title: An immunohistochemical study of endocrine cells in the stomach of hypertensive rats.
abstract: Essential hypertension is a complex disease with both genetic and environmental determinants. The effect of spontaneous hypertension on the distribution and occurrence of somatostatin-, gastrin- and serotonin-immunoreactive cells in the fundus and pylorus of the rat stomach was examined by immunohistochemistry. The animals were killed by decapitation at 4 and 16 weeks of age (5 control rats and 5 hypertensive rats). Endocrine cells generally increase in number in hypertensive rats as compared to control rats. However, the detailed responses of endocrine cells to hypertension depend on the cell type, region of gastric mucosa and age of animals. The present results suggest that hypertension has an influence on the intrinsic regulatory system by endocrine cells control in the rat stomach.
