The use of isocyanates in industry has been increasing and, therefore, the potential for human exposure has also increased. Two such isocyanates are diphenylmethane-4,4'-diisocyanate (MDI) and dicyclohexylmethane-4,4'-diisocyanate (SMDI). Furthermore, there are only a few reports describing the toxicity of these
