[The determination of the ureolytic and glycolytic activities of human oral fluid].

The authors describe a simple and rapid method for measuring urease and glycolytic activity of mixed saliva. It is based on alteration of the color of some acid-alkaline indicators during incubation of the saliva with appropriate substrata (carbohydrates and urea). Examinations of 32 normal subjects revealed that with the developed procedure, the reactions of carbohydrate fermentation and urea hydrolysis are rapidly detected in mixed saliva samples, the test taking approximately 20 min.

[Urea and ammonia in the saliva of patients with kidney diseases].

The findings indicated higher levels of salivary urea in group 1 and 2. Salivary and blood urea concentrations correlated, the proportions being 68%, 40.
