Averages of paw withdrawal latency (PWL) values (s) (both ipisilateral and contralateral), knee joint circumferences (cm), knee joint temperatures (°C), and spontaneous pain rating scores before (baseline) and 4 hours after a mixture of kaolin and carrageenan injection into the knee joint cavity of each rat. All values are expressed as mean ± S.E.M. (n = 23) except the pain score, which is reported as a median since it is not an interval scale.
