title: [Effect of hypokinesia on the osteogenetic and hematopoietic functions of the bone marrow in mice. The ectopic bone model].
abstract: Using heterotrophic transplantation of syngenic bone marrow under the renal capsule, the effect of hypokinesia on osteogenic and hemopoietic cells-precursors as well as on de novo formed bone marrow was investigated. Altogether 16 experiments were performed, employing 260 recipients and 200 donors in two modifications: 1) bone marrow from animals exposed to hypokinesia for 3 days or 3 weeks (stage I or II of the general adaptation syndrome) was implanted to intact mice; 2) recipients who 5 to 7 day before exposure were implanted with bone marrow from intact donors were hypokinetic for 3 weeks. It was found that determined bone marrow precursors of osteogenic tissue as well as cells transferring hemopoietic microenvironment remained insensitive to hypokinesia. Three-week hypokinesia produced noticeable inhibition of osteogenesis and hemopoiesis. It is concluded that the stress-reaction plays the leading role in the changes that develop in hypokinetic mice.
