Uptake of injected [14C] adrenaline in denervated and in normally innervated submaxillary glands of the cat.

Radioactive adrenaline was injected into cats after one submaxillary gland had been denervated, either by section of the chorda-lingual nerve or by excision of the superior cervical ganglion. No indication was found that the supersensitivity caused by denervation was due to a greater uptake of adrenaline in the denervated gland. Stimulation of the chorda tympani greatly increased the amounts of radioactive adrenaline taken up by normally innervated submaxillary glands.
