Mitochondria play a central role in molecular events leading to tissue damage in ischemia. The present study examines the role of the alcoholic extract of T. chebula (TCE) pretreatment (50 mg/100 g body weight) to attenuate the isoproterenol (ISO) (20mg/100g body wt, sc) induced alterations on heart mitochondrial ultrastucture and function in experimental rats.
Drug Metabolism and Disposition: The Biological Fate of Chemicals
β-Naphthoflavone (BNF) is a synthetic flavone that selectively and potently induces CYP1A enzymes via aryl hydrocarbon receptor activation. Mechanism-based mathematical models of CYP1A enzyme induction were developed to predict the time course of enzyme induction and quantitatively evaluate the interrelationship between BNF plasma concentrations, hepatic CYP1A1 and CYP1A2 mRNA levels, and CYP1A enzyme activity in rats in vivo. Male Sprague-Dawley rats received a continuous intravenous infusion of vehicle or 1.5 or 6 mg · kg(-1) · h(-1) BNF for 6 h, with blood and liver sampling.
