...Parkinson's victims, most of whom are middle-aged or elderly, integrate with fetal tissue? Could a virus that found its way into the brain, which is normally unaffected by the immune system, accidentally set off an abnormal immune response that would destroy the graft? And even without viral intervention, would the foreign fetal cells be rejected? Moreover, surgeons will have to know precisely how much tissue from what stage of development should be used in each transplant. Taking the tissue too early, for example, might result in runaway cell growth that could wreak havoc in the brain...
Last year a viral infection stayed Steffi from Wimbledon, and while nobody concedes her a pre-eminent place yet on grass (she's seeded second), everyone seems sure the true heir to Evert-Navratilova has been found. And glamorous Argentine Gabriela Sabatini, 17, may be her baseliner-in-waiting. They are doubles partners and friends but could start a Centre Court rivalry next week in the quarterfinals. Evert says, "I can't believe how hard Steffi hits the ball." Her forehand especially. "She's wonderful," says Billie Jean King, who spotted Graf early. "Steffi always had better footwork than...
There has also been little progress in developing AIDS drugs that interfere with viral reproduction. The only drug approved by the FDA is azidothymidine, or AZT. An experimental drug, ribavirin, made by ICN Pharmaceuticals of Costa Mesa, Calif., seems to be less effective than had been claimed. Dr. Andrew , Vernon, a member of a study group at Johns Hopkins University, reported that in a 28-week experiment, 217 male pre-AIDS patients who took ribavirin showed no significant benefits...
...Africa to the U.S., and why it only strikes staff and patients at clinics with prepaid health-care plans. Physician-Novelist Cook enjoys stretching credulity (in his previous blockbuster Coma, people were murdered to provide organs for the transplant trade). Here a league of conservative doctors plays with the viral equivalent of nuclear weapons in order to preserve its market share. The petit Dr. Blumenthal discovers the Hippocratic hypocrisy only after she is turned into a composite of Nancy Drew and Wonder Woman, crisscrossing the country to study and contain flare-ups of EHF. Cook's best-selling technique...
Active bisexuals are one route of viral transmission to the female population. In 1984 Free-Lance Writer Alexandra Wolf, 41, met a charming man in Hollywood. "We hit it off really well," she recalls, deciding at the time not to use any sexual precautions because "it's not a risk-free world, and I'm going to take the chance." After four encounters, he confessed he was a bisexual whose previous lover had died from an AIDS-related cancer. Ten months later, tests confirmed that Wolf had the live virus in her bloodstream...
