Artificial Blood

November 30, 1985 | HARRY NELSON, Times Medical Writer
Artificial red blood cells made from outdated human blood have been shown to be safe and effective when used as oxygen carriers in animals, according to researchers at the University of California, San Francisco. The artificial cells meet all the requirements of a blood substitute, study leader C. Anthony Hunt said. The substitute could be stored longer than whole blood, could be given to people of any blood type and has potential uses in surgery and trauma care for both humans and animals.

The Food and Drug Administration, concerned about disappointing results with the Jarvik-7 artificial heart, said today that it is considering whether to allow Dr. William DeVries to complete a series of seven implants the agency earlier authorized. DeVries, based at the Humana Heart Institute of Louisville, Ky., is the only U.S. surgeon licensed to implant permanent artificial blood pumps in humans.

Vladimir Apekin's wife and daughter are engaging in an indefinite hunger strike in the hope that they can persuade the Soviet authorities to let the refusenik leave the country for special medical care. Apekin, 49, a former marine biologist who was dismissed from his job after he applied to emigrate to Israel, was hospitalized in early March for a variety of ailments, including heart disease.

The Cray-2 is only four feet high and four feet in diameter, but the new $17-million device at NASA's Ames Research Center is the world's fastest, most powerful supercomputer. Because its micro-miniaturized electronic circuits are packed so close together, the compact machine is the first supercomputer to have components immersed in a colorless fluorocarbon liquid that prevents overheating. The liquid also often is used as artificial human blood plasma.

Heart bypass patients may soon be able to get new arteries without having to sacrifice vessels from other parts of their body, thanks to ready-made, off-the-shelf artificial blood vessels. Biomedical engineers have been trying to build replacement blood vessels, needed for coronary artery bypass surgery and kidney dialysis patients, for three decades. Researchers from Humacyte Inc., in Durham, N.C., discovered the trick: recruiting cells to build the vessel, then washing them away so the nonliving tissue is storable and works for anyone.
Ten years ago, Dr. Robert Ferguson conducted an improbable experiment. Using balloon angioplasty, a technique to unclog coronary arteries, he tried to open a blocked artery in a stroke victim's neck. The patient thrived, but Ferguson, a radiologist at Baptist Memorial Hospital in Memphis, was practically run out of medicine for taking the therapeutic gamble, which he believed was justified because the patient also had cancer, making him ineligible for standard surgical therapy. "There was great doubt that this made any sense," Ferguson said.
A year ago, the Navy gave Anthony Mulligan's company a small grant to build a cheap aerial drone for whale watching. The idea was to make sure marine mammals weren't around during sonar tests. Then came Sept. 11. And, with the help of an Arizona congressman, Mulligan transformed the drone into a potential weapon in the new war on terrorism.

In the 1950s and 1960s, surgeons devised operations that revolutionized the treatment of peripheral vascular disease, a condition in which the arteries in the pelvis and legs are narrowed by a buildup of cholesterol and calcium clots in the vessel. The new advance was to install artificial blood vessels made of Dacron or to use one of the patient's veins to bypass the clots. These procedures prevented amputations and improved the lives of thousands of patients.
