[Marxism] Why They Hate Us...

Beware of dismissing traditional techniques and forms of medicine as
"backward" simply because of the cultural milieu: the use of medicinal
leeches for bleeding has been revived as a legitimate form of treatment for
certain conditions. For example, according to one article
"In the 1980s leeches "crawled out of their therapeutic closet" when
plastic surgeons found its local anticoagulant and bloodletting properties
useful for relieving venous congestion in grafts and transplants.(5)
Failure of adequate venous return from a graft reduces blood supply,
causing tissue necrosis. Placing a leech on the congested skin flap,
finger, or other compromised area removes the congested blood and enables
the graft to be salvaged. Leeches are currently used during postoperative
care of reimplanted fingers, skin grafts, and breast reconstructions.
Pharmacological interest in the leech began when hirudin, an anticoagulant,
was identified in the saliva of leeches in 1884. Hirudin was used in early
transfusion experiments 30 years before heparin was used. Since 1986, when
hirudin was genetically engineered, interest has been revived in the drug
as a systemic anticoagulant free of some of heparin's side effects.(10) The
salivary glands of leeches also produce a cornucopia of other
pharmacologically active substances, including an antihistamine, proteases,
and, possibly, an anaesthetic and an antibiotic.(5)
As the benefits of judicious treatment with leeches are recognised, the
range of conditions that can be treated extends. There are case reports of
effective leech treatment for haematomas,(11) purpura fulminans,(12)
paronychia,(13) and even vascular congestion of the penis.(14) And leech
saliva may provide a host of new drugs. If we have learnt any lesson from
the past it is that controlled trials are essential, but leeches are
probably back in the formulary to stay."
