The influence of methionine and vitamin E, compounds intensifying thiol metabolism, on thiamine-phosphate level and thiamine-dependent dehydrogenase activity was studied in the liver of rats with varying thiamine providing: in case of its alimentary deficiency, and intensified thiamine consumption due to rat feeding with high-carbohydrate food. Methionine administration to vitamin B1-deficient rats led to a significant rise in thiamine-phosphate content and normalized alpha-ketoacid dehydrogenase acidity and non-protein SH-group level. Combined administration of thiamine with methionine and vitamin E increased the level of parameters studied. Methionine and vitamin E administered with thiamine intensified the regulatory action of thiamine on pyruvate dehydrogenase activity in the animals fed high-carbohydrate ration.
研究了甲硫氨酸和维生素E(强化硫醇代谢的化合物)对硫胺素磷酸盐水平和硫胺素依赖性脱氢酶活性的影响,实验对象为硫胺素供应情况不同的大鼠肝脏:一种是食物性硫胺素缺乏的大鼠,另一种是因喂食高碳水化合物食物而硫胺素消耗增加的大鼠。给维生素B1缺乏的大鼠施用甲硫氨酸导致硫胺素磷酸盐含量显著升高,并使α-酮酸脱氢酶活性和非蛋白巯基水平恢复正常。硫胺素与甲硫氨酸和维生素E联合施用提高了所研究参数的水平。在喂食高碳水化合物日粮的动物中,甲硫氨酸和维生素E与硫胺素一起施用增强了硫胺素对丙酮酸脱氢酶活性的调节作用。
