Summary
Simultaneous occurrence of hyperglycaemia (up to 300 mg/100 ml) and hyperinsulinaemia (up to 1200 μU/ml) was evident in the fed state in genetically diabetic KK mice, indicating insulin resistance. The hyperinsulinaemia was enhanced by α-adrenergic blockade and alleviated by B-blockade. Epinephrine-induced hyperglycaemia and isoproterenol-induced hyperinsulinaemia, both of which could be blocked by β-adrenergic antagonists, were more marked in KK mice than in ICR mice. A possible significance of adrenergic mechanisms is discussed with respect to the aetiology of the metabolic disturbances characteristic of KK mice.
