Impaired renorenal reflexes in two-kidney, one clip hypertensive rats.
In normotensive rats, stimulation of renal mechanoreceptors by an increase in ureteral pressure results in a contralateral inhibitory renorenal reflex response with contralateral natriuresis. Similar effects are produced by stimulation of renal chemoreceptors by renal pelvic perfusion with 0.9 M NaCl. However, in spontaneously hypertensive rats the renorenal reflex responses to renal mechanorec...
متن کاملImpaired renorenal reflexes in spontaneously hypertensive rats.
In normotensive Sprague-Dawley rats stimulation of renal mechanoreceptors and chemoreceptors by increasing ureteral pressure and retrograde ureteropelvic perfusion with 0.9 M NaCl results in a contralateral inhibitory renorenal reflex response with contralateral diuresis and natriuresis. Since efferent renal nerve activity is increased in spontaneously hypertensive rats (SHR) and renal denervat...
متن کاملEffect of clonidine on blood pressure in chronic one-kidney, one-clip and two-kidney, one-clip hypertensive rats.
Oral administration of clonidine lowered the high blood pressure in two-kidney, one-clip hypertensive rats in chronic stage (three to four months), but not in one-kidney, one-clip hypertensive rats. This reduction of blood pressure was well correlated with decrease in plasma renin concentration, but not with decrease in urinary noradrenaline excretion. These results suggest that the reduction o...
متن کاملEffects of Low-dose Morphine on Nitric Oxide Concentration and Angiogenesis in Two-kidney One Clip Hypertensive Rats
Objective(s) We investigated the effects of low-dose morphine on nitric oxide (NO) and angiogenesis in two-kidney one clip hypertensive (2K1C) rats. Materials and Methods Male rats were divided into two groups: sham-clip operated and 2K1C. Each group subdivided into saline and morphine (3 mg/kg i.p. 8 weeks) groups. Blood pressure, heart rate, plasma renin activity (PRA), NO concentration an...
متن کاملImpaired renal blood flow autoregulation in two-kidney, one-clip hypertensive rats is caused by enhanced activity of nitric oxide.
Increases in renal perfusion pressure will induce shear stress-mediated nitric oxide (NO) release, which could oppose autoregulation of renal blood flow (RBF). Although cardiac, cerebral, and mesenteric autoregulation is enhanced during nitric oxide (NO) synthesis inhibition, this has not been reported for renal autoregulation of blood flow. In the present study, the lower limit and efficiency ...
