Fig. 3. Graphs illustrating the effect of diluted bee venom (dBV) treatment on myeloperoxidase (MPO) activity in pleural exudate. Intrapleural injection of carrageenan (CA) significantly increased the MPO activity in pleural exudate compared to that of sham animals (Sham). The CA mouse treated with 0.8 mg/kg dBV apipuncture of LU-5 (CA + BV-A 0.8) had significantly reduced MPO activity as compared to that of vehicle-treated CA mouse (CA + Veh) (p < 0.05). However, the CA mouse treated with 0.08 mg/kg dBV apipuncture of LU-5 (CA + BV-A 0.08) or 0.8 mg/kg dBV apipuncture of non-acupoint (CA + BV-NA 0.8) did not show significant changes in MPO activity compared to that of vehicle-treated CA mouse (CA + Veh). RFU, relative fluorescence units. ^***p < 0.001 compared to that of sham animals.
