Reduction of papilloma size by ultraviolet irradiation in the Japanese newt, Cynops pyrrhogaster.


Experiments were conducted on 44 captive Japanese newts (Cynops pyrrhogaster) to test the hypothesis that ultraviolet (UV) irradiation might inhibit growth or induce regression of spontaneous skin papillomas of probable viral origin. An empirically derived exposure to UV irradiation (42 microW per cm2 per day) induced reduction of papilloma size which began… (More)
