Significance of surface immunoglobulin in murine and human myeloma and chronic lymphocytic leukemia.
One important factor in the production of the immunologic deficiency in myeloma appears to be the alteration of the surface immunoglobulin by a macromolecular, RNA containing factor released by the tumor. In contrast, the cells of chronic lymphocytic leukemia are not influenced by factors outside the cell and their lack of immunologic reactivity is due to an intrinsic defect. These characterist...
coincidence of autoimmune diseases such as immune thrombocytopenic purpura (itp) with immunodeficiencies has been reported previously in patients who suffered from primary antibody deficiency (pad). but there is no original study on immunological profiles of itp patients to find out their probable immune deficiency. in this case-control study, itp patients’ humoral immunity was investig...
abortion traditionally means miscarriage and is still known as a problem, which societies have been trying to reduce its rate by using legal means. despite the fact that pregnant women and fetuses have been historically supported; abortion was firstly criminalized in 1926 in iran, 20 years after establishment of modern legal system. during next 53 years this situation changed dramatically, t...
Diabetes mellitus (DM) is a metabolic disorder resulting from a defect in insulin secretion, insulin action, or both (Kumar et al., 2002). In type 1 diabetes, the body does not produce insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. Insulin deficiency in turn leads to chronic hyperglycaemia with disturbances of carbohydra...
The general basic problems of homotransplantation are briefly reviewed; and pertinent aspects of the factors involved are applied to the corneal graft problem. It is pointed, out that one of the most important questions yet to be solved is the isolation and characterization of the antigens involved. The necessity for an in vitro technique to study this problem prompted the preparation of antico...
Acne vulgaris is a self-limiting skin disorder seen primarily in adolescents, whose aetiology appears to be multifactorial. The four main aetiological factors are hypercornification of the pilosebaceous duct, increased sebum production, colonization with Propionibacterium acnes, and subsequently the production of inflammation. Considerable investigation has addressed the immunologic reaction to...
BACKGROUND Infants of human immunodeficiency virus (HIV)-infected women have high mortality, but the immunologic integrity and protection afforded by the breast milk of HIV-infected women is unknown. METHODS We determined morbidity and mortality by 24 months among breast-fed infants of 588 HIV-infected and 137 HIV-uninfected women followed-up in a clinical trial in Botswana. A matched case-co...
BACKGROUND/AIMS Advanced human immunodeficiency virus (HIV) infection, despite sustained viral suppression by highly active antiretroviral therapy (HAART), is a risk factor for poor immunologic recovery. However, some patients with advanced infection do show immunologic recovery. In this study, predictive factors of immunologic recovery were analyzed in advanced HIV patients showing sustained v...
