진행되고 있다. 아직 동물실험 단계에 머물러 있는 암의 면역학적 치료법을 암백신(cancer vaccine)이라 부른다. 암 백신은 기존의 바이러스 백신과 유사하게 특정 암에 대한 항암 면역 반응을 유도, 암을 예방하고 치료하는 것이다.1세기 전부터 시작돼암백신의 연구사는 1세기 전으로 거슬러 올라간다. ...

예방이 가장 중요 하나 난치병일수록 그 원인이 불분명하다. 가장 사망율이 높은 암(cancer)만 해도 아직 예방의 왕도가 없다. 그러므로 질병을 조기에 진단하여 정확한 치료를 행하는 것이 최선이다.의사가 육안으로 관찰할 수 없는 내부 장기에 질병이 의심될 경우 수술 등으로 들여다보는 것이 가장 ...
plastic that surrounds a bomb's aluminum casing is difficult to burn without filling the air with gases that can cause cancer.Recycling valuable parts and metals of bombs is vital in today's world, when the supply of important materials is getting short. One estimate of the value is $11,000 per ton of weapons.At this time, the recycling is going ahead. A weapon's metals are made brittle by ...
PCBs, until they were banned about 20 years ago, were used as coolants. They are thought to cause birth defects and cancer. The truly horrible aspect of PCBs is that they do not go away, for the chemical is stable, continuing to contaminate the planet. Most lakes and rivers are still polluted by PCBs. It was believed a solution had been found by removing sludge and pouring quicklime into it, ...
and there are many false positive and false negative results.Lately one of the better methods of treating ovarian cancer is to give the patient taxol, an anti-cancer drug made from the bark of Pacific yew trees. Taxol is fiercely expensive and very hard to get, for yew trees are few.Since taxol is useful for other tumors as well, the demand has far exceeded the supply. Even thorough testing ...
oil than to risk skin cancer, especially with the hole in the protective ozone layer growing.The latest word on skin cancer comes from Australia. It seems that dogs, cats, even cattle and pigs can also get skin cancer, especially if they are light-colored. Native Australian animals have skin pigment that protects against the sun, but the pets(from European stock) do not, and are vulnerable, ...
It's been discovered that it makes a difference what time of day the patient takes various medicines, especially cancer drugs, some of which can be much more unpleasant, or even lethal, if taken at the wrong time of day. Corticosteroids have fewer side effects when taken in the morning. One dose of antacid at night is worth three during the day.Other living organisms have day-night rhythms. ...
except light. The ultraviolet side of the spectrum of light is invisible to us, even as it gives us sunburns and skin cancer. We also can't see infrared, the 60 percent of light at the other end of the spectrum. The sun, however, emits not only light but X-rays, charged particles and neutrinos.Charged particles zoom out of the sun in what's called the solar wind, reaching Earth in three and a ...
the various changes in the cell cycle are being investigated, and may have important applications in the research of cancer, where cell cycles go away.All natural cell division is possible through the self-replication of nucleic acids in chromosomes. Two years ago, Julius Rebek Jr. and two other organic chemists produced a self-replicating molecule simpler than nucleic acid. It made the news ...
too, in a story I wrote in 1988 entitled "Too Bad," I described a miniaturized robot inside a bloodstream that killed cancer cells without harming normal ones.Perhaps we're on the verge of actually seeing these tiny robots in action!(c) 1990, Los Angeles Times ...
