流行性出血热患者尿液沉渣超活体染色镜检及其临床意义

Staining and microscopic examination of the sediments of urine from patients with epidemic hemorrhagic fever and their clinical significance

197 samples of the mine sediments from patients with epidemic hemorrhagic fever (EHF) were stained with toluidine blue-pararoseine and some of the samples were also stained with special immunoflurorescence in the present report, in order to study the cytological changes of the urine sediments in EHF patients. The results showed that the kinds and numbers of the tangible components in urine that were related to the severity of illness in the febrile, hypotensive and oliguric phases of EHF were more than those in the diuretic and convalescent phases. The appearence of abnormal red blood cells in large numbers accompanied by the wide and short casts and the kidney epithelial cells in cluster indicated the occurrence of acute renal failure. It was simultaneously shown that the detections of the viral inclusion bodies and the membrane-like substance in urine were of valuable in diagnosis. The above results suggested that the technique may be helpful for the diagnosis and evalutions of the severity and the prognosis of EHF.
