is reported to possess a number of medicinal properties including antidiarrhoeal and antimicrobial activities. The antidiarrhoeal effects of both methanol and aqueous extracts of the leaves of Emilia coccinea were studied in rats against castor oil-induced diarrhoea at the doses of 200, 400 and 600 mg/kg body weight. The methanol extract, and to a lesser extent the aqueous extract, significantly prolonged the time for diarrhoeal induction; it reduced the frequency of diarrhoea episodes and decreased the propulsion of charcoal meal through the gastrointestinal tract in a dose dependent manner. The aqueous extract did not have any antimicrobial activity at the tested concentration (5 mg/ml), but the methanol extract was most active on Escherichia coli. These results may support the fact that this plant is used traditionally to cure diarrhoea.

Abstract
Herbal therapies are being used increasingly for the treatment of allergic rhinitis. The aim of this study was to investigate the possible pharmacological actions and cellular targets of a Chinese herbal formula (RCM-101), which was previously shown to be effective in reducing seasonal allergic rhinitis symptoms in a randomized, placebo-controlled clinical trial. Rat and guinea pig isolated tissues (trachea and aorta) were used to study the effects of RCM-101 on responses to various mediators. Production of leukotriene B4 in porcine neutrophils and of prostaglandin E2 and nitric oxide (NO) in Raw 264.7 cells were also measured. In rat and guinea pig tracheal preparations, RCM-101 inhibited contractile responses to compound 48/80 but not those to histamine (guinea pig preparations) or serotonin (rat preparations). Contractile responses of guinea pig tracheal preparations to carbachol and leukotriene C4, and relaxant responses to substance P and prostaglandin E2 were not affected by RCM-101. In rat aortic preparations, precontracted with phenylephrine, endothelium-dependent relaxant responses to acetylcholine and endothelium-independent relaxant responses to sodium nitroprusside were not affected by RCM-101. However, RCM-101 inhibited relaxations to l-arginine in endothelium-denuded rat aortic preparations, which had been pre-incubated with lipopolysaccharide. RCM-101 did not affect leukotriene B4 formation in isolated porcine neutrophils, induced by the calcium ionophore A23187; however, it inhibited prostaglandin E2 and NO production in lipopolysaccharide-stimulated murine macrophages (Raw 264.7 cells).The findings indicate that RCM-101 may have multiple inhibitory actions on the release and/or synthesis of inflammatory mediators involved in allergic rhinitis.

Abstract
Acceleration of vascular smooth muscle cell (VSMC) proliferation is closely linked to the pathogenesis of vascular diseases. We, therefore, focused on traditional Japanese herbal medicines (Kampo medicines) used to ameliorate the impairment of microcirculation or blood stasis and screened them for their ability to inhibit rat VSMC proliferation. Among them, Unsei-in was found to effectively suppress VSMC proliferation, and Coptis rhizome was the responsible constituent crude drug. The extract of Coptis rhizome inhibited VSMC proliferation with the GI(50) value of 4.4 microg/ml, which was much lower than those against the proliferation of 3Y1, dRLh-84, B16, and HeLa cells. The Coptis rhizome extract inhibited the progression of VSMC arrested at G(0)/G(1) phase from G(0)/G(1) to S phase, but not that of 3Y1 cells. Biological assay-guided fractionation revealed that an alkaloid of Coptis rhizome, coptisine, was the active ingredient in selectively preventing VSMC proliferation with GI(50) of 3.3 microM (1.2 microg/ml). When the structurally-related isoquinoline alkaloids of protoberberine class were studied for their inhibitory activities, berberine decreased the VSMC proliferation with GI(50) of 95.1 microM (35.4 microg/ml), about 30 times higher concentration than coptisine, while palmatine failed to show any activity. This study provides evidence that coptisine, an ingredient of Unsei-in, prevents VSMC proliferation selectively at lower concentrations compared with various cells or other structurally related alkaloids.

Abstract
Hange-shashin-to (HST) has been used as an herbal formula to treat inflammatory ulcerative gut diseases complicated with psychoneurosis in Japanese traditional Kampo medicine. The aim of the present study is to clarify anti-colitic effect of HST using a model of colitis induced by intracolonic instillation of 2,4,6-trinitrobenzene sulfonic acid (TNBS) in rats, and to evaluate the pharmaceutical properties of its herbal components. The colonic damage was elucidated by macroscopic damage scores, colon wet weight and area of mucosal necrosis. Orally administered HST significantly reduced the colonic damage. Other rats were orally treated with single-component berberine (BE), baicalin (BA), glycyrrhizin (GL) or saponin fraction of ginsenosides (GS), or with the mixture (TL) of BA, BE, GL and GS, or with the combinations of BA plus BE (BA-BE), or that of GL plus GS (GL-GS). Oral treatment of TL ameliorated colitis observations. However, no effects were found in the treatment of single-component BA, BE, GL or GS, whereas the GL-GS combination ameliorated the colitis. These results suggest that HST might suppress inflammatory bowel disease (IBD) and imply that there will be a potential benefit in the traditionally derived herbal combination.

