Nitric oxide is an active oxidant that contributes to the physiology and pathophysiology of macrophages. Propofol has been widely used in intravenous anesthesia. It possess antioxidant and immunomodulating effects. This study aimed to evaluate the effects of propofol on nitric oxide production in lipopolysaccharide-activated macrophages. Exposure of macrophages to propofol (25, 50 and 75 μM), to lipopolysaccharide (0.5, 1, 1.5 and 2 ng/ml) or to a combination ofpropofol and lipopolysaccharide did not affect cell viability. However, propofol at 100 μM led to significant cell death (P3 versus 92±6×103 arbitrary units, P2 versus 30±4×102 arbitrary units, P
