Frogs reabsorb glucose from urinary bladder

Article Abstract:

The urinary bladder of amphibians stores fluid for use when water is in short supply. New research shows that the urinary bladder of the wood frog, Rana sylvatica, also stores glucose for reabsorption by its body as it recovers from extremely low temperatures, when some 70% of its body water freezes during hibernation. By infusing the bladders of live frogs with glucose containing a radioactive marker it was found that glucose permeated the bladder lining to enter the general circulation.
