[Action of compounds which predominantly affect the peripheral M-cholinoreactive systems on the bone marrow eosinophils].

Experiments on rats have shown that the blockade of M-cholinoreceptors with atropine (50,100 and 150 mg/kg) delays, while the stimulation of the M-cholinoreceptors with aceclidine (5, 10 and 15 mg/kg) intensifies the release of mature eosinophils from the bone marrow to the circulating blood. It is concluded that the peripheral M-cholinoreactive systems participate in the control of the release of the mature bone marrow eosinophils into the blood.
