Summary
Previous fluorescence histochemical studies have shown that extrinsic denervation causes a disappearance of adrenergic fibres from the gut wall. However, in the present work, adrenergic terminals persisted in the myenteric plexus of the guinea-pig proximal colon following interruption of paravascular nerves. Fluorescent cell bodies are found in the myenteric plexus. The fluorescence reaction of the cells does not appear after reserpine treatment and is restored by α-methyl-noradrenaline.
