EFFECT OF INTENSIVE NERVOUS STIMULATION ON THE FINE STRUCTURE OF THE ADENOHYPOPHYSIS AND ITS TARGET ORGANS

Abstract

ABSTRACT Female white rats were exposed to periodic, complex and intensive nervous stimulation for 9 months. The electron microscopic examination of the adenohypophysis, adrenal cortex, thyroid gland and ovaries provided ultrastructural evidences of markedly increased hormone producing activity as compared with the controls. These findings confirm the previous results of the authors regarding the effect of their specially designed intensive periodic stressful stimulation on the function of the endocrine system, i. e. an increase in the activity of all the endocrine glands examined (Árvay 1964, 1970).
