护肝解纤汤治疗大鼠肝纤维化的作用观察

目的 观察护肝解纤汤治疗大鼠肝纤维化的效果及其与抗过氧化损伤的关系.方法 以四氯化碳腹腔内注射法建立大鼠肝纤维化模型,造模成功后给予自拟的含低、中、高剂量姜黄的护肝解纤汤,以小柴胡汤治疗组和复方鳖甲软肝片治疗组为阳性对照.12周后取血并处死大鼠,用放射免疫法检测肝纤维化指标.留取肝左叶同一部位新鲜肝组织,部分行HE、Masson染色,根据SSS计分系统评估肝纤维化程度;部分制成匀浆,离心后留取上清,检测超氧化物歧化酶(SOD)、丙二醛(MDA)含量.结果 护肝解纤汤能降低肝纤维化模型大鼠升高的肝纤维化指标清Ⅲ型前胶原(PC-Ⅲ)、层黏连蛋白(LN)、透明质酸(HA)含量,降低病理评分,其中以低剂量姜黄组效果明显(P<0.05).护肝解纤汤可升高肝组织中SOD,降低MDA,其中以低剂量姜黄组效果明显(P<0.05).结论 护肝解纤汤能改善大鼠肝纤维化,其抗肝纤维化作用可能与保护肝细胞膜及抗过氧化损伤有关.

Therapeutic effect of HuGanJieXian decoction on rats hepatic fibrosis

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.
