ResumoMesotocin and arginine vasotocin were injected intravenously once at various dosage levels (.0025 to 25 μg/kg body weight) immediately after an intravenous injection of 15 mL/kg body weight saline solution into hens in which an artificial anus had been surgically created, and the volume of urine excreted during a 5-h period, following the injection, was measured. Arginine vasotocin caused a monophasic, dose-dependent decrease in urine volume. By contrast, mesotocin was biphasic: at .025 and .25 μg/kg body weight it decreased urine volume with the same efficacy as arginine vasotocin, whereas it dramatically increased urine volume at the higher doses (2.5 and 25 μg/kg body weight).
