common variable immunodeficiency (cvid) is a heterogeneous group of disorders, characterized by hypogammaglobulinemia and increased susceptibility to recurrent infections, autoimmunity and malignancies. we have previously shown that some pediatric patients with cvid can respond to meningococcal polysaccharide vaccine. twelve pediatric cases with cvid were re-evaluated to determine whether bacte...

there are few published reports on epidemiological studies concerning rubella in iran. the level of antibody in vaccinated individual’s declines gradually and the chances of infection in these people are much greater to those naturally immunized by infection. therefore, it seemed logical to determine the level of antibody in non vaccinated female students, aged from 18 to 26 years of isfahan un...

background and aims: human parvovirus b19 may transmit to the fetus via the placenta during pregnancy and cause serious complications such as severe fetal anemia, non-immune hydrops fetalis, and even intrauterine fetal death. the aim of this study was to determine the seroprevalence of parvovirus b19 antibodies among young women, sanandaj, iran. materials and methods: ninety young women (15-40 ...

background:infection of mothers with rubella virusduring pregnancy can be serious; if the mother is infected within the first 20 weeks of pregnancy she is likely to have miscarriage, stillbirth, or baby with congenital rubella syndrome. this study was carried out to define rubella virusseroprevalence in pregnancy in osogbo, nigeria. methods:this study is a cross-sectional sero-survey of rubella...

background: anti-ganglioside antibody assays are widely used for diagnosis of autoimmune peripheral neuropathies. objective: this study aimed to determine serum levels of anti-ganglioside antibodies in children with guillain-barre syndrome by immunoblotting technique and compare the results with those obtained by elisa method. method: in this investigation, 50 children with guillain-barre syndr...

objective: to evaluate the importance of cytokine type in embryo implantation in uterus specified and activated macrophages interfere the tube movements and embryo retention in uterine tubes by smooth muscle relaxation and disrupting ciliary function. therefore, increased risk of infection with hp during pregnancy, we investigated relation between helicobacter pylori (hp) infection and prevalen...

objectives: ctxb (cholera toxin b subunit) contributes to a vaccine's efficacy by stimulating production of the anti-ctxb antibody. various attempts have been made to increase production of this antibody. chitosan is a mucoadhesive polysaccharide that has tremendous potential for oral vaccine delivery in terms of its exclusive features that include biocompatibility, biodegradability, high charg...

objective: pseudomonas aeruginosa is the major cause of septicemia and wound infection in burned patients. immunotraphy is the best practical way for prevention and treatment of these infections. flagella as one of the most important bacterial virulence factors has important role in attachment, motility, chemotaxis and tlr-5-dependent immune response so that it propounded as a vaccine candidate...

the objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51su. the four antigen preparations for immunization ofbalb/c mice were: cl: blv-flk cell lysate, uf: a fraction of cl (between 30 and 100 kda), wvp: wholevirus particles and sp: with ion exchange chromatography, gp51su was semipurified. a total of ninesucce...
