...operations were needed because massive radiation destroys vulnerable bone-marrow tissue. The vital substance acts as the body's production center for blood cells that carry oxygen, help to cause clotting and provide immunity against disease. Victims of damaged marrow can die within weeks of severe anemia, hemorrhaging and infection. To transplant the tissue, physicians use a syringe to draw out healthy marrow--usually from a donor's hipbone--and inject it into the patient's bloodstream. The marrow cells make their way naturally to the interior regions of bones. For the procedure to succeed, the tissue of the donor...
...crusade. In 1983, for example, he talked two Nobel laureates and other scientists into signing a declaration urging Congress to ban any genetic engineering of human sperm and egg cells, despite the fact that such a ban would halt research aimed at eliminating genetic diseases like sickle- cell anemia and Down's syndrome...
During the five years following the first student protests, Harvard tenured four Black faculty members--in the last 10 years, it has added only two. Furthermore, 15 years after its violent birth, the Afro-American Studies Department continues as an impoverished ghetto, lacking crucial resources and faculty. Its current anemia is less the product of feeble inception than malnourished neglect...
...Lesch-Nyhan syndrome; adenosine deaminase deficiency, an immune disorder of the type that killed the famous "Bubble Boy"; and purine nucleoside phosphorylase deficiency, another illness of the immune system. As investigators learn ever more about gene regulation, however, they may tackle ever more complicated hereditary diseases, including sickle-cell anemia, diabetes and even cancer. Meanwhile, the increasing genetic adeptness of researchers worries some observers, who fear the application of recombinant DNA to human beings. Some extreme critics even evoke visions of Hitlerian attempts to engineer a new master race. Most scientists dismiss these fears, pointing out that the new therapy...
...four experienced impairment of their immune systems in the weeks following surgery, and all suffered from some form of infection, ranging from urinary-tract problems to pneumonia. Experience with the four patients has also shown that the artificial heart batters the red blood cells, causing a form of anemia. As a result, said DeVries, "if you have an artificial heart, you can expect to have blood transfusions once or twice a month...
