## Abstract By mediating the Ca^2+^ influx, Ca^2+^ channels play a central role in neurotransmission. Chemical agents that potentially interfere with Ca^2+^ homeostasis are potential toxic agents. In the present investigation, changes in Ca^2+^ influx into synaptosomes by organic forms of selenium
The effect of cholinergic agonists and antagonists on the intracellular free Ca2+ Concentration ([Ca2+li) of leech neuropile glial cells was investigated by use of iontophoretically injected fura-2. In neuropile glial cells, cholinergic agonists induced a marked increase in [Ca2+li that was inhibite
