title: 5'-Nucleotide phosphodiesterase isozyme-V in health, in cancer, and in viral hepatitis.
abstract: An abnormal, fast-moving 5'-nucleotide phosphodiesterase isozyme was found in 90.0% of 20 Malaysian patients with primary hepatoma and in 23.5% of 391 Malaysian patients with various malignant diseases; it was also discovered in 42.9% of 14 Malaysian and American patients with clinically active hepatitis B infection; in 16.7% of 18 healthy American blood bank donors who were positive for hepatitis B surface antigen (HBsAg); in 13.9% of 287 healthy Malaysian blood bank donors, some positive for HBsAg; and in none of 160 healthy American donors who were negative for HBsAg. A correlation of this abnormal isozyme with hepatoma and with infectious hepatitis B is clearly evident.
