Neuropathic pain is considered as one of the most difficult types of pain to manage with conventional analgesics. EGb-761 is extracted from leaves of Ginkgo biloba and has analgesia and anti-inflammatory properties. This study aimed to examine the effect of EGb-761 on chronic constriction injury (CCI)-induced neuropathic pain behaviors, including thermal hyperalgesia and mechanical allodynia, and to explore the possible mechanisms underlying this action. ⋯ Moreover, the opioid antagonist naloxone prevented the effect of EGb-761 on thermal hyperalgesia and mechanical allodynia but did not influence the effect of EGb-761 on inflammatory cytokines. In conclusion, this study suggests that the potential of EGb-761 as a new analgesic for neuropathic pain treatment, and opioid system may be involved in the EGb-761-induced attenuation of thermal hyperalgesia and mechanical allodynia.

Triple-negative breast cancer (TNBC) is highly aggressive, resulting in poor prognosis. Chemotherapy of TNBC relies on anti-cancer agents with strong cytotoxicity, but it causes several side effects with recurrence. While combinational approaches of chemotherapeutics have been highlighted as a new treatment strategy for TNBC to reduce side effects, combinations of anti-cancer agents with herbal medicines have not been reported. ⋯ Our in vivo mouse xenograft tumor growth assays confirmed that combinational treatment of SH003 with doxorubicin repressed MDA-MB-231 tumor growth with no weight loss. Therefore, we conclude that the combinational treatment of SH003 with doxorubicin shows the synergism in TNBC treatment, and suggest that SH003 can be used together with conventional anti-cancer drugs in chemotherapeutic approaches.
