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 ...
Radioimmunnoassay was used to determine the serologic subspecificities of 85 blood donor serums positive for hepatitis B virus-associated antigen. There was complete agreement with results obtained by immunoprecipitatiotn of 43 serums. The remaining 42 serums were negative by immunoprecipitation but followed type-specific immunology by radioimmunoassay, and this served as a validation for authentic hepatitis B virus antigen. ...

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 ...
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.

TY - JOUR. T1 - Hepatitis B Virus. T2 - Inappropriate Reactions to Transmission Risks. AU - Kiernan, Thomas W.. AU - Powers, Robert J.. PY - 1979/2/9. Y1 - 1979/2/9. 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 ...

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.
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.

  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.

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 ...
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.. ...

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 ...

Chronic hepatitis was diagnosed on liver biopsy of 76 patients; 52 (68%)had HBsAg. Of the 52 patients with HBsAg, 23% had HBsAg shown by immunofluorescence on the liver, while it could not be detected with radioimmunoassay on the serum; 77% had HBsAg detectable in liver and in serum, and none had HBsAg in serum only. HBsAg was detected more frequently in chronic aggressive hepatitis and active cirrhosis than in chronic persistent hepatitis and cirrhosis with little activity. No correlation was found in the different forms of chronic hepatitis between the HBsAg status on the one hand, and levels of transaminases, gammaglobulins, and auto-antibodies on the other. Acute hepatitis was diagnosed on liver biopsy of 24 patients; 50% had HBsAg. Liver tissue positivity was very low in the fully developed stage compared to serum positivity. In 146 patients with other liver ailments, both liver and serum were negative for HBsAg.. ...
