渗出性与漏出性胸腹水鉴别研究

目的比较蛋白区带电泳分析和紫外分光光度扫描鉴别漏出性与渗出性胸腹水效果。方法采用蛋白区带电泳分析和紫外分光光度扫描方法对13例肝硬化的病人的漏出液和32例渗出液标本（包括肺炎12例、肺结核9例、肺部恶性肿瘤11例）进行测定。结果蛋白区带电泳漏出液和渗出液,均能分出典型的Alb、α1、α2β和γ球蛋白五条带,各条带的百分含量差异无统计学意义（P〉0.05）。紫外分光光度扫描在（208±3.5）nm波长下,渗出液的吸收度为1.986±0.162明显高于漏出液的1.505±0.342,在（280±2）nm波长下,渗出液为0.184±0.075,漏出液为0.093±0.059,漏出液与渗出液吸光度比较有差异统计学意义（t=2.485,P=0.027,P〈0.05）。结论蛋白区带电泳方法难于鉴别漏出性和渗出性胸腹水。紫外分光光度扫描208nm波长处的吸光度则可以作为鉴别漏出液和渗出液的一个参考指标。

Protein zone electropgresis can not differentiate character between transudates and exudates

Objective to investigate whether to distinguish transudates or exudates by protein zone electrophresis.Methods 13 transudates(hepatocirrhosis patients and 32 exudates(include pneumonia patients,pulmonary tuberculosis patients and lung cancer patients) are analyzed by protein zone electrophresis.Results protein zone electrophresis of exudates and transudates are not significant different.Conclusion Protein zone electrophresis can't differentiate character between transudates and exudates.
