Abstract
Summary
Acute administration of d,l-isoproterenol (50 μg/kg body wt, sc) to turkeys was accompanied by a significant increase in water intake which occurred within 1 h after treatment. This dose of d,l-isoproterenol also induced a copious, watery urine excretion. Acute administration of d,l-isoproterenol (200 μg/kg body wt, sc) increased the temperature of the skin of the left thigh within 10 min after treatment. Skin temperature reached maximal levels within 40 to 60 min after treatment. Heart rate of turkeys administered d,l-isoproterenol (200 μg/kg body wt, sc) increased approximately 100 beats per minute within 25 min after treatment. With the exception of the diuresis, the turkey responds to administration of isoproterenol in the same fashion as the mammal.
We thank Miss Charlotte Wright for drawing the figures, and Mr. T. W. Carlisle for technical assistance.
