栀子黄色素对四氯化碳肝损伤小鼠的影响

目的 :　研究栀子黄色素 (GY)对 CCl4 肝损伤小鼠的保护作用。方法 :　取健康的雄性昆明种小鼠 (2 0± 2 ) g 5 0只 ,按体重随机分成 5组 ,每组 1 0只 ,即正常组 ,(饲喂正常饲料 ) ,CCl4 肝损伤组 (正常饲料 +CCl4 ) ,低剂量组 (正常饲料 +CCl4 +0 .1 ml GY溶液 /只 ) ,中剂量组 (正常饲料 +CCl4 +0 .2 ml GY溶液 /只 ) ,高剂量组 (正常饲料 +CCl4 +0 .4ml GY溶液 /只 )。GY溶液提前 5 d每天灌胃 ,对照组与肝损伤组灌胃 0 .4ml生理盐水 ,末次灌胃后 2 h给 0 .1 0 % CCl4 0 .4ml致伤。1 8h后摘除眼球取血 ,测定血清谷丙转氨酶 (SGPT)、谷草转氨酶 (SGOT)、乳酸脱氢酶 (LDH)活性 ,破腹取肝脏 ,测定肝脏丙二醛 (MDA)、谷胱甘肽 (GSH)含量及肝脏指数 ,并对肝细胞的组织形态学进行观察。结果 :　预先灌 GY溶液 ,具有显著地抑制 CCl4 引起的小鼠血清 SGPT、SGOT、LDH及肝脏 MDA含量、肝脏指数的升高以及肝脏 GSH含量的降低 ,并能显著地减轻 CCl4 引起的肝小叶内的灶性坏死。结论 :　栀子黄色素对 CCl4 致小鼠肝损伤具有保护作用

INFLUENCE OF GARDENIA YELLOW ON CCl4-HEPATOTOXICITY IN MICE

Objective: To study the protective function of Gardenia yellow (GY) against CCl 4 induced hepatotoxicity in mice.Methods: Healthy Kunming male mice, weighting (20±2) g, 10 per group were randomized into 5 groups:control group, CCl 4 injured group, low dose group(CCl 4 injured+0.1 ml GY solution), medium dose group(CCl 4 injured+ 0.2 ml GY solution) and high dose group(CCl 4 injured+0.4ml GY solution). GY solution was given i.g. 5 d prior to CCl 4 injury. Serum glutamate pyruvate transaminase(SGPT) and glutamic oxaloacetic transaminase(SGOT) and lactic dehydrogenase(LDH) activities were determined 18 h after CCl 4 injury. Hepatic malondialdehyde(MDA), glutathione(GSH) and liver index were also detected. Results: In GY treated groups, the increases of serum SGOT, SGPT, LDH activities and liver GSH were inhibited obviously. The elevations of MDA and liver index were prevented significantly. The lesions in liver lobule were ameliorated obviously. Conclusion: Gardenia yellow can protect against CCl 4 induced hepatotoxicity.
