Background: Role of nitric oxide (NO) in morphine-induced conditioned place preference (CPP) has already been proposed in the rat medial septum (MS), but no molecular evidence has been provided to clear this fact. Methods: Effects of intraseptal injections of L-arginine and/or NG-nitro-L-arginine methyl ester (L-NAME) on morphine place conditioning in Wistar rats were examined. Morphine (2.5-7....

background and objective: nitric oxide (no) plays a role in thermoregulation and growth of protozoa. this work aimed to add the molecule no in physiology of protozoa in contact with abused narcotic substances. materials and methods: a sedative drug, morphine, was infused into a cell chamber containing paramecia . the cell response to the drug was recorded promptly after drug infusion using a po...

The present study was designed to examine the role of nitric oxide (NO) in quinolinic acid (QUIN)-induced depletion of rat striatal nicotinamide adenine dinucleotide phosphate (NADPH) diaphorase and enkephalinergic neurons. Intrastriatal injection of QUIN produced a dose-dependent decrease in NADPH diaphorase and enkephalin positive cells, with cell loss being evident following the injection of...

Igelmann et al. report a novel metabolic cycle, which they name HTC, that converts NADH into the key antioxidant factor NADPH. The HTC is repressed by tumor suppressors p53 and RB, this determines whether oncogene-expressing cells undergo senescence (HTCoff) or malignant transformation (HTCon).

The effect of ellagic acid on oxidative stress and hypertension induced by Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME) was investigated. Male Sprague-Dawley rats were administrated with L-NAME (40 mg/kg/day) for five weeks. L-NAME induced high systolic blood pressure (SBP) and increased heart rate (HR), hindlimb vascular resistance (HVR) and oxidative stress. Concurrent treatment wi...
