摘要: 为了证实大蒜对动物肝损伤形成的抑制作用,本研究采用CCl4和含有10%猪板油的高脂饲料获得肝损伤大鼠动物模型并经HE染色确认。在高脂饲料中添加1%、3%、5%和7%大蒜泥,同时在饮用水中加入1%大蒜浸出汁,喂食30d后,观察大鼠肝脏组织学和形态学的变化并测定其甘油三脂和胆固醇含量,结果发现,在添加大蒜的高脂饲料的雄性和雌性模型组中,甘油三脂和总胆固醇含量都有所降低,其中①添加3%、5%、7%大蒜泥饲喂的雌性大白鼠其肝脏中甘油三脂含量都显著降低(p<0.05),而在雄性大白鼠上只有添加5%和7%的大蒜泥才有效果(p<0.05);②添加5%、7%大蒜泥饲喂的雌性大白鼠其肝脏中总胆固醇含量显著(p<0.05)降低,在雄性大白鼠上添加7%的大蒜泥才有显著(p<0.05)降低效果;③雄性和雌性大白鼠脂肪肝模型间甘油三脂和总胆固醇的含量有显著差别(p<0.01)。结论:①大蒜对肝损伤实验大鼠肝脏的甘油三脂和总胆固醇的含量升高有抑制作用;②高脂饲料中添加的大蒜数量与总胆固醇的含量降低呈正相关;③大蒜对雌性和雄性大鼠肝损伤的抑制效果不同,雌性大鼠对大蒜抑制肝损伤的效果更敏感。

Abstract: Objective:To study the inhibition of garlic on the development of fatty liver.Methods:Fatty liver models were induced by CCl4 and chronically feeding with high fat diet containing 10% lard in rats and confirmed by HE dyeing.In addition to the rats of model group,we had other two groups with male and female sub-group in each one — the rats of control group that were fed regularly and the rats of garlic groups that were fed different doses-1%,3%,5%,7% of garlic mash,high fat diet and water with 1% garlic juice.30 days later,the level of triglyceride(TG)and total cholesterol(TC)of liver for different diet groups rats of both genders were analyzed and compared.Results:(1)Compared with model group,the levels of TG and TC in garlic groups were decreased with different extent —for female,TG and TC were significantly decreased for dose 3%,5%,7%,and 5%,7%,respectively;while for male,5% and 7% garlic mash were effective to reduction of TG,and only 7% were effective to reduction of TC.(2)There were significant correlation between dose of garlic mash and reduction of TC(male:R2=0.9742,female:R2=0.9655).Conclusions:Garlic diet had effects on inhibiting the increases of TG and TC of liver in model rats and inhibition effect was different for male and female rats,and female rats were more sensitive to high fat diet and garlic diet.
