To evaluate the value of two histological quantitative methods of hepatic fibrosis: semiquantative scoring system (SSS) and image analysis by computer. The prophylactic and therapeutic effect of Ganzhifu on hepatic fibrosis induced by CCl4 were studied on a total 73 of specimens from liver tissue of rats. All specimen were analyzed quantatively by two methods of SSS marks and image analysis respectively. Difference between groups was compared and hydroxyproline (Hyp) content of each liver tissue was examined. Correlation analysis was done between SSS marks, image analysis and Hyp content. Both prophylactic and therapeutic study showed the same information. Results of SSS marks, image analysis and Hyp content were coincidence. It suggest that both SSS marks and image analysis were interrelated well with Hyp content (P < 0.01). The result suggests that both SSS marks of hepatic fibrosis and image analysis by computer can be taken as reliable histological quantitative method of hepatic fibrosis.
