Abstract:
Objective: To investigate the effect of Fu Zheng Hua Yu-319 Recipe on hepatic sinusoid capillarization in the rat of hepatic fibrogenesis. Methods: Hepatic fibrosis model rats were induced by intraperitoneal injection of dimethyl nitrosamine (DMN). thrice a week for 4 weeks, and they were divided into the treatment group which were treated with Fu Zheng Hua Yu-319 Recipe for 4 weeks, and the model control group. Serum and hepatic tissue were taken for examination of pathohistology, microstructure by electron microscopy, immunohistochemistry, and hydroxyproline content in the liver tissue and hepatic function. Results: In the normal group, peripheral cytoplasma of endothelial cells in the hepatic sinusoid is very thin with a lot of small fenestra, and no basement membrane under endothelium was found. In the model group, crookedness and stricture of the hepatic sinusoid were found , and the fenestra in cytoplasma of the endothelial cell reduced or disappeared with obvious basement membrane, and hemorrhage necrosis in the liver tissue could be found, with a great proliferation of connective tissue in the portal area, and fibrous septum extended towards into the lobuli, the content of hydroxyproline (HYP) in the liver tissue increased significantly. The VI factor-related antigen, a-actin of smooth muscle, LM and type IV collagen positive staining on the hepatic sinusoid wall increased significantly with a wider range as compared with the normal rat. In the treatment group, the extents of crookedness and stricture of hepatic sinusoid and reduction and disappearence of endothelial fenestra were lower, with thiner or discontinuous basement membrane, and a part of hepatic sinusoid construction approached to normal, and degeneration and necrosis of hepatic cells were mild and fibrous septum in the liver tissue decreased significantly, and HYP content decreased significantly (P
