This project investigated the mechanism of bis (2-chloroethyl) sulfide (sulfur mustard, HD)-induced cutaneous vesication using the isolated perfused porcine skin flap (IPPSF) and in vitro cell cultures. Treatment of IPPSFs with 5.0 mg/ml of HD results in a characteristic increase in vascular resistance, decrease in glucose utilization, and the formation of gross and microblisters. The first study demonstrated that the vascular changes associated with HD vesication are accompanied by increases ...
