The changes of COX-2, PGE2 and its receptors in each group. (a) mRNA expression of COX-2 in the tonsil was determined by qRT-PCR. (b) PGE2 content in the tonsil was determined by ELISA. (c-f) mRNA expression of EP1, EP2, EP3 and EP4 in the tonsil was determined by qRT-PCR. Data were expressed as mean ± SEM. n = 20 in control group; n = 10 in TH group; n = 15 in TH + RI group. *P < 0.05 compared to the control group; **P < 0.01 compared to the control group; #P < 0.05 compared to the TH group; ##P < 0.01 compared to the TH group; ns (no significance) compared to the control group or TH group
