Preventive veterinary medicine is burgeoning. Animal doctors now routinely use X rays and other imaging techniques to detect nearly invisible hairline cracks in horses' legs before fractures occur. For tendon and ligament injuries, says University of Pennsylvania Veterinarian Virginia Reef, "diagnostic ultrasound has been a big boon in racing and horse-show circles." Racing has become such big business that young horses increasingly compete regularly when they are only two years old, before their bodies are fully mature. Equine Specialist Howard Seeherman of Tufts uses the treadmill % to condition yearlings in order to reduce injuries and improve performance. Says...
Other scientists are seeking a better understanding of why the ceramics become superconductors. Many labs have taken pictures of the materials with electron microscopes, pulsed beams of neutrons, X rays and ultrasound. A team of Bell Labs and Arizona State scientists has produced electron-microscope photographs that show defects in the compound's crystalline structure. Says Team Leader Abbas Ourmazd: "We don't quite understand what role the defects play, but it raises some provocative questions. Is it the perfect material that is superconducting? Or is it the defects? If it turns out that it is the defects, then...
...monitoring procedure consists of measuring levels of the hormone estrogen in a patient's blood or urine. As the follicles mature, hormone levels gradually increase. The higher the estrogen level, the likelier it becomes that more than one egg has matured. Another procedure is the sonar-scanning technique called ultrasound, which produces black-and-white images of a woman's ovaries upon which the number of ripening eggs can be counted. Multiple pregnancies can usually be avoided by using one or both methods. In spite of their ordeal, the Frustacis have faith in drugs like Pergonal. Said Patti: "I want...
Patti Frustaci, a high school English teacher, added 70 lbs. to her 115-lb. frame while carrying the septuplets. Surprised by her large size early in her pregnancy, doctors scheduled an ultrasound examination that detected three fetuses. A later sonogram revealed seven babies in her womb. The Frustacis were dazed. Recalled Sam: "I said to Patti, 'Dogs have litters...
...winter. In January, 70,000 antiabortion demonstrators took part in a March for Life in Washington, as they have done on each anniversary of Roe vs. Wade, and were addressed by Reagan. His message: "These days, as never before, the momentum is with us." A graphic film that shows ultrasound images of a fetus being aborted, The Silent Scream, has received wide play and inflamed antiabortion passions, even though a number of medical authorities have denounced it as a distortion. "We are responding to what the pro-lifers have done," says Lauren Virshup, executive director of the California branch...
