The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

coincidence of autoimmune diseases such as immune thrombocytopenic purpura (itp) with  immunodeficiencies has  been  reported  previously in  patients  who  suffered  from primary antibody deficiency (pad). but there is no original study on immunological profiles of itp patients to find out their probable immune deficiency. in this case-control study, itp patients’ humoral immunity was investig...

background: antibody production in patients with end-stage kidney disease impairs due to several mechanisms. there are different ways to improve response rate to hepatitis b (hb) vaccine. in this study we evaluated the effect of tetanus-diphtheria toxoid (td) vaccine on hbs antibody (ab) level while being given simultaneously with hb vaccine.  methods: we recruited 43 hemodialysis and 20 perito...

Antigenic differences between certain inbred strains of mice which could not be revealed by hemagglutination techniques were readily disclosed by lymphocyte cytotoxicity. With an improved cytotoxicity test lymphotoxic titers were as high as 1:512 with non-hemagglutinating A anti CBA antisera. In other mouse strain combinations, a close parallel of both types of antibody activity was obtained. T...

Background: The antibody response to hepatitis B surface antigen (HBsAg) controls hepatitis B virus infection. The "a" determinant of HBsAg is the most important target for protective antibody response, diagnosis and immunoprophylaxis. Mutations in this area may induce immune escape mutants and affect the performance of HBsAg assays. Objectives: To construct clinically relevant recombinant muta...

this study was conducted to evaluate the effect of different levels of electrolyte dietary balance (deb) on performance and immune function of broiler chickens reared under the heat stress condition. three hundred oneday chickens were distributed randomly in 25 separate pens with 12 chicks in each. this experiment was in the form of a completely randomized design with five treatments and five r...
