Abstract
The activity of aspartate-(AST) and alanine (ALT) aminotransferases was studied in the tissues and blood serum of rats under conditions of A-avitaminosis. The activity of aminotransferases is established to increase in the blood serum and liver. In the small intestine mucose it drops sharply. The activity of ALT in the heart of the A-avitaminous animals lowers as well whereas AST does not change essentially its activity. Short fasting has no effect on the activity of the mentioned enzymes.
摘要
在维生素A缺乏症的条件下，研究了大鼠组织和血清中天冬氨酸转氨酶（AST）和丙氨酸转氨酶（ALT）的活性。已确定转氨酶的活性在血清和肝脏中升高。在小肠黏膜中其活性急剧下降。维生素A缺乏动物心脏中的ALT活性也降低，而AST的活性基本没有变化。短期禁食对上述酶的活性没有影响。
