Species Studied
Scientific Name: Macaca mulatta Species: Monkey Strain: Rhesus


The problem of calcium loss from the body during space flight had been long recognized; however, little is known about the initiating mechanism of this loss. Two hypotheses have been suggested in explanation: 1) a primary increase in bone resorption due to decreased mechanical stress on the bone or 2) a primary renal calcium leak. This experiment was to measure the initial responses of the calcium homeostatic system in nonhuman primates subjected to the space flight environment.
