Extirpation of the pleurovisceral ganglia (PV) blocked egg-laying whereas reimplantation of PV or injection of a PV homogenate into PV-less animals restored the egg-laying capacity of the marine pulomonate, 0. verruculatum. Injection of PV homogenate induced egg-laying in intact, mature individuals

โฆ Synopsis
A search for endocrinological factors in 0.verruculatum revealed that three hours after right pleural ganglion extirpation blood chloride is significantly (P < o .o 1) sinked . Administration of right pleural ganglion homogenate (i gang/ animal) into depleuralised snails significantly (P < o .ooi) enhances the blood chloride level after three brs . Removal of the ganglia other than the right pleural provokes a significant (P < o .ol) decline in blood chloride profile in these animals . However, replacement therapy either via homogenate injection or reimplantation of the particular ganglion into extrapleural ganglionectomised animals is ineffective in restoring the chloride levels. It is argued that only right pleural ganglia control blood chloride via vascular channels .
