BLOOD SUGAR RECOVERY FROM INSULIN HYPOGLYCEMIA AFTER SECTION OF THE SPLANCHNIC NERVES

Abstract

After section of the splanchnic nerves in cats 2 units of insulin per kg. always produced shock, usually produced convulsions. Blood sugar detns. corroborate this in the sense that the splanchnics carry the impulses for prevention of excessive lowering of the blood sugar (emergency action). In the animals in which the emergency mechanism had been abolished a spontaneous restitution of blood sugar to normal values took place. Removal of the 2d and 3d lumbar sympathetic ganglia did not produce unusual reactions to insulin. The authors'' previous exps. on adrenal inactivation by various methods and in various spp. are discussed. In a total of 40 exps. showing definite hypoglycemic symptoms blood sugar recovery took place.
