[The reaction of anterior hypothalamic nuclei and of the endocrine glands to the administration of staphylococcal peptidoglycan]. / Reaktsiia iader perednego gipotalamusa i éndokrinnykh zhelez na vvedenie stafilokokkovogo peptidoglikana.

The results of investigation of the influence of Staphylococcus peptidoglycan on supraoptic (SON) and paraventricular (PVN) hypothalamic nuclei, adrenal and thyroid glands of CBA mice was studied. Alterations in the SON and PVN secretory cells were found. The percentage of neurocytes that actively synthesize and secrete the Gomori [correction of Homory]-positive substance increased. Biosynthetic functions and secretion of the hormone was enhanced. In adrenal glands, alterations were found only in the bundled zone.

Ultrastructural changes in certain types of adenocytes of old rats, guinea pigs, rabbits and dogs are characterized by specific peculiarities. However, the direction of these changes mainly coincides. The somatotropic function of rats, guinea pigs and rabbits is suppressed, lactotrophic and corticotrophic cells being activated with aging. The phenomenon of the overstrain of gonadotrophic and thyrotrophic cells is registered. Dystrophic changes in the peripheral glands are observed.
