Passage 1 Surgeons can perform phenomenal feats. They replace clogged coronary arteries with blood vessels from the leg. They reconnect capillaries, tendons, and nerves to reattach severed fingers. They even refashion parts of intestines to create new bladders. But surgeons find it difficult to reconstruct complicated bones like the jawbone or those of the inner ear. And only rarely can they replace large bones lost to disease or injury. The challenge stems from the nature of bones. Unlike other types of tissue, bones with one normal shape cannot be reworked into other shapes. Nor can doctors move large bones from one part of the body to another without severely disabling a person. Existing treatments for bone defects are all short-term and limited. Surgeons can replace some diseased joints with plastic or metal implants, but artificial hips or knees steadily loosen and must be reconstructed every few years. Fortunately, surgeons are beginning to overcome these obstacles by creating bone substitutes from, of all things, muscle. The idea of making bones from muscle is not all that strange. Muscle, bone, fat, blood vessels, and bone marrow all develop in human embryos from the same loosely organized tissue. In 1987 scientists isolated a bone-inducing protein called osteogenin from cows. Osteogenin can make undifferentiated human tissue produce cartilage and bone. But few surgeons have used osteogenin because it is hard to control. If sprinkled directly onto a defect, for instance, the entire area might stiffen to bone if a tiny bit fell on surrounding blood vessels and nerves. More recently, plastic surgeons have circum-vented that snag by prefabricating bones away from the immediate site of a defect. Flaps of animal thigh Line (5) (10) (15) (20) (25) (30) (35) For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org muscles are taken and placed in osteogenin-coated silicone rubber molds of the desired shape. The molds are implanted in the same animal’s abdomen to provide a suitable biologic environment for (40) transforming muscle into bone. Within weeks, the molds yield tiny, perfectly detailed bone segments. So far, surgeons have made bones from muscles in small animals, but have not yet tried the process in humans. For one thing, osteogenin is available only (45) in small amounts. Secondly, the safety and effectiveness of the process must first be tested on larger animals. Passage 2 We have entered a new era in medicine. In scarcely more than a generation, artificial organs (50) have evolved from temporary substitutes to long- functioning devices. Millions of people live with cardiac pacemakers, arterial grafts, hip-joint prostheses, middle-ear implants, and intraocular lenses. Eventually, artificial organs will allow (55) ordinary, healthy people to live longer – or, more appropriately, to die young at a ripe age. So far, though, even the best substitutes lag far behind their natural counterparts. But the obstacles to better implants are not purely technical. Because such (60) devices require human testing, their development poses a challenge to our cultural and ethical values. Although many patients volunteer for tests of unproven medical devices, such altruism – and the medical progress it engenders – is hampered by (65) medical ethicists and others who call for more restrictions on human testing. While people favoring restrictions are well-intentioned, their standards are inappropriate. The only way to gain the information needed for (70) refining artificial organs is through experiments on people. Research using animals will not suffice. The mechanics of bone joints, for example, differs markedly from species to species. The replacement of wrists, knees, and finger joints poses complex (75) engineering problems because of the heavy mechanical loads involved and the range of motion required.
