“…It has been suggested that TFGb1 plays a role in the pathogenesis of chronic SM toxicity (Ghanei and Harandi, 2007;Poursaleh et al, 2012). Generation of reactive oxygen species have been previously shown to influence expression of TFGb1 (Jain et al, 2013).…”

Sulfur mustard (bis 2-chloroethyl ethyl sulfide, SM) is a powerful bi-functional vesicating chemical warfare agent. SM tissue injury is partially mediated by the overproduction of reactive oxygen species resulting in oxidative stress. We hypothesized that using a catalytic antioxidant (AEOL 10150) to alleviate oxidative stress and secondary inflammation following exposure to SM would attenuate the toxic effects of SM inhalation. Adult male rats were intubated and exposed to SM (1.4 mg/kg), a dose that produces an LD 50 at approximately 24 h. Rats were randomized and treated via subcutaneous injection with either sterile PBS or AEOL 10150 (5 mg/kg, sc, every 4 h) beginning 1 h post-SM exposure. Rats were euthanized between 6 and 48 h after exposure to SM and survival and markers of injury were determined. Catalytic antioxidant treatment improved survival after SM inhalation in a dose-dependent manner, up to 52% over SM PBS at 48 h post-exposure. This improvement was sustained for at least 72 h after SM exposure when treatments were stopped after 48 h. Non-invasive monitoring throughout the duration of the studies also revealed blood oxygen saturations were improved by 10% and clinical scores were reduced by 57% after SM exposure in the catalytic antioxidant treatment group. Tissue analysis showed catalytic antioxidant therapy was able to decrease airway cast formation by 69% at 48 h post-exposure. To investigate antioxidant induced changes at the peak of injury, several biomarkers of oxidative stress and inflammation were evaluated at 24 h post-exposure. AEOL 10150 attenuated SM-mediated lung lipid oxidation, nitrosative stress and many proinflammatory cytokines. The findings indicate that catalytic antioxidants may be useful medical countermeasure against inhaled SM exposure.Key words: sulfur mustard; chemical weapons; antioxidant.Sulfur mustard (SM) is a chemical warfare agent possessing strong alkylating properties that induces inflammation and tissue necrosis. SM exposure produces delayed and highly incapacitating injuries that can be lethal (Anderson, 2015). SM was used during World War I and is still maintained in the chemical weapons arsenals of several countries (Kehe and Szinicz, 2005). A specific and effective antidote is not available for use after SM exposure despite research conducted for nearly 100 years (Kehe and Szinicz, 2005). The population most at risk for exposure to SM is comprised of soldiers and individuals working or living near storage depots, but SM is also considered to be a potential terrorist threat due to its low cost of production and simple synthesis.Sulfur mustard (SM) vapor adversely affects the skin, eyes, and the respiratory tract. The respiratory tract is highly

“…Other laboratory data to help in developing a prognosis are needed, including DLCO and body plethysmography findings. These issues are discussed by Ghanei et al (2008) and Ghanei & Harandi (2007). (3) It is necessary to interpret the differences in various studies on the level of cytokines.…”
