Abstract

The results of determination of the serum 5′‐NPDase isozymes in 95 cases of primary liver carcinoma and other kinds of liver disase are presented. The 5′‐NPDase‐V was positive in 83.2% of primary liver cancer cases. This test might be a useful supplement to AFP determination, especially in AFP‐negative liver cancer patients. In most patients who had undergone successful liver resection for primary carconoma, the test became negative. A positive 5′‐NPDase‐V test in patients with cancers elsewhere in the body may suggest liver metastasis. In addition, this test may be of some help in the differentiation of primary liver cancer from other kinds of liver disease. The problem of “false‐positive” results of this test is discussed.

In 1986, we reported that abnormal 5'-nucleotide phosphodiesterase (5'-NP) (oligonucleate: 5'-nucleotidohydrolase, EC 3.1.4.1) isoenzymes (5'-NP I and 5'-NP V +VI) were observed in the serum of patients with liver cancer. The results of the present study show that the 5'-NP I positivity rate is 99.2

5'-nucleotide phosphodiesterase (5'-NP) isoenzymes were separated from the serum of human primary liver cancer (PLC) patients by 4-20% tubular polyacrylamide gel gradient electrophoresis. Electrophoresis showed 11 isoenzymes in which bands I, V and VI (from anode to cathode) were all absent in 125 n

Precise diagnosis of well-differentiated hepatocellular carcinoma (HCC) is sometimes difficult to establish. Telomerase activity was examined by telomeric-repeat-amplification protocol (TRAP) in 37 HCC nodules smaller than 3 cm in diameter, including 24 fine-needle-aspiration biopsy specimens, 22 no

## Abstract The activity of phosphodiesterases (PDEs) is associated with a wide variety of diseases and an intense effort toward the development of specific PDEs inhibitors has been generated for the last years. They are the enzymes responsible for the hydrolysis of intracellular cyclic adenosine a
