[Salivary glands secretory activity in patients with terminal chronic renal insufficiency on programmed dialysis].
Saliva secretion speed and some biochemical mixed saliva characteristics were studied in patients with a terminal stage of chronic renal insufficiency. There was reduction of salivary function by more than 2 times and an increase of urea and creatinine concentrations in mixed saliva before the dialysis start. In case of higher urea content in saliva the speed of salivation was the highest that could evidence for an adequate response of the salivary glands to toxic action of nitrogen metabolism end products. The function restoration after hemodialysis took place not in all the patients. Amino acid catabolism product concentration in mixed saliva fell after hemodialysis and correlated directly with the amount of urea and creatinine in blood plasma. It took place also in "urea ricochet" when its content in blood increased sharply 1 hour after hemodialysis due to urea washout from the tissues.
