title: Acute urinary bladder toxicity of a polyurethane foam catalyst mixture: a possible new target organ for propionitrile derivative.
abstract: The toxicity of the mixture NIAX-ESN which contains 95% dimethylaminopropionitrile was evaluated in male rats. Large doses (2.0 ml/kg ip) rapidly produced CNS excitation followed by depression and death. The mixture (given orally as two doses of 0.31 or 0.62 ml/kg respectively) induced acute urinary bladder lesions in 3 days. The changes consisted of massive transmural edema, acute ulcers and inflammation and, occassionally hemorrhagic necrosis of the bladder wall.
