Administration of beryllium per se caused severe degenerative and necrotic changes in liver, kidney, lungs and spleen. Its administration reduced glycogen content, activity of alkaline phosphatase and adenosine triphosphatase in these oreans. On the contrary, activities of acid phosphatase and glucose-6-phosphatase were increased singificantly. In Liv-52 primed rats significant recoupment was observed in all the parameters展开更多

This study was undertaken to investigate the hepatoprotective effect of SC against liver injury induced by CC14 intoxication. Animals were divided into five groups. Group I, served as normal control. Group II received 2 mL CC14/kg b.w. diluted with olive oil, at 1：1 ratio on day 11. Groups III and IV were pre-treated orally respectively with 100 and 200 mg/kg b.w. aqueous roots extract of SC for 10 days followed by subcutaneous injection of CC14 （2 mL/kg b.w.）, once on day 11. Group V were orally given Liv-52 （100 mg/kg b.w.） once daily for 10 days followed by subcutaneous injection of CC14 （2 mL/kg b.w.）, once on day 11. Our results show that, the activity of serum hepatic enzymes （ALT, AST, and ALP） were significantly elevated in guinea pigs treated with CC14, while both the SC root extract and Liv-52 reduced significantly these enzymes activity. Also, the levels of glucose, urea and cholesterol were decreased when compared with intoxicated control. Histopathological examination of intoxicated animals showed dilation, hemorrhage, vacuolization, inflammation and necrosis indicating liver damage, while the animals received SC or Liv-52 that showed less pathological effects or normal liver when compared to animals treated with CC14 alone. Biochemical and histological results confirm the hepatoprotective effect of aqueous extract of SC.展开更多

Treatment of Liv 52,silymarin and ethanolic extract of Terminalia paniculata(200 mg/kg) altered levels of biochemical marker and showed significant hepatoprotective activity.Ethanolic extract revealed the presence of phenolic compound and flavanoids.Our findings suggested that ethanolic bark extract of Terminalia paniculata possessed hepatoprotective activity in a dose dependent manner.Conclusions:Terminalia paniculata possesses hepatoprotective activity.It could be an effective and promising preventive agent against PCT induced hepatotoxicity.展开更多
