Effect 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 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 کاملTwo-Kidney, One-Clip Hypertension in the Rat
Baroreflex function was studied in conscious early phase (<6 weeks) two-kidney, one-clip hypertensive rats before and 24 hours after surgical reversal of hypertension by removal of the constricting renal artery clip or after pharmacological reduction of blood pressure by an infusion of hydralazine or captopril. A normotensive sham-clipped group was included. Another group of two-kidney, one-cli...
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 کاملAntihypertensive effects of some new nitroxyalkyl 1,4-dihydropyridine derivatives in rat model of two-kidney, one-clip hypertension
Dihydropyridine calcium channel blockers consist one of the widely-used groups of drugs for the management of hypertension. In this study, antihypertensive effects of 5 newly synthesized derivatives of DHP was examined the in rat model of two-kidney, one-clip renal hypertension. The results showed that those compounds containing two nitroxy groups had less decreasing effect on MAP (Men Arterial...
