在20～22岁的青年中,进行了低压性缺氧(低压舱,相当于2,000和4,000m高度)对某些血清酶活性影响的研究。在经受低压性缺氧之前和低压性缺氧两小时之后,分别采血,进行了谷草转氨酶(GOT)、谷丙转氨酶(GPT)、谷氨酸脱氢酶(GDH)、肌酸磷酸激酶(CPK)、乙酰胆硷酯酶(ACE)和三磷酸腺苷酶(ATP-ase)化验。血清GPT、GDH、CPK和ACE没有显著的变化,但是,在2,000m高度,GOT明显增高;在4,000m时没有任何明显的变化。ATP-ase在4,000m高度明显下降,而在2,000m高度时仅轻度下降。两个受检者在缺氧和正常情况下,均出现酶的 In young people aged 20 to 22 years, studies of the effects of hypobaric hypoxia (low pressure chambers, equivalent to 2,000 and 4,000 m altitude) on the activity of certain serum enzymes were performed. Two hours after hypobaric hypoxia and hypobaric hypoxia, blood samples were collected for GOT, GPT, GDH and CPK ), Acetylcholinesterase (ACE) and ATP-ase assays. There was no significant change in serum GPT, GDH, CPK and ACE, however, at 2,000 m, GOT was significantly increased; at 4,000 m, there was no significant change. ATP-ase decreased significantly at a height of 4,000 m, but only slightly decreased at a height of 2,000 m. Both subjects showed enzyme in both hypoxia and normal conditions
