Abstract

The ornithine decarboxylase (ODC) activity and concentration of polyamines have been studied in small and large intestine during 1,2-dimethylhydrazine-induced carcinogenesis in rats. Changes in the polyamine biosynthesis consisting both in enhanced ODC activity and an increase of the intracellular content of putrescine, spermidine and spermine. Process of the polyamine synthesis activation proceeds in two phases: the most expressed and similar changes in polyamine metabolism factors have been observed at early (the 1st month) and late (the 5th-6th months) stages of carcinogenesis. It is supposed that intensification of the polyamine synthesis is a typical feature of malignization in the gastrointestinal tract.
