THE EFFECT OF ULTRAVIOLET LIGHT ON CHEMICAL CARCINOGENESIS

[摘要] The effect of acute ultra-violet reactions on 9, 10-dimethyl-1, 2-benzanthracene (DMBA) induced tumorigenesis was investigated. Relatively intense exposures to UV rays shortly after the application of the carcinogen did not enhance tumor production. Application of the UV energy prior to treatment with DMBA appeared to increase precancerous plaque formation and to a lesser extent tumor production.
