Spun in a centrifuge, it divides into layers-red cells on the bottom, a thin intermediary layer of platelets and white cells, and an upper tea-colored layer of plasma. Each layer, in turn, can be used as various therapeutic products. Red cells can be transfused directly. White cells and platelets can be used to restore resistance or clotting ability to patients undergoing chemotherapy. Plasma, a resource in its own right, yields albumin for restoring circulation, clotting factors for patients with hemophilia, antibodies for vaccine production, and several other reagents and pharmaceuticals. Taken as a whole, the value of the derivatives in a forty-two-gallon barrel of crude oil would raise its price. The price of the same quantity of completely processed blood would increase its value to more than 67,000.

Why review those scandals essay erupted is one of the underlying questions of this book, a history of human blood as a resource and humanity's attempts to understand and exploit. Blood is one of the world's most vital medical commodities: The liquid and its derivatives save millions of lives every year. Yet blood is a complex resource not completely understood, easily contaminated, and bearing more than its share of cultural baggage. Indeed, the mythic and moral symbolism of blood, which has been with us since ancient times, subtly endures. It clouded professional judgments and public perceptions in the aids scandals of France, canada, and Japan, among others. If one considers blood a natural resource, then it must certainly rank among the world's most precious liquids. A barrel of crude oil, for example, sells for about 13 at this writing. The same quantity of whole blood, in its "crude" state, would sell for more than 20,000. Crude oil, as we know, can be broken down into several derivatives, including gasoline, distillates such as diesel, and petrochemicals. Blood can be separated into derivatives as well.

To them the affair was a matter of betrayal. The doctors on trial in the summer of 1992 were supposed to have embodied all that was noble in the French transfusion tradition-altruism, medicine, business, and technology. Instead, during the years of the "contaminated-blood affair" they came to symbolize the cynicism and expediency of a money-driven age. The sense of betrayal surfaced in many places beyond the courtroom in Paris. For more than a decade the theme has been sounded in one locale after another throughout the world. In America, patients have filed hundreds of civil suits against doctors, drug companies, and even their own patient organizations, for abandoning their health to the expediency of the marketplace. In England, aids-infected hemophilia patients castigated their national transfusion service with reacting too slowly to the threat of emerging viruses. In Japan, patients charged that the government and drug companies criminally concealed the contamination of blood products; as a result, some of the nation's most revered doctors have gone to jail. In Canada, the scandal of contamination spread so wide that the government held a series writings of hearings across the country that convulsed the nation with anger and shame.

In keeping with the real formality of French courts, the prosecuting and defense attorneys wore flowing black robes, which would dramatically sweep behind them as they rose to make a point. The only visible flaw in the decorum appeared among the audience members, some of whom wore t-shirts bearing inflammatory slogans. There were audible exceptions to decorum as well, as people would moan or shout "Non!" at a defendant's response, or when one man, the most vocal of the plaintiffs, would, as his doctor walked past, loudly hiss "Assassin!". The plaintiffs in this trial were dying of aids. They charged that they had been infected through the negligence of the defendants-high officials in the French national transfusion service. In France, where the government until recently held a monopoly on blood and its derivatives, these men were supposed to ensure the safety of blood products. Instead, they allowed thousands of the nation's hemophiliacs to inject blood-derived clotting factors they knew to be contaminated. The defendants had done so because of a complicated mixture of paternalism, economics, and to some extent the limits of science, but the victims saw the incident more starkly.

Hiv is primarily a sexually transmitted disease, it is transmitted by both homosexual and bisexual and heterosexual activity. The first recognized case was among homosexual and bisexual men. Many numbers of studies have shown that men who have sexual partners and those who practice receptive anal intercourse are more likely to be infected with hiv than other homosexual men.

The health of the general homosexual populations in the area with the largest number of cases of the new disease was getting looked at a lot closer by researchers. For many years physicians knew that homosexual men who reported large numbers of sexual partners had more episodes of venereal diseases and were at higher risk of hepatitis b virus infection than the rest of the population, but coincidentally with the appearance of aids.

Other debilitating problems began to do appear more frequently. The most common was swollen glands, often accompanied by extreme fatigue, weight loss, fever, chronic diarrhea, decreased levels of blood platelets and fungal infections in the mouth. This condition was labeled arc (aids related complex). The isolation of hiv in 19the development of techniques to produce large quantities of the virus paved the way for a battery of tests to determined the relationship between aids and arc and the magnitude of the carrier problem. Using several different laboratory tests, scientists looked for antibodies against the hiv in the blood of aids and arc patients. They found that almost 100 percent of those with aids or arc had the antibodies-they were seriopostive. In contrast less then one percent of persons with no known risk factors were seriopostive. Aids is defined as a disease, at least moderately predictive of defects in cell- meditated immunity, occurring in a person with no known cause for diminished resistance to that disease.
