title: The effects of kininase II inhibition by SQ 14225 on kidney kallikrein-kinin and prostaglandin systems in conscious dogs.
abstract: The novel kininase II inhibitor SQ 14225 was intravenously administered to normal conscious dogs at the dose of 0.1 mg/kg. Urine kinin excretion increased from 14 +/- 6 ng/h to 163 +/- 18 ng/h. Separation by column chromatography showed that the increased urine kinin excretion was due to increased excretion of bradykinin. The enhanced urinary kinin excretion was associated by increased sodium (70%) and decreased kallikrein (27%) excretion. Urine volume and urinary prostaglandin excretion were not significantly affected by SQ 14225 treatment.
