摘要
AIM： To evaluate the effects of osthole on fatty liver, and investigate the possible mechanism. METHODS： A quail model with hyperlipidemic fatty liver and rat model with alcoholic fatty liver were set up by feeding high fat diet and alcohol, respectively. These experimental animals were then treated with osthole 5-20 mg/kg for 6 wk, respectively. Whereafter, the lipid in serum and hepatic tissue, and coefficient of hepatic weight were measured. RESULTS： After treatment with osthole the levels of serum total cholesterol （TC）, triglyceride （TG）, lower density lipoprotein-cholesterol （LDL-C）, coefficient of hepatic weight, and the hepatic tissue contents of TC and TG were significantly decreased. The activity of superoxide dismutase （SOD） in liver was improved. In alcohol-induced fatty liver rats, the level of malondialdehyde （MDA） in liver was decreased. In high fat-induced fatty liver quails, glutathione peroxidase （GSH-PX） in liver was significantly improved. The histological evaluation of liver specimens demonstrated that the osthole dramatically decreased lipid accumulation. CONCLUSION： These results suggested that osthole had therapeutic effects on both alcohol and high fatinduced fatty liver. The mechanism might be associated with its antioxidation.
瞄准：在脂肝上评估 osthole 的效果，并且调查可能的机制。方法：有 hyperlipidemic 脂肝的一个鹑模型和有含酒精的脂肝的老鼠模型被分别地喂多脂饮食和白酒建立。这些实验动物然后分别地为 6 wk 与 osthole 5-20 mg/kg 被对待。然后，在浆液的类脂化合物和肝的织物，和肝的重量的系数被测量。结果：胆固醇(TC ) ，甘油三酸酯(TG ) ，更低的密度脂蛋白胆固醇(LDL-C ) ，肝的重量的系数，和肝的织物 TC 和 TG 满足的有浆液的层次总计的 osthole 的术后疗法显著地被减少。在肝的超级氧化物歧化酶(草皮) 的活动被改进。在导致白酒的脂肝老鼠，在肝的 malondialdehyde (MDA ) 的水平被减少。在高导致脂肪的脂肝鹑，在肝的谷胱甘肽过氧化物酶(GSH-PX ) 显著地被改进。肝标本的组织学的评估证明 osthole 戏剧性地减少了类脂化合物累积。结论：这些结果建议 osthole 在酒精和高导致脂肪的脂肝上有治疗学的效果。机制可能与它的反氧化被联系。
