Previous studies have suggested that (1) nitroglycerin causes vasodilatation by interacting with sulfhydryl groups in vascular smooth muscle, thereby activating guanylate cyclase and increasing the intracellular concentration of cyclic GMP, and (2) N-acetylcysteine, a source of sulfhydryl groups, potentiates the peripheral vasodilatory effect of nitroglycerin. This study was performed to explor...
background: cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. the aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats. methods...
N-Acetylcysteine (NAC) targets a diverse array of factors germane to the pathophysiology of multiple neuropsychiatric disorders including glutamatergic transmission, the antioxidant glutathione, neurotrophins, apoptosis, mitochondrial function, and inflammatory pathways. This review summarises the areas where the mechanisms of action of NAC overlap with known pathophysiological elements, and of...
The ability of transforming growth factor-beta1 (TGF-beta1) to induce epithelial-mesenchymal transition (EMT) in alveolar epithelial cells (AEC) in vitro and in vivo, together with the demonstration of EMT in biopsies of idiopathic pulmonary fibrosis (IPF) patients, suggests a role for TGF-beta1-induced EMT in disease pathogenesis. We investigated the effects of N-acetylcysteine (NAC) on TGF-be...
Adverse reactions to N-acetylcysteine are reported in 6% to 23% of patients who are administered the antidote for treatment of paracetamol poisoning.1 Because paracetamol is the most common pharmaceutical product taken in overdose in many countries, it is essential that attempts be made to prevent or minimize adverse effects caused by N-acetylcysteine. We congratulate Kerr et al2 on their attem...
Trichotillomania is considered a behavioral disorder and is characterized by the recurring habit of pulling one's hair, resulting in secondary alopecia. It affects 1% of the adult population, and 2 to 4.4% of psychiatric patients meet the diagnostic criteria. It can occur at any age and is more prevalent in adolescents and females. Its occurrence in childhood is not uncommon and tends to have a...
There are a limited number of Food and Drug Administration (FDA)-approved medications for the treatment of autism. Meanwhile, oxidative stress and neuroinflammation are supposed to play a causative role in autism. N-acetylcysteine may provide cystine, a precursor for glutathione (GSH), which is an important antioxidant factor in the brain. We here report a child with autism, whose symptoms were...
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 ab...
Skin Picking Disorder affects 4% of the general population, with serious quality of life impacts, and potentially life threatening complications. Standard psychoactive medications do not help most patients. Similarly, Mouse Ulcerative Dermatitis (skin lesions caused by excessive abnormal grooming behavior) is very common in widely used inbred strains of mice, and represents a serious animal wel...
Using data form a 14-day double-blind trial with 48 smokers randomized to either N-acetylcysteine (2400 mg) or placebo, we tested the effect of N-acetylcysteine on glutamate and gamma-aminobutyric acid concentrations in the dorsal anterior cingulate cortex and on smoking cessation. Smoking related behaviors and neurotransmitter concentrations in the dorsal anterior cingulate cortex were assesse...
