the specific activity of nicotinamide adenine dinucleotide-dependent 15-hydroxyprostaglandin dehydrogenase in hydatidiform mole tissue ( 0 to 1.2 nmol 15-ketoprostaglandin e2 formed x min-1 x mg-1 cytosolic protein ) and in choriocarcinoma cells ( 1.0 nmol 15-ketoprostaglandin e2 x min-1 x mg-1 protein ) was strikingly less than that found in normal placental tissue [ 11.4 +/- 2.3 ( s.e . ) nmol 15-ketoprostaglandin x min-1 x mg-1 protein ] .
