The over-all conclusion that must be drawn from the disarrangement experiments are first, that motor coordination (and certain behavior patterns dependent upon it) is driven by a rigid, unalterable cycle of neurophysiological events inherent in a species' central nervous system; second, that larval, fetal, or embryonic tissues lack specialization; this enables these tissues to influence one another in such a way as to continue to play their originally assigned role despite certain arbitrary peripheral rearrangements.

全面性的结论，即必须先从未安排的实验描绘，动作协调（取决於它的某些行为模式）是僵硬的，像是不可改变的周期神经生理活动中，其中所固有物种的中枢神经系统；第二，那幼虫，胎儿或胚胎组织缺乏专业化，这使这些组织影响专业化的另一种方式，尽管某些周边重新排列，还是继续发挥其原来分配的作用。

The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

血HCG定量检测优于尿HCG的定性检测，但仅适用于活的或近期破裂胚胎组织；未婚、女扎、放环、有异位妊娠史者及近期绝经者仍是异位妊娠不可忽视的发病群体；认真的询问病史，及时行有效的辅助检查是降低误诊的有效方法。
