...speculation went on, researchers in U.S. labs added their own clues: the blood of AIDS victims has an imbalance among the cells that help govern the production of antibodies. A normal immune system has twice as many helper Tcells, which stimulate the making of antibodies, as it does suppressor Tcells, which keep antibody production under control. In an AIDS victim, the ratio may be reversed. Often there are fewer cells of both types...
...AIDS victims is simply overpowered by the assault of a variety of infections. Both drug users and active homosexuals are continually bombarded by a gallery of illnesses. Repeated exposure to the herpes virus, or to sperm entering the blood after anal intercourse, can lead to elevated levels of suppressor Tcells. The immune system eventually is so badly altered that, as one researcher puts it, "the whole thing explodes." Other experts combine the two theories, speculating that a new virus may indeed be involved, but that it only takes hold when a combination of factors affects the potential victim, such...
...thymus, which plays a role in their development). Certain of these cells help defend the body against viruses, foreign tissue (like organ transplants) and the growth of cancer cells. There are several types, including helper T cells, which promote the production of antibodies against foreign invaders, and suppressor T cells, which reduce antibody output. Healthy individuals have twice as many helpers as suppressors. In AIDS victims, the ratio is reversed; helper cells are depleted. No one knows what happens to these cells, but New York Immunologist Roger Enlow has a theory: "Just as hepatitis B virus preferentially attacks liver cells...
...Edward T. Tyler, 62, gynecological researcher whose work helped to develop the Pill; of a heart attack; in Los Angeles. As medical director of the Los Angeles Planned Parenthood center, Tyler ran many early studies of oral contraceptives, and investigated such variants as antipregnancy "vaccines" and a male sperm suppressor. He also tested the fertility drugs that have sharply reduced sterility and made multiple pregnancies common...
With each sortie, too, goes an "Iron Handle" of four suppressor planes-one a pathfinder able to finger SAM radar signals, the three others armed with rockets, notably the 10-ft. Shrike, which homes in on radar radiations. Last week Iron Handle flights hit ten SAM installations out of the total estimated 100 sites in North Viet Nam. Though the SAMs have had little direct success-bringing down 14 U.S. planes out of 296 launchings in the year since the first was fired -they do aid the enemy in another respect. Because SAMs are most effective at high altitudes, they...
