Cryostat sections of skin and nerve lesions of leprosy were stained with monoclonal antibodies recognising Mycobacterium leprae antigens and indirect immunofluorescence. In both the tuberculoid and lepromatous lesions, PGL1, 55-65-kDa, 17-kDa protein antigens and cross-reactive non-protein antigens were present. 65-kDa antigens were seen mainly in the skin(More)
A study was made on the in situ characteristics of dermal infiltrates in the early and late lepromin reaction with monoclonal antibodies defining T cell subsets, Langerhan cells and Ia like antigens. The early reaction (24 hrs) was elicited either with standard Dharmendra lepromin or leprosin-A and the late reaction (3-4 weeks) was elicited with standard(More)
A study was made on the in situ characteristics of dermal infiltrates in a 24-hr skin reaction using monoclonal antibodies defining T-cell subsets, Ia-like antigens, Langerhans' cells, My1, and indirect immunofluorescence. The skin reaction was induced by the mycobacterial antigen My1 derived from Mycobacterium leprae. In all, 10 biopsies were studied. The(More)
Cryostat sections of dermal lesions from 13 untreated patients of leprosy were studied by indirect immunoperoxidase using monoclonal antibodies (MLO4 & MLO6), defining M. leprae specific antigens. The lymphocytes and macrophages in both the tuberculoid and lepromatous granulomas showed membranous staining with the above antibodies. M. leprae organisms in(More)
Ultrathin sections of the peripheral nerves taken from three lepromatous leprosy patients (One untreated, other treated and third in ENL reaction) was examined in the electronmicroscope. In the untreated patient, solid M. leprae organism inside the schwann cell and the degeneration of schwann cell was seen. In contrast, the treated patient showed the(More)
There is a tendency to compare the results of surgery with that of oral corticosteroid therapy in leprous neuritis as if the two are competing methods. Surgery helps by removing the external compressive force and improves circulation so that steroids can reach and effectively act at the site of inflammation, minimizing the ischaemic and compression damage(More)
An assessment has been made of 108 neuritic leprosy patients to find out if the number of affected nerves and the clinical presentations of these patients give any indication of the underlying severity (classification) of the disease. Detailed clinical recordings, skin smears, lepromin testing with Dharmendra antigen, and a leukocyte migration inhibition(More)
Soft cystic swellings are noticed in leprosy patients during the course of disease and are seen all through the spectrum. The commonest site for these is the dorsum of wrist. At times these are seen over the dorsum and the lateral aspects of ankle as well. These contain straw colored sticky but clear fluid. On exploration these appear to arise from the(More)
Immunohistological analysis of infiltrates of nerves in patients with neuritic leprosy was carried out using monoclonal antibodies defining T cell subsets, Langerhans cells, HLA DR antigens, and indirect immunofluorescence. In all, eight nerves were analyzed. 2 of the 8 nerves showed epithelioid cell granulomas surrounded by large numbers of lymphocytes.(More)
