understanding of the natural history of chronic hbv infection is useful for presenting the optimal management of chronic hbv infection. the aim of this study was to evaluate the natural history of chronic hepatitis b infection.in this cross sectional study, 219 untreated chronic hepatitis b patients from jan. 2010 to aug. 2012 were included. the subjects were classified in four groups based on ...
Background and Aim: Cytokines are believed to play an important role in the regulation of cellular immune response in hepatitis B virus infection. Interleukin 10 is a member of cytokine family. The overall expression of these molecules is mainly controlled by single nucleotide polymorphisms at specific sites on the promoter region of the Interleukin 10 gene. The aim of this study was to a...
Background and purpose: Infection caused by hepatitis B virus is a major health problem and the most common known chronic infection. It has an important role in developing cirrhosis and hepatic cancer. Glutathione-s-transferase enzyme is one of the most important metabolic enzymes in cellular protection mechanisms such as: xenobiotic detoxification and metabolism and cells protection again...

Several reasons, including presence of as...
Background and Aims: The hepatitis C virus (HCV) F protein is a recently described, frameshift product of HCV core encoding sequence. Its function and antigenic properties are unknown. In order to assess the presence of antibodies specific for F protein we characterized specific anti-F antibodies in patients with chronic HCV infection. Methods: The F protein was cloned from the HCV genome....
