Clinico-pathological changes induced in rats treated with amine-curing agent for epoxy resin, bis(4-amino-3-methylcyclohexyl)methane.

S Ohshima et al.

The Journal of toxicological sciences, 11(2), 79-93 (1986-05-01)

Amine-curing agent for epoxy resin, bis(4-amino-3-methyl-cyclohexyl)methane (commercial name; Laromin C) has been suspected to have induced in the workers some toxic signs such as collagen disease like scleroderma or polymyositis. Subacute toxicity of this agent was studied in rats following

Dermatosen in Beruf und Umwelt. Occupation and environment, 34(3), 61-67 (1986-05-01)

For the stimulation of research on scleroderma and the prophylaxis of occupational scleroderma-like diseases and the prevention of iatrogenic injuries, respect., it is important to know the inducing environmental substances.