Abstract
In the present study, we performed to selectively deplete glycyrrhizin from Si-Ni-San, a traditional Chinese prescription that consists of 4 Chinese herbs including Radix Glycyrrhizae Uralensis, and examined its influence on the suppressing activity of Si-Ni-San against contact sensitivity in mice. An immunoaffinity column was made by covalently coupling the polyclonal antibody, obtained by the immunization with glycyrrhizin–BSA conjugate, to CNBr-activated Sepharose 4B. By using this column, glycyrrhizin in Si-Ni-San was selectively and almost completely depleted from the whole extract, which was confirmed by high-performance liquid chromatography (HPLC). Both 200 mg/kg of Si-Ni-San and 10 mg/kg of glycyrrhizin, the dose corresponding to its proportion contained in Si-Ni-San, significantly reduced the ear swelling of picryl chloride (PCl)-induced ear contact sensitivity in mice and the inhibition by Si-Ni-San was stronger than that by glycyrrhizin. The adhesion activity to type IV collagen of the isolated spleen cells from PCl-sensitized mice was significantly decreased by both Si-Ni-San and glycyrrhizin. However, the glycyrrhizin-depleted sample of Si-Ni-San (Si-Ni-SanGL−) only showed a slight inhibition on the cell adhesion. Furthermore, the spleen cells from PCl-sensitized mice produced more matrix metalloproteinase (MMP)-2 and -9 than naive spleen cells did, and both Si-Ni-San and glycyrrhizin remarkably reduced MMP-2 and MMP-9 production. In contrast, Si-Ni-SanGL− only showed a slight inhibition. These results suggest that glycyrrhizin may act as one of the active constituents of Si-Ni-San in inhibiting delayed-type hypersensitivity reaction via down-regulating the MMP production and the cell adhesion to extracellular matrix. The present study also provides a new approach to recognize and validate an active constituent in traditional prescription through a selective depletion.

Abstract
UNLABELLED We tested baicalin for its antiinflammatory and analgesic effects (and the mechanisms) in a rat model of carrageenan-evoked thermal hyperalgesia. Pre- or posttreatment with baicalin (10, 30, or 100 mg/kg intraperitoneally) caused a significant analgesic effect with a similar effect of dose-matched ibuprofen. Furthermore, baicalin dose-dependently attenuated tumor necrosis factor-alpha (from 3510 +/- 150 pg/mL to 2860 +/- 148 pg/mL to 1480 +/- 210 pg/mL), interleukin (IL)-1beta (from 3210 +/- 210 pg/mL to 2200 +/- 140 pg/mL to 750 +/- 95 pg/mL), and IL-6 (from 58.5 +/- 9.8 pg/mL to 38.5 +/- 9.0 to 21.0 +/- 8.1 ng/mL) formation but enhanced IL-10 (from 18.1 +/- 2.5 pg/mL to 36.1 +/- 5.5 pg/mL to 71.2 +/- 9.5 pg/mL) production in paw exudates at 4 h after carrageenan injection. Prostaglandin E(2) (PGE(2)) and nitrate formation in the carrageenan-injected paws were dose-dependently inhibited by baicalin (10-100 mg/kg intraperitoneally) (PGE(2): from 15.9 +/- 2.1 ng/mL to 12.1 +/- 1.6 ng/mL to 6.2 +/- 1.8 ng/mL; nitrate: from 39.8 +/- 4.8 microM to 27.5 +/- 3.0 microM to 17.2 +/- 1.6 microM) at 4 h but not at 1.5 h after carrageenan injection. Increased myeloperoxidase activity in carrageenan-injected paws was also dose-dependently reduced by baicalin. These findings suggest that the antiinflammatory and analgesic mechanisms of baicalin may be associated with the inhibition of critical inflammatory mediators, including nitric oxide, PGE(2), and proinflammatory cytokines, accompanied by an increase in IL-10 production, as well as neutrophil infiltration at sites of inflammation. IMPLICATIONS Our results showed that baicalin possesses an analgesic effect in carrageenan-evoked thermal hyperalgesia. The possible mechanisms of action of baicalin may be associated with the inhibition of proinflammatory mediator overproduction, including cytokines, nitric oxide, and prostaglandin E(2), as well as neutrophil infiltration. This implies that baicalin may be a potential therapeutic analgesic for inflammatory pain.

Abstract
Endothelial cell apoptosis has been postulated as the initial trigger of the progression of microvascular disease in patients with diabetes mellitus. To investigate the role of Scutellariae radix extract, we examined its effect on the endothelial cell proliferation using the [3H]-thymidine incorporation method. Scutellariae radix extract significantly stimulated endothelial cell proliferation in a dose-dependent manner. We focused on the protective action of Scutellariae radix extract on the endothelial cell apoptosis induced by high glucose concentrations. Determination of endothelial cell apoptosis was performed using DNA gel electrophoresis, terminal deoxynuclotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay, and an ELISA kit. Exposure of vascular endothelial cell to high glucose (16.7 mM) for 72 h resulted in a significant increase in apoptosis, compared with the normal glucose concentrations (5.5 mM). Scutellariae radix extract inhibited high glucose-induced endothelial cell apoptosis. This result suggests that Scutellariae radix extract may contribute to antiapoptotic action against vascular endothelial cells, resulting in a beneficial effect in preventing diabetes-associated microvascular complications.

Abstract
Zingiberis Rhizoma (Shokyo, [Japanese characters: see text]) showed significant ameliorative effect on the BaCl2-induced delay of gastric emptying in rat. Bioassay-guided fractionation of the aqueous extract of Shokyo resulted in isolation of 6-gingesulfonic acid (1) and shogasulfonic acid A (3). These compounds significantly improved the delay of gastric emptying on both BaCl2-induced and N(G)-nitro-L-arginine (L-NNA)-induced model in rat. Zingiberis Siccatum Rhizoma (Kankyo, [Japanese characters: see text]) had significant efficacy against castor oil-induced diarrhea. In addition, Kankyo showed the activity increasing intestinal blood flow in normal rat.
