Parotid saliva, submandibular saliva, and blood were collected from mongoloid and nonmongoloid populations. Salivary flow rates were determined and fluid samples were analyzed for various electrolytes. Ten samples of parotid saliva and serum were analyzed for total protein, creatinine, amylase, and uric acid. Parotid saliva of mongoloids showed some differences in composition, but serum showed only a higher level of uric acid.
