The effect of Byakko-ka Ninjin-to-on xerostomia in elderly patients and the relationship between the improvement of subjective symptoms and kampo diagnosis were studied. Xerostomia improved in 60 percent of 30 patients treated with Byakko-ka-Ninjin-to. There were significantly more patients who were less advanced in years and with a good constitution in the effective group than in the non-effective group.
Although the occurrence of appetiteoss was significantly higher in the non-effective group, there was no significant difference between the groups with respect to the occurence of constipation, diarrhoea, boborysmus, upper abdominal bloatedness or cold constitution. No significant differences between the groups were shown in the occurrence of oral kampo diagnosis such as bitter taste in the mouth, thirst, stickiness in the mouth, and mucosal dryness.
From these results it is concluded that Byakko-ka-Ninjin-to is effective for elderly patients who are not too advanced in year and who have a good constitution and (sthenia).

The general survey for the curricula of traditional medicine (TM) in medical, dental and pharmaceutical courses (Universities and Colleges) has been carried out in Japan.
In this survey, TM in medical specialist education has come to focus on the following items;
1) Execution of TM educational issues
2) Prospect of education
3) Courses should be introduced from now
As a result: more than half of the Universities which does not introduce TM state reason for shortning of School hours and lack of the teaching staff. The total percentage of Universities which already introduced or intended to introduced TM soon exceed 37%. In medical and dental courses, TM will be introduced in clinical medicine as well as an optional subject. On the other hand, TM will be introduced as a postgraduate curriculum and optional subject in pharmaceutical courses.

The general survey for the curricula of traditional medicine (TM) in medical, dental and pharmaceutical courses (Universities and Colleges) has been carried out in Japan.
In this survey, TM in medical specialist education has come to focus on the following items;
1) A status of the introduction of TM in the curricula of medical, dental and pharmaceutical courses respectively
2) A comparision of the above status between public and private courses
3) Contents of the curricula of traditional medicine
4) An analysis of education system and contents in the medical specialist education
It was shown that TM education has been introduced 26% of the universities and the rate of introduction was higher in private universities than that of public.
Other statistical results of the survey are presented in this report.

Quantitative specification of color of the tongue was performed by chroma meter (Minolta CR-100) according to the Commission Internationale de l'Eclarirage 1976 (L*a*b*) Space, the color was analyzed with digital expressions as L* (value), a* (hue of red-green), b* (hue of yellow-blue) and c* (chroma) values.
The difference of the color of the tongue of the patients before and after administration of herbal medicine extracts for 12 weeks was detected by the chroma meter with statistical significance. The change of the color of the tongue of a diabetic female was also able to record on the course of the cerebrovascular accident.
To analyze the correlation between these quantified values and the findings of the tongue by inspection, 116 patients were devided into four groups (whitish, red, dark and violet) according to the color of the tongue by inspection. Most patients in the violet tongue group showed small b* value. As a group the violet group showed significantly smaller b* value than those of the whitish, red and dark groups. In the L*a*b* space as the b* value becomes small the hue becomes blue.
Analyzing the relationship between the diabetic retinopathy and the b* value, color of the tongue of 21 diabetics was examined by the chroma meter. As the result eight patients with diabetic retinopathy indicated significantly smaller b* value than those of 13 patients without retinopathy.
These obsevations suggest that the color of the tongue would be able to specificate quantitatively by chroma meter, the value measured would be correlated to the finding by inspection of the tongue, and that diabetic retinopathy would related with the hue of blue of the tongue detected by this specification system.
