作者对84例无氮质潴留的活动性或非活动性慢性肾盂肾炎患者,在治疗前后测定血清铜蓝蛋白(ceruloplasmin)、结合珠蛋白(haptoglobin)和唾液酸(sialic acid)水平。对另一组145例慢性肾小球肾炎患者测定相同的指标,作为对照。结果:试验组(慢性肾盂肾炎)铜蓝蛋白水平稍有增高(59.03±6.15毫克％),而对照组(慢性肾小球肾炎)铜蓝蛋白水平在正常范围内(47.16±2.60 The authors tested serum ceruloplasmin, haptoglobin, and sialic acid levels in 84 patients with active or inactive chronic pyelonephritis without nitrogenous retention before and after treatment. Another group of 145 patients with chronic glomerulonephritis were measured in the same indicators as a control. RESULTS: The level of ceruloplasmin in the experimental group (chronic pyelonephritis) was slightly elevated (59.03 ± 6.15 mg%), while the level of ceruloplasmin in the control group (chronic glomerulonephritis) was within the normal range (47.16 ± 2.60
