HLA-A, -B, -DR and -DQ antigen profile was studied in pulmonary tuberculosis patients (n = 209) and their spouses (family contacts; n = 50) and healthy volunteers (n = 72). An increased frequency of HLA-A-10, B7, B15, DR2 and DQ1 was seen in the pulmonary-TB (PTB) patients when compared to the total control subjects (n = 122). However, a significant(More)
SETTING Influence of HLA-DR antigens and lymphocyte responses in pulmonary TB patients. OBJECTIVE To elucidate the role of HLA-DR genes/gene products on lymphocyte responses to Mycobacterium tuberculosis antigens and mitogens, the present study was carried out in pulmonary tuberculosis during active and cured stage of the disease. DESIGN Serological(More)
SETTING HLA and tuberculin status in pulmonary tuberculosis patients. Tuberculosis Research Centre, Indian Council of Medical Research, Madras, India. OBJECTIVE To elucidate the role of HLA-class-II genes/gene products on tuberculin reactivity in pulmonary tuberculosis patients. DESIGN Serological determination of HLA-DR and -DQ antigens was carried out(More)
Association of HLA-DR2 genes/gene products has been shown with pulmonary tuberculosis (PTB) patients in India. In the present study, the influence of HLA-DR2 and non-DR2 genes/gene products on immunity to tuberculosis has been studied. Plasma samples of -DR2 positive patients (active and inactive TB) showed a higher antibody titre to Mycobacterium(More)
SETTING Tuberculosis Research Centre, Indian Council of Medical Research, Madras, India. OBJECTIVE To elucidate the role of HLA-Class II genes/gene products on phagocyte enzymes such as lysozyme, beta-glucuronidase and acid phosphatase in the plasma of pulmonary tuberculosis patients. DESIGN Serological determination of HLA-DR and -DQ antigens was(More)
SETTING Tribal area in South India with a population of 96,000, where the tuberculosis case-finding activity was very poor. OBJECTIVES To investigate the feasibility of (1) involving literate (who can read and write) tribal youth volunteers for detecting cases of pulmonary tuberculosis (PT) in their respective hamlets; and (2) antituberculosis drug(More)
Many processes have been used for recycling of carton packaging wastes. The pyrolysis highlights as a promising technology to be used for recovering the aluminum from polyethylene and generating products with high heating value. In this paper, a study on pyrolysis reactions of carton packaging wastes and its pure components was performed in order to(More)
To understand whether the presence of cold reactive lymphocytotoxic antibodies (LCA) (reactive at 15 degrees C) in the system has any effect on immunity to tuberculosis lymphocytotoxic antibodies to adherent cells (enriched-B cells) and non-adherent cells were studied in active-TB (n = 42) and inactive-TB (cured) patients (n = 49) and healthy controls (n =(More)
