摘要: Abstract 2,2′-Dichlorodiethyl sulfide (sulfur mustard, HD) extensively alkylates DNA in a concentrationdependent manner many cell types. We have proposed biochemical hypothesis that explains HDinduced injury by linking alkylation and breaks with activation of poly(ADP-ribose) polymerase, resulting depletion cellular NAD + . This was tested treating human leukocytes HD to determine whether occurred as predicted. These cells demonstrated decrease levels which dependent on both concentration time after exposure. Inhibitors polymerase or substrates for synthesis were able prevent the HD-induced decrease.
