Serological markers of hepatitis A and B virus infection were determined by radioimmunoassay in 162 university students. Antibody to hepatitis B e antigen (anti-HBe) was demonstrated in 11 of 15 students positive for both antibody to hepatitis B e antigen (HBsAg) and antibody to hepatitis B core antigen (anti-HBc). The presence of anti-HBc alone seemed to denote previous hepatitis B virus infec...

We report a case of methimazole-induced acute hepatic failure, which occurred 17 weeks after initiation of the drug in a 43-year-old man with hyperthyroidism and hepatitis B surface antigenemia. Postmortem needle autopsy of the liver revealed an established micronodular cirrhosis secondary to hepatitis B with moderate septal/portal inflammation, marked cholestasis and scattered acidophilic bodi...

Background: Hepatitis B is the most common blood-borne viral infection that is considered as a major public health problem of the world's major health problems. The aim of this study was to investigate the prevalence of hepatitis B virus (HBV) infection among blood donors referring to blood transfusion centers. Methods: This retrospective cross-sectional study was performed on 216004 volunteer...

 Abstract Background: Investigators were suspicious of tyrosine-methionine-aspartate-aspartate (YMDD) mutations occurred only in patients who were treated by lamivudine. However, YMDD mutations of hepatitis B virus gene (HBV DNA) in patients with chronic hepatitis B (CHB) untreated with antiviral medicines was reported in some studies. The aim of this study was to evaluate YMDD mutations in Ira...

introduction: lichen planus (lp) is an inflammatory mucocutaneous disease with unknown aetiology. many studies have been reported regarding probable relationship between lp and liver diseases especially hepatitis b and c and they have a lot of different consequences. these studies evaluated the relationship between lp and hepatitis b and c in hajdaee dermatology clinic in kermanshah, from 2004 ...

The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...
