Experiments on photoreactivation of bacteriophages inactivated with ultraviolet radiation.
Kelner (1949), working with conidia of Streptomyces griseus, discovered that light belonging to the visible range is capable of reactivating biological material that has been rendered inactive by ultraviolet radiation (WJY). Shortly after Kelner's discovery was known, a similar phenomenon in bacteriophages (bacterial viruses) was observed by accident. Plates of nutrient agar containing UV-inact...
متن کاملPhotoreactivation in Vitro of Ultraviolet Inactivated Hemophilus Influenzae Transforming Factor
Hemophilus influenzae-transforming DNA, which has been inactivated by ultra-violet radiation, is reactivated by visible light in the presence of a cell-free extract of Escherichia coli B. The time rate of reactivation is increased by increasing the E. coli extract concentration, the temperature, and the intensity of illumination. Only DNA containing an ultraviolet-damaged genetic marker exhibit...

متن کاملPhotoreactivation of Ultraviolet Radiation-induced Skin and Eye Tumors of Monodelphis domestica1
Chronic exposure of the opossum Monodelphis domestica to UV radiation (UVR) leads to the formation of cutaneous and corneal tumors. Groups of shaved opossums were exposed 3 times/week to: (a) UVR alone; (h) UVR followed immediately by l h of photoreactivating light (PRL) (320-700 nm); (c) l h of PRL followed by UVR; and (rf) l h of PRL alone. Exposures were terminated after 70 weeks of treatmen...
متن کاملPhotoreactivation of ultraviolet radiation-induced skin and eye tumors of Monodelphis domestica.
Chronic exposure of the opossum Monodelphis domestica to UV radiation (UVR) leads to the formation of cutaneous and corneal tumors. Groups of shaved opossums were exposed 3 times/week to: (a) UVR alone; (b) UVR followed immediately by 1 h of photoreactivating light (PRL) (320-700 nm); (c) 1 h of PRL followed by UVR; and (d) 1 h of PRL alone. Exposures were terminated after 70 weeks of treatment...
