Abstract
A correlation between the spike activity and ferrous deposits in the Ranvier nodes of afferent fibers has been revealed in the frog bladder. The degenerated fibers reveal neither deposits, nor spike activity. The native fibers reveal deposits in the presence of spike activity. When the spike activity is suppressed by procainamide the node affinity to ferrous ions is retained. It is suggested that positive cytochemical reactions in the nodes demonstrate the retention of the initial morpho-functional structure of afferent fibers.
摘要
在蛙膀胱中已发现传入纤维郎飞结处的锋电位活动与亚铁沉积之间存在相关性。退化的纤维既无沉积，也无锋电位活动。正常纤维在有锋电位活动时会出现沉积。当用普鲁卡因胺抑制锋电位活动时，结对亚铁离子的亲和力仍保留。提示结中的阳性细胞化学反应表明传入纤维保留了初始的形态功能结构。
