was noted several days before entry into port. After entry into port the patients wore treated at Yakizu, where Dr. Miyoshi and others of the treatment group of Tokyo University had been sent. On 28 March, 16 of the crow members were hospitalised at the First Tokyo National Hospital and five of them at tho hospital attached to Tokyo University. The number of patients at the University Hospital then was seven, as two had bean hospitalized already. I was mainly in charge of the 16 patients at the First Tokyo National Hospital, progress until the time of hospitalization. This 1s the summary of Sunzary of the Conditions of the Discase and tho Treatment Furukawa: Now let us discuss olinical matters, As other medical Kuuatori: Let me speak about the minner in which the crew was ate journals have already reported the external wounds, I shall ask Dr. Kunatori to discuss chiefly the changes in internal orgens, especially hematopoietic orgens, and particularly the matter of liver dysfunction. tired at the tine of exposure. Most were wearing round-neck shirts, under spring haord or sirilar garments, and caps; some wore head-bends. At the time of hospitalisation, the bummed areas were the head, neck, and wrist. As the nen were wearing belts, blisters formed at the navel above the belts from ash which settled in the waist region. The skin showed red pisnentary depcsits and desquamticne The depilation occurred chiefly in the occipital region. As inpetigo followed where hair hed fallen out, I treated it with umguent. Progress was comparatively favorable, but a fow of the men still have impetigo in the oc~ cipitel rosion. Generally specking, ncw hair began to grow in from. about Juno and the potients at the Firat Tokyo Hospital regained their norzal hair distribution about July. Tha abdoninal wounds left cica~ trices and the pignentation is gone; but pigments generally are thought to daposit very gradually, Leaving the question of external wourds, let us discuss changes in the blood, which we considered an important problem. The men were hos~ pitalized on 28 March, 4 weeks after the explosion, In the case of Hiroshima, this was the period after which c s in the blood grew more marked. The newspapersreported that the patients at the First Tokyo National Hospital ware mild cases; but in realitv sozs of thea wore serious, as I shell deseribe later, and Hr. . was one of the most sorious, Cons <f the core sericus cases had anenia of about 3 million. The whites cell cout decreased gradually from the beginning of April; one patient at the First Tokyo National Hospital had a comt a3 low as 1,500 and one at the Tokyo University Attached Hospital, as low as £00, The thrombecyte- cout also decreased. By removing bone marrow, wa found that the mmber of cells had decroased; this conditicn is called mpnarslophthisis, Examination of the cells showed sone dogree of nucleus disintegration in all cases, including those where tha nucber of cells did not decrease, and soms showed s tendency to slight henxorrlmge. We gave blood transfilsions in these eases, Thonses to transfusion, the red cell oonnt ‘ncreased to about 5 million but te siitched to dry blood plasma to avoid excessive insreise in rod calls. The patients who were not aneaie fron ths beginning did not receive blood transfusions but only dry blood plasma. In geners*, we stopped the transfusions after the 2—non'.h period of April and Fay.
