Fig. 1From: Nelumbo nucifera leaves extracts inhibit mouse airway smooth muscle contractionAELL inhibits high K+-induced precontraction of mouse ASM. a High K+ induced a contraction in a tracheal ring, which was gradually inhibited by AELL. b The same experiments were performed in 9 tracheal rings/9 mice, and a dose-relaxation curve was constructed. c & d High K+-induced precontraction was inhibited by AELL (17.8 mg/mL), which was observed in 7 tracheal rings/7 mice. e The same contraction was blocked by nifedipine, a selective VDCC blocker.
