[On the secretion pressure of the human parotid gland (author's transl)].

The secretion pressure as well as the speed of resorption for saliva and water in the parotid gland is studied by electromanometry in 40 male and 14 female healthy persons on stop-flow conditions in rest and after gustatory stimulation with lemon juice. The course of intraglandular pressure after stoppage and retrograde instillation of pure water is demonstrated by typical diagrams. The essentials are discussed. The mutual relations of the measured parameters and those existing with the age are examined by means of simple correlation and linear regression analysis. Results of this analysis show that the pressure of resting secretion diminishes due to increasing age. With increasing secretory activity of the parotid gland the speed of intraglandular resorption increases, too. Pure water with be resorpted more quickly than saliva. Sex differences are not existing.
