The Oriental medical therapies are increasingly used in medical treatment in conjunction with the Western medical health care system in our country. As Oriental medicine and Western medicine are based on different scientific systems, there is no curriculum of Oriental medicine in Western medical school education. In 1996, we investigated opinions about Oriental medicine among medical students and teachers at Showa University. A mini follow-up survey was done in 1999 and 2000. Awareness of Oriental medicine was still limited, but those surveyed were remarkably interested in Oriental medicine. Moreover, they recognized Oriental medicine as an important and useful tool for the care of illnesses that do not respond to Western medicine. About 40% of the medical doctors at Showa University hospitals used Oriental medicine with their patients in 1996, and traditional knowledge was learned in its own way. According to the pharmaceutical department of Showa University, both the number and variety of Kampo prescriptions increased between 1996 and 2000. These results suggest that it is necessary to properly learn Oriental medicine from the foundations during medical school. More research on Oriental medicine in terms of clinical and basic science is necessary, and the opportunity to exchange information about Oriental medical diagnosis and treatments should be included in postgraduate curricula.

Scientific elucidation of “oketsu (blood stasis)” states is very important to understanding the diagnostic methods of oriental medicine. We investigated the correlation of blood fluidity to oketsu states, by micro channel array flow analyzer (MC-FAN). Twenty-seven female patients were divided into three groups: a non-oketsu group, a mildly affected group, and a severely affected group according to the diagnostic criteria of their oketsu syndrome. Immediately after collecting their venous blood, whole blood passage time was measured by MC-FAN. And we compared and investigated the correlation with degree of oketsu state, diagnostic criteria and changes of whole blood passage time after the administration of ku-oketsu drugs. As a result, whole-blood passage time of the mildly affected group and the severely affected group were significantly longer than that of the non-oketsu group, while the [an] improvement of blood fluidity was observed after medication. This study confirms that reduced blood fluidity is seen using MC-FAN in oketsu states, and that ku-oketsu drugs are able to improve these states.
