Abstract

The release of neurosecretory granules by exocytosis was ultrastructurally observed in the neurohypophysis pars nervosa (posterior lobe) of the frog Rana temporalia with the tannic acid-Ringer fixation method. Electron microscopic analysis with the immunogold method revealed that many of putative neurosecretory granules displayed oxytocin-like immunoreactivity.

摘要

采用单宁酸-林格氏固定法，在超微结构上观察了颞蛙神经垂体神经部（后叶）中神经分泌颗粒通过胞吐作用的释放。用免疫金法进行的电子显微镜分析显示，许多假定的神经分泌颗粒呈现出催产素样免疫反应性。
