[Early histochemical markers of hepatocarcinogenesis]

Results of hepatocarcinogenesis studies are reviewed. The studies were made using different histochemical markers which permit revealing hyperplastic nodules in the liver. Determination of the gamma-glutamyl transpeptidase, ATPase, glucose-6-phosphatase activities and the glycogen, iron, alpha-fetoprotein contents are advisable when studying early changes in different cell populations during hepatocarcinogenesis.
