Müller (glial) cells from the rabbit retina were isolated by means of papain and mechanical dissociation. Their Na+,K+-adenosine triphosphatase (ATPase) activity was measured using a radiochemical method, and its K+ dependence was determined. In contrast to that of photoreceptors (data from the literature), the Na+,K+-ATPase of Müller cells could be shown to increase its activity greatly when the [K+] was enhanced up to 10 mM. The functional implications of this behaviour for the K+ clearance in the retina are discussed.
通过木瓜蛋白酶和机械解离的方法分离出兔视网膜的 Müller（神经胶质）细胞。使用放射化学方法测量其 Na⁺、K⁺ - 三磷酸腺苷酶（ATP 酶）活性，并确定其对 K⁺ 的依赖性。与光感受器的情况（文献数据）相反，当 [K⁺] 增加到 10 mM 时，Müller 细胞的 Na⁺、K⁺ - ATP 酶活性会显著增加。讨论了这种行为对视网膜中 K⁺ 清除的功能意义。
