愈肝胶囊的抗鸭乙肝病毒作用研究

目的:观察愈肝胶囊抗鸭乙肝病毒作用.方法:选1日龄广州麻鸭50只接种病毒,随机分为无环鸟苷200 μg/kg,愈肝胶囊6.5 g/kg,3.25 g/kg及病毒对照组,每日一次口服,分别观察其抗DHBV的作用.试验结束时,取肝组织做病理切片光镜观察.结果:愈肝胶囊6.5 g/kg组在给药后第5天,第10天和停药后第3天,鸭血清DHBV DNA水平均明显下降,与给药前自身比较及病毒对照组比较,差异均有显著性(P＜0.01);3.25 g/kg愈肝胶囊组在给药后第3天及停药后第3天与病毒对照组比较有显著性(P＜0.05),而与给药前无统计学差异.结论:愈肝胶囊具有抗鸭乙肝病毒及改善鸭肝脏炎性病变作用,且具有明显量效关系.

Experimental Study on Anti-DHBV Effect of Yu Gan Capsules

Objective: To observe the antiviral effect of Yu Gan capsules against DHBV in ducks. Methods: 50 Guangzhou brown spot ducks were used in this experiment. After the ducks were infected DHBV, they were divided into four groups at random(ACV 200 mg/kg group, Yu Gan capsules 6.5 g/kg group, Yu Gan capsules 3.25 g/kg group and virus control group) and Drugs were given by stomach once a day. Blood samples were taken from each duck and tested for DHBV-DNA's level. Researches left liver tissue were sheared and used for optical analysis. Results: In Yu Gan capsules 6.5 g/kg group, DHBV-DNA's level in ducks' serum decreased on the 5 th and 10 th days after treatment and the 3th day after recession of treatment. There was a significant difference in the DHBV-DNA's level between the days after treatment and before treatment. there was also significant difference in the DHBV-DNA's level between Yu Gan capsules 6.5 g/kg group and virus control group(P<0.01). Whereas, no inhibition effect was found in Yu Gan capsules 3.25 g/kg group. Conclusion: Yu Gan capsules have functions on anti-DHBV in duck.
