001) higher MDA levels compared to that of the control group. However, endosulfan-treated selleck screening library groups receiving supplementation

of vit C, vit E or vit C+vit E had a significantly lower MDA levels compared to that of the group treated with endosulfan alone (figuer 1A). There was no significant difference among the testestrone of the control group, endosulfan-treated group, and endosulfan-treated group supplemented with vit C, vit E, or vita C+vit E (figure 1B). Group treated with endosulfan alone had a significantly (P<0.001) higher LDH Inhibitors,research,lifescience,medical levels compared to that of the control group. However, endosulfan-treated groups receiving supplementation of vit E or vit C+vit E had a significantly lower LDH levels compared to that of the group treated with endosulfan alone (figure 1C). Figure 1: Concentrations (mean±SEM, n=10) of Malondialdehyde (MDA) (A), serum testosterone (B), serum Inhibitors,research,lifescience,medical lactate dehydrogenase (LDH) levels (C) in the control rats and rats treated with endosulfan (Endo), endosulfan+vitamin C (vit Inhibitors,research,lifescience,medical C), edosulfan+vitamin E (vit ... Discussion Exposure to pesticides could cause male infertility by causing a significant

decrease in sperm quality and quantity.27 The results of the present study clearly indicate that endosulfan at a daily dose of 10 mg/kg significantly reduces the quality and quantity of sperm production. The result also shows the protective role of vitamin E and C on endosulfan–induced sperm Axitinib toxicity by decreasing lipid peroxidation, as shown by biochemical examination and further proved by improvements in qualitative and quantitative Inhibitors,research,lifescience,medical sperm parameters in vitamin-treated rats compared to endosulfan treated ones. Several studies have suggested that lipid peroxidation is involved in endosulfan toxicity.7,8

In this study, oral administration of endosulfan at 1/8 of the LD50,28 for 10 days increased MDA levels, as a marker of lipid per oxidation, in the testis. Lipid peroxidation of membrane polyunsaturated fatty acids disrupts the membrane integrity Inhibitors,research,lifescience,medical and results in the leakage Cilengitide of cellular enzyme into the systemic circulation.29 The increase in the level of LDH observed in the endosulfan-treated rats may be attributed to the excessive lipid peroxidation in the cell membrane that might have caused cell membrane damage. Plasma membranes of the sperms have a high content of polyunsaturated fatty acid; hence, they are highly sensitive to oxidative stress and lipid peroxidation.30 Lipid peroxidation has been shown to be associated with reduction in sperm mobility, viability and count.31 In this study, as might be expected, enhancement of lipid peroxidation by endosulfan is accompanied by a noticeable decrease in sperm viability, motility and DSP. Our data confirm the findings of other studies which reported that endosulfan administration induced decreases in the sperm parameters.
