Hello ! Steemian's We will talk about plasma and platelets.
The blood plasma :
is a transparent liquid that tends to yellowish. The most important characteristic is that it has no shape. It has 55% of the total blood volume in the human body. It is very important for the transport of water, salts, food and hormones.
Blood plasma functions :
Blood plasma has two important functions within the body: it works to transport the food needed for the cell from the place of absorption or manufacture to the rest of the body.
Work on the transfer of metabolic processes within the body.
Blood plasma components:
Water:
which accounts for 90% of the size of the plasma, and its importance: It acts as a solvent for some substances, and transfers organic and inorganic substances, and it works to maintain the temperature of the body.
Proteins:
which account for 7% of plasma volume. The most important of these proteins are:
* Albiumin: 60% of plasma proteins.
* Glopiolin: 35% of the volume of plasma proteins.
* Fibrinogen: The ratio of 4% of the volume of proteins in the plasma. Other proteins make up 1% of the volume of proteins, such as enzymes, hormones, and other substances. The importance of proteins is that they regulate metabolic processes, act on blood clotting, defend the body, and maintain osmotic pressure.
Inorganic ions:
Examples include bicarbonate, chlorine, phosphate, calcium, sodium, magnesium, potassium, and its mission is to maintain osmotic pressure and maintain pH.
Organic substances such as:
Carbohydrates, especially glucose, fat, amino acids, lactic acid, and cholesterol. Their importance lies in their use to produce energy for cells and growth.
Gases dissolved:
They are very important for cellular respiration.
Nitrogenous waste: Examples include urea, uric acid and aluminum ions.
Blood plasma for facial injection :
Blood plasma is a safe cosmetic technique that relies on the injection of the face, neck, scalp or other platelets that are pulled from the patient and re-injected into the same patient again and in different places, which in turn stimulate stem cells. On the division, and thus renewal of damaged cells and tissues, and the number of sessions of this technique between three to four sessions, depending on the situation to be addressed, and separated between each session and about about a month.
Benefits of blood plasma for the face :
Nourishes the skin, activates blood circulation in the face. Give the skin freshness, vitality. Get rid of fine lines in the face, delay the appearance of wrinkles, signs of aging. Stimulates the production of collagen in the body, thus giving the skin strength and cohesion. Rejuvenates skin components and gives them softness. Relieves scars caused by acne. Dark circles around the eyes. The cheeks are inflated if the plasma is added to the self-fat. Unify skin tone. The color of the lips, and beautifully protruding.
Platelets :
They are flat, not cells, and do not contain organelles or nuclei. They are irregular in shape, help the body to form clots to stop bleeding. If a blood vessel is damaged, it sends signals that are picked up by platelets to reach the site of damage. , And spread on the surface of the vessel by a process called "adhesion", to form clot or clot, repair damage and stop bleeding, where when platelets reach the site of infection grow sticky claws to help them to cohesion and stability, and sends chemical signals to attract more platelets to the site of clotting In process Called "assembly". Platelets are made in bone marrow along with white and red blood cells. When produced and circulating in the bloodstream, they live for 8 to 10 days, with a normal population of 150,000 to 450,000 per microliter of blood.
The lack of platelets :
The lack of platelets causes the inability to manufacture blood clotting and coagulation in the event of any injury or scratching in the patient's body.
The causes are divided into three main types:
failure to make enough platelets in the bone marrow, increase platelet fracture in the blood, Platelets break down in the spleen or liver.
The following are the most common causes of platelet insufficiency.
Spleen enlargement - which can be caused by a number of disorders - may clog a lot of platelets, causing a decrease in the number of platelets in the blood circulation .
Bone marrow may not make enough platelets due to one of the following conditions:
anemia. Cancer in the bone marrow, such as leukemia. Cirrhosis of the liver (liver scarring). Folic acid deficiency. Bone marrow injuries (very rare). Metastatic dysplasia syndrome (bone marrow does not make enough blood cells, or makes damaged cells). Vitamin B12 deficiency. Lack of blood-induced platelets, and the lack of this case because of the use of drugs that lead to thrombocytopenia such as sulfa drugs, and some antibiotics, medicines, epilepsy and rheumatism.
Take drugs that lead to thrombocytopenia such as sulfa drugs, some antibiotics, epilepsy drugs, and rheumatism. Kaspach-Merit syndrome, the disease is a large swelling of the blood vessels with the presence of clotting within these vessels, and this swelling may be internally, which can not be detected, a very serious disease; because it may cause heart failure, and can be treated in this case by Surgery and the use of radiation and laser. Sporadic thrombocytopenia, and this disease causes clots in the small vessels that cause when the brain injury convulsions and loss of sight and mood swings. Pregnancy: Deficiency caused by pregnancy is usually mild and improves shortly after birth. Immune thrombocytopenia:
This type of autoimmune disease, such as lupus and rheumatoid arthritis, causes any abnormality in the immune system in the body that may trigger immune cells to destroy platelets, which often affects children. The presence of bacteria in the blood:
Acute bacterial infections involving blood (bacteremia) may lead to the destruction of platelets. Intravenous coagulation disease.
In fact, treatment is not necessary in cases where the lack of platelets is simple and has no symptoms, while treatment becomes binding in cases where platelet insufficiency is severe or if the patient experiences bleeding. In general, treatment of platelet insufficiency depends on, among other things: determining the main disease or problem that caused the lack of platelets, the cause may be the presence of a particular disease, or the treatment of drugs affect the work of the plates and production. The use of drugs to raise the rate of platelets in the blood, such as corticosteroids, in special cases given immunosuppressants, such as immunoglobulins, or rituximab, which reduces the immune attacks on platelets. Blood transfusion or platelets, this method is used to treat patients with persistent bleeding, or those who have a massive lack of platelet count. The spleen is removed, and the doctor resorts to this step when other methods fail to treat acute platelet insufficiency.
If the thrombocytopenia is severe, the doctor may resort to more powerful treatments such as prescription drugs such as steroids and immunoglobulins. In addition, the patient may need blood transfusions or some of his products if the patient is suffering from continuous hemorrhage. Doctors resort to the removal of the spleen; to reduce the clogged platelets.
