Abstract

The aim of this study has been to see whether acute variations in the proportions of circulating active and inactive renin in normal subjects were related to concurrent changes in the excretion of urinary kallikrein. Hydrochlorothiazide (50 mg/day) was given to 6 normal volunteers for 6 days; another group of 6 normal subjects received spironolactone (300 mg/day) for 6 days whereas synthetic aldosterone (0.5 mg/day) was administered i.m. for three days to 3 normal subjects. Both diuretics induced a sharp rise in active and total renin and a significant transient decrease in inactive renin so that the active: total renin proportion significantly increased. Urinary kallikrein excretion did not significantly change in either group. Parenteral administration of aldosterone induced a striking fall in all renin components without changing the proportions of active and inactive renin whereas urinary kallikrein excretion increased. These results indicate that changes in active: total renin proportions can occur without parallel variations in urinary kallikrein excretion. The latter cannot be used, therefore, as a reliable index of the possible role of renal kallikrein as activator in-vivo of inactive renin in man.
