Impact of hepatic rearterialization on reperfusion injury and outcome after mouse liver transplantation.

Background: Nonarterialized mouse liver transplantation is a well-established model for immunologic studies on rejection and tolerance mechanisms. However, the importance of graft arterialization has-in contrast to rat liver transplantation-not been thoroughly examined in the mouse model. The aim of the current study was to investigate the impact of arterial reconstruction on long-term graft survival, histologic alterations, ischemic liver damage, and early immunologic activation pathways.

Intraoperative management of cystic meningiomas.

Cystic meningiomas are uncommon tumors that are easily confused with metastatic or glial tumors with cystic components. We report on our experience of intraoperative findings and management of peritumoral cyst wall and cyst fluid in cystic meningiomas. We reviewed all the meningiomas operated on at our department in a 3 1/2-year period (January 1998 to June 2001).
