background it is important to differentiate whether isolated anti-hbc is due to false positive results or the prior exposure to hepatitis b virus, because individuals with false-positive anti-hbc can benefit from vaccination and their blood can be safely transfused. to distinguish between these two conditions, we evaluated the serologic response to hepatitis b vaccine. methods ninety subjects w...

background: 1.3% of people in iran are positive for anti-hbc antibody.the objective of this study is to determine the rate of seroconversion in those with persistent isolated anti-hbc after vaccination. materials and methods: in a quasi-experimental study, 94 persons with isolated anti-hbc antibody who were referred to tehran blood transfusion organization between 2002 and 2004 were selected th...

background: the outcome of hepatitis b virus (hbv) infection is chronic or resolved hbv infection. over the time, the levels of hbsag or anti-hbs declined and were not detectable in their sera and was named as isolated anti-hbc. the purpose of this study was to assess the prevalence of isolated anti-hbc in previously hbv infected individuals.methods: from april 2000 to september 2008, the resul...

Luteolin and delphinidin are the flavonoids with known protective roles. They inhibit genotoxic effects induced by halogenated boroxine (HB) in vitro. Statistically significant decrease frequency of micronuclei nuclear buds suppression occurrence aberrant cells were observed before, but mechanism its anti-genotoxic activity is still not clear. In our experiment we aimed to quantify HB on relati...

UNLABELLED The long-term protection of hepatitis B (HB) vaccination has been debated for years. The purpose here was to evaluate the kinetic changes of antibody to HB surface antigen (anti-HBs) and define immune memory of the HB vaccine among college students who had previously received full neonatal immunization against HB. In all, 127 college students aged 18-23 years born after July 1984 who...
