In the present study, the effects of sodium 2 3 dimercaptopropane sulphonic acid (DMPS) on some biochemical and histological parameters in mice, exposed to 1/4LC 50 concentration of SM vapor (10.5 mg/m\+3) were examined over a period of seven days. Exposure of SM resulted in a significant loss of blood, hepatic and pulmonary glutathione (GSH) and an elevation of hepatic and pulmonary oxidized glutathione (GSSG). These biochemical changes were accompanied by a number of histopathological alterations. The most prominent was congestion and degeneration in viscera and obliteration of chromatin material. These biochemical and histopathological changes were less marked in animals pre administered with DMPS followed by DMPS exposure indicating some protective value of the thiol (DMPS) against SM induced oxidative injury in mice.展开更多
