Enterotoxigenic Escherichia coli (ETEC) is the most common cause of diarrhea in children in developing countries and among travelers to ETEC endemic areas. ETEC diarrhea is caused by colonization of the small intestine mediated by colonization factor (CF) antigens, and subsequent elaboration of enterotoxins. Breast feeding has been related to protection against enteric infections. The protectiv...

The functional maturity of T and B lymphocyte populations from human newborns was evaluated using a reverse hemolytic plaque assay to detect immunoglobulin-secreting cells generated in in vitro cultures stimulated with pokeweed mitogen (PWM), a T cell-dependent polyclonal activator, and the Epstein-Barr virus (EBV), a T cell-independent B cell activator. Cord blood lymphocytes failed to produce...

This enzyme immunoassay for specific measurement of secretory immunoglobulin A concentrations in human serum involves use of a small chromatographic column as a solid-phase. Serum samples are incubated for 2 h with beta-D-galactosidase-labeled antibody to secretory component, then passed through a 0.1-mL Sepharose 4B column containing antibodies to human immunoglobulin A. After the column is wa...

The quantitation of immunoglobulins in human sera is a common procedure in clinical laboratories and is useful both for clinical and research purposes. Several papers have been published on the subject. Because significant age-related changes occur before adult life, most reports deal with immunoglobulin values in normal children (1-4). However, the data from different laboratories are difficul...

atopic dermatitis is one of the most common allergic diseases that almost always respond to conventional therapies with topical emollient, topical corticosteroids, systemic antihistamines and allergic abstinence. however few cases of atopic dermatitis with severe course do not respond to conventional therapies and high dose of intravenous immunoglobulin or cyclosporine are recommended for them....

The adhesion of Escherichia coli to human urinary tract epithelial cells was inhibited by commercial gamma globulin, the total immunoglobulin fraction of human breast milk and urine, as well as the isolated immunoglobulin G and secretory immunoglobulin A fractions of urine from patients with acute pyelonephritis. Urinary anti-O6 antibodies reduced the adhesion of several O6 strains. Absorption ...

background: hyperbilirubinemia, or jaundice, is a life threatening disorder in newborns. it is a multifactorial disorder with many symptoms. generally, the physiological jaundice is the most prevalent type however in some regions pathological jaundice is also common. this review article focuses on a brief introduction to jaundice, its types and causes, measuring the bilirubin level, clinical ap...

b ac k gro und : atopic dermatitis (ad) is a prevalent chronic disease in children aging from 6 months to 12 years old. recent studies have shown a positive effect of prebiotics in the prevention and treatment of ad. the mechanism of this effect has not been clearly established. the objective of this study was to investigate the effect of supplementation of prebiotic on serum immunoglobulin e (...

schizophrenia is a mental disorder painful with prevalence of about 1% in the world.  nowadays, there is no experimental test aiding the accurate diagnosis of schizophrenic patients but recently quantitative determination of some serum proteins led to many investigations on the roles of these in neuropsychiatric.in the present study, our aim is to quantitative determination apoa1 and igm betwee...
