The name of blood has already been mentioned. However, the understanding of blood composition and function has long been idealistic and incomplete.
Yes, some concepts are inferred from bit by bit phenomena and incomplete observations. Study blood systematically and scientifically.
Since the advent of the microscope, we have observed red blood cells (5672), white blood cells (5748) and blood with a microscope.
Small plate (5940), known as the tangible part of blood, is also the focus of hematologists' research. The liquid part of blood.
Fraction, also known as blood intangible component (or plasma), has been studied by biochemists and immunologists for many years. At present,
Hematologists pay special attention to the basic and clinical aspects of hemostasis and thrombosis. Since 0 1 century, dimensions have been
Hematopoiety and regulation of hematopoiesis in vivo with constant number of blood cells are also the focus of hematology research.
Although the discovery of blood cells has a history of 5: 132 1 1 year, the morphology of these cells is still an important content for hematologists to study. With the continuous improvement of blood cell observation technology, the accuracy of optical microscope is constantly improved. The staining technology makes the cell morphology clearer and easier to identify, and can distinguish various white blood cells and observe the abnormal morphology of various blood cells. The invention of special microscope enriches the concept of blood cell morphology. At present, the special microscopes used are: dark field microscope, phase microscope, polarizing microscope, interference microscope and electron microscope. hundred years
After several generations, I began to understand that blood cells are produced in bone marrow, and there are immature blood cells in bone marrow. These immature cells enter after maturity.
Blood. Bone marrow puncture needle was invented in 2006. Bone marrow can be sucked in like blood and pushed into the membrane. Under the oil mirror,
Observe. Since then, the observation of bone marrow cells has become an important part of the morphological study of blood cells. Similar techniques are also applicable to watering.
Morphological observation of blood cells in Pakistani tissues.
Blood cell count detection
The detection of blood cell count depends on blood cell pipette, blood cell counting plate and hemoglobin.
The invention of protein's quantitative and cell classification technology. United States 0 12.
Invented the world's first fully automatic blood cell counter, and so far there are various semi-automatic and fully automatic blood cell counting points.
Analyzers are constantly coming out and widely used in the world, which greatly promotes the development of blood cell counting and classified counting.
Understanding of red blood cells
The understanding of the function of red blood cells began in, and it is known that red blood cells have the function of carrying oxygen, which can be used for
Tissue participates in respiration, which was fully understood in 2000. I didn't know there was carbon in red blood cells until a few years ago.
Dehydratase, which can convert a large amount of carbon dioxide into carbonate ions and dissolve them in blood; At the same time, carbonate can also
Ions are converted into carbon dioxide and released in alveoli. This discovery not only clarified the respiratory function of red blood cells, but also improved them.
It is understood that red blood cells are closely related to blood acid-base balance. After 2000, it was determined that there was glycerol 3- diphosphate in red blood cells.
Aldehyde can be used as deoxyhemoglobin molecule, which is beneficial to tissue to obtain more oxygen. 4 years, affirmed the longevity of red blood cells.
Life is in heaven. Human blood transfusion can be safely carried out after the discovery of red blood cell blood group 567.
In the 1990 s, it was known that red blood cells needed glucose for in vitro preservation, and in the 1990 s, blood preserved in vitro had been used for this purpose.
For blood transfusion, blood banks were gradually established in the 1940s. The comprehensive understanding of erythrocyte glucose metabolism is many years later.
In recent years, the relationship between red blood cell structure and fat and protein has been clarified.
