Abstract

The influence of ACTH, CHM and of ACTH + CHM was studied on lipid metabolism of lungs of rats by usage of a radioactive precursor 14C-acetate. It was established that the biosynthesis of total lipids, of triacylglycerols as well as of free fatty acids was increased under the influence of ACTH and CHM as this effect was mostly manifested after combined action of ACTH and CHM. The investigated factors manifested inhibiting effect on the synthesis of free cholesterol and total phospholipids. ACTH stimulated incorporation of 14C-acetate in the glycerol part of triacylglycerols as well as of the total phospholipids, while CHM and the combination of CHM and ACTH had inhibiting effect on the biosynthesis of the glycerol part of triacylglycerols and of total phospholipids.

[促肾上腺皮质激素(ACTH)和环己亚胺(CHM)对大鼠肺脂质生物合成的影响]。
采用放射性前体14c -乙酸酯研究了ACTH、CHM及ACTH + CHM对大鼠肺脂质代谢的影响。结果表明,在ACTH和CHM的作用下,总脂质的生物合成、甘油三酯的生物合成以及游离脂肪酸的生物合成均有所增加,而这种作用主要是在ACTH和CHM共同作用后表现出来的。所研究的因素对游离胆固醇和总磷脂的合成均有抑制作用。ACTH刺激了14c -乙酸酯在三酰甘油甘油部分和总磷脂中的掺入,而CHM和CHM与ACTH的联合对三酰甘油甘油部分和总磷脂的生物合成有抑制作用。
