Oxidoreductase in rats intoxicated with cadmium

There are a lot of literature data concerning the toxicity of cadmium on liver and kidney. The present work is concerning with the investigation of the effect of two plant extracts: Alloe and Allium sativum and an alcoholic Propolis extract on the behavior of the antioxidant systems. There were studied especially the activity of three enzymes: catalase, methaemoglobine reductase and superoxid dismutase consecutive an installed oxidative stress after cadmium administration in single doze. The changes which appear in the protection enzyme's activity are different in the red blood cells and in liver. The natural extracts had a different influence on the enzymes activity. The alcoholic propolis extract was more efficient on catalase and superoxid dismutase activities in comparison with the Allium sativum extract. The last one had an important role in the activity of superoxid dismutase.
