山道年的作用方式和作用部位已有很多报道,由于选用的虫种、虫体标本的部位、山道年的浓度各不相同,其结果不尽一致,迄今尚未得出统一的结论。本文作者报道了山道年用于广州管圆线虫、猪蛔虫等的结果。实验所用的寄生线虫均为雌性成虫,采用广州管圆线虫整体标本和按Baldwin(1943)法制作的头部切除神经环标本(把虫体的两端切除 There are many reports about the mode of action and function site of the mountain year. Due to the selected insect species, the specimen of the worm body and the concentration of the mountain year are different, the results are not consistent and so far no unified conclusion has been reached yet. The authors reported the results of the year of the mountain pathways for C. angularis and T. gondii. The parasitic nematodes used in the experiments were all female adults. The specimens were collected from the whole body of C. elegans and the excision of the nerve ring by Baldwin (1943)
