| Abstract: | Renal kallikrein and phospholipase activities were evaluated in a strain of spontaneously hypertensive rats developed by Dr. Bianchi in Milan (MHR). MHR showed lower than normal kallikrein and phospholipase activities before, at 3 weeks of age and following the development of hypertension. Kallikrein and phospholipase activities were directly correlated both in normotensive and spontenously hypertensive rats. The data suggest that MHR have a genetic defect in kallikrein and phospholipase activities, which may play a pathogenetic role in the development of high blood pressure. |
