Abstract
SummaryStimulation of the rat parotid gland was effected by pilocarpine administration immediately following removal of one superior cervical ganglion and saliva was collected from the denervated gland and contra-lateral neurally intact mate. In this fashion it was possible to evaluate the effects of sympathetic and parasympathetic stimulation on the secretory responses of several proteins in parotid saliva. The flow rate of saliva obtained with cholinergic stimulation was higher than that with adrenergic stimulation. On the other hand, stimulation of adrenergic receptors caused secretion of total protein and amylase from the gland, in appreciably higher concentration than that elicited in response to cholinergic stimulation. Amylase level in secretion obtained from the neurally intact parotid gland immediately following pilocarpine injection was about 20 times that of the sympathectomized gland and gradually decreased with time reaching a level of about 4 times that of the denervated mate after 45 min.
