To address these issues, we analyzed the combined circulatory and metabolic consequences of inhibiting the nNOS both at rest and during functional activation in the rat anesthetized with alpha-chloralose.

The cerebrovascular coupling under neuronal nitric oxide synthase (nNOS) inhibition was investigated in alpha-chloralose anesthetized rats.

We examined the effect of 7-nitroindazole (7NI), a reportedly relatively specific inhibitor of the neuronal isoform of nitric oxide synthase (nNOS), on mean arterial blood pressure and on cerebral blood flow in rats under three different types of anaesthesia: urethane-chloralose, halothane, or urethane preceded by induction of anaesthesia with halothane.

In alpha-chloralose- and urethane-anesthetized rats, microinjection of N (G)-monomethyl-L-arginine (L-NMMA), a NO antagonist, into the PVN produced a dose-dependent increase in RSND, blood pressure, and heart rate.

We evaluated the effects of superfusing 1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1-one (ODQ), eNOS null (B) an inhibitor of soluble guanylyl cyclase, and 7-nitroindazole sodium (7-NI), a selective neuronal nitric oxide synthase (nNOS) inhibitor, on the acetylcholine (ACh) response in endothelial NOS (eNOS) null mice.
Pial arteriolar diameter was measured by intravital microscopy through a closed cranial window under alpha-chloralose anesthesia.

We examined the effect of type I nitric oxide synthase (neuronal isoform of NOS, nNOS) inhibition on the temporal profile of the cortical blood flow (CoBF) changes induced by a relatively long period (10 min) of whisker stimulation.
To address this issue, we used laser-Doppler flowmetry (LDF) to continuously monitor the CoBF in rats anesthetized with alpha-chloralose, in a control condition, and 30 and 60 min following 7-nitroindazole (25 mg/kg, i.p.).

We have demonstrated a decreased neuronal nitric oxide (NO) synthase (nNOS) message in the hypothalamus of rats with heart failure (HF).
In alpha-chloralose- and urethane-anesthetized rats, an inhibitor of NO synthase, N (G)-monomethyl-L-arginine (L-NMMA) microinjected into the PVN (50, 100, and 200 pmol in 50-200 nl) produced a dose-dependent increase in RSND, blood pressure, and heart rate in control and HF rats.

Diabetic rats were found to have significantly fewer nNOS positive cells in the PVN than in the control group (120 +/- 11 vs. 149 +/- 13, P < 0.05).
In alpha-chloralose- and urethane-anesthetized rats, an inhibitor of NO synthase, l-NMMA, microinjected into the PVN produced a dose-dependent increase in RSNA, mean arterial pressure (MAP), and heart rate (HR) in both control and diabetic rats.

The contribution of nitric oxide (NO) to the antinatriuresis and antidiuresis caused by low-level electrical stimulation of the renal sympathetic nerves (RNS) was investigated in rats anaesthetized with chloralose-urethane.
These data demonstrated that the renal nerve-mediated antinatriuresis and antidiuresis was dependent on the presence of NO, generated in part by nNOS.

The neuronal isoform of the enzyme nitric oxide synthase (nNOS) has been identified in the caudal ventrolateral medulla of the rat close to the location of cardiac vagal motoneurones.
In rats anaesthetised with a mixture of urethane (650 mg kg (-1)) and chloralose (50 mg kg (-1)) i.v., blood pressure and heart rate were monitored continuously and using stereotaxic coordinates the ventrolateral caudal brainstem within and around the nucleus ambiguus was systematically explored for sites producing a bradycardia of > 50 bpm, without a change in blood pressure, using D,L homocysteic acid (DLH, 0.2 M) microinjections (50 nl) from a glass micropipette.

All dogs were anesthetized with alpha-chloralose (100 mg/kg, iv).
