Studies on pre-S2 antigen and antibody in various HBV infection.

STUDIES ON CYTOMEGALOVIRUS INFECTION AND ANTINUCLEAR ANTIBODY AMONG VITILIGO PATIENTS IN AHWAZ IRAN

Recently, using polymerase chain reaction (PCR) technique, the DNA of cytomegalovirus was detected from depigmented white patches in patients with vitiligo. The reactivation of infection and occasional anti-CMV IgM circulating among patients infected by cytomegalovirus has been reported for years. We have studied 26 patients with clinical signs and symptoms of vitiligo, some of whom had a ...

Studies on Antigen-antibody Complexes

Solid phase immunoadsorbents were prepared by coupling antigens to agarose. With this technique specific antibodies were easily isolated in large amounts. The gammaG-globulin class of antibodies isolated in this manner were not denatured as judged by their normal biological half-life in rabbits. Soluble immune complexes at fivefold antigen excess were prepared from isolated specific antibodies ...

Indication of Anti-HBc Antibody Screening and HBV-DNA Detection in Diagnosing Latent Hepatitis B Virus Infection

Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...

Therapeutic Direction and Issues Regarding HBV Infection

With up to 400 million affected people worldwide, chronic hepatitis B virus (HBV) infection is still a major health care problem. During the last decade, several novel therapeutic approaches have been developed and evaluated. In most regions of the world, interferon-α (IFN-α), and nucleos(t)ide analogues are currently approved. Despite major improvements, none of the existing therapies is optim...
