Abstract
A novel giant axon preparation from the squid Alloteuthis is described. Properties of in situ and isolated axons are similar. Periaxonal K+ accumulation is a function of the physiological state of the animal and of the axon and its sheathing layers. Carefully dissected isolated axons, and axons in situ in a healthy mantle, show much less K+ accumulation than previously reported in squid. It is suggested that the Schwann cells are involved in the observed K+ regulation.
摘要
描述了一种来自长鳍乌贼的新型巨轴突制备方法。原位轴突和分离轴突的特性相似。轴突周围钾离子的积累是动物、轴突及其鞘层生理状态的函数。仔细解剖分离的轴突以及健康外套膜中的原位轴突，其钾离子积累比之前报道的鱿鱼中的要少得多。有人提出，施万细胞参与了所观察到的钾离子调节过程。
