AIM
To study the effect of oral oxymatrine on expressions of type I, III, IV collagen in rat liver fibrosis induced by CCl4.
METHODS
140 male Wistar rats were randomly divided into normal control group (n = 20), CCl4 group (n = 30), and oxymatrine-treated group including low-dose subgroup (n = 30), median-dose subgroup (n = 30), and high-dose subgroup (n = 30). Low, median, and high-dose oxymatrine subgroups were given 30, 60 and 100 mg/kg oxymatrine by daily gastrogavage for 12 wk, respectively. Inflammation and fibrosis degree of liver tissues were examined by hematoxylin-eosin staining. Expressions of type I, III, IV collagen were detected by immunohistochemistry, and ultrastructural changes were observed by electron microscopy.
RESULTS
Liver histologic examination showed that the degree of liver inflammation and fibrosis were more serious in control group than in oxymatrine-treated groups. In control group, the amounts of collagen type I, III, IV deposits were observed, and type III and IV collagen deposits were the main constitutes of hepatic sinusoid capillarization. But in oxymatrine-treated groups, type I, III, IV collagen deposits were less, hepatic sinusoid capillarization was not obviously found. Electron microscopy showed that the degree of hepatocyte injury was more serious in control group than in oxymatrine-treated groups.
CONCLUSION
Oral oxymatrine might decrease expression of type I, III, IV collagen in rat liver fibrosis model induced by carbon tetrachloride, suggesting oral oxymatrine might have anti-fibrogenic effect.
