The Influence of Flow Rate on the Concentration of Uric Acid in Human Parotid and Submandibular Saliva

Abstract

SYNOPSIS IN INTERLINGUA LE INFLUENTIA DEL VELOCITATE DEL FLUXO SUPER LE CONCENTRATION DE ACIDO URIC IN HUMAN SALIVA PAROTIDIC E SUBMANDIBULAR.-Esseva constatate un correlation inverse inter le concentration de acido uric e le velocitate del fluxo in saliva submandibular e parotidic. In saliva parotidic, le concentration de acido uric declinava ab 4,1 ± 0,43 mg per 100 ml a lente velocitates de fluxo ad 1,7 ± 0,28 mg per 100 ml a rapide velocitates de fluxo. Le concentrationes esseva plus basse in saliva submandibular, i.e., 3,3 ± 0,46 mg per 100 ml e 1,3 ± 0,12 mg per 100 ml, respectivemente.

In studios de acido uric, saliva deberea esser colligite quando le velocitate del fluxo es superior a 1 ml per minuta, viste que sub ille conditiones pauc variation occurre in le augmentos del concentration e precise mesurationes del rapiditate del fluxo non es necessari.
