Russian holidays - National Donor Day

The hero of one of the American teenage TV series presented an unusual surprise to his beloved on Valentine's Day He went to the hospital, where he donated blood, which incredibly impressed the girl In this way, the guy showed gratitude, because he himself needed multiple transfusions as a child If Dylan from Beverly Hills 90210 (we are talking about this character) lived not in the USA, but in the Russian Federation, he most likely timed his act to coincide with April 20th It is on this date that Russia celebrates National Blood Donor Day April 20, 1832 is considered the day when the successful transfusion of this liquid tissue was first used and recorded in the annals of domestic medical practice The manipulation was carried out in St Petersburg by a young obstetrician Andrei Martynovich Wolf The mother's loss of blood turned out to be so great that the doctor decided to borrow from her husband's bloodstream The operation went well, the woman survived Wolf was lucky: the recipient and donor did not conflict either by group or by Rh factor The doctor at that moment simply did not suspect this Doctors were not aware of the existence of important categories such as blood groups until the early 20th century Only in 1900, Karl Landsteiner, a doctor from Austria, was able to identify and explain the cause of hitherto unknown deaths that occurred after infusion After all, if there is rejection due to group mismatch, the recipient either suffers from severe complications or dies The patient's immune system rejects what it considers foreign tissue After the discovery of the grouping according to four main characteristics was made, the therapeutic method of transfusion began to develop very quickly At the same time, humanity has learned to separate blood into the necessary fractions and components, as well as preserve it This made it possible to deliver the biomaterials necessary for transfusion to points remote from collection stations The word “donor” itself is translated as giver, from the Latin verb donare - to give as a gift But, as it turned out, a person who donates his tissues for free only wins in the case of blood donation His body triggers mechanisms to activate hematopoiesis, resulting in stimulation of defenses and immunity As a result, donors, according to statistics, live 4-5 years longer than the average person They tolerate significant blood loss more easily, are less likely to suffer from cardiovascular diseases, and their cholesterol levels are normal Since no more than 450 ml of biomaterial can be taken at a time, and up to one and a half liters are needed for transfusion, at least three donors are required per recipient Despite the fact that 15-17% of the population can become blood donors, in practice there are ten times fewer proactive volunteers Therefore, popularizing information about the need to replenish donor blood supplies is so important Perhaps, having learned about National Blood Donor Day in Russia, more people will come to the transfusion station wanting to give hope and life
