Effect of NG-monomethyl L-arginine on endothelium-dependent relaxation in arterioles of one-kidney, one clip hypertensive rats.
Dose-response curves to topically applied acetylcholine, bradykinin, and nitroprusside were obtained by intravital microscopy in arcading arterioles of the spinotrapezius muscle of control (n = 9) and one-kidney, one clip hypertensive (1K1C) rats (n = 11) of 4 weeks' duration before and during superfusion with the specific inhibitor of nitric oxide formation NG-monomethyl L-arginine (LNMMA) (10...
متن کاملImpairment of Endothelium-Dependent Relaxation in Chronic Two-Kidney, One Clip Hypertensive Rats
OBJECTIVES Hypertension is commonly associated with an endothelial dysfunction that may contribute to the rise in blood pressure. Little information has been available so far on the role of endothelium-derived nitric oxide(EDNO) in renin-dependent, 2-kidney, 1 clip(2KIC) hypertension. The present study was aimed to determine a role for EDNO in the development and maintenance of 2KIC hypertensio...
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 کاملEffect of NG-monomethyl-L-arginine on regional vascular resistance in rats.
This study investigated the effects of intravenous injection of the specific inhibitor of nitric oxide (NO) formation, NG-monomethyl-L-arginine (L-NMMA), on mean arterial pressure and regional vascular resistance in rats (n = 7). Regional vascular resistances of brain, heart, left kidney, intestine (jejunum), left testis and right testis were measured using radiolabelled microspheres before and...
