...assimilation studies by James Gozzo, dean of the Bouve College of Pharmacy and Health Sciences at Boston's Northeastern University, as well as by other researchers, including Judith Thomas, director of the Transplant Center at the University of Alabama. They have found that by first transplanting some donor bone marrow into the recipient animal, it is possible to trick the animal's immune system into accepting a solid-organ transplant almost as if it were native to its own body--just as Starzl suggests will be the case in humans. That in turn allows them to use lower doses...
Some 2 million Americans suffer enduring pain caused by rheumatoid arthritis, a condition in which the body's immune system erodes the cartilage and bone near joints. While doctors still do not know why the body turns against itself, they are exploring some promising prospects for relief. One involves mimicking the activity that dampens the immune system in pregnant women, allowing their bodies to adjust to the presence of the foreign fetus. Some doctors believe repeated vaccinations of properly prepared foreign cells will curb the immune reaction enough to hinder the inflammation of arthritis. Other researchers are genetically engineering cells...
...BONE FRACTURES...
Many parents know ultrasound as the device that gives them the first grainy, in-utero glimpse of their baby. Now doctors are using it to speed up bone healing. Even a sonogram's low-intensity waves are enough to stimulate bone-cell formation. When treated within seven days, stress fractures heal as much as 40% faster than they would without treatment. Patients take home a portable device and zap the fracture for about 20 minutes a day until their doctor deems the fracture healed...
...years, results in her body's virtually shutting down production of the hormone estrogen, with attendant hot flashes, irritability and weight gain. Post-menopausal women are also at higher risk for heart disease and osteoporosis (among other things, estrogen prevents the buildup of plaque in blood vessels and protects bone from thinning). On the plus side, the drop in estrogen reduces a woman's risk of developing breast cancer. Estrogen-replacement therapy--whether by pill, skin patch, above, or injection--provides just enough estrogen to prevent the unpleasant symptoms of menopause while offering protection against heart disease and osteoporosis. Before...
