Fig. 2From: Suppression of hyperexcitability of trigeminal nociceptive neurons associated with inflammatory hyperalgesia following systemic administration of lutein via inhibition of cyclooxygenase-2 cascade signalingComparison of change in CFA-inflammatory edema among naïve, inflamed, and inflamed with lutein administration rats. Each column shows the mean thickness of the whisker pad edematous area among three groups of rats. *, P < 0.05, naïve vs. inflamed, inflamed vs. inflamed at 3 days before lutein (10 mg/kg, i.p.) treatment, n = 8.
