[Effect of chronic stimulation of the emotionogenic zones of the hypothalamus on the status of carbohydrate metabolism in the rabbit].

In chronic experiments on rabbits receiving for 3 months low doses of cholesterol (60 mg per 1 kg of body weight daily), a repeated prolonged (2 h daily) intermittent stimulation of negative and positive emotive zones of the hypothalamus through implanted electrodes (eliciting avoidance and self-stimulation reactions correspondingly),--resulted in uniform disturbances of carbohydrate metabolism. There was a significant reduction of glucose tolerance in comparison with the control group of rabbits with implanted electrodes, as well as a gradual development of a slight, but stable neurogenic hyperglycemia. Simultaneously, in both experimental rabbits groups there were an equal increase of alimentary hypercholesterolemia and a development of persistent neurogenic arterial hypertension.
