Effect of superior cervical ganglionectomy on Harder (rat and rabbit) and Loewenthal (rat) glands]

An unilateral superior gangliectomy induce morphological changes in the way of an hypersecretory activity of the harderian gland. If the unmyelinised nervous system is not notably affected, some specific cytological aspects are undoubted. (In rats as in rabbits). On "harderised" spots in the outer orbital glands of rats, the same changes occur in the same delay (27 to 130 days).
