Hepatitis B Antigens
Hepatitis B virus
The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
Hepatitis B Surface Antigens
Hepatitis B Antibodies
Antibodies to the HEPATITIS B ANTIGENS, including antibodies to the surface (Australia) and core of the Dane particle and those to the "e" antigens.
INFLAMMATION of the LIVER.
Hepatitis B, Chronic
A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
Hepatitis B Vaccines
Hepatitis B Core Antigens
Hepatitis B e Antigens
INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
Sensitive tests to measure certain antigens, antibodies, or viruses, using their ability to agglutinate certain erythrocytes. (From Stedman, 26th ed)
Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
Complement Fixation Tests
Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

Hepatitis C, Chronic
Pathological processes of the LIVER.
ABO Blood-Group System
The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.

Hepatitis, Viral, Animal
INFLAMMATION of the LIVER in animals due to viral infection.
INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
Blood Group Antigens
Sets of cell surface antigens located on BLOOD CELLS. They are usually membrane GLYCOPROTEINS or GLYCOLIPIDS that are antigenically distinguished by their carbohydrate moieties.
Any of the viruses that cause inflammation of the liver. They include both DNA and RNA viruses as well viruses from humans and animals.
Viral Hepatitis Vaccines
Any vaccine raised against any virus or viral derivative that causes hepatitis.
Hepatitis Delta Virus
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
Hepatitis A Antibodies
Antibodies to the HEPATITIS A ANTIGENS including antibodies to envelope, core, and non-structural proteins.
Hepatitis E virus
A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

Antigens produced by various strains of HEPATITIS D VIRUS.
One of the type I interferons produced by peripheral blood leukocytes or lymphoblastoid cells. In addition to antiviral activity, it activates NATURAL KILLER CELLS and B-LYMPHOCYTES, and down-regulates VASCULAR ENDOTHELIAL GROWTH FACTOR expression through PI-3 KINASE and MAPK KINASES signaling pathways.
Hepatitis C Antigens
Polymorphic class I human histocompatibility (HLA) surface antigens present on almost all nucleated cells. At least 20 antigens have been identified which are encoded by the A locus of multiple alleles on chromosome 6. They serve as targets for T-cell cytolytic responses and are involved with acceptance or rejection of tissue/organ grafts.

Murine hepatitis virus
Hepatitis A Antigens
Antigens, Polyomavirus Transforming
Polyomavirus antigens which cause infection and cellular transformation. The large T antigen is necessary for the initiation of viral DNA synthesis, repression of transcription of the early region and is responsible in conjunction with the middle T antigen for the transformation of primary cells. Small T antigen is necessary for the completion of the productive infection cycle.
Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.

Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

Hepatitis virus infection in haemodialysis patients from Moldavia. (2/499)BACKGROUND: Although the epidemiology of hepatitis B (HBV) and C (HCV) now seems well established for Western European countries, in Central and Eastern Europe < 50% of all dialysis centres routinely test for hepatitis C antibodies since testing is not available or is not applied to all patients. This study describes the prevalence, risk factors and clinical significance of HBV and HCV infection for the haemodialysis population of the North Eastern region of Romania, Moldavia. METHODS: The presence of HBV antigens was determined with an ELISA kit (Wellcome, Abbot) and HCV antibodies with the ELISA-3 Ortho-HCV, third generation test. The following individual data were collected: gender, age, duration of dialysis, rural/urban domicile, actual and previous HBV status, actual HCV status, known acute, clinically evident hepatitis episodes in the last 3 years, monthly alanine aminotransferase (ALAT) and aspartate aminotransferase (ASAT) levels, complete biochemical hepatic assessment at the time of the study, transfusions for the past 3 years and family history. RESULTS: HBV and HCV prevalences were 17% (stable over the last 3 years) and 75%, respectively; co-infection was seen in 10% of the subjects. Hospitalization (nosocomial infection) for HBV, blood transfusions and duration on dialysis for HCV, emerged as the main risk factors for hepatitis infection. Socio-economic conditions appear to be equally important for HCV infection, since the prevalence was significantly higher among patients from rural, underdeveloped areas than urban areas (80.8 vs 60.3%), and infection was already present in a large proportion of patients (47%) before starting dialysis, without being related to previous disease duration or blood transfusions. HBV and/or HCV was not associated with a worse clinical or biochemical profile at the time of the study. However, infected patients had significantly more previous cytolytic episodes, with higher, transient increases in ALAT and ASAT levels. CONCLUSIONS: HCV infection is endemic among dialysis centres in Moldavia. Apart from previously well-known risk factors for hepatitis infection, our study demonstrates the negative impact of socio-economic underdevelopment. Simple measures such as enforced general asepsia rules, careful disinfection and equipment sterilization, routine testing of patients from economically disadvantaged areas and monthly, serial determination of hepatic enzymes should be the common practice in dialysis centres in Romania.

