title: Ultrastructural demonstration of exocytosis of neurosecretory granules in the neurohypophysis of the frog Rana temporalia.
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.
