    Abstract:
    Bones of rats flown for 19 days onboard Cosmos-1129 were examined. The examination included bone mass, density, mineral composition, reconstruction parameters, and elemental composition at R + 1, R + 6, and R + 29. After flight the rats developed osteoporosis in the spongy structures of tubular bones and a smaller thickness of the cortical layer of the diaphysis; they showed no mineralization of the microstructures, a slight decrease of the Ca concentration, and a normal content of P. At R + 6 these changes progressively developed and at R + 29 they returned to normal.