Human hepatitis B virus X protein is detectable in nuclei of transfected cells, and is active for transactivation. (3/499)Subcellular localization and transactivation of human hepatitis B virus X protein (HBx), a plausible causative factor for hepatocellular carcinogenesis, were studied in transiently transfected cells. The transactivation was detected not only by the cis-element driven chloramphenicol acetyltransferase (CAT) assay but also by immunostaining of CAT protein cotransfected into human hepatoma cell line HepG2. Scanning fluorescence microscopy showed the majority of immunological signals of HBx to be at the perinuclear region of transfected cytoplasm. HBx was also clearly detectable in the nucleus, though less intensely expressed. This was confirmed by Western analysis and coimmunoprecipitation of HBx with transcription factor IIB (TFIIB) in subcellular fractionations. The percentage of HBx-positive cells coincided with that of CAT-positive cells, and confocal laser microscopy revealed the coexistence of CAT signals in GFP-HBx positive cells. The SV40 large T antigen nuclear localization signal (NLS) appended HBx, regardless of whether NLS was added to the N- or C-terminus, transactivated all the examined X-responsive elements (XRE) similarly as did wild-type HBx. Similar results were obtained in p53 negative Saos-2 cells. The detected nuclear HBx may be involved in modulating the transcription at the promoter level whereas the HBx in cytoplasm may be working through signal transduction pathways. (+info)
HBV-specific immune defect in chronic hepatitis B (CHB) is correlated with a dysregulation of pro- and anti-inflammatory cytokines. (4/499)The aim of this study was to examine the immunomodulating effects of rhIL-12 on the immune response induced by hepatitis B virus (HBV) antigens in clinical subgroups of patients with HBV infection. Peripheral blood mononuclear cells (PBMC) of 80 patients were stimulated with HBsAg, HBcAg, pre-S1Ag and tetanus toxoid in the absence or presence of IL-12 (0.01, 0.1 and 1 ng/ml). Stimulation by anti-CD3+ anti-CD28 and lipopolysaccharide (LPS) were used as controls. Proliferation and cytokine production were determined by 3H-thymidine uptake and ELISA after 72 h. After stimulation with HBV antigens only, production of tumour necrosis factor-alpha (TNF-alpha) or IL-10 was observed in all patients, while interferon-gamma (IFN-gamma) was detectable in only 27 patients. After costimulation with IL-12 and HBV antigens, however, large amounts of IFN-gamma were found in all patients, while HBV-induced IL-10 production remained mostly unchanged. When clinical subgroups including patients with compensated liver cirrhosis were compared, PBMC from patients with HBeAg+ hepatitis showed the lowest capacity to produce IFN-gamma after HBV antigen-positive IL-12. These data suggest that the ability of IL-12 to enhance IFN-gamma production against HBV antigens is correlated with the presence of HBeAg and is not impaired in patients with advanced liver disease. In addition, IL-12 and IL-10 production by antigen-presenting cells may be a critical factor that determines the efficacy of the immune response against the hepatitis B virus. (+info)
The hepatitis B pX protein promotes dimerization and DNA binding of cellular basic region/leucine zipper proteins by targeting the conserved basic region. (5/499)The hepatitis B virus pX protein is a potent transcriptional activator of viral and cellular genes whose mechanism of action is poorly understood. Here we show that pX dramatically stimulates in vitro DNA binding of a variety of cellular proteins that contain basic region/leucine zipper (bZIP) DNA binding domains. The basis for increased DNA binding is a direct interaction between pX and the conserved bZIP basic region, which promotes bZIP dimerization and the increased concentration of the bZIP homodimer then drives the DNA binding reaction. Unexpectedly, we found that the DNA binding specificity of various pX-bZIP complexes differs from one another and from that of the bZIP itself. Thus, through recognition of the conserved basic region, pX promotes dimerization, increases DNA binding, and alters DNA recognition. These properties of pX are remarkably similar to those of the human T-cell lymphotrophic virus type I Tax protein. Although Tax and pX are not homologous, we show that the regions of the two proteins that stimulate bZIP binding contain apparent metal binding sites. Finally, consistent with this in vitro activity, we provide evidence that both Tax and pX activate transcription in vivo, at least in part, by facilitating occupancy of bZIPs on target promoters.

