Influence of some simulated factors of cosmic flight on mineral and protein metabolism in the maxillodental system of rats

Mineral and protein metabolic changes in hard tissues of the maxillodental system, as opposed to skeletal bone, were studied in model experiments simulating space flight, with extreme factors given solely or combined: hypergravitation, ionizing radiation, magnetically activated water. Alterations occurring in protein synthesis proved to be the key events, whereas those in individual mineral components were either insignificant or of secondary nature. Long-term ingestion of magnetically activated water reduced radiation susceptibility of metabolic processes in mineralized tissues, but affected unfavorably the complex of signs resulting from combined exposure to extreme factors. Administration of a radioprotective drug, Adeturone, in treatments involving acceleration plus radiation led to normalization or partial balancing of metabolic processes in the mineral and organic components of maxillodental hard tissues and skeletal bone. The evidence obtained adds thus an anti-osteolathyrogenic feature to the radioprotective characteristics of Adeturone
