Data are presented as mean ± S.D. from experiments repeated 6 times. * Indicates the statistical significance of the difference among inflammation model group and blank group, HAPS-treated group, APS-treated group and ibuprofen-treated group (n = 6, * p < 0.05, ** p < 0.01 vs. inflammation model group).
