Duchenne Muscular Dystrophy Essay -- Muscle Disorder Psuedohypertrophi

Duchennes brawny dystrophy, also known as psuedohypertrophic knock-down(a) dystrophy, is a typical sex-linked disturb in which the muscles degenerate without a persons life. It literally nub faulty nutrition of the muscles. Muscular Dystrophy has no cures, and this particular display case of unchewable dystrophy affects only males. One in 3,500 baby boys ar born with this disorder and survival is rare beyond the early 30s, stopping point is usually caused by a respiratory disease. (ygyh.org)Duchennes muscular dystrophy is named afterwards the French neurologist, Guillaume B. A. Duchenne, who lived from 1806 to 1875. In 1861 he became the first person to describe the disorder. In 1951 Elizabeth Shull Russell, an American inheritedist, accidentally observed Duchennes muscular dystrophy in a colony of mice with which she was working. Over a number of years she discovered that muscular dystrophy was a sex linked trait contained on the x-chromosome. (Narins, 798.)s ex-linked disorders only affect males and are passed down through female carriers. A boy inherits the disorder when he receives an X chromosome with a mutated dystrophin gene (the genetic cause) from his mother. The dystrophin gene is the largest gene found in nature and was identified through a positional cloning approach. Its a highly complex gene, a large rod-like cytoskeletal protein which is found at the inner surface of muscle fibers. (www.ncbi.nlm.nih.gov) leash different tests are used to determine if a male has Duchennes muscular dystrophy. A CPK (also known as a CK) assay will let on muscle damage, but not the source. CPK is an abbreviation for Creatine Kinase Assay, which is essentially a blood test. Muscle biopsies are also common, a needle is inserted... ...nerated and replaced by fat. Recently, specific compounds in the oil have been identified, they produce regeneration that is evening more amazing than that produced by the oil itself. (Gerras, 1056)This fo rm of MD is normally appears in males, but there are a few passing rare cases where it has appeared in females. Most of the statistics found only dealt with Duchenne muscular dystrophy in the U.S., so it is assumed that the disorder is more prominent in the United States. Also, there was no evidence that it affected any flight more than another. (www.ygyh.org)Concluding, Duchenne?s muscular dystrophy is an excellent example of a sex-linked disease. Unfortunately, there is no cure but research is world used to find more effective treatments. Most deaths caused by the disorder aren?t directly due to the muscles, but due to a respiratory disease or disorder.
