作者采用经过Маркелов改进的Гелъм法测定了102例肺部慢性化脓性疾病患者血清乳酸脱氢酶(LDH)及其同功酶。102例中38例是肺脓肿,32例是支气管扩张,32例是Ⅱ级慢性肺炎。病人年龄16～65岁。作者发现总LDH活性增高者在102例中有69例,以支气管扩张病人最多,肺脓肿病人次之,慢性 The authors determined serum lactate dehydrogenase (LDH) and its isozymes in 102 patients with chronic pyogenic disease of the lung using Гелъм method, which was modified by Маркелов. Of the 102 cases, 38 were lung abscess, 32 were bronchiectasis, and 32 were grade II chronic pneumonia. The patient is 16 to 65 years old. The authors found that in 69 of 102 patients with elevated total LDH activity, patients with bronchiectasis were the most frequent, followed by patients with lung abscesses, followed by chronic
