Problem of double vegetative innervation of rabbit cornea.

The coagulation of the sensitive part of the Gasserian ganglion in rabbits did not cause the disappearance of acetylcholinesterase-positive nerve fibres in the corneal epithelium. Most of them were very well detectable 6 to 8 days after operation. The autors cannot exclude the possibility that the interval between the coagulation and the killing the animals could be too short for disappearance of acetylcholinesterase reaction, but they express the view, that another source of corneal innervation by cholinesterase positive nerve fibres is to be taken into consideration.
