...Werner A. Wuttke; Thomas Munsch; Joachim W. Deitmer ABSTRACT The effects of extracellular ATP on intracellular free Ca 2+ concentration ([Ca 2+ ] i ) and depolarization-induced elevations of [Ca 2+ ] i were investigated in salivary cells of the leech Haementeria ghilianii using the fluorescent Ca 2...

...Werner A. Wuttke; Thomas Munsch; Michael S. Berry ABSTRACT Intracellular pH (pHi) and membrane potential (E m ) of giant salivary gland cells of the leech, Haementeria ghilianii, were measured with double-barrelled, neutral-carrier, pH-sensitive microelectrodes. E m was -51±11.2 mV and pHi was 6.98...

...Werner A. Wuttke; Michael S. Berry ABSTRACT The giant salivary cells of Haementeria ghilianii are known to produce Cam-dependent action potentials and to release their secretory products in response to stimulation of the stomatogastric nerve. In this study, the electrophysiological effects of some...
