不同飞行条件下飞行员血清催乳素、雌二醇、醛固酮的变化

Comparative Observation of Serum Prolactin,Estradiol and Aldosterone in Pilots under Different Flight Stress

目的探讨不同飞行应激条件下飞行员血清催乳素、雌二醇、醛固酮水平的变化。方法应用放射免疫分析法,对40名飞行员按不同分组检测飞行训练前后血清催乳素、雌二醇、醛固酮水平,并进行对比分析。结果不同飞行时间、不同飞行场次、不同飞行载荷、不同飞行高度飞行后血清雌二醇水平分别为(137.98±15.89)pg/mL和(134.52±13.17)pg/mL、(131.59±17.45)pg/mL和(119.83±19.45)pg/mL、(132.26±14.90)pg/mL和(122.57±17.41)pg/mL、(126.67±14.85)pg/mL和(121.53±19.92)pg/mL,与飞行前比较差异有统计学意义(P<0.01和P<0.05);血清催乳素、醛固酮水平飞行前后比较差异无统计学意义(P>0.05)。结论在不同飞行应激条件下,战斗机飞行员飞行训练后血清雌二醇水平降低,血清催乳素、醛固酮水平无变化。

Objective To investigate the changes of serum prolactin,estradiol and aldosterone in pilots under different flight stress.Methods Using radioimmunoassay,serum prolactin,estradiol and aldosterone in 40 pilots from different groups were determined before and after flight training,and then analyzed comparatively.Results In different flight time,different flight schedule,different flight loads and different flight altituude,the serum estradiol in post-flight were（137.98±15.89）pg/mL and（134.52±13.17）pg/mL,（131.59±17.45）pg/mL and（119.83±19.45）pg/mL,（132.26±14.90）pg/mL and（122.57±17.41）pg/mL,（126.67±14.85）pg/mL and（121.53±19.92）pg/mL,respectively.Significantly lower serum estradiol was observed in post-flight compared with those in pre-flight.A significant difference was not observed between serum prolactin and serum aldosterone.Conclusion Under different flight stress,there is a significant decrease in serum estradiol of pilots,but no change in serum prolactin and serum aldosterone level.
