Abstract:
Objective To study the protective effects of aqueous extract and alcohol-soluble extract of Isodon lophanthoides var.gerardianus (Benth.)Hara (ILVG) on immunity hepatic injury induced by concanavalin A (Con A) in mice.Methods One hundred and eight NIH mice were allocated into normal control group,model group,ILVG groups of aqueous extract and alcohol-soluble extract (low-,middle-and high-dosage),and bifendate group randomly.In the experimental groups,mice received either ILVG aqueous extract or alcohol-soluble extract (18.20 g?kg-1,9.10 g?kg-1,4.55 g?kg-1 respectively) or Bifendate (45 mg?kg-1) by gastric perfusion daily for consecutive 5 days.In the 5th day,Con A (20 mg?kg-1) was injected into mice via the tail vein 4h after administration.And then the blood was obtained by picking out the eyeball and the serum was separated after 8-hour fasting.The serum levels of ALT and AST were analyzed,the body weight as well as the weight of liver,spleen and thymus were measured,and pathological features of hepatic tissue were observed.Results ILVG can decrease the ALT and AST,restrain the enlargement of liver and the shrinkage of thymus and reduce the necrosis of hepatic tissue.Conclusion Aqueous extract and alcohol-soluble extract of ILVG possess the effects of protecting liver from immunity injury induced by Con A in NIH mice.
