altogether, 120 rodents of 4 species were trapped alive in various parts of meshkin-shar district where visceral leishmaniasis is endemic. 13 of them were cricetulus migratorius (gray hamste) that all were caught inside the living rooms. nine of them showed leishmania antibody in titers of ≥ 1:100 in direct agglutination test (dat) and amastigotes were found in the spleen smears of 2 cricetulus...

in the present study the distribution of rubella hemagglutination inhibition (hi) antibody titer in the sera of 1486 women of 18 to 25 years old residing in tehran were examined. sera were pretreated with acid washed kaolin and pigeon red blood cell. titers below 1:10 and in some studies below 1:20 are considered nonimmune to rubella. our results show that 10, 29% of studied population had hi a...

Background: Patients with end stage renal disease have higher incidence of infection dis-eases that is thought to be related to impaired immune system. Objective: To determine the antitetanus IgG antibody level in Iranian hemodialysis patients with end stage renal disease and to find its association with sex, age, blood hemoglobin, serum albumin, dura-tion of dialysis, time of dialysis per week...

A passive hemagglutination (PHA) test for measles was evaluated in comparison with hemagglutination inhibition (HI) and neutralization (NT) tests. The PHA test determines exclusively the level of antibody directed to the hemagglutinin protein of measles virus. The ratio of PHA to HI titer was 1 to 32 (geometric mean, 6.5) for the first 5 weeks of infection but declined to near unity thereafter....

erythropoietin (epo) was first known as a factor for red blood cell proliferation and differentiation. recent studies show the effects of epo on immune system. in this study the antihuman leukocyte antibody (anti-hla) titer were determined in five groups of rats, which had been sensitized with human lymphocyte. also, the effects of stimulation's frequency and dose of recombinant human eryt...

Vitamin E and selenium are considered as immune boosting agents. The present study was designed to evaluate effect of vitamin E and selenium on antibody titer against to hemorrhagic septicemia (HS) vaccine. Twenty unvaccinated buffalo calves (two to four month old) were randomly selected and divided into four groups (group A, B, C and D); and each group contain five calves. Group A was control;...

background: selective antibody deficiency with normal immunoglobulins (sadni) may be identified as part of distinct primary or secondary immunodeficiency disorders. the clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. objectives: to evaluate sadni in patients with recurrent sinopulmonary infections and its relation to igg subclas...
