Abstract
Conclusions
1. Angiotonin (Page) has a true pituitrin-like action. 2. It contracts smooth muscle directly and not through the medium of adrenergic neural vasoconstrictor components. 3. Its action is not reversed by ethyl yohimbine as is that of epinephrine. 4. It exhibits no vasodilating action such as is characteristic of small doses of epinephrine. 5. It does not nullify the adrenolytic or sympatholytic action of ethyl yohimbine. 6. It has no effect upon cholinergically or adrenergically controlled salivation or pupillary responses.