HBV and proteinuria in relatives and contacts of children with hepatitis B virus-associated membranous nephropathy. (6/499)BACKGROUND: Hepatitis B virus (HBV)-associated membranous nephropathy (HBVMN) is an important cause of childhood nephrotic syndrome in regions endemic for the virus, but little is understood of the biosocial context in which the disease develops. We evaluated HBV status and proteinuria in family members and household contacts of index children with HBVMN to test the hypothesis that HBV carriage and asymptomatic proteinuria are closely linked and may be causally associated. METHODS: Thirty-one black children with biopsy-proven HBVMN were the index cases. One hundred and fifty-two family members and 43 black household contacts were the subjects of the study. We assessed HBV carrier status by testing for HBV antigens and antibodies using enzyme-linked immunosorbent assays (ELISA) and for HBV DNA by using slot-blot hybridization and the polymerase chain reaction. Sequencing of the precore region of HBV was done in a subset of both index cases and subjects. Proteinuria was assessed by measuring the urinary protein/creatinine ratio. RESULTS: Seventy-two (37%) of the 195 family members and household contacts were HBV carriers, and 53 (27%) had a protein/creatinine ratio greater than the physiological limit. The frequency of abnormal proteinuria was not significantly different in those with [22 out of 72 (30.5%)] or without [33 out of 104 (32%)] HBV carriage. This lack of association remained when carriers were classified into those who were HBsAg positive only and those with active viral replication (HBsAg and/or HBeAg and/or HBV DNA; P = 0.01). Family members were more predisposed to HBV carriage than household contacts, but abnormal proteinuria was present with equal frequency (P = 0.48). Age had a significant impact on proteinuria, with children less than five years being more likely to have abnormal proteinuria (P = 0.008). The prevalence of abnormal proteinuria in family members and household contacts of the index cases was more than that in community-based controls. The 10 index HBVMN cases and the 14 family members and household contacts who were tested all had HBV of genotype A. CONCLUSION: These results suggest that the family members and household contacts of children with HBVMN are at very high risk of HBV carriage; they also have asymptomatic proteinuria at a significantly higher rate than community-based controls. The HBV carrier status was not associated with proteinuria, a finding supported by peak prevalences of proteinuria in those under five years but no corresponding peak for HBV carriage. Proteinuria may indicate glomerular basement membrane dysfunction. Environmental and social factors may underpin development of these two covert disorders, but are insufficient to account for the index cases of HBVMN. The emergence of children with HBVMN from such households additionally depends on unidentified and possibly genetic factors. (+info)
The proapoptotic effect of hepatitis B virus HBx protein correlates with its transactivation activity in stably transfected cell lines. (7/499)The role of hepatitis B virus HBx protein in the carcinogenesis associated with chronic viral infection remains ill-defined. Indeed, pleiotropic effects have been ascribed to HBx: in addition to its well-documented ability to indirectly stimulate transcription, the protein has been reported to affect cell growth, signal transduction, DNA repair and apoptosis. In this work, we generated Chang (CCL-13)-derived cell lines constitutively expressing wild type or mutant HBx, as a model of HBx-host cell interaction closer to the chronic infection setting, than the classically used transient expression systems. We document the potentiation by HBx of the apoptotic cell death pathway in the recipient cells. This effect is unlikely to rely on p53 activity since the protein is functionally inactivated in CCL-13. In addition, antioxidants and cyclosporin A failed to reduce the apoptotic response back to the normal level, suggesting that production of reactive oxygen species and calcineurin activation are not directly involved in the proapoptotic effect of HBx. In contrast, our data show that transactivation and stimulation of apoptosis are tightly linked HBx activities. Finally, expression of transactivation-active protein did not result in detectable change in the pattern of MAP kinases phosphorylation nor did it affect the ability of the host cell to repair in vitro irradiated plasmid DNA.

