[Relationship between fissured tongue with flow and components of saliva]

Observation on 30 patients with fissured tongue (FT) and 42 normal subjects, through the measurement of flow and the elements of saliva, pH value, the Na and K content, SIgA, it was shown that: in FT patients, the flow of saliva and pH decreased, while the Na/K ratio and the content of SIgA increased (each P < 0.01, compared with the normal). It was also showed that the formation of FT has to a certain extent something to do with the electrolyte disturbance in aqueous solution, malnutrition, as well as immunity and endocrinic function of patients.
