NO content of RG, CG150, CG350, and CG750. NO assay using the cells treated with LPS (1 μg/ml) in the absence or presence of RG, CG150, CG350, and CG750 at different concentrations (100, 250, and 500 mg/ml, respectively) for 24 h ( < 0.01 vs. LPS; ^♦♦ < 0.01 vs. CG150 (100 mg/mL) and CG350 (100 mg/mL); ^★★ < 0.01 vs. CG150 (250 mg/mL) and CG350 (250 mg/mL); ^&& < 0.01 vs. CG150 (500 mg/mL) and CG350 (500 mg/mL)).
