Colostrum provides newborns with nutrients and immunoglobulins that play a major role in the immune system. In this survey, immunoglobulin G (IgG) content, gross composition, mineral fatty acid composition were determined colostrum of Valle del Belice ewes aim evaluating effect lambing season. total, we analysed 60 bulk tank samples taken after during two seasons (summer winter). The IgG conten...

to study the humoral immune response to entamoeba histolytica infection, sera prepared from different cases of amoebiasis from gastroenterology ward of b.h.u hospital, including15 cases with amoebic liver abscess (ala), 10 cases with acute amoebic dysentery (ad) and 10 controls were examined by enzyme linked immuno sorbent assay (elisa), using crude amoebic antigen prepared from entamoeba histo...

The in vivo localization of radiolabeled heterospecific antibody to carcinoembryonic antigen (CEA) was inves tigated in a human colonie tumor-hamster host model. With the paired-labeled antibody technique, a significant and specific accumulation of goat anti-CEA immunoglobulin G (IgG) was observed in small tumors (<5.0 g) l day after injection. The level of anti-CEA IgG in the tumor sub sequent...

Background: Beta-thalassemia major is one of the major health problems in our country. Many studies have confirmed the fact that, these patients have an increased susceptibility to bacterial infections. Objective: In this study, we have assessed the humoral immune system in 68 thalassemic patients by measuring their serum concentration of Immunoglobulin G (IgG), IgM, IgA, C3 and C4 in order to ...

The primary antibody deficiency syndromes are characterised by recurrent respiratory tract infections and the inability to produce effective immunoglobulin (Ig) responses. The best-known primary antibody deficiencies are common variable immunodeficiency (CVID), X-linked agammaglobulinaemia (XLA), immunoglobulin G (IgG) subclass deficiency, and selective antibody deficiency with normal immunoglo...

The aim of the present study was to investigate the presence of anti-fibroblast antibodies in patients with idiopathic or scleroderma-associated pulmonary arterial hypertension (PAH) and healthy controls. PAH was documented by right-heart catheterisation (mean pulmonary artery pressure at rest >25 mmHg). Serum immunoglobulin (Ig)G and IgM reactivities of patients with idiopathic PAH (n = 35), s...

Methods for preparing bentonite-gamma globulin complexes and for determining their attachment to cells in tissue culture were investigated by use of human immunoglobulin G (IgG) labeled with 125I. For virus-inhibition studies, bentonite-IgG complexes were prepared by use of human IgG with high specific neutralizing activity against coxsackievirus A21. Much of the antibody in the complex remaine...

Two hundred and thirty strains of various gram-positive cocci were tested for quantitative, nonimmune binding of radiolabeled human polyclonal immunoglobulin G (IgG). The majority of coagulase-positive staphylococci and streptococci belonging to serogroups C and G showed a high uptake of IgG. The binding of immunoglobulin to group A streptococci was considerably less, with a number of strains c...

A factor present in normal rabbit sera enhanced the neutralization of the infectious complex of poliovirus with the pepsin Fab' fragment of rabbit immunoglobulin G (IgG) antibody but showed no activity for the infectious complex of the same virus with IgG antibody. The factor was associated with IgG, and its activity was inhibited by the pepsin Fab' fragment of normal rabbit IgG. The data sugge...
