JOURNAL FREE ACCESSThis last paper of the present review described some immunological and pathological aspects of host lipids in tuberculous infection as supplements to the preceding three papers. And last of all, the evolution of tuberculous infection was briefly discussed as a phenomenon involving with lipid degradation of the host cell membrane, which might in turn affect the status of infecting tubercle bacilli.View full abstractDownload PDF (1011K) -

JOURNAL FREE ACCESSMacConkey's agar medium and hydroxylamine egg medium were compared for differentiating strains of the Mycobacterium fortuitum complex from other rapidly growing mycobacteria.
Only 40% of the strains of M. fortuitum and one half of the strains of M chelonei subsp. abscessus could grow on the MacConky's agar plates or slants, although the procedure described in the Manual of Clinical Microbiology (1974) has been used faithfully. In addition, about one half of the strains of M. smegmatis grew on this medium.
In contrast, all strains of the M. fortuitum complex grew on the hydroxylamine medium (0.5 mg/ml NH2OH·HCl). However, one half of the strains of M. smegmatis and all strains of M. chitae grew on this medium. On the hydroxylamine medium (0.75 mg/ml), 80% of the strains of M. fortuitum, 92% of the strains of M. chelonei subsp. abscessus could grow, while about 50% of the strains of M. chelonei subsp. chelonei failed to grow on it. All other strains did not grow on this medium.
The hydroxylamine medium (0.5 mg/ml and 0.75 mg/ml) appeared to be more suitable for differentiating the strains of the M. fortuitum complex from other rapidly growing mycobacteria than did the MacConkey's agar. As stated previously by the present authors (7), it is required to use a combination set of three or more tests to make a complete differentiation.View full abstractDownload PDF (564K) -

JOURNAL FREE ACCESSImmunological studies were carried out on patients with intractable pulmonary tuberculosis to evaluate the background factors of intractability.
Twenty-one cases who failed to convert to bacilli negative by previous treatment and who had the F (far advanced cavitary) type of Gakken classification on chest X-ray film were designated as intractable pulmonary tuberculous patients. The controls were twenty-seven cases of tractable pulmonary tuberculosis with negative bacilli and BC (cases infiltrative) type of Gakken classification, and a group of healthy subjects. In comparison with the controls, the intractable pulmonary tuberculosis patients showed the following characteristics: (1) A depression of the delayed type hypersensitivity (DTH) reaction to dinitrochlorobenzen (DNCB), (2) A decrease in the number of monocytes and lymphocytes in peripheral blood, (3) A depression in the interaction between monocytes and lymphocytes, (4) A decrease in the number of T-lymphocytes and early T-lymphocytes, and (5) An increase in the number of IgG-FcR (+) T-lymphocytes. On the other hand, the number of B-lymphocytes and IgM-FcR (+) T-lymphocytes, immunoglobulin levels in peripheral blood, and DTH to PPD were similar to those of the controls. Monocyte functions were almost the same as in the controls with respect to phagocytosis, nitroblue tetrazolium (NBT) reduction test, and lysosomal enzyme levels.
These results suggest that non-specific immunity of intractable pulmonary tuberculosis patients is depressed in cell-mediated immunity, but not in humoral immunity.View full abstractDownload PDF (1170K) -

JOURNAL FREE ACCESSA 35-year-old male suffering from small-cell carcinoma was misdiagnosed as lung tuberculosis for about 4 months initially, because of rapid improvement of clinical symptoms, improvement of laboratory data and certain regression of shadow on chest X-ray observed as a result of combined use of anti-tuberculous drugs including rifampicin 450 mg daily. The patient died of pulmonary cancer one year later, and the effects of RFP on tumor were also discussed briefly.View full abstractDownload PDF (10456K)
