Table 1. In vivo antiinflammatory effects of CpdA in a zymosan-induced inflamed paw mouse model.

Group	Pretreatment	Difference zymosan–PBS	P value compared with PBS group	P value compared with ethanol group	P value DEX compared with CpdA group
1	PBS	2.02 ± 0.30		0.381 (NS)
2	Ethanol	1.89 ± 0.23	0.381 (NS)
3	DEX	1.20 ± 0.39	0.0009 (***)	0.0017 (**)
4	CpdA	1.07 ± 0.42	0.0004 (***)	0.0007 (***)	0.5596 (NS)

Mice were injected s.c. with zymosan in the footpad, and swelling was determined at 24 h after the injection. Pretreatment with CpdA, DEX, or solvent was for 30 min. Means ± SD were compared with a Student t test. ** and ***, 0.001 ≤ P < 0.01 and P < 0.001, respectively. NS, not significant.
