Simultaneous demonstration of cholinesterases and glyoxylic acid-induced fluorescence of catecholamines in stretch preparations.
A combined simultaneous method to demonstrate adrenergic nerves using glyoxylic acid-induced fluorescence and nerves showing cholinesterase activity using the thiocholine technique is described in whole-mount preparations. The subcutaneous fascia and the right atrium of the heart of the rat and guinea-pig were used as tissue specimens, and the innervation patterns of adrenergic and cholinergic nerves were demonstrated in UV and transmitted light. Technical points and the limitations of the method are discussed.
