We got the following result on investigation of the present status of the experiment from Jan. 1956 to Dec. 1963.
1) The experimental articles increased and became complicated year by year.
2) About 50% of all the experiments were the bacteriological experiments. Besides, About 90% of those were experiment of tubercle bacilli.
3) Among the experiments of tubercle bacilli the drug resistance determination of anti-tuberculous agents was 5.4% in 1956. But it increased year by year, and reached to 14% in 1963. It increased as about three times as the first in eight years.
4) We determined only the drug resistance of the primary anti-tuberculous drugs between 1953 to 1956. But we began the drug resistance determinations of the secondary anti-tuberculous drugs in 1960. And it occupied 43.3% of the drug resistance determinations in 1963.
5) There were a few drugs unfit for “Ogawa Medium” among the secondary anti-tuberculous drugs when we determined the drug resistance, and the experiment has become complicated And we should try to discover the secondary reactions as fast as possible through the various basic experiments before we use new drugs.
