Herapeutic dose, PCM is converted by drug metabolizing enzymes to water-soluble metabolites and secreted within the urine [17, 18]. Saturated and excess PCM is oxidatively metabolized by hepatic cytochrome pBioMed Analysis InternationalI CV NCVH(a)(b)N CVCV I(c)(d)I CV CV(e)(f)Figure two: Microscopic observations of liver tissue pretreated with different concentrations of MEMC followed by treatment against PCMinduced liver injury: (a) normal, (b) section of liver tissue of three g/kg PCM-treated group (p.o.) showing enormous necrosis, haemorrhage, and inflammation, (c) section of 50 mg/kg of N-acetylcysteine liver tissue pretreated around the liver followed by PCM displaying preservation of regular hepatocytes, (d) section of pretreated 50 mg/kg MEMC liver tissue followed by PCM showing tissue necrosis and inflammation, (e) section of pretreated 250 mg/kg MEMC liver tissue followed by PCM showing mild inflammation, and (f) section of pretreated 500 mg/kg MEMC liver tissue followed by PCM displaying normal histology with mild inflammation (40x magnification). CV: central vein; N: necrosis; I: inflammation; H: haemorrhage.(CYP450) system to a toxic metabolite, namely, N-acetyl-pbenzoquinone imine (NAPQI) [19?1]. The NAPQI is commonly detoxified by a nonprotein thiol referred to as glutathione (GSH) with both oxidant scavenger and redox-regulation capacities [20]. GSH is a important antioxidant system and also a vital element of host defense which can be responsiblefor scavenging reactive free radicals produced via the metabolism method within the liver to stop cell injury [16, 22]. The toxic dose of PCM triggered the depletion of GSH resulting in accumulation of NAPQI which then covalently binds for the cysteinyl sulfhydryl groups of cellular proteins forming NAPQI-protein adducts [23, 24].
