[Effect of the diet with different microelement composition on the state of alveolar and pelvic bones in rats].

During this experimental study with 6 week-old rats the rate of alveolar bone resorption increased with the balanced diet and drinking water containing 50 mg/l NaF, which is similar to the group of rats observed in case of periodontitis model with the same diet and supplemented with ammonium chloride 5 mg/kg. The mineral complex (Mg-sulfat, Zn-sulfat, Mr-sulfat, Na-citrat) 300 mg/kg possessing a pronounced anti acidosis effect when added to the same balanced diet and sodium fluoride in drinking water with the same concentration prevents resorption processes in the alveolar bone and reduces toxicity action of fluorides on the alveolar and pelvic bones by decreasing metabolic acidosis in the bone tissue.

[Effect of diet on alveolar bone loss in female ovariectomized rats of different age].

In experiments on female rats of different age after ovariectomy we have determined that mineral compound complexes "Vita" No. 1 (300 mg/kg) and "Vita" No. 2 (300 mg/kg) with an increased content of calcium (20 mg/kg) were important to be included into a balanced diet of ovariectomyzed rats of different age to prevent resorption of alveolar bone.

[An assessment of acid-base imbalance in body tissues and fluids].

Ions hydrogene concentration in fluids and tissues is one of the strict regulated physiological organism variables. Most common man and animal diseases are accompanied with compensated acid-base balance shift development. But diagnosis of metabolic acidosis and alkalosis with blood indices (pH, pCO2, HCO3) doesn't reflect true tissue condition that is connected not only with respiratory and excretion system functioning but with hypercompensation of metabolic processes.
