[Effect of calcium ions on adrenal glucocorticoid function]

In the experimental dogs and healthy humans it was shown that calcium ions promote activation of the adrenal glucocorticoids function, which duration is dependent on the day time. In patients the influence of calcium ions on the blood 11-hydroxycorticosteroid concentration is dependent on the initial steroid level and concentration of injected calcium chloride solution. The infusion of 1% calcium chloride solution exerted a stable effect. Possible mechanisms of the changes observed are discussed.
