Action of norepinephrine on the serum gastrin level.
The authors have studied the influence of endogenous norepinephrine released during exercise on the level of serum gastrin. After a period of absolute rest, 10 volunteers in good health underwent a prolonged graded exercise corresponding to 60, then 80% of the maximum theoretical heart-beat frequency. Only norepinephrine was significantly high during the course of the second phase of muscular activity. No significant change in serum gastrin was observed during the entire test.
