[The Anatomical Method of Isolating Central Ganglia from Oncomelania hupensis].

ABSTRACT

In this experiment the soft tissue of Oncomelania hupensis was obtained by breaking the shell with a hemostat. The central ganglia of 0. hupensis were then collected from the fresh soft tissue under a dissecting microscope. This method lays a base for studying the effects of molluscicides or various biological and physicochemical factors on the central ganglia of 0. hupensis.
