Carlo H. Tamburro, Laszlo Mark, Hans Popper – 1 May 1984 – Focal hepatocellular hyperplasia and focal mixed (hepatocytes and sinusoidal cells) hyperplasia are early histological alterations indicative of vinyl monomer exposure. To evaluate their uses in screening chemical workers, 93 liver biopsy specimens from 78 persons were examined in double‐blind duplicative fashion. Forty‐eight specimens were from exposed chemical workers, 35 of them having liver biopsy(ies) for hepatic test abnormalities and 13 for nonliver‐related reasons.

Masahiro Asaka, Tamotsu Miyazaki, F. Blaine Hollinger, Elliot Alpert – 1 May 1984 – A solid‐phase, noncompetitive radioimmunoassay has been developed for aldolase B in human serum and tissues. Aldolase B was purified from human liver, and specific antisera to purified aldolase B were obtained from chickens. Specific antihuman aldolase B IgG was purified by affinity chromatography. Disposable polypropylene plates were coated with affinity purified specific IgG antibody and used for radioimmunoassay with 125I‐specific IgG antibody to aldolase B.

D. Paul Cleland, T. Carl Bartholomew, Barbara H. Billing – 1 May 1984 – The effect of bile duct ligation for 5 days on the hepatic transport of sulfated and nonsulfated bile acids was studied. Tracer doses of radioactive bile acids [3H]taurochenodeoxycholate‐3‐sulfate [3H]chenodeoxycholate‐3‐sulfate, [3H]taurochenodeoxycholic acid and [14C]taurocholic acid were injected 90 min after relief of obstruction when the plasma total bile acid concentration had reverted to normal.

Kwesi N. Tsiquaye, Tim J. Harrison, Bernard Portmann, Shanlian Hu, Arie J. Zuckerman – 1 May 1984 – Two hepatitis B virus carrier chimpanzees which were superinfected with hepatitis A virus developed acute hepatitis followed by the production of antibodies to hepatitis A virus. The Southern blot technique employed to monitor liver hepatitis B virus DNA revealed that the amount of viral DNA in both animals was significantly reduced during the acute phase of hepatitis A infection. The levels of plasma hepatitis B DNA polymerase activity were also reduced in one chimpanzee.

Marisabel Mourelle, Marcos Rojkind – 1 May 1984 – When compared to normal liver membranes, purified plasma membranes of regenerating liver and Morris hepatomas contain low but variable capacities to bind glucagon. This property is inversely related to the capacity of the isolated hepatocytes to bind to heterologous biomatrix glycoproteins. Since these parameters are characteristic of the proliferative state of the cells, it was important to further study the glucagon receptor protein and stimulation of adenylate cyclase activity.
