Effect of parathyroid hormone on renin secretion.

The ability of parathyroid hormone (PTH) to increase renin secretion was investigated in pentobarbital-anesthetized dogs. An intravenous infusion of bovine PTH 1-34, at the dose of 0.028 microgram/kg-1 min-1 increased renin secretion by 149% (501 +/- 105 to 1249 +/- 309 ng hr-1 min-1); renin secretion returned to control values during the recovery period. In order to determine whether PTH acted directly on the kidney to increase renin secretion, PTH was infused into the right renal artery at doses of 0.0014 to 0.0028 microgram/kg-1 min-1 and renin secretion from the right kidney was compared to that from the left (control) kidney. Renin secretion from the right (PTH-infused) kidney was not greater than control values for that kidney or different from the renin secretory rate of the left (control) kidney. In contrast, the excretion rates of both phosphate and sodium from the right kidney were greater than control values and from the excretion rates of the left kidney. These data suggest that PTH, while acting directly on the kidney to increase phosphate and sodium excretion, does not elevate renin secretion by a direct renal action.[1]
