我们对33例婴幼儿肺炎患儿进行乳酸脱氢酶同工酶(LDHi)活性测定,观察肺炎LDHi活性的变化,探讨其临床实用价值。33例肺炎患儿均符合1987年卫生部颁发的小儿肺炎诊断标准。分别于入院次日和恢复期空腹抽血,经分离血清,用琼脂糖凝胶电泳法测定。两次测定结果LDHi异常均以LDH_1>LDH_2及LDH_2增高为最多。
We measured the activity of lactate dehydrogenase isoenzyme (LDHi) in 33 cases of infantile pneumonia and observed the changes of LDHi activity in pneumonia, and discussed its clinical value. 33 cases of children with pneumonia are in line with the 1987 Ministry of Health issued the diagnostic criteria for pediatric pneumonia. Fasting blood was collected on the next day after admission and in convalescence, respectively. Serum was separated and determined by agarose gel electrophoresis. The results of two tests showed that the abnormality of LDHi was the highest in LDH_1> LDH_2 and LDH_2.
