Method of diagnosing BSE by urination

Introduction: experts from hadassar Medical College in Israel announced Tuesday that they have developed a method to diagnose mad cow disease and related new human Creutzfeldt Jakob disease with urine sample test The invention will provide a new way to detect and control the spread of BSE, and provide convenient and cheap countermeasures to control the spread of BSE among humans The cause of spongiform encephalopathy such as BSE is variant prion protein Up to now, the protein in the brain of cattle and human can not be reliably detected in the blood samples of the diseased organism, so it is very difficult to diagnose However, using the method of experts from hadassa Medical College, people can easily detect a special protease structure in urine samples, so as to infer the existence of prion protein What's more, this test can confirm whether the organism is infected with the disease long before symptoms appear The research results of experts in neuroscience of hadassa medical college were published in the Journal of biochemistry in June Experts from hadassa Medical College believe that according to common sense, most of the protein will be broken down in the kidney and will not enter the urine, which is an important reason why people did not invent the mad cow urine test before But in fact, there are still traces of the variant prion protein in the urine of organisms, so they invented the new method It is reported that the medical school recently carried out a successful test: 50 urine samples of cattle infected with BSE were sent from the UK, mixed with healthy urine samples of cattle, and all 50 samples were detected without knowing the exact number of sick cattle samples This convenient and cheap urine test method will bring good news to the animal husbandry affected by mad cow disease In the past, once a case of BSE was found in an area, all cattle in this area were often killed to avoid the spread of the disease due to the lack of simple and reliable detection methods But now, there is no need to kill a large number of healthy cattle through urine sample testing, avoiding the huge economic loss of animal husbandry In addition, in the past, people in the epidemic area of mad cow disease were banned from donating blood due to the fear that there had been variant prion protein in the blood Now, the urine sample test method can easily return the clean to the healthy epidemic area population, and is conducive to the early warning of patients However, experts from hadassa Medical College point out that the presence of variant prion protein in urine will cause people to be alert to the spread of BSE through urine.
