Potassium and Related Disorders

Renal lymph concentrations of sodium and potassium were compared with those of arterial blood plasma before and during ACh induced decrease in medullary sodium concentration. It was found that L/P ratios of both sodium and potassium were unchanged following renal arterial infusion of ACh. These data yielded the conclusion that L/P ratios for sodium are largely due to renal cortical mechanisms and are independent of medullary interstitial fluid sodium concentration.
