Experiments on human beings is essential to medical science and to medical treatment. However, since there is neither the consent of the subject to do it nor the legislation or the guide line for the medical experiments targetting on human beings in our nation, those experiments has caused more and more cases where the human rights and life rights of the subject and patients are invaded, and the word "experiment on human being" itself has been converted into a taboo word.
There is a case of a millitary medical experiments on human beings that is quite outrangeous and against humanity. "the 731 unit"--the unit that did experiments on human beings such as Chinese political prisoner, captives, and so on-- was not impeached thanks to the deal of Japan with. American millitary, while the Nazi was convicted on the International Millitary Trial. Nazi was only convicted by the Khabarovsk Trail by the old soviet, partly.
Medical crimes committed by the Japanese army should have been adjudicated, and the ethical criteria of experiments on human beings as aresult of the regret of medical expert should have been made.
