[Suppression of the anaphylactic response of isolated smooth muscle organs by potassium arsenite].

A possibility of inhibition of the anaphylactic reaction of the isolated human smooth muscle and smooth muscle of guinea pigs by inorganic arsenic was studied. Liquor kalii arsenicosi (Fowler's solution) completely blocked the development of anaphylactic bronchospasm and anaphylactic release of the pharmacologically active substances from the guinea pig lungs.
