-15 remain dangerously low: yesterday's 800, one at 2100; one at 1700; and one at 1500 today from Tsuzuki reported last of these showed increased coagulation time, and complained of not feeling well. These three patients plus two original patients at Tokyo receive 100-300 ce transfusions daily; lowest blood count patient additionally given 600,000 units penicillin daily. At this point full and free access to patients for ABCC staff seems to us, on basis Eisentud and Morton advice, irreducible U. S. interest. Data possibly derivable from these patients and available nowhere else may have highest importance U. S. scientific security and planning. Request Department and AEC evaluation this point. I would be prepared to go to Yoshida and put case for immediate cooperation on following lines. (A) Contimed decline of white blood counts as reported informally by Japanese physicians to Dr. Morton, indicates need for prompt application of best available techniques and therapeutic procedures. (BE) Future wellebeing of FM sailors is being handicapped because Japanese physicians have not chosen to consult with Dr. Morton's staff; (C) Extent to which government will accept liability for this unfortunate accident will depend on extent to which, in our judgment, test available medical techniques have been applied; (D) Japanese government has moral responsibility to assure patients every opportunity to regain health; (E) A friendly attitude towards the U. S. requires our government be given every opportunity to minimize its potential liability by utilization of American-trained medical scientists on staff of ABCC: (F) Potential findings of importance to national interests both countries. - is eet LA CEIVES.
