Abstract
From experiments on 5 dogs it is concluded: (1) Mg salts given orally cause an inhibition of hunger contractions that can be counteracted by giving Ca salts. Ca administration per se has no effect on hunger contractions. (2) Central effects caused by injections of Mg and Ca salts may mask any true effect of these salts on hunger contractions. Cessation of hunger contractions and loss of tone were the effects observed. Very small doses of Ca have no effect on hunger contractions. A Ca injection following Mg injection does not diminish the depressive action of the Mg on the hunger contractions. (4) Mg depresses rhythmical contraction of gastric muscle strips. Ca enhances gastric strip contraction. Ca after Mg depression allows contraction to return to normal more quickly than does bathing with the original Locke''s solution. In bathing with Ca and Mg solutions simultaneously, the Ca effects predominate.This publication has 0 references indexed in Scilit:
