Sampling convenient, without the risk of infection --
According to "The New York Times" reported that the University of California, Los Angeles research group took three years, costing 57 million U.S. dollars has finally opened a secret saliva. In the near future, saliva will completely replace the post-mortem blood test. Since then, we can not extend the arm Ziyaliezui the relentless扎to doctors to be aware of the health status of the body. And the saliva test more secure, without fear of cross-infection.
Saliva diagnostic blood test and can replace the urine test.
If you know nothing about the role of saliva magic, then this "post-mortem saliva" may be your斥为fantasy. In particular, saliva has been都难Deng Dayazhitang. However, unlike the rest of us, the University of California, Los Angeles branch of the dental Professor Wang Dawei about his beloved one of the saliva on the talking.
He likes talking about the composition of saliva, color, smell and its sociology, feel that these are extremely sophisticated. He spent several hours with the exchange, you will know that saliva is an excellent lubricant, so that food can be smoothly swallowing so that the words become fluent. If there is no saliva, human beings simply can not eat, swallow, the sound hoarse.
According to "The New York Times" reported that, 50-year-old Dr. Wang, the University of California, Los Angeles is the Faculty of Dentistry, vice president of research affairs. From his remarks can be seen in this particular novel idea is that he can see the future of saliva.
In his laboratory, Dr. Wang has been studying the molecular structure saliva, hope to develop a set of new testing methods as a means of diagnosis of human diseases. He predicted there will be a lot of saliva function, and hope to use a new technology to replace the saliva of blood test and urine test, becoming the latest means of diagnosis.
The occurrence of many diseases and development can be left in the saliva of "chemical mark."
Dr. Wang made a bold vision - When a person began to have diabetes, or when his body in the cancer lesions, he proteins in the saliva will change? » If there is change, they can use "a healthy saliva" and "sick of saliva" to diagnose diseases. Studies have shown that the incidence of many diseases and development can be left in the saliva of "chemical mark." Therefore, as long as researchers to study the health of saliva components, the establishment of a health standard. Will be able to normal after the saliva of the patients and saliva for analysis, which compared various components of the number and status.
By analyzing the saliva to identify patients with bacterial infection of the virus and the DNA (DNA), antibodies and other compounds, on the condition of patients can understand. This number of Chinese medicine and we look cutting-Wen asked the traditional treatment methods are similar to the.
As many components in the saliva of blood concentrations much lower than the past, the technical difficulty of their detected. In recent years, as molecular biology, electronics, and other disciplines of the rapid development of means testing has been very sensitive, for example, polymerase chain reaction (PCR) technology, can enlarge the role, previously difficult to find the trace substances detected. Therefore, the saliva of the medical examination has become a new field of research.
Saliva can be used for diagnosis of HIV, hepatitis B virus and lung cancer diagnosis.
Almost three years, countries in the saliva of scientists have made great progress. Dr. Wang, who found that the saliva of some markers can be used for oral cancer, tongue and throat cancer, and other head and neck cancer diagnosis. Nearly two years, Dr. Wang in each inspection, cleaning teeth, they always Zhanshang the drop of saliva, put a small instruments. , Patients can get a print of the saliva test alone. This list will tell what his illnesses. Their 32 patients and the same number of healthy people for the detection, diagnosis accuracy rate was 91%.
U.S. Malamode professor leading the research team developed a new technology, can be detected with the virus in saliva and bacterial infections related to DNA, antibodies and other compounds. Specific operation is very simple, Malamode head with a rubber Cotton in the size of wiping the mouth and then insert the only credit card machines in the square. Less than one hour, will be able to know whether infected with the AIDS virus. At present this technology can diagnose AIDS, anthrax infection and other diseases. University of California at Los Angeles researchers also reported that they developed through the saliva of oral cancer detection of certain protein secreted by the new technology.
Last year in March, the U.S. government approved the rapid detection of HIV saliva way. Cotton used the dip in the gums, and then put their equipment, if the HIV antibody is positive, it will display the red line. This method of accurate rate of 99%. Saliva check illicit drugs in Europe and the United States have begun to use.
Now, the United States has three research centres are developing healthy saliva protein contained in the normal indicators, and to study their different levels of disease, is expected to be announced within two years of research findings.
In addition, South Korean scientists detected through the PCR technique in the saliva of hepatitis B virus. British scientists are looking to check saliva for the early diagnosis of lung cancer.
Saliva test sample simple, safe and reliable, there is no physical harm.
And blood tests compared to the benefits of saliva testing, sampling a simple, safe and reliable. Who one day may be secreted around the one l saliva, and each used to detect the saliva of a general need only two drops, sampling not be a problem. Moreover, you can frequently monitor your saliva, to observe the physical condition of the real-time changes. For example, you should take saliva samples of the patients, you can collect 10 times a day, but you definitely can not be pumped 10 times a day of blood.
On the one hand, saliva analysis of the blood to avoid the pain and embarrassment from the urine and reduce the psychological and medical treatment to physical pressure. On the other hand, in the course of urine can be part of many people cheating, but has not yet been found in the saliva of any of the means of cheating. In addition, the saliva test can greatly reduce the incidence of blood-borne infections.
Against the use saliva to diagnose the disease rather than a blood test, Dr. Wang said that the blood test is against nature. You must be punctured to blood vessels, which in turn may lead to infection. But if we use saliva, patients only need is the spitting. Saliva physical examination will be no infringement.
Just imagine, two years later, when you look at dentists, doctors will first take a sample of your saliva, before you start cleaning, such as oral. When you at the end of treatment, doctors will give you an analysis of saliva, above clearly had what you might read in, and that you should look for what doctors.
Saliva and blood components the same, only more dilute concentrations.
Dr. Wang in a recent dental conference, said: "If the eyes are the soul of the window, then the saliva is the body of the window, which is part of the body cycle. It from the body, it was not the color of blood, it is not sticky, Its composition and blood, everything. "
Over the years bacteria in the saliva of virus detection of the University of Pennsylvania Professor of Malamode that all substances within the body in the saliva of performance almost always have. , And other body fluids and blood, saliva, also contain bacteria, viruses and antibodies, drugs, growth factors, various proteins, the occurrence and development of many diseases will also leave traces in the saliva.
In fact, the latest and most advanced sensors, researchers can find the molecular level, saliva contains a variety of complex mixtures of protein, which contains DNA, RNA, fatty acids, protein, bacterial organisms, as well as in the human body Virus and can be used for diagnosis of other useful elements.
As a molecular biologist and a dentist, Dr. Wang daily contact with the saliva of the people, know very well that one reason. It can be said that various proteins in the blood of the same components present in saliva, only dilute the concentration of some relative. Have not the means to detect, but modern high-tech detection methods can also detected. This means that saliva can accurately reflects the blood and urine levels of various proteins in the changes.
