Because measles-specific antibody titer after vaccination is lower than after natural infection, there is concern that vaccinated persons may gradually lose protection from measles. To examine the persistence of vaccine-induced antibody, participants of a vaccine study in 1971, with documentation of antibody 1-7 years after vaccination, were followed up in 1997-1999 to determine the presence an...

Background: Platelets can activate B cells and stimulate them for the production of antibodies. Since platelet microparticles (PMPs) originate from platelets, they may have the same virtue. In the present study, the effect of PMPs was investigated on the production of human leukocyte antigen (HLA)-specific antibody from B cells in vitro. Materials and Methods: In this experimental study, HLA-D...

P ositive islet cell–related autoantibody is thought to reflect the process of immune-mediated -cell damage symbolized by the insulitis, but there have been few reports on the pancreas histology of latent autoimmune diabetes in adults (LADA). We report a study of pancreas histology and a longitudinal insulin secretion in a LADA patient. A 50-year-old woman treated with sulfonylurea from the age...

Evaluation of Two Sources Plant Antioxidants on Antioxidant Status, Morphology Changes the Jejunum, Antibody Titer Against Influenza and Growth Performance Broilers

background: hepatitis b virus (hbv) fails to produce appropriate immune responses in some healthy individuals; thus, different strategies have been adopted to promote immune responses. the current study aimed at evaluating the efficacy of hbv vaccine coadministered with tetanus-diphtheria (td) vaccine compared with hbv vaccine in healthy individuals through measuring hepatitis b surface antibod...

Background: Toxoplasmosis is a zoonotic disease with high seroprevalence worldwide. Several immunological methods have been described for diagnosis of toxoplasmosis. Objective: To determine the parasitemia period in patients infected with toxoplasma using PCR and comparing serological data with molecular results. Methods: 154 serum samples from patients with toxoplasmosis were examined. Presenc...

Since the ordinary tests for diagnosis chronic amebic colitis looks to be unsufficient. We try to design the following study. Our study seeks the importanc.;e of "IFA" (Indirect Immuno Fluorescent Aniti body). Among 145 patients with amebic colitis Entamoeba hystolitica observed with reapeted and specified tests. In searh of serologic tests, antibody range in 20 patients who had amebic coliti...
