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...

N-Acetylcysteine is a thiol antioxidant with expanding clinical importance. A sensitive, rapid method for determining reduced N-acetylcysteine (NAC) concentration in biological samples has been developed which uses a modified reversed-phase high-performance liquid chromatography (HPLC) technique in conjunction with the derivatizing agent N-(1-pyrenyl)maleimide (NPM). The NAC-NPM adduct was anal...

Investigators from NIH, Hyperion Biotechnology Inc., and Hospital for Sick Children studied the effect of oral N-acetylcysteine (NAC) on decreasing oxidative stress increasing physical endurance in individuals with ryanodine receptor 1-related myopathies (RYR1-RM).

BACKGROUND/AIMS Although increased oxidative stress plays a role in heart failure (HF)-induced skeletal myopathy, signaling pathways involved in muscle changes and the role of antioxidant agents have been poorly addressed. We evaluated the effects of N-acetylcysteine (NAC) on intracellular signaling pathways potentially modulated by oxidative stress in soleus muscle from HF rats. METHODS AND ...

N-isobutyrylcysteine (NIC), a new thiol compound that is not rapidly hydrolysed to give higher levels of free thiols in the body than N-acetylcysteine (NAC), was used to test if the effect of NAC on exacerbations in chronic bronchitis was an effect of the unhydrolysed thiol compound. Smokers or exsmokers with chronic bronchitis forced expiratory volume in one second (FEV1) >40% and reversibilit...

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...

N-acetylcysteine (NAC) a derivative of amino acid L-cysteine is currently used mainly as an antioxidant. Sulfhydryl group (–SH) within its molecule makes possible to directly scavenge reactive oxygen species (ROS). Indirect antioxidant action of NAC rely on augmentation of the level of reduced glutathione (GSH) – a major body’s antioxidant. Since oxidative stress takes a part in pathogenesis of...

Background: N-acetylcysteine (NAC) has been indicated against experimental seizures, but with relatively inconclusive results. This study was undertaken to evaluate whether NAC exerts a dose-dependent anticonvulsant effect and to determine NAC safe therapeutic dose range and its muscle-relaxant activity in both acute and chronic uses.Methods: Following intraperitoneal (i.p.) administration of N...
