In vitro anti-coxsackievirus B(3) effect of ethyl acetate extract of Tian-hua-fen

AIM: To investigation the anti-coxsackievirus B(3) (CVB(3m)) effect of the ethyl acetate extract of Tian-hua-fen on HeLa cells infected with CVB(3m). METHODS: HeLa cells were infected with CVB(3m) and the cytopathic effects (CPE) were observed through light microscope and crystal violet staining on 96-well plate and A(600) was detected using spectrophotometer. The protective effect of the extract to HeLa cells and the mechanism of the effect were also evaluated through the change of CPE and value of A(600). RESULTS: The extract had some toxicity to HeLa cells at a higher concentration while had a marked inhibitory effect on cell pathological changes at a lower concentration. Consistent results were got through these two methods. We also investigated the mechanism of its anti-CVB(3m) effect and the results indicated that the extract represented an inhibitory effect through all the processes of CVB(3m) attachment, entry, biosynthesis and assemble in cells. CONCLUSION: The results demonstrate that the ethyl acetate extract of Tian-hua-fen has a significant protective effect on HeLa cells infected with CVB(3m) in a dose-dependent manner and this effect exists through the process of CVB(3m) attachment, entry, biosynthesis and assemble in cells, suggesting that the ethyl acetate extract of Tian-hua-fen can be developed as an anti-virus agent.

Role of oxidative stress in lansoprazole-mediated gastric and hepatic protection in Wistar rats.

BACKGROUND AND AIM: Lansoprazole, a benzimidazole derivative, is a widely-used proton-pump inhibitor. In addition, it has been reported to have an independent gastroprotective action. Since free radicals and antioxidant mechanisms appear to counter-act tissue-related injury, we studied the effect of lansoprazole on oxidative stress in acid-ethanol gastric injury. As this drug is metabolized in the liver, we also studied its effect on the liver. METHODS: Wistar rats were divided into three groups: control group, group I (vehicle treatment) and group II (lansoprazole treatment for eight days). In all the groups, injury was induced by ethanol-HCl administration. The effect of lansoprazole on free-radical generation and various antioxidants, e.g. superoxide dismutase (SOD), catalase, reduced glutathione (GSH), glutathione-s-transferase (GST) and glutathione reductase was evaluated in the gastric mucosal and liver homogenates. RESULTS: Ethanol-HCl administration initiated injury as shown by increase in malondialdehyde (MDA) levels in both gastric mucosa and liver. There was an increase in SOD and GST activity and a decrease in catalase, glutathione reductase and GSH in the gastric mucosa. In liver, ethanol-HCl administration decreased the activity of SOD, catalase and GSH and increased GST activity. Lansoprazole pretreatment led to decrease in the levels of MDA and increase in SOD, catalase, GSH, glutathione reductase and GST in both the gastric mucosa and liver. CONCLUSIONS: Lansoprazole has a protective action on gastric mucosa and the liver. This protection is mediated by a decrease in oxidative stress and a concomitant in-crease in antioxidants.     

Anti-arthritis activity of roots of Hemidesmus indicus R.Br. (Anantmul) in rats

ObjectiveTo investigate the protective effects of hydroalcoholic and its fractions from roots of Hemidesmus indicus on arthritis in in vitro models of rodents.MethodsPreliminary phytochemical analysis and thin-layer chromoatography were performed to analyze constituents of hydroalcoholic extract and its three fraction namely ethyl acetate fraction, chloroform fraction and residual fraction of root of Hemidesmus indicus. Arthritis rats models were established by Complete Freund's Adjuvant. The parameters including paw edema, body weight, arthritic index, erythrocyte sedimentation rate, serum rheumatoid factor, serum C-reactive protein, serum nitrite level, and histopathology of synovial joints were observed. Methotrexate was taken as positive control.ResultsRats treated with hydroalcoholic extract (450 mg/kg, p.o.), ethyl acetate (75 mg/kg, p.o.), chloroform (60 mg/kg, p.o) and residual fractions (270 mg/kg, p.o.), showed significant decrease in physical and biochemical parameters compared with arthritic model rats. Hydroalcoholic extract and its ethyl acetate fraction of Hemidesmus indicus showed significantly higher anti-arthritic activity than chloroform and residual fraction. Histopathological analysis demonstrated that both of hydroalcoholic extract and its ethyl acetate fraction had comparable anti-arthritic activity with methotrexates.ConclusionsThe present study suggests that Hemidesmus indicus has protective activity against arthritis and the activity might be attributed to presence of terpenoid in hydroalcoholic extract, as well as in ethyl acetate fraction.     

