...part in Bass's experiment. When they started, some of them found breathing so difficult that all physical activity was an arduous chore. But during the gradual exercise buildup, they all showed improvement. Their hearts now function more efficiently. Work has become easier, and their bodies require less oxygen for a given task, presumably because their lung tissue has been stimulated to greater efficiency. Bass does not recommend his treatment for all of the 400,000 Americans troubled by emphysema, many of whom have other serious disorders. His patients, however, have no such compunctions. Like 74-year-old Dudley...
...pair of treelike bony structures located above each gill cavity, the organs absorb oxygen from the air to supplement the oxygen normally taken in from water passing through the gills...
...Death," Hudson said, "is a gradual process at the cellular level, with tissues varying in their ability to withstand deprivation of oxygen. Medical interest, however, lies not in the preservation of isolated cells but in the fate of a person. Here the point of death is not so important as the certainty that the process has become irreversible...
...After the incisions were made, the real technical difficulties began. Moore and his chief assistant, Dr. Alan Birtch, clamped off the portal vein, which delivers blood to the liver for chemical processing, and the inferior vena cava. The hepatic artery, which delivers blood for the liver's own oxygen needs, was so damaged by pressure from the cancer as to be useless. Moore and Birtch decided to use in its place the right kidney artery. That meant removing the right kidney, but a single healthy kidney is all the body needs...
...P.H.S. did not limit its concern to lung cancer, but pointed to an "increasing convergence" of new evidence that smoking can contribute to the development of heart disease. It does this, according to latest research, by producing a gap between the heart's demand for oxygen and the blood's ability to supply...
