Background: Hepatitis B (HB) is one of the main health problems. Over 400 million people worldwide have been evaluated as infected patients or chronic carriers. Health care workers (HCWs) are of higher risk for infectious diseases including HBV infected patients. This study aims to evaluate the rate of HBS antibody among the HCWs of Shahid Sadoughi Burn hospital in Yazd. Methods: This cross...
BACKGROUND/AIMS We investigated the impact of the baseline anti-A/B antibody titer on the clinical outcome in ABO-incompatible kidney transplantation (IKT). METHODS We included 183 patients who had undergone KT (40 ABO IKT and 143 ABO-compatible KT). Eight patients with a baseline titer of ≥1:512 were assigned to the high-titer group and 32 patients with a baseline titer of ≤1:256 were assign...
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...
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 erythropo...
Background and purpose: Ôf the agents involved in stroke, is presence of antiphospholipid antibody in serum of the patients. Ïn recent years, in addition to cardiolipin antibody (aÇL) another antiphospholipid antibody (aPL) was identified as the predispousing factor of stroke. Ïn the present study, in addition to the identification of higher than normal level of aÇL and aPL, prevalence rate o...
