A Mouse Model of Acute and Delayed Complications of Sulfur Mustard Analogue, 2-Chloroethyl Ethyl Sulfide
Background: Numerous studies have been conducted on humans, animals, and cell cultures exposed to Sulfur Mustard (SM). However, the precise mechanism and cause or long-term pattern of SM injuries are not well defined. There is no protocol available for treating people with severe eye, lung, and skin ailments. The current study aimed to develop an animal model of the acute and delayed complicati...
متن کاملAirway tissue factor-dependent coagulation activity in response to sulfur mustard analog 2-chloroethyl ethyl sulfide.
Acute lung injury is a principal cause of morbidity and mortality in response to mustard gas (SM) inhalation. Obstructive, fibrin-containing airway casts have recently been reported in a rat inhalation model employing the SM analog 2-chloroethyl ethyl sulfide (CEES). The present study was designed to identify the mechanism(s) causing activation of the coagulation cascade after CEES-induced airw...
متن کاملA role for mitochondrial oxidative stress in sulfur mustard analog 2-chloroethyl ethyl sulfide-induced lung cell injury and antioxidant protection.
Sulfur mustards (SMs) have been used as warfare agents since World War I and still pose a significant threat against civilian and military personnel. SM exposure can cause significant blistering of the skin, respiratory injury, and fibrosis. No antidote currently exists for SM exposure, but recent studies, using the SM analog 2-chloroethyl ethyl sulfide (CEES), have focused on the ability of an...
متن کاملInhibition of two-stage carcinogenesis in mouse skin with bis(2-chloroethyl)sulfide.
ICR/Ha Swiss mice, 30 females/group, were given a single application of 20 mug 7,12-dimethylbenz(a)anthracene, followed 2 weeks later by three times weekly applications of phorbol myristate acetate (PMA), 2.5 mug/application. In the accompanying inhibition experiments, sulfur mustard [SM; bis(2-chloroethyl)sulfide] was applied at a dose of 20 mug/application during the promotion phase, either o...
متن کاملSelective targeting of selenocysteine in thioredoxin reductase by the half mustard 2-chloroethyl ethyl sulfide in lung epithelial cells.
Thioredoxin reductase (TrxR) is a selenocysteine-containing flavoprotein that catalyzes the NADPH-dependent reduction of oxidized thioredoxin and plays a key role in regulating cellular redox homeostasis. In the present studies, we examined the effects of 2-chloroethyl ethyl sulfide (CEES), a model sulfur mustard vesicant, on TrxR in lung epithelial cells. We speculated that vesicant-induced al...
