酶学作为肿瘤诊断指标已有半个多世纪的历史。近年来对同工酶深入而广泛的研究,提高了诊断的敏感性和特异性。本文从临床应用的角度,将几种重要的酶作一概述。一、乳酸脱氢酶(EC 1.1.1.27,LDH)乳酸脱氢酶是一种重要的糖酵解酶,广泛存在于动物细胞的可溶部分。 Enzymology has been a tumor diagnostic indicator for more than half a century. In recent years, extensive and extensive research on isozymes has improved the sensitivity and specificity of diagnosis. This article gives an overview of several important enzymes from the perspective of clinical application. 1. Lactate dehydrogenase (EC 1.1.1.27, LDH) Lactate dehydrogenase is an important glycolytic enzyme that is widely present in the soluble part of animal cells.
