To assess the role of the central nervous system (CNS) in carbohydrate metabolism in diabetes, neostigmine was injected into the third cerebral ventricle in fed rats with streptozotocin (STZ; 80 mg/kg)-induced diabetes under pentobarbital sodium anesthesia. Changes in hepatic venous plasma glucose concentrations were monitored. Neostigmine injection caused no significant changes in the hepatic venous plasma glucose concentration in untreated diabetic rats, whereas the glucose level increased significantly in insulin-treated diabetic rats similarly to the changes in normal control animals. In diabetic rats, the plasma levels of glucagon, epinephrine, and norepinephrine were increased significantly by neostigmine. After various doses (35-80 mg/kg) were given to rats, it was found that the higher the STZ dose, the lower was the hepatic glycogen content and the smaller was the glycemic response to neostigmine. Our results indicate that, in severe diabetes, CNS stimulation with neostigmine fails to increase hepatic glucose output, because glycogen stores are nearly exhausted and gluconeogenesis is already maximal.
