作者们应用敏感的荧光测定法测定了人癌组织和胚胎组织的5′-核苷酸磷脂酶活性(5′-NPD),并讨论了5′-NPD 的意义.材料:原发性肝癌组织2例,来自于各种原发癌灶的肝转移组织20例,具有肝转移症例的肝转移组织6例,大肠原发性癌组织1例。另外,妊娠5～10周的胚胎肝组织6例。 The authors used sensitive fluorometric assays to determine the 5′-nucleotide phospholipase activity (5′-NPD) in human cancer tissues and embryonic tissues, and discussed the significance of 5′-NPD. Materials: Primary liver cancer tissue In 2 cases, there were 20 cases of liver metastases from various primary foci, 6 cases of hepatic metastases with liver metastases, and 1 case of primary colorectal carcinoma. In addition, six cases of embryonic liver tissues were found at 5 to 10 weeks of gestation.
