The activity of cholinesterase was determined using modified Ellman's procedure. It was found that the ampullae contain the enzyme which is similar in its substrate-inhibitory specificity to acetylcholinesterase of vertebrates. The presence of acetylcholinesterase and N-cholinoreceptors (data from literature) in the ampullar walls suggests that non-synaptic cholinergic system is involved in the control of contractile activity of these nerve-free smooth muscle organs.
