近年来发现某些疾病时,Na~+K~+-ATP酶的活性升高或降低。而该酶是细胞膜上一种重要的水解酶,广泛存在于人和哺乳动物各种细胞质膜及内膜上,它在能量转换,离子转运和信息传递等细胞基本功能上有重要作用。为研究其在疾病过程中上述功能的改变,我们首先制备了家兔红细胞膜并测定了Na~+,K~+-ATP酶活性。 In recent years, the discovery of certain diseases, Na ~ + K ~ + -ATP enzyme activity increased or decreased. The enzyme is an important cell membrane hydrolase, widely present in human and mammalian plasma membrane and endometrium, which plays an important role in the basic functions of cells such as energy conversion, ion transport and information transmission. In order to study the changes of these functions in the process of disease, we first prepared rabbit erythrocyte membrane and assayed the activity of Na ~ + and K ~ + -ATPase.
