Current evidence suggests that hyperactivity of the sympathetic nervous system, and endothelial dysfunction are important factors in the development and maintenance of hypertension. Under normal conditions the endothelial mediator nitric oxide (NO) negatively modulates the activity of the norepinephrine portion of sympathetic neurotransmission, thereby placing a “brake” on the vasoconstrictor a...

  Objective- Mechanisms that decrease oxidative stress and enhance peritoneal fibrinolysis reduce adhesions. N-acetyl-L-cysteine (NAC) is an antioxidant whose effect on peritoneal fibrinolysis in large animal model has not been established. The aims of this study were to investigate the ability of NAC to decreased adhesion in stablished model of serosal trauma in sheep. Design- Expe...

t is known that ischemia reperfusion causes remote organ injury as well as local injury. The aim of this study was to investigate whether N-acetylcysteine has a protective effect against testicular injury after skeletal muscle ischemia reperfusion. Twenty male Wistar rats were allocated to two groups: ischemia reperfusion (control group) and ischemia reperfusion + N-acetylcysteine (treatment gr...

BACKGROUND Patients admitted to the emergency room with renal impairment and undergoing a contrast computed tomography (CT) are at high risk of developing contrast nephropathy as emergency precludes sufficient hydration prior to contrast use. The value of an ultra-high dose of intravenous N-acetylcysteine in this setting is unknown. METHODS From 2008 to 2010, we randomized 120 consecutive pat...

The aim of this study was to evaluate the effect of oral N-acetylcysteine in the prevention of re-hospitalisation for chronic obstructive pulmonary disease (COPD) exacerbations. Using the PHARmacoMOrbidity linkage (PHARMO) system the authors included all patients aged > or = 55 yrs who had been dispensed medication, labelled for respiratory indications (anatomical therapeutic chemical (ATC) cla...

PURPOSE OF REVIEW Acetaminophen poisoning accounts for a disproportionate percentage of all toxic ingestions, and can be life-threatening. This article reviews the mechanism and presentation of acetaminophen toxicity, as well as its treatment, including current thinking and treatment recommendations. RECENT FINDINGS N-acetylcysteine acts to detoxify acetaminophen in several ways, but primaril...

Previous experiments have shown that, following experimental fluid-percussion brain injury, cyclo-oxygenase-dependent formation of oxygen radicals prevents arteriolar vasoconstriction in response to hyperventilation. The oxygen radical scavengers superoxide dismutase and catalase restore normal reactivity; however, they are not routinely available for clinical use. The present study tested whet...

BACKGROUND Contrast-induced acute kidney injury (CI-AKI) is a serious complication of procedures requiring contrast media associated with rising costs, prolonged hospitalization, and increased mortality. The aim of this study was to assess whether prophylactic administration of standard dosages of intravenous N-acetylcysteine or ascorbic acid reduce the incidence of CI-AKI in patients with chro...

Idiopathic pulmonary fibrosis (IPF) is still a non-curable disease. The suggested therapy consists of Pirfenidone combined with other drugs like azathioprine, and acetylcysteine. The New England Journal of Medicine published a new study that goes against the common use of N-acetylcysteine (NAC) to treat IPF patient. There are other studies that went in favor of N-acetylcysteine. The present stu...
