Researchers will present information about Ciba-Geigy AG's Hirudin, a drug that prevents blood from clotting.

Hoechst recently built a plant north of Paris to make Hirudin, an anti-coagulant medication found naturally in leeches.

The wound will also continue to bleed for a while due to the anticoagulant hirudin in the leech's saliva.
14.
Because of the minuscule amounts of hirudin present in leeches, it is impractical to harvest the substance for widespread medical use.
15.
Scientists have developed anticoagulant medicines from studying substances in the saliva of several hematophagous species, such as leeches ( hirudin ).
16.
The researchers then submitted it to the FDA in making its case to resume the studies with lower doses of heparin and hirudin.
17.
The trials were resumed in May with lower doses of both heparin and the experimental drug, hirudin, with approval from Federal officials.
18.
Recombinant hirudin is available to physicians as an intravenous anticoagulant preparation for injection, particularly useful for patients who are allergic to or cannot tolerate heparin.
19.
It is difficult to extract large amounts of hirudin from natural sources, so a method for producing and purifying this protein using recombinant biotechnology has been developed.
20.
After piercing the skin and injecting anticoagulants ( hirudin ) and anaesthetics, they suck out blood, consuming up to ten times their body weight in a single meal.
