应用放免法测定了44例肺心病患者的血清β_2-m浓度。其值明显高于对照组;血β_2-m、BUN和Cr的阳性率分别为63.6%,33.3%和10.8%,以β_2-m阳性率最高,表明检测血清β_2-m是判断肺心病早期肾小球滤过功能受损的一种比较敏感、简便、可靠的方法。可作为肺心病并发肾脏损害的一项参考指标。
Serum β_2-m concentrations were determined in 44 patients with pulmonary heart disease by radioimmunoassay. The positive rates of β_2-m, BUN and Cr were 63.6%, 33.3% and 10.8%, respectively. The positive rate of β_2-m was the highest Ball filtration function impaired a more sensitive, simple and reliable method. Coronary heart disease can be used as a reference index of renal damage.
