... Duesberg Revisited P. Duesberg is a molecular biologist at the University of California, Berkeley. He contends that the human immunodeficiency virus (HIV) is not the cause of AIDS and is, instead, a harmless "passenger" in the bodies of AIDS victims. Naturally, this stance is controversial, and just as naturally we have had cause to mention Duesberg before. Duesberg is back in the news again because his iconoclastic views were prominently featured in a TV documen tary entitled "The AIDS Catch" seen in Britain in June. The scientific community was furious, claiming that the documentary was one-sided and selective. Further, it was maintained that Duesberg's arguments have been completely refuted. Briefly, Duesberg believes that AIDS is not an infectious disease because: Too few T-lymphocytes in the peripheral blood are infected to cause the disease; HIV carriers without symptoms exist; and HIV in pure form doesn't seem to induce Aids in humans or animals. Rather, says Duesberg, AIDS is a collection of symptoms arising from such factors as the repeated use of intravenous drugs and malnutrition. Mainstream researchers think that Duesberg is wrong on (1 ); that (2 ) is irrevelant, since asymptomatic carriers of typhoid and cholera exist; and that (3 ) may be incorrect, since SIV (Simian Immunodeficiency Virus) does induce simian AIDS in monkeys. (Weiss, Robin A., and Jaffe, Harold W.; "Duesberg, HIV and AIDS," Nature, 345:659, 1990.) Also: Brown, Phyllida; "' ...

... arrangements for the future of her young son and daughter." Instead Anna learned how to "image." She conceived the tumor to be a dragon on her back and her white blood cells as knights attacking the dragon with swords. A year later, the tumor had shrunk. Later, it disappeared complete-ly. Can "imaging" work? Obviously, this is a very controversial question. Admittedly, little real scientific research has been done on imaging per se -- it is a bit too radical a concept. But a few scientists are beginning to chart the chemistry and information flow in the mind-body relationship. For example, the death of a spouse has long been associated with the increased mortality of the surviving spouse. Clinical studies of bereaved spouses reveal fewer circulating lymphocytes, which help the body fight disease, and significantly higher levels of cortisol, a substance that suppresses the immune system's response to disease. Although it is very early in the game, there are verifiable correlations between state-of-mind and body chemistry. Further, other researchers have found that there are sympathetic nerve terminals in such organs as the spleen and lymph nodes, both of which play important parts in defending the body. Imaging just might send the right signals through these terminals, while depression might tend to shut the defense system down. (Hammer, Signe; "The Mind as Healer," Science Digest, 92:47, 1984.) Comment. Imaging is only the latest psychological device humans have tried in fighting disease and promoting health. History is ...

... is through the interaction of the hypothalamus on the pituitary. The pituitary is a source of materials that influence the immune system. Maddox lists several specific candidates, and then observes: "The more radical psychoimmunologists talk as if there is no state of mind which is not faithfully reflected by a state of the immune system." So far, not too radical! But then Maddox comes to an article by J.E . Blalock, University of Texas (Journal of Immunology, 132:1067, 1984.) bearing the title, "The Immune System as a Sensory Organ." Blalock argues that the interaction between the central nervous system and immune system must be reciprocal. By this he means that the immune system's response to infection, through the secretions of disease-fighting lymphocytes, gets back to the central nervous system and produces physiological and even behavioral changes in the infected animal. Applicable studies of animals have been reported recently. For example, rats under stress are found to have less easily stimulated immune systems. (Science, 221:568, 1983.) Also, men who have recently lost their wives to breast cancer have immune systems less responsive to mitogens. (Journal of the American Medical Association, 250:374, 1984.) (Maddox, John; "Psychoimmunology Before Its Time," Nature, 309:400, 1984.) Comment. This is an appropriate time to suggest that "psychoevolution" may be physiologically possible. If the brain can fight disease and even control cell growth, why not a role for the mind in ...
