On March 19, 1954, patkents” a (T-1) and (T-2) were seer in Tokyo University Hospital and blood counts were performed by Dr. Sears, and Miss Tsuchitori,Yenief henetology technician. Blood smears were made amd will be examined after staining at ABCC in Hiroshima. 16 March 1954 from these two patients 4 Telsae Uww ergity by Dr. Miyoshi end one unstained slide of marrow from each patient was given to ABCC. in Hiroshima. Bone marrow specimens were obtained These will be examined after staining Dr. Miyoshi also had stained slides of marrow from patients . and . These were examined 19 March 1954 by Dr. Sears but conditions were such that only low pover lens of miscroscope could be used. No abnormality of either marrow was observed uncer these circumstances. Reports of blood counts on. and performed by Yaizu and Tokyo University Hospitals are t2bul'ted helow as well as the counts performed by A8CC members. 20 March 1954 - The 21 patients at Yaicu were visited but ARCC staff were not permitted to obtain any blood or bone marrow specimens. Reports of blood counts performed by Yaizu staff are tabulated below. Blood slides had been made 17 March 1954 on all patients and sent to Tokyo University Hospital. On 22 March 1954 these slides were examined by Dr. Sears and Miss Tsuchitori. Differential count of 100 cells was performed on each specimen as vell as 2 thorough low pover lens study. In gener21, these blood smears, while adequate, were not of the ouczlity considered desirable by aBCC. The smears were made on glass slides rather than cover slips and the latter method is considered to give greater accuracy. Inere was distortion of many \hite blood cells so tht identification was rendered @ifficult. The stain was lighter than that used by ABCC and recognition of platelets was especially unsatisfactory. However, a gener 1 i..pression of White blood cell distribution, am Red blood cell am platelet ippecrence could be obtzcined and these are tabul.ted below. There was satisfactory reenent between reported shite blood counts and appearance of white cells on Ades; i.e., there was an abundance of cells on stzined slides whose reported counts were normal or slightly elevated and an apparent paucity of cells on the slide from (T-16) whose reported “hite cell count was 2900 on 17 March 1954. The blood slide from (T-19) hed apparently become damaged and only a snall portion of the material remained. could not be observed satisfactorily.
