The bacteriological experiments of the Japanese invaders using Chinese as "experimental material" were carried out not only in their special forces, but also in the medical universities under their control. This can be amply demonstrated by a paper written by Masaji Kitano on January 11, 1939 entitled "A Study on The Prevention of Typhus Blight- Human Experiments with Homemade Typhus Vaccines".
In 1948, Tsutomu Kono, a typhoid expert who had worked at the Changchun Health Technology Factory, died of illness in Changchun. A Chinese named Zhang Dahua, who was with him, accidentally discovered the paper from his relics. The report was signed as Masaji Kitano, Shigeru Iwata, and Ei watanabe.
Masaji Kitano, who had been the commander of the 731 Unit, was a professor at puppet medical university at the time, and Shigeru Iwata and Eiwabe were also at the university, one was a lecturer in microbiology, the other was a researcher, and they were both assistants to Kitano when he was experimenting with bacteria.
The report is written in Japanese, with the word "secret" on the cover with a red pen, and the full text is about 15,000 words, detailing how to use living people to conduct bacterial efficacy experiments and experimental results, as well as 50 charts.
The paper said: "10 volunteers and 3 death row inmates were obtained in Linjiang Badaogou and were given the opportunity to do human experiments." The names of the 13 innocent victims were: Sun X Ming, Qi X Shan, Qin X Gui, Wang X Zheng, Li X Chun, Chen X Ru, Zong x Yao, Cao X Guang, Zong X Qin, Jiang X Kai, Li X Yi, Li X Chun, Han X Xue.
Although Kitano wrote these people as "death row prisoners" or "volunteers", he did not dare to write out their golden names, and deliberately cut out a word in the middle of the name. This shows that his behavior is unseemly.
In the "experimental results" of the report, it is written: "Zong X Yao (death row prisoner), male, 74 years old, came from Haiyang County, Shandong Province 30 years ago to mengjiang farming, su healthy, has not suffered from serious illness, acute fever, parents unknown. On the night of the ninth day after the injection, the head was slightly painful, tired, and on the evening of the tenth day, sudden cold fever occurred, and the body temperature rose to 38.3 ° C - 40 ° C. Continued for two days, after the fourteenth day, the body temperature was 39.3 ° C - 40 ° C. Sixteenth day autopsy.
During the course of the disease, there are symptoms such as low back pain, anorexia, thirst, tiredness, and joint pain. On the evening of the thirteenth day, the headache increased, dizziness, after which the speech was slurred, the tongue was slurred, the muscles of the face and tongue were trembling, the food was not eaten, the conjunctiva was congested, the tongue was very thick, the abdomen was sunken, and the spleen was enlarged. ”
After dissecting Zong Yao's body, Kitano wrote: "The spleen is about 3 times that of a healthy person, the membrane is tight, dark red, the face is bloody, grayish white, red, soft, the spleen and the filtration cells are not clear, it becomes infectious, and there is no significant change in other organs."
What kind of people are these "volunteers" and "death row inmates"? The report states:
These "volunteers" and "death row inmates" are farmers from Shandong to the northeast. Their place of residence was exactly the area where the First Route Army of the Northeast Anti-Japanese Coalition Army, led by General Yang Jingyu, operated. It is conceivable that the people killed by Kitano Masashi were heroic anti-coalition fighters and kind Chinese people.
Jing Guanhua, a former associate professor in the Department of Bacteriology at China Medical University, confirmed that when he was interning at Puppet Manchuria Medical University at the end of 1942, he heard Kitano's assistant Toyohiro Hamada say that it took too long to use ordinary animals for typhus experiments, because the military needed it, and people had been used for experiments.
It can be seen from this that the experiments of the Japanese invaders with living people were by no means confined to medical universities. The 13 innocents killed by Kitano were only a few of the countless victims.
