Background: Regarding to the important anti-inflammatory role of IL10 during inflammation process and hyperalgesia and edema variation during CFA-induced arthritis and also the increase of Spinal mu opioid receptor (mOR) expression, in this study researchers investigate the role of serum IL10 level on mOR expression and edema and hyperalgesia variation during different stages of Complete Freund`s Adjuvant (CFA) - induced arthritis in male Wistar rats.

Materials and Methods: Mono-arthritis was induced by CFA and inflammatory symptoms (hyperalgesia and edema) were assessed on 0, 3, 7, 14th and 21st days of study. Anti-IL10 was administered during the 21 days of study in different experimental groups. mOR expression were detected by western blotting on 0, 3,7, 14th and 21st days of study. Data was analyzed by SPSS statistical software version 19 with using one way ANOVA (post hoc Tokey's).

Results: Our results showed that anti-IL10 administration in AA group (Adjuvant Arthritis) caused an increase in the paw volume and hyperalgesia until 21st of study. Our study stated that there were no significant differences in spinal mOR expression between AA and AA+anti-IL10rats.

Conclusion: Our study confirmed that anti-IL10administration caused to hyperalgesia and edema during AA inflammation. Also these findings suggested that mOR expression increased in chronic phase of AA inflammation, however an increase in the level of spinal mu opioid receptor (mOR) expression during AA inflammation is not mediated directly via the effect of serum IL-10.
