Abstract：
:The purpose of this study is to clarify involvement ratios between central and peripheral cyclooxygenase (COX)-2 in rat inflammatory pain models, by evaluating celecoxib and [6-chloro-2-(4-chlorobenzoyl)-1H-indol-3-yl]acetic acid (CIAA) on carrageenan-induced mechanical and thermal hyperalgesia. Celecoxib and CIAA exhibited ID(30) values with 1.5 and 7.7 mg/kg on mechanical hyperalgesia, respectively, and ID(25) values with 0.54 and 36 mg/kg on thermal hyperalgesia, respectively. By solving quadratic functional analysis with prostaglandin E(2) (PGE(2)) inhibitory activities, it was calculated that involvement ratios between central and peripheral COX-2 involvement were 0.47 and 0.53 on mechanical hyperalgesia, and 0.97 and 0.03 on thermal hyperalgesia, respectively. These data suggest that central and peripheral COX-2 are equally involved in mechanical hyperalgesia, while central COX-2 is predominantly involved in thermal hyperalgesia.
