Statements Concerning Ishiyama

Statement of Tsuchiya (420, 9 June 1947) Heard rumor that Ishiyama made an announcement stating that he had used American PWs for experi­mental use— this was supposed to have been made in May 1945 at Surgical Congress, but Tsuchiya there, did not hear it, although Ishiyama did speak of reviving patients from bombing shock.

Tsuchiya then changes story, says it was another doctor and not Ishiyama who spoke on bombing shock at Moji and Shimonoseki. Ishiyama showed a picture and demonstrated how he treated patients for some illness, but doesn't recall what it was.

Also heard that men with lower scientific level wanted Ishiyama and other professors to resign because of his experiments.

Tsuchiya heard that Ishiyama said at Surgical Congress, after disser­tation on AA, that they could not keep pace with AA, so that the best thing to do would be to use sea water as a blood substitute. Ishiyama did say that raw seal water would be very dangerous, but alright if filtered to remove bacteria and then used as a blood substitute.

Statement of Tanamachi (420, 9 June 1947) After Komori had gone to Tanamachi's hospital for treatment (June or July 1945) Ishiyama came and took Komori with him the next day after he spent the night at this hospital.

After Komori's death— about a month afterwards, but before the end of the ear, Ishiyama came to see Tanamachi, said that Komori had one of his assistants inject some anti-toxin in his neck artery, which was not normal medical practice, then died of tetanus, further said it was foolish to use anti-toxin the way that he had used it.

Tanamachi heard rumors that Ishiyama had treated captured Americans very badly who had been brought to the University Hospital.

Statement of Arakawa (420, 9 June 1947) Heard from son-in-law, Junichi Wakisaka that Ishiyama was to leave KIU because "he had done something that could not be made openly." Later Arakawa read in Nishi Nippon Shlnbum of IS July about an instructor mistreating Prisoners.

Arakawa knew that Ishiyama had been experimenting in brain surgery. After first interrogation by Barnard, Arakawa went to Minister of Education's office, found that Ishiyama had made research in brain surgery, nervous system and liver surgery in 1942 and 1943.
