title: [The enzymes of glutamate and organic phosphate metabolism in the saliva in fluorosis (clinical and experimental research)].
abstract: Activities of glutamic-oxalacetic transaminase, glutamate dehydrogenase, gamma-glutamyl transferase were reduced in unstimulated pooled saliva of 15-year-old adolescents with endemic fluorosis, vs. those without fluorosis. This point to reduced production of glutamate which is indispensable for bacterial growth. The activity of acid phosphatase in pooled stimulated with 1% pilocarpin saliva of rats fed a water ration with 5 and 20 mg/liter fluorine in comparison with control rats fed water with fluorine concentration of 0.21 mg/liter. Noteworthy that alkaline phosphatase activity was virtually unchanged at fluorine concentrations 5 and 20 mg/liter in the water. The significance of the results as far as it regards the pathogenesis of caries and fluorosis is discussed.
