N-Acetylcysteine (NAC) is a well established thiol antioxidant which, after uptake, deacylation and conversion to glutathione functions as both a redox buffer and a reactive oxygen intermediate scavenger. We report here that NAC completely blocks activation induced death and associated DNA fragmentation of myelin basic protein (MBP) specific T cell hybridomas. Conversely, NAC had very little ef...

This study was designed to study the protective effects and mechanisms of N-acetylcysteine (NAC) in concanavalin A-induced hepatitis in mice. In this study, pretreatment with NAC ameliorated the histopathological changes and suppressed inflammatory cytokines in ConA-induced hepatitis. The expression of IL-2, IL-6, TNF-α, and IFN-γ was significantly reduced in the NAC-treated groups. NAC activat...

Oxidative stress is implicated as a factor that increases necrosis of skeletal muscles in Duchenne Muscular Dystrophy (DMD) and the dystrophic mdx mouse. Consequently, drugs that minimize oxidative stress are potential treatments for muscular dystrophy. This study examined the in vivo benefits to mdx mice of an antioxidant treatment with the cysteine precursor N-acetylcysteine (NAC), administer...

Monosodium glutamate (MSG) is a flavor enhancer, largely used in the food industry and it was reported to have excitotoxic effects. Higher amounts of MSG consumption have been related with increased risk of many diseases, including Chinese restaurant syndrome and metabolic syndromes in human. This study investigated the protective effects of N-acetylcysteine (NAC) on MSG-induced cytotoxicity in...

N-acetylcysteine (NAC) is a potent antioxidant that acts through regenerating glutathione stores and scavenging oxygen-free radicals. This study assesses the short-term effects of NAC in cadaveric kidney transplant (KT) recipients. A double blind, randomized, placebo controlled trial was designed and patients were randomly assigned to receive either NAC or placebo. Glutathione peroxidase (GPX) ...

Background: The development of methods to alleviate radiation-induced health effects is important for the practical use of radiation therapy and for understanding the molecular mechanisms mediating these effects. Here, we examined the protective capability of N-acetylcysteine (NAC) on life-shortening effects induced by continuous low dose-rate gamma-ray exposure in mice. Materials and Methods: ...

Objective Titanium dioxide (TiO2) is a white pigment which is used in paints, plastics, etc. It is reported to induce ‎oxidative stress and DNA damage. The N-acetylcysteine (NAC) was used to fight oxidative stress-induced ‎damage in various tissues. The aim of this study was to evaluate the toxic effects of TiO2 nanoparticles by oral ‎administration and the protective role of NAC on testes of a...

BACKGROUND Rhabdomyolysis-induced acute kidney injury (AKI) accounts for about 10 to 40% of all cases of AKI. It is known that N-acetylcysteine (NAC) is effective in various experimental renal injury models; however, little information is available about the rat model of glycerol-induced rhabdomyolysis. In this study, we hypothesize that NAC plays a renoprotective role via the anti-apoptotic pa...

Protective effects of N-acetylcysteine (NAC) on homocysteine (Hcy)-induced injury have been reported in vitro. However, it is not known whether NAC has a similar effect in Hcy-induced injury during embryonic development. In this study, we tested the hypothesis that exogenous NAC can attenuate Hcy-induced injury in chick embryos. Hcy-induced apoptosis and reduced embryo viability were effectivel...
