Abstract:
:The serum concentration of alpha1-fetoprotein (alpha1F) was determined in rats following exposure to the hepatocarcinogen, 3'-methyl-4-dimethylaminoazobenzene, and its analogs. Small quantities of the carcinogen caused a rapid and significant elevation of alpha1F. Neither 2-methyl-4-dimethylaminoazobenzene nor p-aminoazobenzene resulted in any elevation of alpha1F. Further, under circumstances wherein 2-methyl-4-dimeth-laminoazobenzene is reported to become carcinogenic, i.e., when administered at the time of 70 percent hepatectomy, neither elevation of alpha1F nor histological alteration of the liver was noted. The increase in alpha1F after 3'-methyl-4-dimethylaminoazobenzene exposure is the result of a highly selective interaction. The possible contribution of hepatocyte mitosis to the elecation of alpha1F seen during chemical carcinogenesis is emphasized.
