Average annual age-adjusted mortality rates per 100,000 from primary hepatic carcinoma (PHC) among males for 1971-1973 in the urban and rural areas of the 9 geographical regions of Greece were estimated. Hepatitis-B surface antigen (HBsAg) prevalence by region and area was evaluated in a sample of 22,844 Greek Air Force recruits from all parts of the(More)
The localization of hepatitis B antigen (HB Ag) and the nature of the virus-like particles in hepatocytes of patients with HB antigenemia are controversial. In many reports, numerous virus-like particles have been demonstrated in hepatocytic nuclei; the few reported in the cytoplasm are insufficient in number to explain the intense cytoplasmic fluorescence(More)
The safety and immunogenicity of adw and ayw hepatitis B vaccines were compared in a double-blind randomized trial in Green Air Force recruits. One hundred and ten out of 240 eligible nonimmune recruits were randomly selected and allocated to the two vaccine treatment groups. Two 20-micrograms doses 1 month apart and a third 20-micrograms booster dose, at 6(More)
The immunogenicity of a 5-micrograms dose of vaccine (H-B-Vax, MSD) was evaluated in 50 young adults (17-19 years). Results were compared to our previous studies using similarly prepared vaccines using 20 micrograms and 10 micrograms per dose with the same trial protocol in a comparable population. Seroconversion rates for the 5-micrograms doses of vaccine(More)
The immunopotentiating effect of the intradermal administration of a course of four doses (0.25 ml) of a standard suspension of killed C. parvum (2 mg/ml) was studied in a group of 10 asymptomatic chronic hepatitis B surface antigen (HBsAg) carriers, as well as in 11 persons with antibodies to HBsAg (anti-HBs) and six without HBsAg or anti-HBs.
