Growth Hormone Regulation, Synthesis, and Secretion in Microgravity: III. Plasma Analysis (COS 1887-11)
Principal Investigator
Research Area:
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Wistar


Plasma hormone and biochemical analyses were performed either at NASA- Ames or by a clinical laboratory. Results of these tests were made available to all U.S. investigators to facilitate their evaluation of animal physiological status and interpretation of their data. For example, phosphorus, calcium, and alkaline phosphatase values are considered with bone studies; plasma proteins and albumin concentrations are discussed with the liver enzyme studies; and testosterone titers are discussed with the testes and pineal gland investigations.
