Abstract
Sulphur mustard (SM) gas is a poisonous chemical agent causing various systemic action in laboratory animals. There is no definite treatment for disorders induced by SM. In this study, the effect of vitamin E alone and in combination with dexamethasone on the pathological changes in the kidney and liver of SM-exposed (SME) guinea pigs was examined. Guinea pigs were divided into five groups (n = 5 in each). These groups were exposed to ethanol (control group), 100 mg/m(3) inhaled SM (SME group), SME treated with vitamin E, 600 mg/kg (SME + E), SME treated with dexamethasone, 5 mg/kg (SME + D), and SME treated with both drugs (SME + E + D), respectively. Pathological evaluation of the kidneys and livers was done 14 days post exposure. There were statistically significant pathological changes in the liver and kidney of SME group compared to control animals (p < 0.05 to p < 0.001). Treatment of SME animals with vitamin E, dexamethasone and their combination caused statistically significant improvement in the pathological changes in the livers and kidneys (p < 0.05 to p < 0.001). These results showed a preventive effect of vitamin E on pathological changes in the liver and more prominently in the kidneys of SME guinea pigs.
