Abstract
The rats were irradiated in the doses 1, 5, 4, 7 and 10 Gr and on the 1, 8, 15, 22 and 30 day after the irradiation activity of Ca(2+)-ATPase and Mg(2+)-ATPase and peroxidation lipids in the thymocytes was determined. It was found that postradiation changes in activity of Mg(2+)-ATPase were characterized by a higher sensitivity to the processes of lipids peroxidation as compared to Ca(2+)-ATPase.
摘要
将大鼠分别用1、5、4、7和10戈瑞的剂量进行照射，并在照射后的第1、8、15、22和30天测定胸腺细胞中Ca(2+)-ATP酶、Mg(2+)-ATP酶的活性以及过氧化脂质。结果发现，与Ca(2+)-ATP酶相比，辐射后Mg(2+)-ATP酶活性的变化对脂质过氧化过程更为敏感。
