erythrocyte membrane phospholipids

The phosphorus-containing lipid is called PL. Phosphorus, fatty acids and alcohols form a variety of different PLs, such as lecithin, lysophospholipids (phosphatidylcholine), cephalin (phosphatidylethanolamine) and cardiolipin (diphosphatidylglycerol), all of which constitute biofilms. The basic skeleton of the lipid bilayer. Phospholipids are also important substances that constitute and maintain the composition and function of cell membranes. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: After 8 pm on the day before the medical examination, you should start fasting for 12 hours, so as not to affect the test results. Normal value Thin layer chromatography phospholipid Rf value. Cholesterol 0.75 to 1.15. Phosphatidic acid 0.88. Phospholipid ethanolamine 0.62 ~ 0.7. Phospholipid serine 0.46 ~ 0.5. Phospholipid inositol 0.27 ~ 0.29. Shenhong sphingomyelin 0.15 ~ 0.17. Lysophosphatidylcholine 0.11. Clinical significance 1, hereditary spherocytosis (erythrocyte membrane phospholipid decreased, but the proportion of each component does not change). 2, hereditary oral polycythemia (phospholipid choline increased). 3, spinous polycythemia (normal or high cholesterol, normal or slightly reduced phospholipids). Precautions Before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. After inspection: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process The examination process: blood is drawn, blood is taken for examination, and venous blood is generally taken, and blood is drawn by a doctor or a nurse. The amount of blood drawn is determined according to the difference of the test content and the number of items. The blood volume is usually 2-20 ml, and the maximum is not more than 50 ml, and then examined by a doctor using chromatography. Not suitable for the crowd no. Adverse reactions and risks no.
