✦ Synopsis


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 normal control sera; bands V and VI were detectable in 31(73.8%) of 42 patients with PLC, but absent in 70 cases of other diseases. Bands V and VI may represent specific isoenzyme bands of PLC, comprising a new addition to the markers used in the diagnosis of this disease. By the same method, it was also found that the abnormal serum isoenzyme bands of PLC correspond to those found in the cord blood sera of the newborn and fetus. These abnormal isoenzymes diminish gradually after birth and all disappear when children reach the age of 10.

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

## 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

BACKGROUND. Steroid 5a-reductase is essential for the intracellular accumulation of dihydrotestosterone (DHT), which mediates androgen effects on target tissue. METHODS. In the present study, we describe the differential expression and cellular localization of 5a-reductase 1 and 2 isoenzymes in the
