The development of the frog was delayed under hypergravity condition. The total volume, cell size and cell number were reduced in pituitary, thyroid and cerebellum of hypergravity treated frogs. On the other hand, the morphological malfunctions of the treated frogs were recovered by the administration of thyroxin. These changes indicate that the drug recovers the declined functions. These results suggest that the thyroxin therapy rescues the hypofunction and dysfunction of the pituitary-thyroid axis from hypergravity., 資料番号: AA0063706064}, pages = {242--245}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {過重力によるニシツメガエル脳下垂体-甲状腺系の機能低下に対する甲状腺ホルモン投与の効果}, year = {2008} }
