The presence of sclerosis-inducing glycosaminoglycan in the skin was confirmed in an experimental skin sclerosis induced by a chemical compound. An experimental skin sclerosis was first produced in the mouse with bis(4-amino-3-methylcyclohexyl)methane. Out of glycosaminoglycans isolated from the slightly changed

Repeated oral administration of an amine-curing agent for epoxy resin, bis(4-amino-3-methylcyclohexyl)methane, gave rise to severe damage in the choroid plexus of rat brain. The damaged epithelium presented varying degrees of swelling and hydropic vacuolation on light microscopy, and varying numbers
