用硫代胆碱法定位乙酰胆碱酯酶展示寄生鱼类的巴氏叶形吸虫神经系统结构。该虫神经系统由咽后的１对脑神经节向前后各发出３对纵神经干与其间的横神经及更细神经分支构成神经网络。纵行神经干由内至外分别是背神经干、腹神经干和侧神经干。前行神经干的末梢在口吸盘内形成神经环，后腹神经干的分支进入腹吸盘形成神经环
Locating Acetylcholinesterase Using Thiocholine to Display Neurospora Pasteurellae Pathogens in Parasitic Fishes. The insect nervous system from the posterior pharyngeal cranial ganglia issued before and after each of the three pairs of longitudinal nerve stem and the lateral nerve and the nerves between the branches constitute a neural network. Longitudinal nerve trunk, respectively, from the inside to the outside of the dorsal trunk, trunk and lateral trunk of the neural stem. Peripheral nerve trunk at the front of the sucker in the mouth to form a neural ring, the branch of the posterior neural stem into the abdominal sucker to form a nerve ring
