V. Effect of Epinephrine, AGTH and Cortisone on Citrate, Calcium, Glucose and Phosphate Levels in Rabbits.

Summary1. Epinephrine subcutaneously causes a rise in calcium, citrate and glucose levels and a fall in phosphate and potassium levels. 2. Cortisone intramuscularly causes a rise in glucose and phosphate levels and a fall in calcium and citrate levels. 3. ACTH intramuscularly causes a rise in citrate and a fall in calcium levels. 4. It is suggested that the balance between ACTH, epinephrine, insulin and cortisone secretion, because of their effect on citrate, calcium and phosphate levels, play a significant role in the maintenance of the calcium ion concentration of the plasma.
