a new student aid: plastic body parts, made from the real things
Mary ROACHMARCH army, 2000 dead in Detroit, unclaimed body, funny things happen. The body could eventually be donated to the plaster lab at the University of Michigan Medical School and become timeless -- Ready version of itself. Paste is the process of taking organic tissue --- Like a Rose bud, or a person\'s head. - Replace the water with a liquid silicone polymer. After the application of the catalyst, the polymer becomes hard and the body of the deceased is permanently preserved. So far, relatively small-scale plasters have been carried out on the body parts and organs and then sold to universities and medical schools for anatomy courses. But last month, in North America, the whole body was plastered for the first time. The project was conducted at the University of Michigan\'s plaster laboratory, which was opened in 1989 and managed by a PhD. Associate Professor of Anatomy, Roy Glover Advertisementastation originated in 1981 by Dr. GUNT von Hagens, German chemist When his patent expired, Dow Corning revised the process to make it cheaper and faster. Dr. advertising Glover says he can put plasters on the heart within 24 hours, but it will take a week for von Hagens\'s approach. Dr. Von Hagens is in the sub- Freezing conditions to prevent premature hardening of the catalyst; Dow Corning came up with a way to add a catalyst after the main body is soaked with a polymer, so the whole process can be done at room temperature. As a teaching aid, plaster organs have advantages over models and organs preserved in formaldehyde by traditional methods. Formaldehyde is an unpleasant toxic substance. - So much so that federal authorities regulate its use in laboratories --- When removed from the liquid, the organs deteriorate rapidly. The organs affixed with plasters are non-toxic, very durable, dry to touch and have no smell. They can be written on it and can be customized if the customer wants Highlight specific structures. In Grand Rapids, Michigan, Carl College participated in the communication barrier program. , Dr. Glover creates a head and neck bisector with plaster applied, providing a profile view of the human vocal device. While plastic models of this structure exist, they often distort the size and position of the part for clarity. \"The students were surprised to see what was real,\" said the doctor. Judith van der Ward, an assistant professor at the college. \"This is absolutely great. \"At the University of Michigan Medical School, the dispensing organs are used together with the\" virtual anatomy \"computer program. \"Actually, you can hold the sample in your hands and study computer programs at the same time,\" Dr. Glover said. This is a powerful learning tool. \"Despite the advantages of advertising, in the general anatomy laboratory of the medical school, the entire body with plaster is unlikely to replace the entire body with anti-corrosion. \"In general anatomy, the plaster part is useful for showing the details,\" the doctor said . \" Arlen Severson, department head of Anatomy and Cell Biology, Duluth School of Medicine, University of Minnesota. \"But plastic makes the body too stiff. This makes anatomy impossible for medical students. It also hinders big costs -- Scale plasticization--Dr. Glover Labs charges $13,000 for handling a body. - Shortage of facilities and qualified plasters. There are 50 to 80 around the world. \"Now, all the people who can do this are teaching professors,\" said Dan Corcoran, chairman of the Corcoran laboratory in the Gulf city of Michigan. A company that supplies plaster chemicals and equipment. \"They don\'t have time. \"Please click on the box to verify that you are not a robot. The email address is invalid. Please re-enter.

Mr. Corcoran estimates that 157,000 to 100 of the world\'s 200 medical schools may be using body parts with plasters. Complete body of doctor Today Glover\'s lab is not for medical school. They will become the main attraction of the Museum of tourism anatomy, developed by the doctorGlover and Mr. Corcoran with the help of Dow Corning Starting this summer, the exhibition will be visited at natural history museums and universities across the country. Recently, Dr. Glover showed a visitor the fourth complete human body in progress in his lab. On the back of it is a stainless steel acetone tank filled with a strong smell of nails -- Every time a doctor goes to Poland to remove makeup Glover opened the lid. Acetone drains water from body tissue to prepare for dipping with silicone polymer. The man in acetone died in his 60 s. He has a moustache and a tattoo that will both survive the plastering process. ( There are plasters on the skin and any other organ. ) Each body of the museum will be used to highlight different biological systems or a set of systems: Digestive system, nervous system, cardiovascular system Breathing, reproduction, and muscle bones. The bodies will look like they did on the day of their death, with slight cosmetic enhancements. Discoloration of muscles and skin can be modified with dyes and colored polymers can be injected into the vein. On some bodies. Glover plans to remove the chest wall and reconnect it with a hinge so it opens like a refrigerator door to reveal the organs inside. The bodies of both men and women are in preparation and will not make any changes in the name of modesty. From the acetone bath, the body is transferred to the whole Body plaster room, cylindrical stainless steel tank full of liquid polymer. The vacuum attached to the tank reduces the internal pressure, turns acetone into a gas and pulls it out of the tank. When acetone is extracted from the tissue, the silicone polymer is pumped out to replace it. Dr. advertising Glover handed a flashlight to his visitor to see the view through a portico window at the top of the room. When the acetone gas stops bubbling- Usually two weeks later. - Remove the body from the chamber. The rest is to pose the body, set the polymer with the catalyst, and install the finished sample on the display stand. Dr. Glover uses Mr. plant to apply the catalyst, which begins a chain reaction, which is carried out throughout the body to Harden to a firm but sliding consistency. The body of the Anatomy Museum is an unclaimed deceased and has no known close relatives. Dr. Glover does not use the bodies of those who choose to donate their remains to science, as these families often want the ashes of the deceased ( Mainly from bones) In this case, he will not be able to help. However, the donated body was used to apply medicine to organs and body parts. Provide a form to potential donors that allows them to authorize or prohibit the university\'s various scientific uses of human remains, including plasters. ( The checklist uses the word \"permanent save. \'\') The commercial potential of Plast is considerable. It can replace the specimens of the Natural History Museum. If you carefully wipe the fur with acetone after applying it, it will remain soft and soft. It also stays on the specimen for a longer time than on the specimen, because the plaster process locks it in the skin. The only thing that hinders the commercial plastic placement of museum specimens is, again, the lack of facilities and personnel to carry out this procedure. \"If we had tanks big enough, we might have made elephants or whales,\" Mr. Corcoran said. Mr. Corcoran suspects that some enterprising morgue scientists will build a factory one day. The institution of the scale plastics fund. ( Think what Lenin\'s plasticization can do. )The way Mr. Corcoran saw that the demand was already there. \"There was a gentleman doing mummies somewhere,\" he said . \". \"He does it once a week, $60,000 for a body. He has a backlog. There are enough odd people in the world, and someone will do a good job. \"It may be sir. Corcoran himself. \"If the museum doesn\'t take off, maybe I\'ll build some tanks and do that. \'\' he said. As far as he is concerned, doctor. Glover is not interested in the non-educational aspect of paste. He politely refused the request of a woman who wanted her dead Yorkshire terrier to be plastered. \"We don\'t do that kind of private thing,\" he said \". However, he made an exception for science students. There was a note to himself on the whiteboard in his office: \"Maria Lopez --- Daughter\'s brain-science fair. \"We are constantly improving the quality of text archives.
