title: [The physicochemical properties of the mixed saliva and parotid secretion of patients with chronic parenchymatous parotitis and of persons who have a history of earlier acute parotitis].
abstract: Eighty-five patients with chronic parenchymatous parotitis and 73 convalescents after epidemic or acute nonepidemic parotitis were examined for their secretory function and some physicochemical characteristics of mixed saliva and parotid secretion (secretion rate, pH, viscosity, transparency, electrokinetic properties). A significant reduction of salivary secretion volume and rate were detected, as were pH shift to the acid direction and increased viscosity of both saliva and parotid secretion, reduced transparency and increased electric conductivity in the patients with chronic parenchymatous parotitis, more marked in those with an active course of the disease. Such changes were absent in convalescents after epidemic or acute nonepidemic parotitis. This permits a conclusion that none of these two conditions may be responsible for the development of a chronic inflammation of the parotid gland. The detected changes in physicochemical parameters of the saliva in chronic parenchymatous parotitis supplement the known data on the pathogenesis of this condition and may be used in the diagnosis and prediction of the course and outcome of sialadenitis. The authors emphasize the desirability of therapeutic and prophylactic measures during remissions of chronic parenchymatous parotitis.
