酒精对肝脏有损害作用是众所周知的。本文重点研究叶酸对酒精所致的肝损害是否有保护作用。实验用68只NIH小鼠并分成三组,正常组20只(A组),酒精组24只(B组)、叶酸酒精组24只(C组)分别用上述物质灌喂1、2、3、4周后,分期处死动物。用组织化学、电镜等方法观察。结果表明:叶酸可使肝脏SDH、Mg~(++)—ATPase、G-6-Pase的活性明显增强,并使糖原合成增加;使ACP活性降低。对线粒体、内质网等超微结构无损害。这提示叶酸对已受酒精损害的肝细胞的功能和结构有明显的保护作用。 Alcohol damage to the liver is well known. This article focuses on the folic acid on alcohol-induced liver damage whether there is a protective effect. Sixty-eight NIH mice were randomly divided into three groups: normal group (A group), alcohol group (B group) and folic acid and alcohol group (C group) After 4 weeks, the animals were sacrificed by staging. With histochemistry, electron microscopy and other methods. The results showed that folic acid significantly enhanced the activity of SDH, Mg ~ (++) - ATPase and G-6-Pase in liver and increased the synthesis of glycogen and decreased the activity of ACP. Right mitochondria, endoplasmic reticulum and other ultrastructural damage. This suggests that folic acid has a significant protective effect on the function and structure of hepatocytes that have been damaged by alcohol.
