Effects of paclitaxel (PTX) and Goshajinkigan (GJG) on tumor-induced mechanical allodynia in mice with breast cancer. PTX (10 and 20 mg/kg) and vehicle (VH1) were injected intraperitoneally, and GJG (1 g/kg) and vehicle (VH2) were administered orally, as described in Figure 1 legend. The evaluation of pain-related responses using a von Frey filament was performed before drug administration every day. (a) The site of allodynia evaluation. ((b), (c)) Time-course of allodynia induced by tumor with or without PTX and GJG administration. Values represent the means ± SEM. Figures in parentheses indicate the number of animals.
