introduction: the fate of xenobiotics that is present, increasing day by day. the increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. methods: the present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by panax ginseng ...

resistance of the weanling rat to acetaminophen (ap ap)-induced hepatotoxicity is manifested with regard to a surge in apap-glutathione (osh) conjugate formation in the liver [allameh et al. mech aging dev 95(1997)71]. the present study was conducted to assess the role of this detoxification pathway in apapinduced lipid per6xidationin the liver. lipid peroxidation measured as thiobarbituric aci...

Age-associated changes in several antioxidative factors were studied in blood and liver from mice prone to accelerated senescence aged O.7 to 1.4 years and mice resistant to acce]erated senescence aged 1.0 to 2.1 years. In both strains, actiyities of hepatic glutathione peroxidase (GSH-Px) and glutathione-Stransferase (GST) decrefised significantly with age, and the actiyity of superoxide dismu...

Organosulfur compounds (OSCs) present in garlic and onion oil have been shown to inhibit chemical carcinogenesis. In this study, we compared the chemopreventive efficacy of five lipidand four water-soluble OSCs using the murine nuclear aberration assay. Administration of diallyl sulfide and 5-allyl cysteine p.o. at a dose of 200 mg/kg 3 h prior to i.p. 1,2-dimethylhydrazine (DMII) injection (20...

Fipronil toxicity and metabolism were studied in two insecticide-resistant, and one susceptible western corn rootworm (Diabrotica virgifera virgifera, LeConte) populations. Toxicity was evaluated by exposure to surface residues and by topical application. Surface residue bioassays indicated no differences in ®pronil susceptibility among the three populations. Topical bioassays were used to stud...

The present study was undertaken to evaluate the influence of butachlor, a widely used herbicide, on antioxidant enzyme system and lipid peroxidation formation in African cat fish (Clarias gariepinus). Fish were exposed to sub-lethal concentrations of butachlor 1, 2, 2.5 ppm and sacrificed 24hrs after treatment. A significant increase in malondialdehyde formation was observed in the liver, kidn...

This study investigated the role of antioxidant enzyme system following crude hydroethanolic extract of Moringa oleifera leaves (MO) in acute paracetamol (PCM) induced hepatotoxicity. Hydroethanolic extract (80%) of MO (200 mg/kg and 800 mg/kg; p.o) was pre-administered before a single oral dose of 3 g/kg PCM intoxication to male Sprague-Dawley rats. Pre-treatment of the extract was found to ha...

Currently several studies are being carried out on various properties of mesenchymal stem cells (MSCs)however there are a few investigations about drug metabolizing properties of these cells. The aim of thisstudy was to measure the key factors involved in drug metabolism in human bone marrow MSCs. For thispurpose, cellular glutathione (GSH), glutathione Stransferase (GSTs) and...
