—The aim of the experiments was to determine whether a direct correlation exists between cholinergic transmission and zinc‐iodide‐osmium (ZIO) positivity of the synaptic vesicles of the preganglionic terminals in sympathetic ganglia of the cat. It was found that hemicholinium (HC‐3) pretreatment with or without preganglionic stimulation did not cause any significant changes in the ZIO positivity of cholinergic nerve terminals. The authors suppose that there is no direct relation between the ZIO positivity of axon terminals and the functioning of cholinergic transmission.
