흰쥐 hepatocyte에서 알파 및 베타 아드레날린 수용체의 자극에 의한 글리코겐분해에 있어서 칼슘과 니페디핀의 작용

Effects of calcium and calcium antagonist nifedipine on the glycogenolysis induced by the stimulation of alpha- and beta-adrenergic receptors in rat hepatocytes

The effects of calcium and calcium antagonist, nifedipine on the adrenergic receptor- stimulated glycogenolysis were investigated in isolated rat hepatocytes. The hepatic glycogenolysis induced by alpha-adrenergic receptor stimulation depended on calcium ions, and beta-adrenergic activation was unrelated to calcium ions. Nifedipine decreased the alpha-adrenergic agonist-induced glucose release significantly and the decrease was depended on calcium ions. The glucose release induced by beta-adrenergic agonist was not inhibited by nifedipine.
