So are the red blood cells — red blood cells
If the vampire aristocrat count Dracula described in the novel by the Irish writer Bram Stoker, actually existed, it has moved from Transylvania to Japan. The fact that Japanese scientists have invented the present artificial blood. The study is published in the us . According to the results, the artificial blood can be transfused to all patients, regardless of blood group. According to experts, this discovery can become a real breakthrough in medical practice.
Know how to distinguish robots from humans? If you watched the cartoon “Futurama”, you may remember that in one episode the main character was placed in a psychiatric hospital for robots. When he was discharged, he was sure that he is a real robot. Hero was deluded exactly as long as not hurt and did not see his own blood. But what people blood?
still from the animated series “Futurama” season 3 episode 11
This is only 6-8% of the mass of the human body. The blood consists of an aqueous solution called plasma, cells and cell fragments, such as erythrocytes, leukocytes and platelets. In General, the blood — is a liquid connective tissue of the internal environment of the body, which circulates through the system of blood vessels. The blood circulation takes place under the force of rhythmically cutting the hollow fibro-muscular organ — the heart. The blood has a characteristic red color due to the presence in the blood cells — red blood cells — hemoglobin, which carries oxygen.
Blood performs a large number of vital functions: transports oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs, delivers nutrients to body tissues, regulates body temperature and connects organs and systems of the body and other protective and mechanical functions.
And you know what your blood group? If you for some reason do not know, suggest to fix it. And here's why: each person has an individual blood type, which he endowed with from birth. Blood group remains constant throughout life. When it comes to blood groups, experts mean the ABO system (a-be-zero), and Rh (rhesus factor).
do you Know your blood type?
Blood type determines the antigens of the so-called — they are in red blood cells or erythrocytes. Antigen is called a structure on the cell surface. In the case that an antigen is foreign to the body, a protective response will not keep itself waiting long. Also important is the RH factor. Belonging to the RH factor (Rh) is negative or positive. Depends on the status of Rh antigen D, which is on the surface of red blood cells. If the D antigen present on the surface , the status is considered RH positive, and if the D antigen is absent, the RH-negative. Therefore, when blood transfusion is necessary with a precision of 100% know blood type and her RH factor.
you may need to patients in a variety of cases, but the most common is blood loss due to trauma. Due to the fact that the blood group of each person is different, there are donor centers where people donate blood voluntarily. That is why the discovery of Japanese scientists — an incredibly important event for medicine. Currently, however, artificial blood has not been tested on humans.
Scientists from the Medical College of national defense held on 10 rabbits. All animals were traumatized and suffered from severe blood loss. In the study survived 6 rabbits. In the control group in which rabbits conducted the transfusion of this blood, the results were the same. At the same time, experts note that there are no side effects from the use of artificial blood was not detected.
Scientists conduct experiments not only with rats
According to reports Japanese newspaper The Asahi Shimbun, in the near future, scientists will move on to human trials. The invention may prove extremely useful in cases where certain type of blood available for transfusion. Experts say that to prepare enough blood for transfusion in remote regions such as Islands, is hard enough. Artificial blood can save many lives. Also, according to the study, artificial blood can be transfused directly to the ambulances, as it would not be necessary in the determination of blood group of patients.
Another advantage of artificial blood is the fact that it can be stored at room temperature in the course of the year. In the artificial blood contains platelets, which ensure that the blood can clot and wounds will heal in time, as well as red blood cells, which deliver oxygen to vital organs.
I Hope that human trialswill be successful in the future doctors will be able to save more number of lives.
