采用放射免疫法对30例支气管肺炎、25例急性支气管炎患儿末梢血红细胞超氧化物歧化酶进行了检测。结果急性期两组患儿血超氧化物歧化酶均显著下降。恢复期支气管炎患儿血红细胞超氧化物歧化酶已恢复正常,但支气管肺炎患儿尚未完全恢复。研究提示急性下呼吸道感染时存在着显著机体抗氧化能力下降。
Radioimmunoassay was used to detect peripheral blood erythrocyte superoxide dismutase in 30 cases of bronchial pneumonia and 25 cases of acute bronchitis. Results Acute phase of children with blood superoxide dismutase were significantly decreased. Children with convalescent bronchiolitis erythrocyte superoxide dismutase has returned to normal, but children with bronchial pneumonia have not fully recovered. Research suggests that acute lower respiratory tract infection there is a significant reduction in body antioxidant capacity.
