Abstract:
Objective On the basis of the lasted clinical experience,our group will discuss the treatmented mechanism of Chinese herb kang-xian-er-hao(KXEH) ameliorate hepatic cirrhosis. Methods Male wistar rats were divided into five groups,excepted for normal group N,the remnant four groups were all given intraperitoneal injection of porcine serum((0.5) ml/time,2 times/week,total 12 weeks).In KXEH early treatment group B,the rats were fed with KXEH by gavage,1 g/100 g,once a day at the third week.In KXRH late treatment group C,the rats were fed with KXEH by gavage,1 g/100 g,once a day at the ninth week.In ?-interferon treated group D the rats were subcutaneous injection ?-interferon((0.1) million) every day at the ninth week.The model group A and normal group N were fed with the same amount of saline by gavage.The rats were killed at the end of the twelfth weeks,the formation of liver fibrosis was observed with HE stain and Masson stain.The expression of Smooth muscle actin(SMA) was observed by immunohistochemistry.As well as SMA,collagen Ⅰ、Ⅲ mRNA and Smad3 mRNA,which is TGF-?1 downstream signal,were detected in liver samples with RT-PCR assay. Results In KXEH treated group B and C,the body weight was heavier,the size of liver and spleen was smaller and the ratio of liver weight/body weight and spleen weight/body weight was decreased compared with the model group A(P
