Immuno-serological Studies on Sashima Hepatitis (Infectious Hepatitis)

STUDIES ON HEPATITIS B VACCINES

HBs vaccines were prepared by three different methods: 1) Heat inactivation (Krugman, et.al 1971)2) Ammonium sulphate precipitation followed by column chromatography (Sephadex G-200) 3) PEG-6000 (polyethylene glycol) precipitation followed by column chromatography using Sephadex G-200. Their efficacy was studied in guinea pigs, and the results compared with commercial Japanese vaccine (Gr...

Studies on the Agent of Infectious Hepatitis

The successful cultivation of the virus of infectious hepatitis in chick embryo tissue culture and in the amniotic cavity of the embryonated hen's egg is supported by a comparison of the disease induced in volunteers by the cultivated virus with hepatitis without jaundice resulting from experimental infection with natural infectious hepatitis virus. Both types of viral preparations produced ill...

Clinical and experimental studies of infectious hepatitis.

Studies on the disturbance of glucuronide formation in infectious hepatitis.

The ability of the liver to form glucuronides was measured in 10 patients with infectious hepatitis. One test was done at the onset and another about four weeks later after the clinical symptoms had disappeared. N-acetyl-p-aminophenol (N.A.P.A.) or acetanilide was administered in doses ranging from 10 to 20 mg. per kg. body weight, either orally or by intravenous injection. N.A.P.A. is conjugat...

Viral hepatitis: recent experiences from serological studies in Bangladesh.

Infections due to hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV) and hepatitis E (HEV) viruses are the major causes of hepatitis and are associated with significant morbidity and mortality in developing countries like Bangladesh. The present study was carried out to determine the prevalence of HBsAg, anti-HCV antibody, anti-HAV antibody and anti-HEV antibody in patients suspected of ha...
