The protective effect of different drugs in rats poisoned by sulfur and nitrogen mustards.
Based on the recent pathognomic accomplishment in the mechanisms of toxic actions, the favorable degree of protection was achieved by several drugs in acute poisoning of rats with sulfur and nitrogen mustards. It has been established that dexamethasone, promethazine, vitamin E, heparin, and sodium thiosulfate (a) prolonged the survival time in animals poisoned by 3 LD50s of toxic agents, (b) diminished the lethalty (with the protective indices ranging from 1.5 to 2.7), (c) antagonized the decrease of body weight, and (d) lessened the degree of pathological organ changes. The simultaneous administration of two or three of the drugs mentioned, of which sodium thiosulfate as chemical inactivator of the toxic agents was basic and consonant component, led to the further increase in effectiveness. It is concluded that satisfactory results obtained in this study speak in favor of the basic pathological effects of mustard gases, as well as possible causes and their possible ways of action as postulated by Dannenberg (1983).
