[Role of the hypothalamus in the formation of antitumor resistance].
The development of Brown-Pearce tumor in rabbits is accompanied with regular changes in the functional activity of the hypothalamic zone, related close enough with the regulation of adrenal cortex functions and immunological processes. In electrostimulation of the posterior hypothalamus median zones an accelerated resorption of the tumor, inoculated subcutaneously, was noted. The destruction of the posteromedian hypothalamic structures resulted in a sharp fall of corticosteroids level in the organism and a decreased intensity of generally persistant immunity to repeat inoculations of Brown-Pearce tumor. Thus, the fact of the immunocompetent system being ready to realize protective reactions for preservation of the genetic constancy of the organism is conditioned by the hypothalamo-hypophyseal-adrenal system functional activity.
