Toshiya Ochiai, Yoji Urata, Takeshi Yamano, Hisakazu Yamagishi, Tsukasa Ashihara – 30 December 2003 – Clonal analysis has shown that hepatocellular carcinoma arises from a single cell. However, the clonality of precancerous lesions and adjacent nonneoplastic tissues is not clear. We analyzed a human androgen receptor locus to elucidate the clonal state of liver tissues including post‐hepatitic lesions associated with hepatocarcinogenesis.

Elferink – 30 December 2003 – We have studied regulation of the multidrug resistance protein 2 (mrp2) during bile duct ligation (BDL) in the rat. In hepatocytes isolated after 16, 48, and 72 hours of BDL, mrp2‐mediated dinitrophenyl‐glutathione (DNP‐GS) transport was decreased to 65%, 33%, and 33% of control values, respectively.

Henry L. Y. Chan, Nancy W. Y. Leung, Munira Hussain, May L. Wong, Anna S. F. Lok – 30 December 2003 – Hepatitis B e antigen–negative chronic hepatitis B (e−CHB) has been reported in Asia but its prevalence and clinical significance have not been determined. The aims of this study were to determine the prevalence of e−CHB in Hong Kong and the frequency of precore and core promoter mutations in these patients. A cross‐sectional study was performed in 350 consecutive Chinese patients (230 men and 120 women; mean age ±SD, 42 ± 13 years) with chronic hepatitis B virus infection.
