Expression of heat shock protein 72 (HSP72) after administration of anandamide (AEA) analyzed by Western blot. a Representative bands of HSP72 at baseline (BL), 6, 12, 24 and 48 h after administration of AEA (1 mg/kg). b Plots of relative density of HSP72 protein to BL against time after administration of AEA (AEA group) and vehicle (control group). Representative bands of HSP72 protein (c) and bars of relative density of HSP72 protein (d) at 24 h derived from control, experimental AEA-treated rats, CB1 receptor antagonist AM251-treated rats, AM251- and AEA-treated rats, CB2 receptor antagonist AM630-treated rats, and AM630- and AEA-treated rats. Data are relative density compared to that in the control group (n = 6). Data are mean ± SEM. *P < 0.05 versus control group
