title: [Ultrastructure of the gastric endocrine cells of hungry and fed sexually immature rats].
abstract: Six types of endocrine cells (G, D, D1, EC, ECL and A-like) were identified in gastric mucosa of immature rats by electron microscopy. They differ in the structure, way of formation, maturation and release of their secretory granules. They are also distinguished by the degree of the development of other cytoplasmic structures. Feeding after a long-term (48 h) starvation causes changes in te size and density of activation of the synthetic processes. These facts indicate the role of the above cell and their products (gastrin, histamine) in the stimulation of gastric secretion in the early stages of digestion.
