[Effect of fluorine in drinking water of varying hardness on protein-mineral metabolism of mineralized tissues of rats maintained on a sugar diet].
Variations of mineral and protein metabolism in calcified tissues were studied using 32P, 45Ca and 35S methionine in the rats on sugar diet and water of different hardness with F and without it. Hard drinking water without F like soft water and water of medium hardness with F affect metabolism in mineralized tissues preventing the development of carious process. Incorporation of 32P and 45Ca to mineralized tissues, specific radioactivity of 32P and 35S methionine of tooth and bone proteins are lower in rats which drank soft water without F. These parameters increase in rats which received hard water without F almost to the level of animals which received water with F. Ways of the effect of Ca2+ Mg2+ and F on protein and mineral metabolism of calcified tissues of rats on sugar diet (including proteins (osteo-induced, etc., which initiate mineralization) and enzymes are considered.
