酸化的

We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

aim to study the efficaciousness of wuling cap-sules for hepatic fibrosis in rats.methods rat models with hepatic fibrosis were induced by ccl4 compound factors and then treated with wuling capsules.pathology of liver sections,hyaluronic acid and procollagencontents in rat liver and serum were examined respectively.results pathological examinations showed that the liver cells of mod-el rats were injured seriously.collagen fibers proliferated and dissected hepatic lobules in model rats.wuling capsules could protect liver cells and reduce degrees of hepatic fibro-sis.the best effects were achieved at3.0g?

目的 研究五灵胶囊对大鼠肝纤维化的作用。方法采用以四氯化碳为主的复合因素致大鼠肝纤维化，观察五灵胶囊对肝组织病理学、肝组织和血清中羟脯氨酸、ⅰ，ⅲ型前胶原含量的影响。结果病理学检查显示，模型组大鼠肝细胞损伤严重，胶原纤维大量增生，形成假小叶。五灵胶囊组大鼠肝细胞结构破坏不明显，肝纤维化程度轻，在3.0g？kg-1 时治疗效果最好。
