The present study was designed to investigate the effects of vitamin E (vit E), selenium (Se) and vit E + Se against organophosphate (OP) toxicity in tissues' trace and major element levels and erythrocyte antioxidant enzyme activities of rats. Trace and major element concentrations in the tissues were measured by inductively coupled plasma-optical emission spectroscopy. Erythrocyte antioxidant enzyme activities were studied by using spectrophotometer. Antioxidant enzyme activities such as superoxide dismutase, glutathione peroxidase and catalase increased in the fenthion-treated groups (control) more than that of sham group subjects. Heart and pectoral muscle tissue Se and Zn concentrations in the control group were higher than sham group. However, jejunum, kidney, liver and pancreas Se and Zn concentrations in the control group were found to be lower than those in the sham group. The Mn concentrations in the all of the tissues were lower in the control group when compared with the sham group. Brain, heart, jejunum, kidney and pancreas Fe concentrations and heart, jejunum, liver, pectoral muscle and pancreas Cu concentrations were found to be lower in the control group. The treatment of vit E, Se and vit E + Se were increased bio-element levels in the many tissue. In conclusion, the results of the present study demonstrate that the tissue trace and major element concentrations and enzymatic antioxidant system were significantly affected OP toxicity. Furthermore, we have shown an association between bio-elements and antioxidant enzymes in OP toxicity. In addition, administration of vit E, Se and vit E + Se might regulate some trace and major element levels in the many tissues. (C) 2010 Elsevier Inc. All rights reserved.
