[Growth suppression of transplantable tumors in experimental animals given soya proteins].
ABSTRACT The development of a malignant process and antitumor treatment leads to the occurrence of a variety of complications. It is expedient to use biological regulators of natural origin to eliminate the side effect of chemical drugs and to improve the outcomes of antitumor therapy. The antitumor effect of soya proteins and their influence on antibody formation and oxidative processes in the sera of tumor-bearing animals were investigated. Soya proteins are shown to retard the development of a tumorous process, modulate the therapeutic effect of 5-fluorouracil, enhance antibody formation, and normalize serum oxidative processes.
