Their use has been revived in hospitals in Britain, the USA and elsewhere, to 
drain venous blood from transplants and from varicose veins. Also, their 
saliva, which contains an anti-coagulant, is being used in drugs that prevent 
clotting. The most widely-employed, hirudin, is mainly produced by 
recombinant technology using either the bacterium Escherichia coli or yeast 
cultures. One of the alternatives to hirudin is ancrod, which is derived
from pit viper venom.

Regards,
 
Roger
