THE ACTION OF X-RAY IRRADIATION AND PAINTING WITH CARCENOGENIC HYDROCARBONS ON THE PHOSPHORUS CONTENT OF THE EPIDERMIS

[摘要] In rats, X-ray irradiation with 3000 r and in mice one painting with methylcholanthrene and benzpyrene resulted in a pronounced decrease of the total P content of the epidermis. Following X-ray treatment, the extent of the decrease was greater and of longer duration, whereas in the case of chemical carcinogens, the P content returned almost to normal on the 4th day after the treatment. Repeated painting with methylcholanthrene again effected a diminution of the P content of the epidermis which was even more pronounced that that following the first application.
