Inclusion Criteria

1) Patients who give written consent of its free will to join the study
2) Patients who are not younger than 20 and not older than 90 when the consent obtained
3) Patients diagnosed as multidrug resistant pulmonary tuberculosis who do not respond to treatment by multiple chemotherapies or cannot continue the chemotherapies (WHO definition : resistant to both of INH and RFP) and no other recommended treatments can be selected. Or (1)tuberculosis patients to whom both of INH and RFP cannot be administered due to resistance or side effects, or (2)tuberculosis patients to whom RFP cannot be administered due to resistance or side effects and the risk of treatment failure is high due to there are 3 or less drugs that can be administered, and no other recommended treatments can be selected.
4) Patients with multidrug resistant pulmonary tuberculosis from whose clinical respiratory specimen culture (sputum, bronchoscope specimen, gastric juice) mycobacterium tuberculosis resistant to both of INH and RFP is detected within 6 months before the registration and continue to culture positive at the registration. (Being positive in culture within 60 days of registration)

(Being positive in culture within 60 days of registration)
5) Patients whose PaO2 is not less than 70 mmHg or SpO2 is not less than 93 percent on room air
