We evaluated the usefulness of synthetic absorbable sutures (Vicryl) in preventing surgical site infection (SSI) after hepatectomy. A rat model of 60% partial hepatectomy was used. Bleeding from the cut surface of the liver was controlled by using two suture types: silk and Vicryl. In the Vicryl group, the lesser omentum was slightly adherent to the cut(More)
Prostaglandin E1 (PGE1) has wide-ranging effects on cytoprotection and may play a role in preventing liver failure following excessive hepatectomy. We examined the effect of PGE1 on hepatocyte apoptosis and liver regeneration after 95% hepatectomy in a rat model. PGE1 or vehicle was intravenously administered 30 minutes before and during hepatectomy. The(More)
BACKGROUND/AIMS Well-organized turnover of the extracellular matrix is important in liver regeneration, which is regulated by the plasminogen activating system. The aim of this study was to investigate the role of plasminogen activator inhibitor-1 (PAI-1) after excessive hepatectomy and to ascertain whether angiotensin-converting enzyme (ACE) inhibitors,(More)
BACKGROUND Macrophages play an important role in the initiation of hypercytokinemia, which is involved in the development of liver failure after excessive hepatectomy. This study was aimed at evaluating whether the selective suppression of nuclear factor kappa B (NF-kappaB) in macrophages by decoy oligodeoxynucleotides (ODN) could prevent liver failure(More)
BACKGROUND/AIM Prostaglandin E1 (PGE1) has a wide-ranging effect on cytoprotection. Overproduction of heat shock protein 70 (HSP70) in the liver protects hepatocytes under various pathologic conditions. In this study, we examined the effect of a nontoxic HSP-inducer, PGE1, on acute liver failure after 95% hepatectomy in rats. METHODS PGE1 or vehicle was(More)
BACKGROUND/AIMS Nitric oxide synthase 2 (NOS2) is expressed during liver regeneration after a partial hepatectomy (PHx); NOS2 subsequently synthesizes nitric oxide (NO). However, the role of NOS2-synthesized NO in post-PHx liver regeneration remains unclear. We investigated the role of NOS2-synthesized NO in liver regeneration. METHODS NOS2 knockout(More)
