Anti-Inflammatory Effects of Aurantiochytrium limacinum 4W-1b Ethanol Extract on Murine Macrophage RAW264 Cells

Figure 2

Comparison of reduction in nitrite oxide production in mouse RAW 264 cells pretreated with ethanol extracts of AL4W-1b and AM18W-13a. RAW264 cells were pretreated with ethanol extracts of AL4W-1b and AM18W-13a at concentrations of 1/5000 and 1/1000 for 24 h. After pretreatment, the cells were activated with LPS (1 ng/mL) for 12 h. NO production was measured by Griess reaction. Values are expressed as the mean ± SD of triplicate experiments and are expressed as a percentage of the control LPS (+) treatment. The asterisk indicates a mean value that is significantly different from that of the control group ( p < 0.01).
