[Effect of a lesion of the hypothalamic nuclei on the morphofunctional state of the hypothalamo-hypophyseal system and the development of experimental atherosclerosis].
Injury of individual nuclei of the anterior and the middle portions of the hypothalamus in rabbits by electrocoagulation through the preliminarily implanted electrodes was accompanied by the change in the morpho-functional condition of the hypothalamo-hypophysial neurosecretory system (HHNS). The nearer the focus of injury to the region of the supraoptic nuclei -- the greater the functional activity of the HHNS. In combining the injuries of individual hypothalamic nuclei with the atherogenic diet there occurred marked morpho-functional changes both in the HHNS and in the adrenal glands; as to animals with experimental atherosclerosis, it acquired under these conditions a more severe form than in the animals on the atherogenic diet alone. Results of investigations pointed to the presence of a close association of the genesis of the atherosclerotic process with the neurogenic factors.
