Experimental Center of National Level One, Hubei Traditional Chinese Medica l College, Wuhan 430061）Abstract To investigate the protective effects of Jiaweisinisa n on acute liver injury induced by intraperitoneal injection of D-ga lac-tosamise, serum superoxide dismutase, malondialdehyde , glutathioe contents were measured. The pathological changes of liver wer e observed simultaneously. The results showed that JWSNS could decrease serum MD A content, but increase serum SOD and GSH activities in acute liver injury induc ed by D-GalN. It was also found that JWSNS could alleviate the degeneration and necrosis of the hypatocytes.
