To assess the hepatoprotective effect provided by fresh garlic on fatty liver induced by high-fat diet.
This experimental study was carried out at BMSI, JPMC from October to November 2008. Thirty adult albino rats, 200-240 gram weight, were divided into three groups. Group A received control diet, Group B received high-fat diet (20 mg butter/100 gm diet) and Group C received high-fat diet with fresh garlic (20 mg butter with 6 gm fresh garlic/100 gm diet). The groups were further divided on the basis of duration of treatment, four weeks and eight weeks respectively. The rats were sacrificed, liver removed, weighed and relative liver weight calculated. Hepatic tissue was processed and tissue slides stained with haematoxylin and eosin.
There was significant increase in relative liver weight in group B animals as compared to the control animals, which decreased significantly in group C. Haematoxylin and eosin stained sections revealed ballooned hepatocytes having vesicular appearance with pyknotic nuclei in high-fat group which were preserved to a great extent in group C animals.
This study has shown that use of fresh garlic along with high-fat diet prevents its damaging effects on liver to a great extent.
评估新鲜大蒜对高脂饮食诱导的脂肪肝的肝脏保护作用。
本实验研究于2008年10月至11月在卡拉奇真纳医学院基础医学科学研究所进行。将30只体重200 - 240克的成年白化病大鼠分为三组。A组给予对照饮食,B组给予高脂饮食(每100克饮食含20毫克黄油),C组给予含新鲜大蒜的高脂饮食(每100克饮食含20毫克黄油和6克新鲜大蒜)。根据治疗持续时间,每组再进一步分为两组,分别为四周组和八周组。处死大鼠,取出肝脏,称重并计算相对肝脏重量。对肝组织进行处理,组织切片用苏木精和伊红染色。
与对照组动物相比,B组动物的相对肝脏重量显著增加,而C组显著降低。苏木精和伊红染色切片显示,高脂组肝细胞呈气球样变,有囊泡样外观,核固缩,而C组动物的肝细胞在很大程度上得以保存。
本研究表明,高脂饮食中添加新鲜大蒜可在很大程度上防止其对肝脏的损害作用。
