[Experimental assessment of exposure to the tobacco smoke and its effect on superoxide dismutase and glutathione peroxidase activities].

Abstract

Activities of two antioxidant enzymes, superoxide dismutase (SOD) and glutathione peroxidase (GPx) were determined in plasma of rats exposed to tobacco smoke (500, 1000 and 1500 mg CO/m3 air in 5 days) and to 1000 mg CO/m3 in 1, 2 and 3 weeks. When compared to controls, the SOD activity was decreased in the exposed animals, the lowest smoke dose gave the… (More)
