[Effect of blood serum proteins and glucose on the polyamine content of the liver of rats with Guérin's carcinoma].

The paper deals with an evaluation of the levels of polyamines (putrescin, spermidine and spermine) in the liver tissue of rats bearing Guerin's carcinoma, after injection of blood serum proteins and glucose. Tumor growth was followed by an increase in polyamine levels in the liver tissue of tumor-bearing rats. Injection of blood serum or glucose prevented the development of the said changes. It was inferred that tumor-induced changes in polyamine profile of the host liver are nonspecific. They are compensatory and intended for correction of homeostasis of the host.
