BLACK LIGHT INDUCTION OF SKIN TUMORS IN MICE

[摘要] Albino inbred mice (A/J strain) exposed to 40 W black light fluorescent lamps (BLB) for 12 h a day for up to a year developed inflammatory and hyperplastic responses on hairless ear and tail skin, but not on back skin covered by hair. After 1 yr of such exposure, many individuals developed papillomas, carcinomas and sarcomas on their ears and tails. It may be concluded that black light is a skin carcinogen for A/J mice.
