Table 2. Concentration- and Time-dependent Effects of Propofol on Phagocytotic Activities of Macrophages

Values shown as mean ± SD for n = 6. Macrophages were treated with 3, 30, and 300 μm propofol for 1, 6, and 24 h. Phagocytotic activities were determined by counting the fractions of macrophages that digested at least one fluorescent particle.

*P < 0.05; statistically different from the respective control.
