From: Nelumbo nucifera leaves extracts inhibit mouse airway smooth muscle contraction
AELL inhibits ACh-induced precontraction of mouse ASM. a ACh induced a steady-state contraction in a mouse tracheal ring, which was inhibited by AELL in a concentration-dependent manner. b Dose-relaxation curve of AELL based on the results of 7 different experiments shown in (a). c ACh induced a steady contraction even in the presence of nifedipine; however, it was partially inhibited by AELL. d Comparison of the relaxant effects of nifedipine and AELL on ACh-induced contraction. NS represents no significance. * represents p < 0.05
