Summary

Pharmacological observations on the glutathione-induced feeding response in Hydra demonstrate that phorbol esters, calcium ionophore A 23187 and lithium ions significantly enhance and protract glutathione action, whereas polymixin B induces a dramatic shortening of the feeding response. An involvement of membrane phosphatidylinositol breakdown in the control of the feeding response is suggested.
