Methods: Apinoid wistar white rats ,quality standard was about 200 ? 30 gram (belong to SPF animal in experimental animal center ,FMMU)were randomly divided into experimental group and control group.Experimental group was gived hypodermic injection at a dose of 0.3ml/100g by 60 percent carbon tetrachloride olive solution every four days and drinked 50ml/L ethyl alcohol. we would divide course of cirrhotic rats models into three stages : early stage (the 25th day) is fatty degenerationnecrosis ;middle stage (the 45th day) is proliferation of fibrous tissue ; advanced stage (the 65th day) is formation of pseudolobuli .
