Faster healing of local radiation lesions to the skin in experiments involving multiple preliminary exposure to ulraviolet radiation. [Rats, x radiation]

Localized lesions of the skin were produced in rats by exposure to x radiation. Rats were exposed to uv radiation at different intervals before and after exposure to x radiation. Faster healing of radiation lesions was observed in all experiments following the use of uv radiation. A decrease in the number of exposures of uv and particularly a reduction of the interval between the start of uv and x radiation diminished the prophylactic efficiency of uv radiation. (HLW)
