Isotypic discordance of paraproteins and lymphocyte surface immunoglobulins in myeloma.
B lymphocyte surface immunoglobulins (Smlg) were studied in 24 patients with multiple myeloma by means of anti-isotypic antisera, and their heavy and light chain isotypes were compared in each patient with those of the paraprotein. In 21 patients, lymphocyte Smlg consisted of only one light chain type, and in 16 of only 1 heavy chain type. However, the Smlg and paraprotein heavy and light chain...
متن کاملLymphocyte subpopulations and surface membrane immunoglobulins in myasthenia gravis.
Lymphocyte subpopulations were studied in 16 myasthenic patients by means of E and EA7s rosettes and surface membrane immunofluorescence. Myasthenic patients showed an increase in lymphocytes with surface IgM an IgD when compared to a control group. In female patients this increase was highly significant, and lymphocytes bearing membrane IgG and IgA were also augmented. No difference was found ...
متن کاملIsolation and Partial Characterization of Lymphocyte Surface Immunoglobulins
Immunoglobulins were isolated from the surfaces of lymphocytes from a variety of lymphocyte populations including murine and human thymus lymphocytes and murine spleen and thoracic duct lymphocytes. Cell surface proteins were labeled with iodide-(125)I by lactoperoxidase-catalyzed iodination, and recovered in solution either by solubilization in dissociating solvents or active metabolic release...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Role of Suppressed Immunoglobulins in Outcome of Patients With Multiple Myeloma
Introduction: Multiple myeloma (MM) is typically presented with abundant monoclonal secretion of one type of immunoglobulin. The other classes of immunoglobulins, which are uninvolved and not secreted by malignant plasma cells, could be decreased. A number of previous studies reported the effect of suppression of uninvolved immunoglobulins on the outcome of patients with myeloma. However, its e...
