海上氦氧150 m饱和-182 m巡回潜水对潜水员血浆AVP、DynA、ACTH和CRH含量的影响

目的　研究海上大深度饱和潜水对潜水员血浆精氨酸加压素 (AVP)、强啡肽 A(Dyn A)、促肾上腺皮质激素 (ACTH)和促皮质素释放激素 (CRH)含量的影响。方法　用放射免疫法检测 8名潜水员在饱和潜水前后血浆 AVP、Dyn A、ACTH和 CRH的含量。结果　饱和潜水后潜水员血浆 AVP(14 4 8.5± 16 33.6 ) ng/L、Dyn A(4 9.4± 36 .8) ng/L、ACTH(392 .1± 2 4 5 .6 ) ng/L 和 CRH(378.1±4 4 .6 ) ng/L 含量显著或非常显著地高于饱和潜水前 (P<0 .0 5或 <0 .0 1)。结论　大深度饱和潜水能引起潜水员血浆 AVP、Dyn A、ACTH和 CRH含量的改变 ,所观察的 4种神经肽可能参与了大深度饱和潜水引起的机体应激反应

The effects of the 150 m heliox saturation-182 m excursion diving in the open sea on the plasma AVP,Dyn A,ACTH and CRH contents in divers

Objective To study the effect of deep saturation diving on the plasma AVP,Dyn A,ACTH and CRH content in divers.Methods The plasma AVP,Dyn A,ACTH and CRH contents of eight divers before and after saturation diving were measured by radioimmunoassay.Results The contents of plasma AVP,Dyn A,ACTH and CRH in divers after saturation diving were significantly higher than thase before saturation diving( P <0 05 or <0 01).Conclusions The deep open sea saturation diving may change the contents of plasma AVP,Dyn A,ACTH and CRH in divers,and the neuropeptides may play a role in the stress induced by deep open sea saturation diving.
