conclusions the present study showed that g-csf is not superior to placebo in production of protective antibody titers after hbv vaccination but could result in a more rapid antibody response, compared to the placebo. results there was no statistically significant difference between anti-hbv antibody titers in patients receiving double dose hbv vaccination plus g-csf and patients receiving doub...

Background: In addition to passive immunotherapy using anti-HER2 monoclonal antibodies, active immunotherapy via HER2 targeting is an interesting approach to inducing specific anti-tumor immune responses. We have recently reported the immunogenicity of HER2 subdomains following DNA immunization and HER2 protein boosting. In the present study, we evaluated the immunogenicity of different HER2 ex...

background: hepatitis b is an important infectious disease.  since several years ago, mass vaccination against this viral infection has become as part of routine vaccination schedule of iran.  however, some healthy neonates, children and adults fail to generate a protective antibody response after vaccination. objectives: to investigate distribution of hla class-i and class-ii antigens in healt...

Background: Erythropoietin (EPO) was first known as a factor for red blood cell proliferation and differentiation. New studies show the effects of EPO on immune system. Objective: In this study, the effects of pretreatment with recombinant human erythropoietin (rHuEPO) on the anti-human leukocyte antibody (anti-HLA) titer were determined. Methods: Three groups of rats were sensitized with human...

introduction: zinc deficiency causes abnormalities in immune response. in chronic hemodialysis (hd) and continuous ambulatory peritoneal dialysis (capd) patients, impaired immune responses to vaccination have been reported. therefore, we performed a study to determine the correlation between serum zinc levels and immune response to hepatitis b vaccination in patients on dialysis. methods: a cro...

Background & Aim: The recent study was conducted to investigate the effects of Thyme extract in drinking water on immune response of broiler chickens. Experimental:  A total of 245 day-old broiler chicks were purchased and 20 chicks were bled for determination maternal antibody and remaining chicks divided into 5 equal groups. Chickens of group A, B and C received 0.1%, 0.15% and 0.2%...
