人体组织在正常时 ,氧化与抗氧化作用处于平衡状态 ,使细胞能进行正常生理活动。当体内产生炎症时造成机体处于应激状态 ,诱发产生大量氧自由基 ,进而导致体内脂质过氧化 ,引起抗氧化酶的变化。老年人肺炎急性期时机体抗氧化酶如何变化 ,与成年人及儿童肺炎的变化是否一致 ,尚 Normal human tissue, oxidation and anti-oxidation in a balanced state, so that cells can perform normal physiological activities. When the body produces inflammation when the body is in stress state, induced a large number of oxygen free radicals, which in turn lead to lipid peroxidation in the body, causing changes in antioxidant enzymes. In the acute phase of pneumonia in the elderly, how the changes of the body’s antioxidant enzymes are consistent with the changes of pneumonia in adults and children
