The rhythmical activity of the liver fluke was inhibited and those of chicken roundworm was stimulated by choline esters ( acetylcholine, carbacholine and acetyl-β-methylcholine) and eserine. 胆碱酯类(乙酰胆碱、氨甲酰胆碱和乙酰甲胆碱)及毒扁豆碱对肝片形吸虫呈抑制作用而对鸡蛔虫则呈兴奋作用。
Atropine was found to cause complete block on liver fluke and only partial block on chicken roundworm to the effect of choline esters. 硫酸阿托品能完全阻断胆碱酯类对肝片形吸虫的抑制作用,但只能部分阻断胆碱酯类对鸡蛔虫的兴奋作用。
