Amylase-secretory responses to sympathetic nerve impulses in the rat parotid gland following partial sympathetic ganglionectomy.
Some sympathetic axons reach the parotid gland from the contralateral sympathetic chain. Such contralateral nerves were stimulated and saliva secreted after intravenous injections of methacholine was collected from the parotid duct at various times after removal of the ipsilateral superior cervical ganglion. The secretion of amylase caused by sympathetic nerve stimulation was greatly increased three days after the sympathectomy and even more after ten weeks. This effect is attributed to denervation supersensitivity, prejunctional after three days and, in addition, postjunctional later.
