摘要：

1. 1. In three preferentially terrestrial species, Phylomedusa sauvagyi, Bufa paracnemis and Ceratophis ornata, clearances of urea were always found lower than those of inulin. 2. 2. These data, indicative of passive urea reabsorption, are in contrast with what should be expected if active urea secretion were a mechanism of water conservation. 3. 3. A hypothesis is advanced suggesting that passive reabsorption of urea insted of active secretion helps to keep a hypotonic urinary reserve in the bladder. © 1968.