Genetic alterations in hepatocellular carcinomas: association between loss of chromosome 4q and p53 gene mutations. (8/499)The major risk factors for hepatocellular carcinomas (HCC) in high incidence areas include infection with hepatitis B and C viruses (HBV, HCV) and exposure to aflatoxin. Genetic alterations in 24 liver resection specimens from Shanghai and Qidong were studied. Hepatitis B virus was integrated in all patient samples, and a null phenotype for the GSTM1 enzyme was present in 63% of patients. Alteration of p53 was present in 95% (23/24) of cases: mutations of the p53 gene in 12 HCC, p53 overexpression in 13 and loss of heterozygosity (LOH) of chromosome 17p in 17. All seven HCCs with a p53 mutation from Qidong and three of five from Shanghai had the aflatoxin-associated point mutation with a G to T transversion at codon 249, position 3. No HCC had microsatellite instability. LOH of chromosome 4q, 1p, 16q and 13q was present in 50%, 46%, 42% and 38%, respectively, and 4q was preferentially lost in HCCs containing a p53 mutation: LOH of 4q was present in 75% (9/12) of HCC with, but only 25% (3/12) of HCC without, a p53 gene mutation (P = 0.01). These data indicate a possible interaction between p53 gene mutation and 4q loss in the pathogenesis of HCC. (+info)
Subtypes of Hepatitis B Antigen: Clinical Relevance? | Annals of Internal Medicine | American College of Physicians
The synthesis of Australia or hepatitis B antigen (HB Ag) is now considered to be the characteristic hallmark of infection by hepatitis B virus (HBV) and is therefore one of the most important criteria in the diagnosis of type B hepatitis. Hepatitis-B antigenic reactivity is associated with the surface of the spherical and tubular particles (20 nm in diameter) found in the serum of patients and carriers. The outer coat of the relatively rare 42-nm Dane particles also exhibits this HB-Ag reactivity, but their inner component or core is antigenically distinct. At the moment, the most credible claimants to the ...

Comparative evaluation of methods for research on Australia antigen]. - Semantic Scholar
490 blood samples have been examined for the comparison of the various methods concerned with the detection of the Australia Antigen (Au). The following methods have been comparatively examined: immunodiffusion (ID) counterelectrophoresis (CEP), complement fixation (CF) passive hemoagglutination (HA) and solid phase radioimmunoassay RIA. On the basis of the results so far obtained the RIA appears the most sensitive and specific method, followed by the HA. In order to obtain reproducible results for diagnostic purposes we suggest to carry out routinely two different techniques together (possibly RIA and HA), while for screening purposes just one technique, choosed between the two most indicative ones, shall be employed.

Vaccination by Banana New Scientist 96. BANANAS, genetically engineered to carry vaccines, could provide developing countries with a cheap way to protect children from life-threatening diseases, according to researchers in the US. Biotechnologists at the Boyce Thompson Institute for Plant Research an independent research centre at Cornell University in New York State, are genetically engineering a banana to produce an antigen found in the outer coat of the hepatitis B virus. Banana vaccines would be ideal for developing countries because they would cost just a few cents per dose, compared 10 the $100 to $200 per dose for traditional vaccines, says Charles Arntzen, president of the institute.. Last year, the team showed that hepatitis B antigens produced by genetically engineered potatoes triggered an immune response in rats. But because potatoes are not eaten raw, and cooking them would destroy the vaccine, tiley are unsuitable for vaccinating people. So the researchers switched their efforts to ...
Isolation and purification of a non-A, non-B hepatitis-associated microtubular aggregates protein | Microbiology Society
Blood-borne type non-A, non-B (NANB) hepatitis-associated microtubular aggregates protein was isolated and partially sequenced. The microtubular aggregates were isolated from the hepatocytes of NANB-infected chimpanzees and were found to have a buoyant density in sucrose solution of 1.21 to 1.23 g/ml. A single protein, recognized by our anti-microtubular aggregates monoclonal antibodies, was found to have an M r of 44000 (p44). This p44 protein was not found in uninfected chimpanzees. We determined a partial amino acid sequence for p44, and showed that it has no homology to any known proteins.

