Before the twentieth century it was thought that the blood type of one. Therefore, the ends of most attempts to move the blood tragedy. One of the most famous incidents, is the incident disease Ansent Pope Benedict VIII in 1492. This year, the pope was wounded disease hot doctors in the treatment of one of them suggested that the transfer of blood from three healthy young men to the Pope, perhaps cure. The result, as expected, is that the Pope died immediately after the operation.
Tault attempts and were mostly doomed to failure, which led to the prohibition of blood transfusions in Europe for decades as it has caused many deaths. It continued as it is until 1902. This year the world discovered the Austrian Carl Andashteiner that blood is made up of different factions with the code later by Α and Β and ΑΒ and О. This discovery has achieved what many a revolution in modern medical science earned by Carl Andashteiner deserved Nobel Prize for Medicine in 1930.
Not confined to the dimensions of this discovery to the medical field but Tdh to also include other areas of forensic science. Not only this but many now believe that the blood group related to nutrition, too. I will try in the following lines present an overview of a simplified blood groups and medical uses.
Blood groups and medical significance
The first question that comes to mind is what is the difference between the different blood types? The difference is simply the presence or absence, what can be called excess, "boats" Α and Β on the surface of red blood cells. If the blood vessel carrying blood is Vveselp Α Α If the boat was carrying blood is Vveselp Β Β If the authors of both blood is Vveselp ΑΒ. But if he were not with any one of them Vveselp blood is О (О nnhО stands for the word in German, which can be translated to: nil).
If the story of blood groups ended at this point what has been important for this class. But the reason that the blood transfusion mismatch usually leads to death, is that the transfer of red blood cells carrying a boat does not carry the blood cells of the future, lead to reactions dangerous because the body recognizes the cells as foreign bodies and therefore must be combated, as happens for example with the bacteria. But contrary to what usually happens when you attack the bacteria, this war is so strong immune endless alien pushers cells break down and eliminate them only, but also the destruction of the battlefield, the scene here is a person's future blood.
To clarify it more, the person who Α same blood does not contain his body on the boat Β. Thus will when you are typing a blood transfusion to a person Β Α same blood group will be identified on the red blood cells as foreign objects and will therefore be fighting which leads to complications kill the person. This is the basic idea behind the importance of matching blood. If we put this idea in Makhlitna we can simply select the appropriate blood type for each person.
Are there other blood groups?
Yes, red blood cell's surface can have a large number of "vehicle", other than Α and Β but they are less for the fact that non-conformity does not lead to serious complications, as is the case with Α and Β.
The second group in importance is Rh is simply that determine the positive or negative sign which we find to write next to the blood type. As for why a person who is the plus next to the same blood group and another carrying a negative sign is either the presence (+) or absence (-) compound known as Rh on the surface of red blood cells. Usually, it is not a blood transfusion (+) to a person (-) but it can be the opposite. This is because the cells had lost the boat does not lead to any complications (as is the case with blood group О).
Blood groups and Criminology
For many decades ago before the development of DNA tests, the blood groups play an important role in forensics. For example, select a platoon spot of blood on the victim's body may help to convict or acquit the defendant. For example, if we assume that the blood group of the accused was Α were different species to spill blood, then at least they will not help in the acquittal of the accused, will indicate the presence of another person in the crime scene. At present, DNA analysis is more accurate and credible analysis of blood groups, which led to reduce reliance on the analysis of blood groups in the science of forensics.
There are also other uses for the blood groups is not necessarily related to the knowledge of the crime. The most important, and as the blood group of genetically determined, is the use of blood groups in determining paternity. Therefore, we find that the blood groups are sometimes used to determine paternity is disputed or in hospitals when they get confused with the newborn babies. It is worth mentioning is that the analysis of blood groups can not rely on him at all times to determine paternity.
Nutrition and Blood
Theory of the relationship between blood groups and nutrition developed by Dr. Peter de Adamu several decades ago. Theory suggests a relationship between the vehicles to be called the Ictinat (or proteins Resin) in the food react with different blood groups, which may cause health complications. Dr. de Adamu suggests that people should eat foods that contain the Ictinat identical with certain blood types, he believes that there are types of Alketinat might fit or not fit with the person on the basis of blood type. Therefore, Dr. Adamu de simplify this issue than us and came out a long list of foods that are commensurate with each blood group. The fact that Dr. de Adamu wealth and fame through this major theoretical and A dozens of books discuss almost all of the same subject.
But the question is what the opinion of specialists in the science of nutrition in this type of diet? The fact that this theory is based on a scientific basis and that many nutritionists do not advise him for being a diet is not balanced. It is worth noting that many of the global health bodies did not recognize this type of diet, but the Food and Drug Authority Saudi Arabia had warned his followers.
The reason for the success of this diet with some people is simply that, after checking the list of foods that proposed by Dr. de Adamu, we find that foods that are recommended for people who have family or blood О Α are cruel (as opposed to the blood type and Β ΒΑ). As the statistics indicate that the majority of people have blood group О Α or it is not surprising that the success of this common type of diet to lose weight.
Conclusion that there is no scientific studies to prove the Court of this relationship. Indeed, some scientists are skeptical of the secretariat of Dr. de bloodied the scientific world when he stated in his books of more than twenty years that in the latter stages of clinical studies to prove the claims, but has not yet published any of them. Valsbb either to reverse the results of the studies were, therefore, the impact Maideih not publish them, or it did not work any clinical studies at all.
Goodbye Blood ..
Yes, I have bid farewell to days of blood groups. The reason is that the group of Danes find a way is the removal of vehicles Α and Β on the surface of red blood cells using a particular enzyme, making it similar to the red blood cells from blood group О and thus can be transferred to any person safely. This study, published in the journal "Nature Biotechnology" Since recently, may help in the future (of course, after conducting the studies necessary) to resolve the perennial problem in blood banks is the lack of the required quantities of each species is always blood.
