[Effect of monochromatic red lighting potentiating antitumor action of cyclophosphamide injected with autoblood]

Blood was sampled from the caudal vein of rats, incubated with cyclophosphamide with autoblood, exposed to red light (0.31 Jcm2) and re-injected into the femoral vein. Lighting in conjunction with the antitumor action of the drug was followed by significant inhibition of large-size tumors, longer survival and development of integral criteria which describe cumulative antitumor effect.
