[Effect of ascorbic acid on the renal transport of endogenous nitrates and nitrites in humans].

Effect of ascorbic acid on the renal excretion of endogenous nitrates and nitrites under aqueous-salt load was studied in practically healthy females. The administration of ascorbic acid in a dose of 10 mg/kg body weight under these conditions favored a decrease in the renal excretion of endogenous nitrates due to modulation of their renal clearance mechanism.
