Gastric antiulcer and antisecretory effects of carbenoxolone, aldosterone and desoxycorticosterone in rats. | The beneficial antiulcer actions of carbenoxolone may possibly be due to an aldosterone-like component on the gastric mucosa. This suggests that aldosterone and possibly other corticoids may have antiulcer actions. The potential gastric antisecretory and antiulcer actions of aldosterone (ALDO) and desoxycorticosterone ... | 543,742 | [

Studies on the modes of action of dicyclohexylamine and related amines with a potentiating effect on noradrenaline responses in the rat vas deferens. | Previous studies have shown that dicyclohexylamine (DCHA) and related amines with saturated and unsaturated cyclic side-chains produce a potentiation of noradrenaline responses in rat vas deferens. The present study shows that the potentiation is mediated via a cocaine-like effect, by acting as neuronal uptake inhibito... | 543,749 | [

Effect of zinc ions on the oxygen affinity of hemoglobin and the level of 2,3-DPG in normal human red blood cells in vitro. | This paper presents the results of experiments on the in vitro effect of zinc ions on the affinity of hemoglobin for oxygen and on the 2,3-DPG content of the red blood cells of healthy humans. Blood was incubated in 1.5 X 10(-3) M ZnSO4 solution for 4 h and then the oxygen affinity of hemoglobin and the hematocrit numb... | 545,945 | [

The binding constants are calculated from the binding isotherm of AMD and those of the AMD analo... | 547,179 | [
