Hyaluronan Does Not Affect Bupivacaine’s Inhibitory Action on Voltage-Gated Potassium Channel Activities in Bovine Articular Chondrocytes

Representative whole cell patch clamp recordings showing outward currents elicited at 150 mV with holding for 200 ms. Bovine articular chondrocytes were treated with PBS (a), 0.25% bupivacaine for 5 minutes (b), 0.25% bupivacaine for 10 minutes (c), and cesium (potassium channel blocker) (d).
