Kazuhiko Hosoda, Masao Omata, Katsuo Uchiumi, Fumio Imazeki, Osamu Yokosuka, Yoshimi Ito, Kunio Okuda, Masao Ohto – 1 January 1990 – Replication of duck hepatitis B virus in extrahepatic tissue such as pancreas, kidney and spleen has been well documented. To assess whether there is more widespread extraheptic virus replication, we assayed brain, heart, lung, thymus, pancreas, kidney, spleen and intestine of 1‐ to‐wk‐old ducklings for the presence of duck hepatitis B virus DNA and mRNA by blotting in in situ methods.

Pitambar Somani, Subhankar Bandyopadhyay, James E. Klaunig, Susan A. Gross – 1 January 1990 – Hepatocytes isolated from Sprague‐Dawley rats were incubated with various concentrations of either amiodarone or desethylamiodarone fro 0 to 69 hr. Both drugs produced a concentration‐dependent increase of lactate dehydrogenase release in the culture medium, which correlated well with cell death as measured by trypan blue exclusion test. Desethylamiodarone was more toxic than amiodarone in the cultured hepatocytes.

Karel J. Van Erpecum, Gerard P. Berge Van Henegouwen, Bregt Stoelwinder, Yvonne M. G. Schmidt, Frans L. H. Willekens – 1 January 1990 – We investigated whether bile concentration influenced cholesterol saturation index or nucleation time of cholesterol monohydrate crystals in a large number of gallbladder bile samples. Pigment stone patients never had cholesterol crystals in their fresh biles, and nucleation time was always longer than 20 days. Of the cholesterol stone patients 79% had cholesterol crystals in their fresh biles.
