oxygen from the lungs to the tissues. People
lost a lot of blood, make blood transfusion to increase
oxygen supply.



Hemoglobins of animal origin may cause allergic reactions and even
kidney damage. But it turned out that the hemoglobin conventional marine worm
lobworm (Arenicola marina) does not lead to such consequences, at least in
mice. "Preclinical data are staggering - says biologist Frank Hall of Paris
University of Pierre and Marie Curie. - We do not need to modify only
recasit and clean ".



"The large size and nature of the molecule makes it an ideal" - said Rhoda
Alison Hirsch, which explores the stascture and dynamics of hemoglobin in the medical
Albert Einstein College in New York.



Being about 50 times larger than a molecule of human hemoglobin, a protein
worm can damage the kidneys. If human hemoglobin is transfused without
protection of red blood cells, it breaks into small fragments that
clog the filtration system of the kidneys.



Scientists have yet to verify whether to remove the free hemoglobin worm oxide
nitrogen from the walls of blood vessels, increasing blood pressure. In human blood
hemoglobin inside the red blood cells. Research Groups
try to simulate this by placing a molecule into an artificial cell, or
modifying their stascture.



Pharmaceutical company engaged in the development of blood substitutes over 30 years.
The best hope inspire synthetic extracts from human or bovine
hemoglobin. Although these dasgs have not received the approval of the American Management
The Food and Dasg Administration, one of them applies in South Africa.
