The effects of insulin on sodium and potassium metabolism have been well known for many years; clinical observation and laboratory experience showed different results about the insulin effect on the sodium-potassium pump. Moreover, studies about the insulin effect on the sodium-potassium cotransport are not available. Therefore, the effects of insulin on Na+,K+ pump and Na+,K+ cotransport were evaluated. Results show that insulin inhibits Na+,K+ pump, while Na+,K+ cotransport is markedly activated. The possible link between pathogenesis of arterial hypertension in hyperinsulinemic subjects and present data is examined.

Abstract
The effects of insulin on sodium and potassium metabolism have been well known for many years; clinical observation and laboratory experience showed different results about the insulin effect on the sodium-potassium pump. Moreover, studies about the insulin effect on the sodium-potassium cotransport are not available. Therefore, the effects of insulin on Na+,K+ pump and Na+,K+ cotransport were evaluated. Results show that insulin inhibits Na+,K+ pump, while Na+,K+ cotransport is markedly activated. The possible link between pathogenesis of arterial hypertension in hyperinsulinemic subjects and present data is examined.File in questo prodotto:
