为观察特技飞行对胰岛素、皮质醇、血管紧张素Ⅱ和胃泌素等激素的影响。20名健康男性飞行员(年龄24~30岁),复杂特技飞行时最大加速度为+6.0Gz,分别在飞行前2h,飞行后即刻、6h及飞行后24h采血。用放射免疫法测定上述激素。结果发现,飞行后即刻血清胰岛素含量(26.4±3.68μIU/ml)较飞行前(13.1±0.48μIU/ml)有明显升高(P<0.01),飞行后24h胰岛素含量(17.2±1.37μIU/ml)明显下降,与飞行后即刻比较有显著性差异(P<0.05),但与飞行前比较,无显著性差异(P>0.05)。飞行后即刻6h血清胃泌素明显升高(96.4±22.0,110.7±28。7pg/ml)与飞行前(35.3±15,0pg/ml比较,有显著差异(P<0.05)。飞行后24h血清胃泌素明显下降,与飞行后即刻比较有显著差异(P<0.05)。飞行前后血清皮质醇和血管紧张素Ⅱ均无显著性变化(P>0.05)。飞行后即刻胰岛素及胃泌素含量均明显高于飞行后24h,二者同为上午10时抽取的标本,说明其升高不是正常日节律所致,与饮食亦无明显关系。有研究发现,特技飞行后即刻血液中胃动素含量明显升高,胃动素能促进胰岛?
To observe the effects of aerobatics on hormones such as insulin, cortisol, angiotensin II and gastrin. Twenty healthy male pilots (aged 24 to 30 years old) experienced a maximum acceleration of + 6.0Gz during complex aerobatics, which were collected 2 hours before flight, 6 hours after flight, and 6 hours after flight respectively. The above hormones were determined by radioimmunoassay. The results showed that the serum insulin level immediately after flight (26.4 ± 3.68μIU / ml) was significantly higher than that before flight (13.1 ± 0.48μIU / ml) (P <0.01) (17.2 ± 1.37μIU / ml) decreased significantly (P <0.05), but there was no significant difference compared with that before flight (P> 0.05). Serum gastrin significantly increased at 6 h after flight (96.4 ± 22.0, 110.7 ± 28.7 pg / ml) compared with pre-flight (35.3 ± 15,0 pg / ml, P (P <0.05) .Serum gastrin decreased obviously after flight (P <0.05), there was no significant change in serum cortisol and angiotensin Ⅱ before and after flight (P> 0) .05) .The content of insulin and gastrin immediately after flight were significantly higher than that of 24h after flight, both of which were the same as the samples taken at 10 o’clock in the morning, indicating that the increase was not caused by the rhythm of normal day and had no obvious relationship with diet. A study found that aerobic immediately after the flight of blood motilin was significantly increased, motilin can promote islet?
