Effects of omapatrilat on blood pressure and renal injury in L-NAME and L-NAME plus DOCA-treated rats.

BACKGROUND This study investigates the effects of chronic administration of omapatrilat (OMA) on blood pressure (BP), renal injury, and other variables in N(omega)-nitro-L-arginine methyl ester (L-NAME) hypertension and in the low-renin model produced by the simultaneous administration of L-NAME and deoxycorticosterone acetate (DOCA). METHODS The control, DOCA, L-NAME, L-NAME + DOCA, L-NAME +...

Renal injury in angiotensin II+L-NAME-induced hypertensive rats is independent of elevated blood pressure.

The balance between angiotensin II (ANG II) and nitric oxide plays an important role in renal function and is thought to contribute to the progression of renal injury in experimental hypertension. In the present study, we investigated the extent of blood pressure (BP)-dependent and BP-independent pathways of renal injury following 2 wk of hypertension produced by intravenous infusion of ANG II ...

Effects of L-Arginine and L-NAME on Duodenal Histologic Parameters in Female Wistar Rats

Introduction: Nitric oxide (NO), as a free radical, involves in several physiologic functions in GI tract such as nerve impulse transmission and vascular tonicity regulation. Nitric oxide synthase (NOS) is the enzyme for the production of NO from L-Arginine which in turn inhibits by L-NGNitroarginine Methyl Ester (L-NAME). In the current work, we aimed to evaluate morphometric analysis of...

Effects of l-NAME on cerebral metabolic, vasopressin, oxytocin, and blood pressure responses in hemorrhaged rats.

N G-nitro-l-arginine methyl ester (l-NAME; 250 μg/5 μl), an inhibitor of NO synthase, or the vehicle artificial cerebrospinal fluid (aCSF; 5 μl) was administered intracerebroventricularly to conscious rats hemorrhaged (0.7 ml/min) to a 20% volume depletion. Hypotension was maximal 5 min after hemorrhage ended, with compensatory recovery to basal levels 20 min later, regardless of drug treatment...

The effect of L-arginine and L-NAME on intravenous self-administration of morphine in rats

  The involvement of nitric oxide (NO) in the reinforcing properties of opiate reward was studied by examining the effect of a NO precursor (L-arginine) and a NO synthase inhibitor (L-NAME) on the rate of intravenous self-administration of morphine. This experiment was investigated in male albino Sprague Dawley rats (300 ± 50 g). At doses of 5 and 10 mg/kg (i.p.), L-arginine decreased morphine ...
