Reynolds ES, Moslen MT, Szabo S, Jaeger RJ, Murphy SD: Hepatotoxicity of vinyl chloride and 1,1-dichloroethylene. Am J Pathol. 1975 Oct;81(1):219-36.
Role of mixed function oxidase system.. Vinyl chloride, an occupational carcinogen, produces acute liver injury in rats pretreated with phenobarbital or Aroclor 1254. Injury appears related to morphologic changes in the endoplasmic reticulum. The degree of injury, as indicated by elevation of serum enzymes derived from the liver, correlates with the magnitude of induction of cytochrome P-450 and its reduction by NADPH. Hepatic injury following 1,1-dichloroethylene exposure differs strikingly from that caused by vinyl chloride and appears to involve plasma membranes, mitochondria, and chromatin and spares endoplasmic reticulum. Induction of cytochrome P-450 appears to protect against 1,1-dichloroethylene but not vinyl chloride. |
