Chronic ethanol consumption is associated with an increased prevalence of hypertension. The mechanisms of this form of hypertension are unknown. Rats fed ethanol for 2 days develop a tolerance to the acute vasoconstrictive effects of ethanol that is believed to be endothelium dependent. We investigated the effects of acute and chronic ethanol exposure on agonist-stimulated nitric oxide synthase...

Endothelial nitric oxide synthase gene polymorphism (Glu298Asp) and development of Title: pre-eclampsia: a nested case-control study and a meta-analysis

BACKGROUND AND PURPOSE Nitric oxide has been implicated as a mediator of glutamate excitotoxicity in primary neuronal cultures. METHODS A number of indicators of brain nitric oxide production (nitric and cyclic guanosine monophosphate [cGMP] concentrations and nitric oxide synthase activity) were examined after bilateral carotid ligation and right middle cerebral artery occlusion in adult rat...

BACKGROUND Parkinson's disease (PD) is the second most common progressive neurodegenerative disorder. The degeneration of the nigro-striatal pathway has been linked with the inflammatory process accompanied by the robust up-regulation of the nitric oxide synthase (NOS) and production of the neurotoxic level of nitric oxide (NO). One of the therapeutic strategies of PD is based on the reduction ...

BACKGROUND Peripheral neuropathy is a frequent and major complication of diabetes. METHODS AND RESULTS Severe peripheral neuropathy developed in type II diabetic mice, characterized by significant slowing of motor and sensory nerve conduction velocities. Rosuvastatin restored nerve vascularity, including vessel size, and nerve function also recovered to the levels of nondiabetic mice. Neurona...

PURPOSE We attempted to determine whether oral L-arginine, the substrate for nitric oxide synthase, increases nitric oxide synthase activity and cyclic guanosine monophosphate (cGMP) levels in the urine from interstitial cystitis patients. Nitric oxide and cGMP are decreased in urine from interstitial cystitis patients and both induce smooth muscle relaxation and immunological responses. Increa...
