5th WAA Congress therapeutic artificial organs, 10 years after.

In 1983, more than 10 years ago, the concept of therapeutic artificial organs was proposed by this author. Currently developments of various types of immunomodulation technologies are well established, and therapeutic artificial organs for the treatment of autoimmunodiseases have become a well-accepted concept. It is this author's opinion that if we utilize apheresis technologies properly we should be able to prevent the aging process of mankind. Physical youth, and perhaps mental youth, can be achieved by apheresis technologies. However, in order to maintain youth and enjoy a high quality of life, it is essential to maintain a strong will to live. In this paper a new type of an artificial organ is proposed. This antiaging artificial organ is named "Juzo," the organ for a longer life, in Japanese, by this author.
