A Cell viability. B NO secretion levels. C IL-6 content. D IL-1β content. E TNF-α content. Values are expressed as the mean ± SD (n = 3). Different lowercase letters indicate significant differences (p < 0.05). *p < 0.05, **p < 0.01, and ***p < 0.001 versus the blank group; #p < 0.05, ##p < 0.01, and ###p < 0.001 versus the LPS group.
