Phosphorescence of Rat Kidneys Cooled in Liquid Nitrogen

Cut surfaces of rat kidneys exhibit intense, reproducible, and very detailed phosphorescent patterns after they are cooled with liquid nitrogen and then exposed to shortwave ultraviolet radiation. Ligation of the renal blood vessels for a period of 6 to 24 hours destroys most of this phosphorescence, whereas a ligation of the ureter has no effect on kidney phosphorescence.
