Clinical studies now give evidence that measurements of urinary LDH may be a criterion equal to the isotope nephrogram (ING) in considering this disease. Patients with a \"mobile\" kidney verified by i.v. pyelography were examined by an ING and a 1-day test for urinary LDH. In accordance with periodic kidney displacement total urinary LDH activities were measured in a 8-h urine volume in the supine position and a 8-h urine volume in the erect position of the patients. Evaluations were all expressed as percentage increase of LDH activity of the patient in the erect versus supine position and correlated with his ING-pattern. Among 45 nephroptotic individuals 34 showed, in accordance with a pathological ING, a mean LDH increase of more than a 100%. Eleven individuals had normal INGs and less than 20% increase equal to a group of 16 normal controls. We postulated a 30% increase as the upper limit between normal and pathological urinary LDH. The percentage distribution of isoenzymes was also altered within the pathological LDH range: LDH-I, which increases in normal controls, now decreased in nephroptotic patients. LDH-IV and V, which decrease in controls, now increased. Homomeric isoenzymes obviously show reciprocal behavior. The degree of kidney descent in cm does not correlate with percentage increase of urinary LDH, i.e. it is not a criterion for pathogenicity. Biopsies taken during nephropexy revealed that from an anamnestic duration of 50 weeks onwards the kidney is significantly affected and tissue damages become evident. If patients were re-investigated after nephropexy they showed normal i.v. pyelograms and normal LDH and no longer had clinical symptoms.</p>","PeriodicalId":72742,"journal":{"name":"Current problems in clinical biochemistry","volume":" 9","pages":"44-55"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11652492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Isolation and renal localisation of urokinase. 尿激酶的分离和肾定位。

{"title":"Isolation and renal localisation of urokinase.","authors":"K Andrassy,&nbsp;E Ritz","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Physico-chemical characteristics of urokinase in urine were studied by immunological and chemical methods. By agar zone electrophoresis, commercial urokinase preparations could be separated into an anodic and cathodic fraction. The latter reacted with urokinase antibodies with two precipitation bands. Band I displayed the major part of urokinase activity and migrated as a beta-globulin with a molecular weight of 32,000 daltons. Band II showed immunological identity with human serum, human albumin, alpha-2-macroglobulin and alpha-2-HS-glycoprotein. The specific activity of the cathodic fractions was up to 80,000 ploug units/mg protein. The ratio esterase/fibrinolytic activity did not change during the purification procedure. Further purification of the fractions with higher specific activity by affinity chromatography was unable to eliminate material cross reacting with human antisera (Band II). These findings permit the conclusion, that urokinase activity in urine is not confined to a homogeneous protein fraction. Activity is found both in a low molecular weight fraction and in a high molecular weight complex which contains serum proteins. These cannot be removed by exhaustive purification procedures and may play an important role in stabilizing and/or protecting urinary urokinase against proteolytic degradation. With Todd's technique diffuse fibrinolytic activity could be demonstrated in the kidney in the iuxtamedullary border region, (venae arcuatae, venae interlobulares, vasa recta) and in the epithelium of the calyces. Urokinase activity was specifically blocked by highly purified urokinase antibodies and could thus be distinguished from nonspecific proteolytic activity. The topographic relationship to medulla and uroepithelium may point to a role of urokinase in maintaining patency in slow flow systems.</p>","PeriodicalId":72742,"journal":{"name":"Current problems in clinical biochemistry","volume":" 9","pages":"330-41"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11328859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
