It is indicated that the most important diagnostic tests for DIC were Fbg, FDP, and AT III. DIC may have developed not only in patients with reduced Fbg but also in patients with normal or elevated Fbg. It is necessary to estimate the actual situations in the patients with DIC by utilizing sequential laboratory tests. In DIC, SDS-PAGE patterns of Fbg indicated the marked reduction of LMW Fbg, and the activated fibrin formation must be caused by the high affinity of thrombin for HMW Fbg. Changes in the immunoprecipitative second peak of AT III may indicate the binding of different serine proteases to AT III in DIC. Rapid and simple diagnostic tests for DIC are clinically required. An analysis of the TEG pattern using normal plasma mixed with the patient's plasma can indicate the presence of procoagulant activity in patient plasma. Such a laboratory test using TEG is the most useful and rapid diagnostic test in DIC. An anticoagulant effect of heparin therapy is determined by APTT and heparin levels. The antithrombotic effect of heparin therapy is determined by FPA as an immediate index and by Fbg, FDP, and AT III as a slow index.</p>","PeriodicalId":75590,"journal":{"name":"Bibliotheca haematologica","volume":" 49","pages":"173-80"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000408458","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17721693","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}

If the amount of soluble fibrin exceeds a certain threshold, soluble fibrin may precipitate or polymerize to fibrin clots. At this state, active fibrinolysis breaks down the precipitated fibrin to fibrinolytic degradation products preventing the preservation of fibrin. If the capacity of the fibrinolytic system is exhausted, or if fibrinolysis is inhibited, fibrin clots may be preserved, causing cell damage, as for instance bilateral renal cortical necrosis.</p>","PeriodicalId":75590,"journal":{"name":"Bibliotheca haematologica","volume":" 49","pages":"3-13"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000408441","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17721698","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}

Microthrombi in the former three types showed various degrees of thrombolysis. Failure of thrombolysis seemed to lead the organization of microthrombi. These morphological findings were considered to indicate the course of DIC and the degree of disappearance of the microthrombi in DIC. Microthrombi in the hepatic sinusoids and glomerular capillaries were studied with special reference to the removal processes of the microthrombi.