Dane: Supercars parity battle almost destroyed the sport - Speedcafe
Last years Supercars parity saga nearly ruined the sport according to Triple Eight Race Engineering owner Roland Dane.. Speaking on the latest episode of Rustys Garage, Dane detailed his first glimpse of the then-new Ford Mustang that debuted at the VCAT test in late 2018.. He said Supercars was presented with a situation unprecedented in his time in the championship.. The other side turned up with a car that was just so radically different from anything that had been done before, we knew we were on the back foot, Dane told host Greg Rust.. But because Supercars as a category had never been placed in this position - or certainly in the 16 years that I had been around - then they didnt really know how to deal with it, which is totally different to how the landscape had been for the Ford versus Holden fight all the time I had been in Australia.. I would never say there havent been differences, but they were so small that other things had been more important. The team, the driver, etc. It ...

N2 - Ten patients designated as hepatitis B surface antigen (HBAg) carriers were screened for inappropriate reactions to their disease. Assessment with a 32-item questionnaire showed three carriers to have underreacted to the risks of HBAg transmission through misunderstandings or denial concerning the disease. One carrier, through severe social withdrawal, showed overreaction to the possibilities of disease transmission. Counseling was provided regarding the risks of HBAg transmission. At a one-month followup, all carriers appeared appropriately aware of the risks of transmission, and one of two carriers referred for psychotherapy showed greatly improved social adjustment. We recommend that persons treating HBAg carriers screen routinely for inappropriate reactions to risks of disease transmission and provide counseling as ...

The American Journal of Tropical Medicine and Hygiene | Hepatitis-Associated (Australia) Antigen in Nigerians
Abstract A series of Australia antigen-positive sera from healthy Nigerians was examined using the electron microscope. One serum was outstanding inasmuch as it contained a vast preponderance of the large 420 A Dane particles. Other sera exhibited the appearance accepted as the usual one in Australia antigen-positive sera. The significance of this variation in proportion of antigen forms is discussed and it is suggested that variations of this type could be of importance in prognosis.
Ground glass hepatocyte - Wikipedia
In liver pathology, a ground glass hepatocyte, abbreviated GGH, is a liver parenchymal cell with a flat hazy and uniformly dull appearing cytoplasm on light microscopy. The cytoplasms granular homogeneous eosinophilic staining is caused by the presence of HBsAg. The appearance is classically associated with abundant hepatitis B antigen in the endoplasmic reticulum, but may also be drug-induced. In the context of hepatitis B, GGHs are only seen in chronic infections, i.e. they are not seen in acute hepatitis B. GGHs were first described by Hadziyannis et al. Several different types of GGHs are recognized: Type I - morphologically consist of GGHs that are scattered singly and have weak Pre-S2 positive immunostaining. Type II - morphologically consist of GGHs that are in clusters and have Pre-S2 negative immunostaining. There is some evidence to suggest that type II GGHs predispose to hepatocellular carcinoma.

Australia antigen is the covering or capsule of HBV. Many a times an organism is identified on the basis of its covering thus similarly the presence of HBV in the body is often determined by its outside covering. It was first discovered in an Australian Tribal Man thus the name. Australia antigen is also called as â€œHepatitis â€B Surface Antigenâ€ (HBsAg).. ...
Ilmuwan Temukan Mumi Hepatitis-B Tertua
Detikone.com, JAKARTA -- Mumi anak yang dikubur di Basilika Saint Domenico Maggiore, Naples, Italia pada 1980-an atau abad ke-16 sejauh ini dikenal sebagai kasus cacar paling awal yang ditemukan di dunia. Masalahnya, anak berusia dua tahun itu belakangan diketahui tidak terkena cacar air, menurut penelitian terbaru yang diterbitkan IFL Science. Ilmuwan kembali memeriksa sisa-sisa penemuan kuno yang masih merupakan studi penting dalam evolusi penyakit. Mumi anak tersebut tampaknya terkena hepatitis-B. Penemuan ini memberikan wawasan baru bagi peneliti tentang bagaimana virus tersebut berevolusi selama beberapa abad terakhir. Virus hepatitis-B atau HBV menyerang hati dan menyebabkan sirosis juga kanker hati. Virus ini menewaskan sekitar 887 ribu orang per tahun. Meski saat ini sebagian besar kasusnya bisa dicegah lewat vaksin, Organisasi Kesehatan Dunia (WHO) memperkirakan sekitar 257 juta orang di seluruh dunia hidup dengan HBV. Virus ini menyerang anak-anak,

