Serotonin Receptor 2A/C Is Involved in Electroacupuncture Inhibition of Pain in an Osteoarthritis Rat Model

<table>Effect of a unilateral intra-articular injection of monosodium iodoacetate (3 mg/50 <i>μ</i>L/rat) on the weight-bearing ability of hind legs (<i>n</i> = 8). Note that iodoacetate-injected rats bore significantly less weight on the ipsilateral hind limb than did saline-injected rats. Abscissas: the time points from the 1st to the 7th day after iodoacetate; ordinate: body weight difference. ***<svg height="11.375" id="M5" style="vertical-align:-0.1638pt" version="1.1" viewbox="0 0 58.712502 11.375" width="58.712502" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
