Mercury intoxication has been associated with male reproductive toxicity in experimental animals and mercury may have the potential to produce adverse effects on fertility in men. Vitamin E may protect against toxic effects of mercury in the liver and other tissues. To investigate the protective role of vitamin E against mercuric chloride toxicity for the testis, epididymis, and vas deferens of adult male mice, animals were treated with either mercuric chloride 1.25 mg/kg/day, vitamin E 2 mg/kg/kg, or a combination of the two treatments. Control animals were treated with water. Treatments were administered by daily gavage for 45 days. An additional group of animals treated with mercuric chloride were permitted to recover for 45 days after mercuric chloride treatments. Parameters studied included serum testosterone, epididymal sperm count, motility, and morphology, epididymal and vas deferens adenosine triphosphatase (ATPase), phosphorylase, sialic acid, glycogen and protein, testicular succinate dehydrogenase (SDH), phosphatases, cholesterol, ascorbic acid, and glutathione. Fertility was evaluated by sperm positive vaginal smears after overnight cohabitation with a female. Mercuric chloride produced a reduction in epididymal sperm count, sperm motility, and sperm viability, and there were no sperm-positive smears in this group. Biochemical tests from the male reproductive organs were also altered by mercuric chloride treatment. Coadministration of vitamin E with mercuric chloride prevented the changes in sperm and biochemical parameters and was associated with control rates of sperm positive smears after cohabitation. Animals given vitamin E with mercuric chloride also had lower concentrations of mercury in the testis, epididimyis, and vas deferens. Permitting animals to recover for 45 days after mercuric chloride treatment resulted in partial recovery of sperm and biochemical parameters. Vitamin E cotreatment has a protective role against mercury-induced male reproductive toxicity.

In the present study an attempt has been made to evaluate the effect of Tiron along with Zinc, Selenium and Vitamin E against vanadium intoxication in female albino rats. Toxicant caused significant increase in the activities of serum transaminases, serum alkaline phosphatase and lactate dehydrogenase. Significant decrease was observed in blood sugar, serum albumin and triglyceride levels whereas serum proteins, cholesterol and urea levels increased significantly during toxicity (p </= 0.001). Hepatic lipid peroxidation increased significantly, whereas significant depletion was observed in reduced glutathione after vanadium administration. The activity of glucose-6-phosphatase in the liver was also inhibited significantly after vanadium administration. A significant rise was observed in glycogen content of liver and kidney after toxicant exposure. Activities of alkaline phosphatase, adenosine triphosphatase and succinic dehydrogenase were inhibited significantly on the contrary activity of acid phosphatase elevated in kidney. Histopathological examination of the liver and kidney using light and ultramicroscopic study also substantiated the above findings. It was found that therapy with Tiron was effective but significant recovery in all the parameters was found with Tiron + Se followed by Tiron+ VitE and Tiron +Zn.
