Since January 1949 one hundred and five patients with pulmonary tuberculosis were found out by the mass-screening examinations, and they were treated by the chemotherapy and/or surgical operation. Roentogenographic recurrence or exacerbation of those patients after the termination of the treatment were traced until July 1960, and the following results were obtained.
1) In the chemotherapy 7 exacerbations out of 76 cases, 9.2%, and in the surgical operation 4 exacerbations out of 29 cases, 13.8% were observed. The annual recurrence rate was 3.6% in the former and 2.6% in the latter.
2) The recurrence rate by working conditions showed 20.7% in the light physical work group (mainly desk workers) and 0% in the medium physical work group (mainly physical workers) respectively, after the chemotherapy. Apparently more recurrences were observed in the former. After the surgical operation the recurrence rate was 15.4% in the former group and in the latter it was 12.5%.
3) According to the results obtained it is likely concluded that the physical workers would have better prognosis of pulmonary tuberculosis rather than desk workers as far as our mill is concerned where they work under relatively favourable environment from the socio-economical point of view.
