| Popis: | Water-electrolyte balance, plasma renin activity and urinary catecholamine excretion were studied for a period of 10 weeks after clipping the renal artery in the rat. Two groups of rats were examined; in Group I, a silver clip was applied on the left renal artery leaving the contralateral kidney untouched; in Group II, both renal arteries were clipped. Neither water-salt retention nor the increase in the activity of the renin-angiotensin system or in the neural tone seem to be essential in the development of high arterial pressure after renal ischemia. All these factors would seem to be secondary mechanisms the contribution of which would depend on the experimental model or the hypertensive period under consideration. |
