Abstract
This investigation was undertaken to study the reaction of paraventricular nuclei (PVN) subnuclei to insulin deficiency and to elevation of the blood glucose level under conditions of experimental alloxan diabetes. Experiments were carried out on 15 control and 15 experimental mature male Wistar rats. The state of the carbohydrate metabolism of the diabetic and control animals was judged by the blood glucose and radioimmune insulin levels. The results of these investigations show that both magnocellular and parvocellular neurons of PVN react to alloxan diabetes, which supports the hypothesis that PVN of the hypothalamus participates in the control of carbohydrate metabolism.
