Abstract:
:5 adrenalectomized subjects and 8 healthy volunteers underwent an insulin test during which acid secretion and plasma adrenaline, noradrenaline, dopamine and gastrin concentrations were measured. Plasma glucose concentration fell by greater than 50% in all subjects. The mean plasma adrenaline concentration increased markedly (greater than 1,000%) in the normal group but was unchanged in the adrenalectomized group. In all subjects, plasma noradrenaline concentration increased moderately, whereas plasma dopamine levels remained unchanged. Clear-cut increments in plasma gastrin concentration were seen only on 3 participants, each of whom responded to insulin hypoglycaemia with an extremely high adrenaline release. Basal and peak acid output were similar in adrenalectomized and normal subjects. The results suggest that circulating catecholamines contribute to the control of gastrin and acid secretion in man only during circumstances with high plasma catecholamine levels, e.g. severe stress.
