Effect of some indole derivatives on xenobiotic metabolism and xenobiotic-induced toxicity in cultured rat liver slices.
1999
In this study the effect of some indole derivatives on xenobiotic metabolizing enzymes and xenobiotic-induced toxicity has been examined in cultured precision-cut liver slices from male Sprague-Dawley rats. While treatment of rat liver slices for 72 hours with 2-200 microM of either indole-3-carbinol (I3C) or indole-3-acetonitrile (3-ICN) had little effect on cytochrome P-450 (CYP)-dependent enzyme activities, enzyme induction was observed after in vivo administration of I3C. The treatment of rat liver slices with 50 microM 3,3'-diindolylmethane (DIM; a dimer derived from I3C under acidic conditions) for 72 hours resulted in a marked induction of CYP-dependent enzyme activities. DIM appears…
Potential of the EPA/DHA 6/1 formulation to prevent endothelial dysfunction and cardiopulmonary remodeling in pulmonary arterial hypertension in rats
2016
Pulmonary arterial hypertension (PAH) is characterized by remodeling of the small pulmonary arteries leading to a progressive increase in pulmonary vascular resistance and right ventricular failure. Pulmonary endothelial dysfunction, inflammation and oxidative stress promote the development of pulmonary hypertension. Omega-3 polyunsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acids (DHA) have been shown to protect the cardiovascular system and reduce inflammation and oxidative stress. The present study evaluate the potential of EPA:DHA 6:1 to prevent monocrotaline-induced PAH in rats. EPA:DHA 6:1 treatment (500 mg/kg/d, p.o) prevented the MCT-induced mean pul…
