BACKGROUND AND OBJECTIVES Anesthesiologists are especially exposed to blood and secretions. Hepatitis B virus infection is the major occupational risk for health care professionals. This study aimed at evaluating the prevalence of Ag-HBs, anti-HBs and anti-HBc among anesthesiologists of the city of Goiânia, as well as their vaccination status. METHODS Participated in this study 90 out of 200 ...

The internal fluid flow capacity of hydrate-bearing sediment (HBS) is one the important factors affecting efficiency natural gas exploitation. This paper focuses on seepage studies hydrates with following contents: scope theories’ application, normalized permeability (Kt) models, extension combined new technology, and development. No review has elucidated prediction original (K0) sediments with...

BACKGROUND The standard treatment of stroke in sickle cell disease is chronic transfusion to maintain the fraction of abnormal hemoglobin (hemoglobin S [HbS]) below 20%. Risks associated with such transfusion can be reduced by allowing higher HbS levels, but the physiological consequences of this modification are unknown. Cerebral blood flow is elevated in sickle cell disease proportionate to t...

The significance of a delayed type hypersensitivity skin reaction to hepatitis B surface antigen (HBsAg) (HBs-DTH) in type B viral hepatitis (VHB) and in intradermal hepatitis B (HB) vaccination is reviewed. HBs-DTH could be developed by the intradermal injection of HB vaccine in anti-HBs positive people and also in persons immunized with HB vaccine. Thus, HBs-DTH could serve as a useful marker...

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 risk for transmission of blood-borne viruses (bbvs) such as human immunodeficiency virus (hiv), hepatitis b virus (hbv) and hepatitis c virus (hcv) due to occupational exposure is a major concern in the health care setting. m aterials and methods: this study among 337 health care workers (hcws) accidentally exposed to bbvs was carried out from january 2009 to march 2015. the dat...

BALB/c mice receiving antiidiotype antibodies before the injection of hepatitis B surface antigen (HBsAg) generated an enhanced anti-HBs response. Mice given antiidiotype antibodies in a soluble form induced predominantly IgM anti-HBs, whereas alum-precipitated antiidiotype produced primarily IgG anti-HBs. Injection of antiidiotype antibodies alone induced anti-HBs that inhibited a common inter...

Hepatitis B is a global serious disease caused by hepatitis B virus (HBV). There is no known cure for hepatitis B. The best way to deal with the disease is by preventing with hepatitis B vaccine. However, the current protein-based vaccines made up of recombinant hepatitis B surface antigen (HBsAg) are ineffective in chronic HBV carriers and a significant number of the vaccinees do not mount the...

OBJECTIVE To investigate the effect of immunosuppressive anticancer therapy on titre levels of anti-hepatitis B surface antibodies (anti-HBs) in hepatitis B surface antigen (HBsAg) negative and anti-HBs positive patients with haematological malignancies or solid tumours. METHODS This retrospective study reviewed the medical records of patients with haematological malignancies or solid tumours...

AIM To retrospectively analyze different methods in differentiating biliary atresia from idiopathic neonatal hepatitis. METHODS Sixty-nine infants with cholestatic jaundice and final diagnosis of idiopathic neonatal hepatitis (INH) and biliary atresia (BA) were studied retroprospectively from January 2004 to December 2006. A thorough history and physical examination were undertaken. All cases...
