For the investigation of the stability of purified bee venom(PBV) during the treatment in the temperature range of 50℃ to 120℃ for 24 hours, respectively, melittin contents, antibacterial effects, and cell regenerations were investigated. The changes in the melittin contents of PBV were not significantly different by treatment temperature below 70℃ for 24 houes and 80℃ for 4 hours. However the melttin contents is great decline after 24 hours above 80℃ for 24 hours. Antibacterial effects is not change below 80℃ for 4 houes but significantly decrease above 80℃ for 24 hours. Cell regenerations of PBV on human dermal fibroblast decreased at 80℃ for 24 houes, showing a significant difference from the below 80℃ for 4 houes. Through the temperature stability of PBV results of this study, it was treated that the melittin contents, antibacterial effects and cell regeneration effects of PBV could be maintained above 80℃ for 4 hours.