Protective effects of the whisky congeners on ethanol-induced gastric mucosal damage

BACKGROUND: The ingestion of both ethanol and whisky can induce acute gastrointestinal bleeding. The effects of the congeners, substances other than ethanol in whisky, on the ethanol-induced gastric mucosal damage were examined in the rat model. METHODS: After the whisky congeners were intragastrically administered previous to or simultaneous with ethanol ingestion, the gastric damage was macroscopically and microscopically measured. RESULTS: The simultaneous administration of the whisky congeners at a dose of 5 mg/kg body weight, which corresponds to the concentration of congeners contained in whisky, with 50% ethanol did not inhibit the hemorrhagic lesions, but inhibited them at a dose of 150 mg/kg. The treatment with the whisky congeners 30 minutes before the ethanol ingestion prevented the ethanol-induced gastric damage in a dose-dependent manner at 0.5 to 150 mg/kg. The butanol extract of the congeners revealed the strongest prevention compared with the ethyl acetate extract or the water fraction. The administration of indomethacin 60 minutes before the congener treatment partly inhibited the protective effects of the congeners, indicating the partial contribution of prostaglandins in this mechanism. The congeners did not prevent the mucosa by action as a "mild irritant" because the immunohistochemical studies using the antimucin monoclonal antibodies showed that no damage was induced by the administration of the congeners. CONCLUSION: The present results showed that the whisky congeners have a protective activity against ethanol-induced gastric mucosal injury.     

Hepatoprotective activity of Spillanthes acmella Extracts against CCl4-induced liver toxicity in rats

ObjectiveHepato protective activity of Spillanthes acmella Extracts (70% ethanol, methanol, ethyl acetate and hexane) were investigated.MethodsHepatoprotective activity was assessed against CCl4 induced liver intoxication.ResultsThe extracts were produced concentration dependent percentage protection in the reduction of enzymes (Serum Glutamate Oxaloacetate Transaminase, Serum Glutamate Pyruvate Transaminase, Alkaline phasphatase and Total bilirubin) levels against CCl4 induced liver intoxication in rats. Among all extracts methanol extract showed better activity compare to other extracts with percentage protection of SGOT (84.39%), SGPT (79.04%), ALP (78.15%) and Total bilirubin (80.00%) levels at a dose of 500mg/kg.ConclusionsFrom the results obtained during the present study it could be concluded that Spillanthes acmella extracts has components that have hepato protective effects.     

Effects of salviainolic acid A (SA-A) on liver injury: SA-A action on hepatic peroxidation

BACKGROUND/AIMS: This study aimed to investigate the actions of salviainolic acid A (SA-A), an antiperoxidative component of Salvia miltiorrhiza (Sm), on rat liver injury and fibrosis. METHODS: Acute and chronic rat liver injury models were established using carbon tetrachloride (CCl4). After 48 h (acute) or during 6 weeks of CCl4 injection, rats were further divided and treated with biphenyl dimethyl-dicarboxylate (BDD) or colchicine, as a control antifibrotic treatment, with Sm, a herbal compound, or SA-A, a water-soluble extract of Sm. Liver function was investigated by assessing alanine transaminase (ALT) and aspartate transaminase (AST) activities, histological analysis, hydroxyproline (Hyp) and malondiadehyde (MDA) content. In vitro, isolated cultured hepatocytes were injured with CCl4 gas for 24 h, followed by treatment with either vitamin E or various concentrations of SA-A. The extent of hepatocyte injury was monitored by analyzing various lipid peroxidative parameters such as superoxide dismutase (SOD), glutathione (GSH), catalase (CAT), lactase dehydrogenase (LDH), and glutathione peroxidase (GSH-PX) levels in hepatocyte supernatants. RESULTS: SA-A significantly decreased abnormal serum ALT activity both in acutely and chronically injured rat livers, decreased abnormal serum AST activity, Hyp and MDA content and attenuated hepatic collagen deposition. After CCl4 incubation and injury, the activities of AST, ALT CAT, GSH-PX and LDH and MDA content in hepatocyte supernatants increased significantly, but GSH levels decreased significantly. SA-A markedly improved these pathological changes in a dose-dependent manner. 10(-4) mol/l SA-A had stronger inhibitory action than vitamin E. CONCLUSIONS: Our studies suggest that SA-A has antiperoxidative effects on injured hepatocytes in liver injury and fibrosis induced by CCl4.
