温阳中药对实验性肝纤维化治疗作用的研究

目的　观察温阳中药对实验性肝纤维化的疗效。方法　 32只 Wistar大鼠随机分为正常对照组与模型组 ,模型组采用皮下注射 CCl4 及饮用 1 0 0 ml/ L乙醇的方法制备出大鼠肝纤维化模型后 ,随机分为治疗组与病理对照组 ,治疗组予温阳药灌胃治疗一月 ,每日一次 ,实验结束后测定肝组织羟脯氨酸含量 ,并依据改进的炎症活动度及纤维化半定量计分系统 (SSS)评分 ,观察治疗组与病理对照组的组织学变化 ,同时对 SSS纤维化计分结果与肝组织羟脯氨酸含量进行相关性分析。结果　治疗组肝组织羟脯氨酸含量较对照组明显降低 (P<0 .0 1 ) ,SSS计分炎症活动度及肝纤维化程度明显改善 ,同时纤维化计分与肝组织羟脯氨酸含量正相关。结论　温阳中药对实验性肝纤维化有减轻或逆转其肝纤维化的作用

Pathological Study of the Therapeutic Effect of Wen-yang Herbs on Experimental Liver Cirrhosis

OBJECTIVE: To observe the pathological effect of wen-yang herbs on experimental hepatic fibrosis. METHODS: Thirty-two male Wistar rats were used in this study comprising four groups. To start with, 24 rats of three groups were given subcutaneous injection of CCl4 and drinking 10% alcohol so as to make the model of hepatic fibrosis. After the establishment of the pathologic model, the rats were divided into the model group, the pathological control group and the therapeutic group by randomization. The rats of the therapeutic group were given the herbal remedies via gastrogavage, q.d. x 30. The rats of the pathological control group were given normal saline via gastrogavage, q.d. x 30. Then liver tissue Hydroxyproline (Hyp) content was examined in these 3 groups and the normal group. Quantitative marks were done according to a modified semiquantitative scoring system (SSS). The results of SSS marks and Hyp contents were analysed using Pearson's coefficient of correlation. RESULTS: The Hyp content and SSS marks of the therapeutic group decreased remarkably as compared with those of the control group (P<0.01), and the SSS marks had a strong positive correlation with Hyp content (r=0.804). CONCLUSION: Wen-yang herbs can mitigate the rats' hepatic fibrosis and promote a recovery of their experimental illness.
