Abstract:
The effects of manganese on selenium content and glutathione peroxidaseactivity in blood and myocardium, and on selenium excretion in growing ratswere studied to ferret out the interaction of the two essential trace elements.Manganese dichloride (40mg/kg of MnCl2.4H2O) was administered daily to a group of 17 rats for 35 days intraperitoneally. An obvious increase in manganese content in serum and myocardium was induced. However, selenium levels in the two tissues of manganese-treated rats were significantly lower than the controls. From the 14th day on, glutathione peroxidase activities in whole blood of manganese-treated rats were below the controls, and on the 35th day, the activities of the selenium-containing enzyme in blood and myocardium were reduced by 29.33% (P
