Quantitative Analysis of Selected Bone Parameters: Bone Elongation Rate and Bone Mass in Metaphysis of Long Bones (COS 1129-16)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Wistar


The purpose of this study was to determine whether bone elongation rate and bone cell number in the metaphysis of long bones were altered by Cosmos 1129 space flight. An attempt was made to measure the rate of bone elongation directly in the proximal tibial and humeral metaphysis by the use of tetracycline labeling.
