...U. Dunzendorfer; H.P. Zahradnik; K. Gerster 13,14-Dihydro-15-keto-prostaglandin F 2 α (13,14-DHK-PGF 2 α ) represents a stable product of degradation after pulmonary flow and it is shown to be reliably measured by radioimmunoassay. In patients with urogenital tumors, serum levels of 13,14-DHK-PGF 2...

...J.E. Altwein; R.F. Gittes Adult male rats have been subjected to cryptorchidism. After 9 weeks the testes were removed.
