Oxymatrine (OM) is a kind of Chinese herb that is found to have some effects on liver fibrosis. We aimed to determine the effects of OM on hepatic fibrosis and explore the possible mechanism. METHODS: Thirty-two rats were randomly divided into four groups; 16 were used to develop hepatic fibrosis by carbon tetrachloride (CCI4) and treated with or without OM, and 16 were used as controls. The expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) and α-smooth muscle actin (α-SMA) in the livers of rats was detected by immunohisto-chemical assay. Liver pathology was determined by H&E staining and reticulum staining. RESULTS: In CCl4-injured rats, the normal structure of lobules was destroyed, and pseudolobules were formed. Hyperplasia of fibers was observed surrounding the lobules. While the degree of fibrogenesis in liver tissues was significantly decreased in those rats with OM-treatment compared with those without OM treatment. The pseudolobules were surrounded by strong, multi-layer reticular fibers, which netted into pseudolobules in CCl4-injured rats, however, there was a significant decrease in reticular fibers in OM-treated rats. The expression of TIMP-1 in hepatic cells was weak in control groups, but strong in CCl4-injured groups, however, the expression of TIMP-1 was significantly inhibited by OM (F = 52.93, P<0.05). There was no significant change in the expression of α-SMA between CCl4-injured rats with or without OM treatment (F= 8.99, P>0.05). CONCLUSION: OM effectively inhibits CCl4-induced fibrogenesis in rat liver tissues, probably by reducing the expression level of TIMP-1.展开更多

After ig crude extraction of SW to S180 sareoma rooted in mouse and EMT6 model mice with breast carcinoma for 12 d at dose of 16 mg/kg, the inhibitory rates of weight amounts to 49.7% and 49.4% respectively (P<0.01). Given crude extraction of SW at 4 mg/kg combined with irradiation at 5 Gy60Co-γ, the inhibitory rate of weight of S180 amount to 64.5% (P<0.01). It shows that SW has obviously antineoplastic.展开更多

Methods： The mice were selected as the research object, and SPSS （statistic package for social science）, matrine and matrine liposome were used for grouping. The antitumor effects of EAC, S 180 and H22 were evaluated by tumor weight, thymus weight and spleen weight. Results： The inhibitory effect of matrine liposome on EAC, S180 and H22 in mice was significantly higher than matrine, P 〈 0.05, which had statistical significance. Conclusion： Matrine liposome can effectively enhance the anti-tumor effect and improve the immunity of animals, which is worthy of clinical promotion.展开更多
