Antidiuretic responses to osmotic cutaneous stimulation in the toad, Bufo arenarum - A possible adaptive control mechanism for urine production

Osmotic stimulation of the skin of the toad Bufo arenarum with isotonic (115 m M) or hypertonic (400 m M) NaCl solutions produced a marked and reversible antidiuresis within 5 min. No changes in plasma osmolarity were detected in the course of this response. Hypophysectomized animals exhibited a low...
