Effects of the egg extract on voltage-gated potassium channels in DRG neurons. Legend: Patch-clamp technique was used to measure the potassium currents of rat DRG neurons (n = 5). (A) 100 μg/mL egg extract inhibited about 13.96 ± 5.07% of the transient outward K+ currents. (B) 100 μg/mL egg extract had not obvious effect on the delayed rectifier K+ currents. (C) current–voltage curves of K+ currents in the presence and absence of 100 μg/mL egg extract. (D) steady-state activation curves of K+ channels in the presence and absence of 100 μg/mL egg exact.
