Systemic administration of letrozole (Ltz, 10 mg/kg, sc) for 4 days reduced ATP-evoked MMemg responses in OvX rats. (A) Example of MMemg activity evoked by intra-TMJ injection of ATP (1 mM, 20 μl) in OvX (upper panel) and OvX + Ltz rats (lower panel). (B) Summary of integrated MMemg activity evoked by ATP in OvX and OvX + Ltz rats. Arrow indicates the time of intra-TMJ ATP stimulation; ∗∗p < 0.01 versus vehicle, b = p < 0.01 versus OvX + letrozole (OvX + Ltz).
