Abstract:

Objective To investigate the protection of Angelica sinensis polysaccharide(ASP) on ephedrine induced hepatic injury in mice. Methods Seventy-two mice were randomly divided into 4 groups:the natural control group,experiment control group,ASP1 group, and ASP2 group.The experimental control group and ASP groups were intraperitoneally injected with a 4.0g/L of ephedrine 0.2ml twice a day for 15 days, and the natural control group was injected with a same amount of saline.The ASP groups were irrigated to stomach with 0.3ml Angelica sinensispolysaccharide solution (12.5g/L,25.0g/L)1 hour after ephedrine injection,the natural control group and experiment control group were irrigated to stomach with a same amount of saline.The mice were sacrificed at 5 day,10day,and 15 day after treatment,respectively.The morphological observation was used to observe pathological changes of hepatic tissues.Activities of hepatic histologicalsuperoxide dismutase(SOD)and plasma γ-glutamyltransferase(γ-GT), alkaline phosphatase (AKP), glutamic-pyruvic transaminase (ALT), glutamic-oxalacetic transaminase(AST),as well as content of malonaldehyde(MDA)were detected by colorimetry.The expressions of Bax protein and Caspase-3 protein were measured by immunohistochemistry in liver of mice. Results There were various degree damages in hepatic tissues,hepatic cords were disorganized,liver cells were loose and liver sinusoid expanded,the activity of γ-GT、AKP、ALT、AST in plasma were significantly increased,the activity of SOD in liver tissue was significantly reduced,the content of MDA in liver tissue was increased significantly,the expression of Bax and Caspase-3 protein in liver were significantly increased.Compared with the experimental control group,pathological damage of liver was significantly improved,the activity of plasma γ-GT, AKP, ALT, AST were significantly reduced,the activity of SOD in liver tissue was increased significantly,however the content of MDA was significantly decreased and the expressions of Bax and Caspase-3 protein in liver were reduced in Angelica sinensis polysaccharide group. ConclusionAngelica sinensis polysaccharide can improve liver tissue antioxidant capacity and promote reparation of cell injury and protect hepatic injury which is induced by ephedrine.
