Abstract:
Objective To observe the effect of Kadsura coccinea on the expression of Bcl-2, Bax and proliferating cell nuclear antigen (PCNA) in liver tissue of experimental hepatic fibrosis rats, to further discuss the mechanism of anti-liver fibrosis. Methods Sixty SD rats were randomly divided into normal control group, model control group, colchicine group, low-dose Kadsura coccinea group (2.5 g·kg-1) and high-dose Kadsura coccinea group (5 g·kg-1) (n = 12) . All groups except the normal control group were treated with CCl4, rich fat and poor protein to establishexperimental hepatic fibrosis animal model. The second day after modeling, drug treatmentwas started, till the end of the sixth week. Pathological section of the rat' s liver was examined in order to observe its tissue under a optical microscope. Liver tissues were taken to examine the degree of liver fibrosis by HE and Masson staining, and the expression of Bcl-2, Bax and PCNA protein were detected by immunohistochemistry. Results Kadsura coccinea relieved the degree of necrosis of liver cells, liver fat' s degeneration and collagen fiber hyperplasia significantly. Compared with the model control group, expression of Bax in low-,high-dose Kadsura coccinea group and colchicine group were significantly decreased, and the expression of PCNA in hepatic fibrosis rats were enhanced(P<0.05 or P<0.01) . Conclusion Kadsura coccinea has a certain inhibitory effects on experimental hepatic fibrosis in rats, and its mechanism may be related to inhibiting the expression of Bax protein and promoting the expression of PCNA protein in liver tissues.
