研究了大鼠悬尾模拟失重后动脉环对KCl和苯肾上腺素的收缩反应。观察腹主动脉、股动脉、颈总动脉。结果表明，收缩反应仅在后躯发生改变，这一发现可能为飞行后直立性不耐受的机制提供线索。
The contraction responses of arterial rings to KCl and phenylephrine were studied in rats following tail suspension to simulate weightlessness. The abdominal aorta, femoral artery, and common carotid artery were studied. Results indicated that contraction responses were altered in the hindquarter only, and this finding may provide a clue to the mechanisms involved in postflight orthostatic intolerance.
