Cholinesterases in single nerve cells isolated from the locus ceruleus and from nucleus of the facial nerve of the rat: a microgasometric study.
Cholinesterase activity in single nerve cell bodies isolated from the locus ceruleus and nucleus of the facial nerve of the rat was analyzed by the microgasometric method. Acetylcholinesterase activity is about the same in both types of cells. Nonspecific cholinesterase is present in noradrenergic cells of the locus ceruleus but not in the cholinergic cells of the nucleus of the facial nerve. The total activity of cholinesterases and the activity of acetylcholinesterase in nerve cell bodies isolated from the locus ceruleus remains practically unchanged from the tenth postnatal day until the age of 24 months. Depletion of noradrenaline by a high dose of reserpine does not influence the total activity of cholinesterases in nerve cell bodies of locus ceruleus.
