Hypothalamus-hypophysical system of the rat females under conditions of the prolonged internal irradiation

Arcuate and suprachiasmatic hypothalamus nuclei, median eminence and adenohypothysis in female rats under prolonged inner irradiation conditions were studied by the electron-microscopic method. Changes in secretory neurocytes accumulation of secretory granules and neural terminals of median eminence, intensive formation of thyrotropin and prolactin secretion with productive hypothysis cells have been discovered. Develapment mechanisms of remote sequences of the ionizing radiation effect on the genital system of female rats are discussed
