Owing to the fact that the Donaggio reaction of urine is likely to show degrees of fatigability, I applied this test to determine the capacity of work prescribed to the tuberculous patients.
Method of study: The original Donaggio method was used to confirm the Donaggio value. However, the actual determination of D, value for the patients was done by Yokomichi, Sato and others' modified methods.
In 80 patients who were under occupational therapy, D, value was examined for a period of one and half years by testing urine every morning on rising, before and after the allotted working hours, and after dinner.
The results are as follows:
1) On investigation of 496 cases of tuberculous patients and together 117 healthy pasons as control, it was found that patients under therapy showed higher index figures than the general tuberculous patients.
2) On continual observations of D. index on each patient following average figures were obtained. The group of patients who worked one hour gained 2.5 after the work, two hours 2.4, four hours 3.4, six hours 5.4, and eight hours 4.9. Thus it is evident that the length of working hours does not always correspond to the increase of D. value. However, in the control whose assigned work was one hour showed 1.3, two hours 1.4, four hours 1.9, six hours 3.9, and eight hours 3.8. Thus the D. value showed a gradual elevation; for instance fatigue ration of eight hour work was only three times that of two hour work. Furthermore there were no significant differences between the ratio of one and two hours, and also six and eight hours.
3) According to the variations of D. value at different intervals as mentioned above I ordered the patients to shorten or to discontinue their work depending on the change of D. value
