ABSTRACT Serum creatine kinase (CK) B subunit (CK-B) activity, as estimated by the enzymatic anti-M immunoinhibition method, and the CK isoenzyme pattern after agarose gel electrophoresis, were studied in 28 patients with advanced, untreated malignant disease. CK-B was above the decision limit, i.e. the discrimination limit used in the diagnosis of acute myocardial infarction (AMI), in 14 patients (50%). Electrophoresis demonstrated, besides CK-MM, an atypical, cathodically migrating CK band in 10 of these patients. This band may represent mitochondrial CK. The CK-BB isoenzyme was detected in 9 and CK-MB in 3 subjects. Histopathologic findings indicated that the occurrence of these isoenzymes was related to tumour burden and the overall severity of the disease. Survival among patients with CK-B elevation was shorter than among other patients. The present findings are relevant to the enzyme diagnosis of AMI and of potential significance for the evaluation of patients with known or suspected malignant tumours. 相似文献

目的了解胰淀粉酶测定的假阳性问题。方法对免疫抑制法测定胰淀粉酶试剂盒中的单克隆抗体抑制唾液淀粉酶的能力进行系列检测。结果该单克隆抗体对唾液淀粉酶的抑制率为91.7%,并推导出胰淀粉酶的校正公式。结论用免疫抑制法测定胰淀粉酶结果必须加以校正,否则就会出现AMYp的假阳性。 相似文献
