[The effect of autotransfusion of photo-modified blood on the growth of Walker's carcinosarcoma].

The study deals with the influence of autotransfusion of blood treated with ultraviolet light on the growth of experimental Walker's carcinosarcoma in rats. Animals of the study group survived longer than controls. Autotransfusion of the photo-modified blood did not influence tumor growth rate. The anti-anemic action, the inhibitory effect on lipid peroxidation and retardation of immunodepression by photo-modified blood are the possible mechanisms accounting for an increase in resistance to tumor growth in rats.
