蟑螂提取物抗肝损伤及抗病毒作用探讨

目的探讨蟑螂提取物抗急性肝损伤、抗HBV的作用。方法制备肝损伤动物模型,给予蟑螂提取物后分离血清,测定血清ALT和AST活性。麻鸭给药后分离血清,将血清加入体外培养的HBV-DNA克隆转染人肝癌细胞(HepG2),检测不同浓度药物对HepG2细胞分泌HBsAg、HBeAg的抑制作用。结果蟑螂提取物高、中、低3种剂量对肝损伤小鼠血清中AST和ALT活性升高均具有显著抑制作用。蟑螂提取物与拉米夫定抗HBsAg、HBeAg的指数均大于2。结论蟑螂提取物对急性肝损伤动物的肝功能有改善作用,并且能抑制HBsAg和HBeAg的复制。

Study on the effect of cockroach extract on animals with hepatic injury and its antiviral action in vitro

Objective To study the effect of extract of cockroach on animals with acute hepatic injury and its antiviral action in vitro. Methods The animal models with hepar injury were established by CCl4, bcg vaccine and lipopolysaccharide (LPS) . And the activities of ALT and AST in serum were measured. Serum of ducks was separated after cockroach extract was administrated. The serum was added to the culture fluid of HBV-DNA transfected hepatic cancer cells-HepG2. Results After the cockroach extract was administrated, the activities of ALT and AST in mouse serum were reduced. Both the therapeutic indexes of cockroach extract and lamivudine were larger than 2. Conclusions Cockroach extract can improve the liver function of animals with acute hepatic injury, and inhibit the secretion of ALT and AST in serum.
