为了探讨飞行学员在飞行应激下,消化道激素的变化以及与胃肠疾病关系。我们选择初教团飞行学员首次单飞前后胃动素(MOT)含量的变化进行观察。现报告如下。 初教团飞行学员200名,均为男性,平均年龄19岁,首次单飞前1h及飞行后0.5h内各抽静脉血2ml,与健康青年40名对照。胃动素试剂盒由解放军总医院提供,采用放免法测定,样本实验浓度为样品测定值乘以调整pH时的稀释倍数。 健康人组血MOT含量:302±42pg/ml。飞行学员单飞前血MOT为:334±38 pg/ml。两组比较无显著性差异(P>0.05)。飞行学员单飞后血MOT含量为:542±48 pg/ml,较健康人组及飞行前均有明显增高,统计学处理均有显著性差异(P<0.05,P<0.01)。
In order to explore the flight students under flight stress, changes in gastrointestinal hormones and gastrointestinal diseases. We select the first group flight pilot before and after the first solo flight motilin (MOT) content changes were observed. The report is as follows. The first group of 200 flight students, both men, mean age 19 years old, 1h before the first solo and within 0.5h after each pumping venous blood 2ml, and 40 healthy young control. Motilin kit provided by the PLA General Hospital, using radioimmunoassay method, the sample concentration of the sample measured value multiplied by the dilution of the pH adjustment. Healthy human blood MOT content: 302 ± 42pg / ml. Flight trainee solo pre-blood MOT: 334 ± 38 pg / ml. There was no significant difference between the two groups (P> 0.05). The levels of MOT in flight students after solo flight were 542 ± 48 pg / ml, which were significantly higher than those in healthy subjects and before flight. Statistical analysis showed significant differences (P <0.05, P <0.01).
