Abstract

The present study shows that there is a circadian variation in the excretion of urinary kinin, kallikrein and prostaglandin E (PGE) as well as urine flow, urinary sodium excretion and urinary potassium excretion in recumbent healthy volunteers. The present data, that the acrophase of urinary kallikrein excretion was 1.5 hr later than that of plasma aldosterone concentration (PAC) and that a significant positive correlation was found in circadian variations between urinary kallikrein and PAC, suggest that the circadian variation of urinary kallikrein excretion may be regulated by aldosterone. The pattern of circadian variation of average urinary kinin excretion coincided with those of average urine flow, urinary sodium excretion and urinary PGE excretion, suggesting that renal kinin and PGE may be involved in the regulation of water-sodium excretion. The present data that the phase of circadian variation of urinary kinin was delayed from that of urinary kallikrein and that there was a mirror image between the circadian variation in urinary kinin and kallikrein suggest that there may be a feedback mechanism in renal kallikrein-kinin system.
