Despite Baker's apparent fatalism, the U.S. does have another choice. It could back a three-part coalition that includes the two non-Communist factions and the leaders in Phnom Penh but forcefully excludes the Khmer Rouge. Not unless and until the two non-Communist groups accept that realignment should Washington provide them with arms. The result would be a different three- against-one equation that might lead to the eventual disintegration of the Khmer Rouge. And that would be a far happier fact of life for Kampuchea -- as well as a consequence for U.S. policy of which Americans could...
...that careful testing has all but eradicated the AIDS virus from the blood supply, they have not been able to claim that transfusions are perfectly safe. Reason: about 5% of patients who receive transfusions are exposed to a virus that can cause a potentially deadly liver infection called non-A, non-B hepatitis...
...mysterious malady is so named because it is not caused by the widely recognized A and B strains of hepatitis viruses. Symptoms include fever, nausea and fatigue and, in chronic cases, cirrhosis of the liver. About 5% of the U.S. population harbors non-A, non-B viruses. The majority of those who are exposed show no symptoms, but of the patients who come down with chronic liver disease, an estimated 10% die within five years. About 150,000 new infections occur each year because of blood transfusions...
This last major threat in the U.S. blood supply may soon be greatly reduced. After six years of research, scientists at Chiron, a genetic-engineering firm in Emeryville, Calif., have developed a test for the presence of a non-A, non- B hepatitis virus in blood samples. According to papers published last week in the journal Science, trials have shown that Chiron's test is highly reliable. It can now help eliminate the virus from the blood supply. The inexpensive test (about $2 per blood sample) is expected to be approved by the Food and Drug Administration this year...
Chiron's initial breakthrough was to isolate a viral protein from blood samples taken from patients with non-A, non-B hepatitis. By cloning large quantities of the protein, the company was able to develop a test to detect its presence in blood. Chiron called the pathogen the "hepatitis-C virus." In clinical studies done at the National Institutes of Health, the Centers for Disease Control and laboratories in Italy and Japan, blood samples from patients thought to have non-A, non-B hepatitis were screened using Chiron's test. At least 80% of the samples tested positive...
