Abstract:
Objective(s):Cone snails are estimated to consist of up to ۷۰۰ species. The venom of these snails has yielded a rich source of novel peptides. This study was aimed to study the analgesic effect of Persian Gulf Conus textile and its comparison with morphine in mouse model. Materials and Methods: Samples were collected in Larak Island. The venom ducts were Isolated and kept on ice then homogenized. The mixture centrifuged at ۱۰۰۰۰ × g for ۲۰ min. Supernatant was considered as extracted venom. The protein profile of venom determined using ۱۵% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Venom was administered intraperitoneally (IP) to evaluate the LD۵۰ in Swiss albino mice. Different concentrations of Conus textile venom were injected intrathecally to mice to evaluate their analgesic effect in comparison to morphine. Injection was carried out between the L۵ and L۶ vertebrae. Differences between groups in the first and second phase were tested with Two-Way analysis of variance (ANOVA). Results: SDS-PAGE indicated ۱۲ bands ranged between ۶ and ۱۸۰ KDa. Finally, ten ng of Conus crude venom showed the best analgesic activity in formalin test. No death observed up to ۱۰۰ mg/kg. Analgesic activity of crude venom was more significant (P<۰.۰۵) in acute pain than inflammatory pain. The analgesic effect of ۱۰ ng Conus venom was the same as morphine for reduction of inflammatory pain (P=۰.۲۷). Conclusion: The venom of Persian Gulf Conus textile contains an analgesic component for reliving of acute pain which can lead to find an analgesic drug.
