Cardiac output in conscious one-clip, two-kidney renovascular hypertensive rats.
Cardiac output and arterial pressure in the conscious state were observed in one-clip, two-kidney renovascular hypertensive rats with a chronically implanted electromagnetic flow probe and an arterial cannula. Normal Wistar rats were used as controls. At rest, cardiac output per body weight did not show any difference between hypertensive rats and normal controls. This kind of experimental hype...
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 کاملA kallikrein-like enzyme in blood vessels of one-kidney, one clip hypertensive rats.
Active and inactive kallikrein or a kallikrein-like enzyme are found in the aorta, vena cava, and tail artery and veins of the rat. We studied the concentration of vascular kininogenase in rats with one-kidney, one clip renovascular hypertension and in unilaterally nephrectomized normotensive rats. Six weeks after surgery, active and total vascular kininogenase activity (active plus trypsin-act...
متن کاملImpaired 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 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...
