     摘要：目的观察肝龙胶囊对鸭乙型肝炎病毒的抑制效果和对实验性肝损伤的保护作用。方法(1)以鸭乙型肝炎病毒(DHBV)静脉注射感染雏鸭为模型，于感染第7天后分组灌胃肝龙(GL)胶囊浸膏0.5，1.5，3.0 g·kg1·d1，阳性对照组给予无环鸟苷(ACV)或磷羧基甲酸钠(PFA)。采用斑点杂交方法检测鸭血清DHBVDNA，以病毒抑制率为疗效指标；(2)以昆明种小鼠腹腔注射CCl4肝损伤为模型，给予GL浸膏(200 mg·kg1)。测定SGPT值，并取肝脏作病理形态学观察。结果(1)GL三个不同剂量组对DHBV均有不同程度的抑制作用，有一定的量效关系；(2)GL降低CCl4肝损伤小鼠血清SGPT值并减轻肝细胞损伤。结论肝龙胶囊可抑制雏鸭体内DHBVDNA的复制并能保护CCl4所致的小鼠肝损伤。

    Abstract：ObjectiveTo observe the antiviral activity of Ganlong Capsule against duck Hepatitis B virus( DHBV) and its protective effects on experimental liver injury in vivo.Methods(1) Experimental researches on antiviral activity of Ganlong Capsules against duck hepatitis B virus: The duck Hepatitis B model was made by injecting DHBV into the veins of one-day-old Beijing duck on the seventh day after infected by DHBV, Ganlong Capsule was given by intragastric administration for 10 days to group I (0.5 g·kg1·d1), group II(1.5 g·kg1·d1), group III(3.0 g·kg1·d1), bid×10 d, and detected the levels of DHBV-DNA in the duck blood sera obtained separately on the day before giving Ganlong Capsule, the fifth day and tenth day after giving Ganlong Capsule, and the third day after withdrawing Ganlong Capsule, by serum dotblot hybridization. The trial was compared with acyclovor(ACV) or phosphonoformate(PFA). (2) Protective effects of Ganlong capsule on experimental liver injury in mice: Acute hepatic injury was induced by intraperitoneal injection of 0.2% CCl4 10 ml·kg1, Ganlong(200 mg·kg1) was given by intragastric or intraperitoneal administration for 2 days, bid. The serum SGPT were examined and the histopathological changes of hepatic tissue was measured.Results(1)The results of three experiments showed that the levels of sera DHBVDNA decreased in the treatment groups of Ganlong, and in a dose-effect manner. The group III(3.0 g·kg1·d1) inhibited (P<0.01) the serum DHBVDNA significantly, and after stopping the treatment for 6 days, serum DHBV-DNA level did not return significantly, and the inhibit effects were no different,compared with the treatment group of phosphonoformate(PFA) or acyclovor(ACV). (2) Ganlong(200 mg·kg1) could obviously inhibit the increase of serum SGPT, and histological examination showed that hepatic damages of Ganlong treated mice were less severe than those of CCl4 control group.ConclusionThese results suggested that Ganlong Capsule markedly inhibited duck hepatitis virus replication and had protective effects on experimental hepatic injury in vivo. ......
