Abstract of: Holliday, C.W. (1978). Glucose absorption by the bladder of the crab, Cancer magister(Dana). Comp. Biochem. Physiol. 61A: 73-79.

1. Glucose injections in C. magistercause glucosuria, with an apparent hemolymph threshold of approximately 100 mg%.

2. Glucose is absorbed from crab Ringer solution introduced into the bladder. Phlorizin blocks glucose absorption by the bladder and causes glucosuria when injected.

3. Glucose is absorbed from crab Ringer solutions in vitroby both sides of the bladder, but the flux of free glucose across the bladder in either direction is negligible.

4. Eyestalk ablation had no effect on serum or urine glucose levels or on glucose absorption from Ringer solution introduced into the bladder.
