【摘要】 应用膜富氧装置建立富氧室，使局部环境氧分压达到或接近海平面，并采用聚丙烯酰胺凝胶电泳和光谱扫描对富氧室中受试者进行血清乳酸脱氢酶同工酶（简称ＳＬＤＨ）活性和酶谱的观测，结果表明：进富氧室内ＳＬＤＨ总活力低于进富氧室前。ＳＬＤＨ同工酶谱均呈现了５条区带。各亚基含量基本接近平原。认为机体在富氧室内增氧后可以达到常氧环境的获氧水平。更多还原

【Abstract】 he enriched oxygen chamber was built up of membrane enriched oxygen set,in which PO₂ of local environment attained or approached to sea level.Moreover,the study of serum lactic dehy-drogenase isoenzyme（SLDH-isoen）and zymogram had been getting to sujects in enriched oxygenchamber by polyacrylamide gel electro phoresis and spectral scanning.It was indicated that thefive zones of SLDH-isoen were seen,but its degree of color was of different before and after twoweeks exposed enriched oxygen. The contents of subunits in SLDH-isoen were basically equalizedto lowlanders’ level after two weeks.更多还原
