6-磷酸已糖异构酶(简称PHⅠ)广泛分布于人体组织,它位于细胞的胞质间隙内并催化6-磷酸果糖与6-磷酸葡萄糖之间的反应。已知血清中PHⅠ水平的改变对监视前列腺及乳腺癌的进展是有用的,对肝病也有某些鉴别诊断价值。有报告在心肌梗死后血清P HⅠ活性急剧增加,也有报告脑脊液中PHⅠ活性对细菌性脑膜炎亦有诊断意义。作者以往的研究已发现涎液的P HⅠ在诊断慢性涎腺炎中可能有意义。本文研究了年龄、性别、
6-phosphohexose isomerase (abbreviated as PHI) is widely distributed in human tissues. It is located in the cytoplasmic space of cells and catalyzes the reaction between 6-phosphofructose and glucose-6-phosphate. It is known that changes in serum PHI levels are useful for monitoring the progression of prostate and breast cancer, and also have some differential diagnostic value for liver disease. Serum PHI activity has been reported to increase dramatically after myocardial infarction. It has also been reported that PHI activity in cerebrospinal fluid is also of diagnostic significance for bacterial meningitis. The author’s previous studies have found that P HI in sputum may be of significance in the diagnosis of chronic parotitis. This article studies age, gender,
