Polyamine levels in sarcoma-bearing rats in relation to growth and necrosis of the tumour cells.
Putrescine (PU), spermidine (SPD) and spermine (SPM) levels in blood serum of MC Sa 1828 P-bearing rats have been studied in relation to tumour weight and the histological picture. A statistically significant increase of PU and SPD was found in the course of tumour development. Decrease in the level of polyamines in the necrosis stage was also found. Only increased SPD level appeared in the period of intensified necrosis, accompanied by lymphocyte infiltration.
