骨髓体外組織培養法によるアドレナリン，コーチゾン，ACTHの白血球系特に好酸球に及ぼす影響に関する研究 ―特に好酸球減少の機転を中心として― 第二編 アドレナリン，コーチゾン，ACTHによる好酸球減少の機転と下垂体との関係（主として骨髄体外組織培養法による）

I have studied adrenalin, cortisone and ACTH eosinopenia in hypophysectomized dogs by means of chamber counting. In addition, the bone marrow of hypophysectomized dogs was cultivated in using the plasma of normal and hypophysectomized dogs separately, cortisone was added to each preparate. The results obtained are as follows: (1) Adrenalin eosinopeia is due to its direct influence upon the eosinophil partly through the pituitary body. (2) ACTH acts as glucocorticoid in ACTH cosinopenia. This brings about the similar result to cortisone eosinopenia. But ACTH eosinopenia has no correlation with the function of the pituitary anterior lobe, while cortisone eosinopenia requires the normal function of the anterior lobe. (3) Cortisone (compound E) alone can not cause cortisone eosinopenia but it gives hypofunctional influence and developmental disturbance upon the eosinophil in synergism of other compounds. (4) The normal functions of both the adrenal cortex and pituitary anterior lobe is necessary for eosinopenia by cortisone administration. (5) Cortisone test can be used as a test of pituitary anterior lobe function only in the case with normal adrenocortical function.
