## Potent and novel fibrinolytic enzymes (lumbrokinase [LK]) were extracted from the earthworm, Lumbricus rubellus. These enzymes were very stable and showed greater antithrombotic activity than other currently used fibrinolytic proteins. An LK fraction showing the most potent fibrinolytic activi

Surfaces of commercial polyurethanes (PUS) were modified by poly(ethy1ene oxide) (PEO) grafting and/or heparin immobilization f o r l o n g -t e r m biomedical applications. PU surfaces were treated with diisocyanate and then reacted with PEO or heparin. The heparin immobilized by various methods on
Ah&act-Surface acidity of charcoals prepared by the carbonisation of PVDC, PVC, Saran, PF and UF polymers has been determined by titration with sodium hydroxide and sodium ethoxide. The surface acidity as determined by titration with 0.2N sodium hydroxide solution is found to be almost exactly equiv
## SYNOPSIS A polyester-urethane was synthesized by the reaction of 2,4-toluylene diisocyanate (TDI) with poly(buty1ene glycol adipate) (PBGAD) using 1,4-butanediol (BDO) as a chain extender. Atomic force microscopy was employed to examine the surface morphologies of polyurethane (PU) films formed
