[Mineral metabolism in man under altered gravitation].

Abstract

The book contains data about the functions and the metabolism of mineralized tissues, and the results of investigations of bone tissue and calcium metabolism during manned space missions and ground-based simulations. Consideration is given to the bone strength characteristics under experimental hypo- and hypergravity. The role of hormonal and physical/chemical factors in the mechanisms of iron control alterations in man during space missions of various lengths is analyzed. Evaluated is the efficiency of different countermeasures opposing the shifts in electrolyte exchange and bone mineral losses in these conditions. A concept is proposed for hypogravity-induced changes in the mineral metabolism and bone tissue status. The book is addressed to biologists, physiologists, biochemists, specialists in space biology and aerospace medicine.
