We aimed to examine trichotillomania (TTM), a rarely seen disorder, and N-acetylcysteine (NAC), an agent used as a treatment option, in the light of literature in the present study. Trichotillomania is the compulsive urge to pull out one’s own hair persistently and leading to noticeable hair loss. Contrary to what is expected, it is a more frequently detected disorder characterized by compulsiv...

Oxidative stress may play a role in chronic obstructive pulmonary disease (COPD) exacerbations. There is heterogeneity in the literature with regard to the impact of antioxidant therapy on COPD exacerbation frequency. Clinical trials of N-acetylcysteine in COPD were identified in unrestricted searches of MEDLINE, CINAHL, International Pharmaceutical Abstracts and the Cochrane Register. Randomiz...

OBJECTIVE To examine the combined effect of hyperbaric oxygen and N-acetylcysteine, a well-studied antioxidant, on fibroblast proliferation and production of 3 specific growth factors: basic fibroblast growth factor, vascular endothelial growth factor, and transforming growth factor beta1. DESIGN In vitro study. SUBJECTS None. INTERVENTIONS Human dermal fibroblasts were propagated in seru...

EVALUATION OF THE PROTECTIVE ROLE HYDROALCOHOLIC EXTRACT GINGER AND N-ACETYLCYSTEINE ON GENETIC DISORDER CAUSED BY SODIUM AZIDE HUMAN BLOOD LYMPHOCYTES MICRONUCLEUS METHOD

Cardiac remodeling was shown to be associated with reduced gap junction expression after myocardial infarction. A reduction in gap junctional proteins between myocytes may trigger ventricular arrhythmia. Therefore, we investigated whether N-acetylcysteine exerted antiarrhythmic effect by preserving connexin43 expression in postinfarcted rats, focusing on cAMP downstream molecules such as protei...

BACKGROUND N-Acetylcysteine has been shown to protect against contrast nephropathy, although the mechanisms underlying such an effect are unclear. Surprisingly, studies have shown that post-radiocontrast renal function actually improves in chronic renal failure patients receiving N-acetylcysteine. However, there have been no studies investigating the cause of this improvement. METHODS In a do...

Cocaine produces a persistent reduction in cystine– glutamate exchange via system xc in the nucleus accumbens that may contribute to pathological glutamate signaling linked to addiction. System xc influences glutamate neurotransmission by maintaining basal, extracellular glutamate in the nucleus accumbens, which, in turn, shapes synaptic activity by stimulating group II metabotropic glutamate a...

Cocaine produces a persistent reduction in cystine-glutamate exchange via system x(c)- in the nucleus accumbens that may contribute to pathological glutamate signaling linked to addiction. System x(c)- influences glutamate neurotransmission by maintaining basal, extracellular glutamate in the nucleus accumbens, which, in turn, shapes synaptic activity by stimulating group II metabotropic glutam...

OBJECTIVE Oxidative stress contributes to myocardial ischemia-reperfusion injury. We hypothesized that administration of the antioxidant N-acetylcysteine would have beneficial effects on myocardial function after cardiopulmonary bypass and cardioplegic arrest. METHODS Anesthetized dogs (n = 18) were instrumented with myocardial ultrasonic crystals and a left ventricular micromanometer. Systol...

Context Trichotillomania is characterized by repetitive hair pulling that causes noticeable hair loss. Data on the pharmacologic treatment of trichotillomania are limited to conflicting studies of serotonergic medications. N-acetylcysteine, an amino acid, seems to restore the extracellular glutamate concentration in the nucleus accumbens and, therefore, offers promise in the reduction of compul...
