title: [Effect of prolonged administration of thyrocalcitonine on mineralization of regenerating bone after fracture].
abstract: A distinct effect on all the stages of regenerating bone mineralisation was observed after daily (within the experimental period) intramuscular administration of thyrocalcitonine with prolonged action (a complex with polyvinyl pyrrolidone) into male rat at a dose 2.5 un/kg of body weight. The drug caused an inhibitory effect on metabolism within the first 10 days of the experiment. Within 2-3 weeks after the fracture the intensity of metabolic processes was increased. Contents of calcium, phosphorus, sodium and potassium were markedly increased in liquid phase of the bone rissue. The synthesis of phosphoproteins, organic non-protein phosphates and the inorganic phosphate was also increased. The data obtained suggest that thyrocalcitonine caused a stimulating effect on aerobic resynthesis of macroergic phosphate containing substances and the increase in the functional activity of osteogenic cells.
