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