Zinc normally aids wound healing in terrestrial invertebrates. Wounding of the optic tentacle, foot tissue, and partial shell removal in Helix aspersa, a terrestrial gastropod, resulted in deposition of zinc in the wound area after 2 to 5 days. Increased zinc in Helix wound areas may be necessary to promote protein synthesis, collagen formation, and mitotic cell division (Ireland 1986).

PC12) cells. Inhibition of L-type Ca2+ currents by phenothiazine drug was also found in invertebrate neurons. Investigations performed by Cruzblanca et al. [266] revealed that TFP (5) caused reversible and dose-dependent reduction of L-type Ca2+ currents in Helix aspersa (brown snail) neurons. The efficacy of inactivation of this current was enhanced by this drug. The possibility that calcium currents were altered by the influence of TFP (5) on the protein kinase C (PKC) activity was excluded in this paper.

We carried out a similar series of experiments to those just described in the cockroach for snails Helix aspersa. The training set-up is shown in Fig. 12. In this case when we measured the ChE activity in the brains of the Experimental, Control and Resting snails we found a striking difference from that of the cockroaches. In the snail there...

Interest in the measurement of intracellular activities centres on transmembrane potentials and on the transport of ions across membranes. For example, lithium salts feature in the treatment of mania, but owing to the analytical problems little has been known of lithium accumulation or about its transport by nerve cell membranes. However, a recently developed microlithium electrode based on a liquid membrane sensor has established [280] an active transport of lithium ions out of Helix aspersa pallial ganglia and that at low external levels there is even less intracellular than extracellular lithium ions. It is therefore difficult to appreciate how lithium could function in an intracellular capacity to alter the neuronal properties in lithium psychiatric therapy [280].