Interruption of Maternal-to-Infant Transmission of Hepatitis B by Means of Hepatitis B Immune Globulin - Full Text View -...
BACKGROUND:. A baseline study on the vertical transmission of hepatitis B virus in Taiwan revealed that 15 percent of all pregnant women were persistent carriers of hepatitis B antigen and that 40 percent of their new babies developed a protracted antigenemia during the first 6 months of life. The incidence of acute hepatitis, cirrhosis, and hepatoma was high in Taiwan, and patients with these disorders had a fivefold to sixfold higher prevalence of hepatitis B antigen than healthy persons. Given the important public health problems of this disease in Taiwan and the rest of the Third World, this trial sought to answer the important question of whether hepatitis B immune globulin with a high level of antibody against the antigen would be of utility in combating the problem.. Two hundred and five babies were accepted into the study, which was actually conducted on Taiwan through a contract to the Community Blood Council of Greater New York. Only those babies born of mothers who had HBsAg ...
The Australia (hepatitis-associated) antigen in fibrinogen and other fractions of human plasma | Journal of Clinical Pathology
Human plasma containing the Australia (hepatitis-associated) antigen was fractionated by the cold ethanol method of Cohn, Strong, Hughes, Mulford, Ashworth, Melin, and Taylor (1946) and small aliquots were examined for the presence of this antigen by immunodiffusion and by electron microscopy. The findings were in general agreement with the postulated risk of transmitting hepatitis by blood derivatives. The Australia (hepatitis-associated) antigen was detected in fibrinogen, thrombin, and antihaemophilic globulin as well as in other fractions. The antigen was not found in gamma globulin (immunoglobulin fraction) nor in albumin.. The use of radioiodinated fibrinogen for the diagnosis of deep vein thrombosis is discussed and it is concluded that the use of fibrinogen for diagnostic procedures should be assessed against the possible risk of hepatitis.. ...

IMI Karachi Hepatitis-B Vaccination Camps
Hepatitis-B is reported with high incidence in Pakistan because of lack of awareness, causing morbidity and mortality among patients. This disease can be prevented through vaccination. Unfortunately, a large number of people cannot afford vaccination due to its cost.. In order to help those needy people, IMI Pakistans Karachi Chapter organized free vaccination camps at different areas. Like previous year, IMI Karachi teams, under the supervision of Dr. Hani and with support of other paramedical staff, set up a number of camps in different areas including Muhabat Nagar, Incholi, Jogi Mor Malir, Ammar-e-Yasir Society, Ayoub Goth, Paradise Medical & Emergency Centre and Gulshan-e-Hadeed. 1800 people throughout Karachi were vaccinated during these camps ...

Blood type Facts for Kids
The principle of the ABO system is that antigens - in this instance, sugars exposed on the surface of red blood cells - differ between individuals. People have immunological tolerance only for what occurs in their own bodies. As a result, humans may produce antibodies against natural components in the bodies of other people, but not themselves. So, people may produce antibodies against A and/or B antigens if they are not in their blood.. These antibodies clump red blood cells together if they carry the foreign antigens. This harsh response can cause death when large amounts of such cells are encountered after a blood transfusion. Because A and B antigens are chemically modified from a precursor form that is also present in type O individuals, people with type A and B antigens can accept blood from type O individuals.. Anti-A and anti-B antibodies are not present in the newborn. They appear in the first years of life. Anti-A and anti-B antibodies are usually too big to pass through the placenta ...
