There is disclosed a method for stopping bleeding and forming black blood
coagulation on contact, comprising administering powdered
L-threo-hex-2-enono-1,4-lactone thereof to a bleeding site in an amount of
0.1568 grams for every milliliter of blood. This includes cancer, liver
diseases and hemophiliac bleeding in patients or animals in whom the
thrombocytopenia or coagulation factors disorders result. Accordingly, the
said mechanism of action of powdered L-threo-hex-2-enono-1,4-lactone in
the formation of blood coagulation on contact is the unique common pathway
for all blood coagulations, which overturns the mechanisms of intrinsic
and extrinsic pathways for blood coagulation cascade being the unique
pathways for blood coagulation in which the coagulation factors 1, 2, 5,
7, 8, 9, 10 and platelet factor 3 are essential for the pathways.
