Experiments performed to demonstrate the participation of cholinergic synapses in retinal spreading depression (SD) have shown that: (1) acetylcholine (ACh) is liberated during SD, its concentration increasing up to 10(-4) mM in the superfusate of one eye cup; (2) the susceptibility of the retina to

โฆ Synopsis
The presence of acetylcholinesterase and choline acetyltransferase, enzymes involved in acetylcholine metabolism, has been shown in twelve species of rotifers . Both enzymes have been visualized by histochemical staining in live animals, and acetylcholinesterase was also isolated by acrylamide gel electrophoresis . All the known ganglia of rotifers as well as some sensory nerve endings have been found to contain these enzymes . Preliminary experiments aimed at the detection of norepinephrine and tyrosinase, an enzyme involved in catecholamine metabolism, were unsuccessful .

We investigated the effects of epithelial cells on excitatory cholinergic neurotransmission in dog trachea, to shed more light on the role of airway epithelial cells in regulating airway responsiveness. Airway epithelial cells were prepared by an enzymatic dissociation of the tracheal mucosa using p
