Leukocyte changes following intramuscular injection of epinephrine and epinephrine congeners, with observations on the alterations induced by adrenergic blocking agents

Primary and Secondary Leucocyte Changes Following the Intramuscular Injection of Epinephrine Hydrochloride 1

“…The purpose of this paper is to describe the alterations in the number of circulating leucocytes during both phases of the response to epinephrine in normal human subjects, and to show the relation of the primary phase (the immediate alterations) to the secondary phase (the delayed changes). A preliminary report of this work has appeared (16).…”
