Abstract

Bee venom BV from honey bee Apis mellifera L. has been used in oriental medicine and cosmetic ingredients because of its diverse pharmacological activities. In many studies, among BV components, phospholipase A2 PLA2 is known as a major player in BV-induced allergic reaction. Therefore, we removed PLA2 from BV using ultrafiltration and then investigated in vitro phototoxicity and in vivo skin sensitization of PLA2-free BV PBV in comparison with regular BV. The 3T3 neutral red uptake phototoxicity assay can be appropriated to identify the phototoxic effect of a test substance upon the exposure of ultraviolet A. Chlorpromazine, a positive control, showed high levels of photoirritation factor and mean photo effect values, while BV and PBV had less of these values. Local lymph node assay is an alternative method to evaluate skin sensitization potential of chemicals. BALB-c mice were treated with p-phenylenediamine PPD, positive control, BV, or PBV. In all of PPD concentrations, stimulation indexes SI as sensitizing potential of chemicals were ≥1.6, determined to be sensitizer, while SI levels of BV and PBV were below 1.6. Thus, based on these findings, we propose that both BV and PBV are nonphototoxic compounds and nonsensitizers.
