In situ determination by surface chemiluminescence of temporal relationships between evolving warm ischemia‐reperfusion injury in rat liver and phagocyte activation and recruitment

Juan Carlos Cutrìn, Alberto Boveris, Barbara Zingaro, Giovanna Corvetti, Giuseppe Poli – 30 December 2003 – Liver ischemia‐reperfusion is characterized by an increased oxygen‐dependent free radical chain‐reaction rate and an increased steady‐state concentration of reactive oxygen species. The aim of this study was to evaluate the in situ generation of reactive oxygen species and its relationship with phagocyte activation and recruitment in reperfused rat liver. Rat livers were subjected to 2 hours of selective lobular ischemia and reperfusion for up to 12 hours.

Novel molecular defects of the δ‐aminolevulinate dehydratase gene in a patient with inherited acute hepatic porphyria

Reiko Akagi, Ryo Shimizu, Kazumichi Furuyama, Manfred O. Doss, Shigeru Sassa – 30 December 2003 – Cloning and expression of the defective gene for δ‐aminolevulinate dehydratase (ALAD) from the second of 2 German patients with ALAD deficiency porphyria (ADP), who had been originally reported by Doss et al. in 1979, were performed. Cloning of cDNAs for the defective ALAD were performed using Epstein‐Barr virus (EBV)‐transformed lymphoblastoid cells of the proband, and nucleotide sequences of cloned cDNA were determined. Two separate mutations of ALAD cDNA were identified in each ALAD allele.

Prevalence and clinical course of chronic hepatitis C virus (HCV) infection and rate of HCV vertical transmission in a cohort of 15,250 pregnant women

Dario Conte, Mirella Fraquelli, Daniele Prati, Alice Colucci, Eliseo Minola – 30 December 2003 – The prevalence and natural course of chronic hepatitis C virus (HCV) infection was evaluated in 15,250 consecutive pregnant women. The rate of HCV vertical and perinatal transmission was also assessed. The presence of anti‐HCV was tested by means of EIA III and confirmed by recombinant immunoblot assay III.
