Hepatic effects of repeated halothane anesthetics in the hypoxic rat model.

abstract：BACKGROUND:Propofol is an intravenous anesthetic agent that may impair host defense system. The aim of this study was to evaluate the effects of propofol on macrophage functions and its possible mechanism. METHODS:Mouse macrophage-like Raw 264.7 cells were exposed to propofol, at 3, 30 (a clinically relevant concentra...
