Relaxin improves blood pressure and fetal growth restriction in a murine model of nitric oxide synthase inhibitor-induced hypertensive disorders of pregnancy

Role of L-NAME, a nitric oxide synthase inhibitor, in the improvement of morphine-induced amnesia induced by nicotine

Introduction: Drugs of abuse such as nicotine and morphine used systemically by addicts produce their effects via the mesolimbic dopaminergic pathway. Furthermore, evidence indicates that some behavioral effects of nicotine and morphine are mediated by nitric oxide (NO). Based on these observations, the aim of the present study was to investigate the effects of intra-nucleus accumbens (NAc) ...

Inducible nitric oxide synthase and blood pressure.

In the present studies, the influence of inducible nitric oxide synthase (NOS) inhibition with aminoguanidine on renal function and blood pressure was examined in rats. Intravenous aminoguanidine infusion (60 mg x kg-1 x hr-1) for 40 minutes to anesthetized Sprague-Dawley rats (n=7) resulted in no significant changes in mean arterial pressure or renal cortical blood flow, while medullary blood ...

Contribution of Nitric Oxide Synthase (NOS) Activity in Blood-Brain Barrier Disruption and Edema after Acute Ischemia/ Reperfusion in Aortic Coarctation-Induced Hypertensive Rats

Background: Nitric oxide synthase (NOS) activity is increased during hypertension and cerebral ischemia. NOS inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (BBB) disruption and cerebral edema formation during stroke in acute hypertension. Here, we investigated the role of NOS inhibition in progression of edema formation and BBB d...

Inhibition of nitric oxide synthase activity improves focal cerebral damage induced by cerebral ischemia/reperfusion in normotensive rats

Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...
