Regulation of kallikrein and renin release by the isolated perfused rat kidney.

Abstract

Rat kidneys perfused in vitro released kallikrein in urine, and renin and kallikrein in the perfusate. The kallikrein was characterized by its kininogenase activity and released bradykinin from bovine and dog substrates. Inactive trypsin activatable kallikrein was present in both perfusate and urine. Kallikrein secretion in urine was influenced by changes… (More)
