White blood cells are important blood cells in the blood. Besides white blood cells, human blood also contains red blood cells, platelets and plasma. As a part of the immune system, white blood cells help the body to resist infectious diseases and foreign objects. Under normal circumstances, the number of white blood cells in healthy adults is 4×109 ~1×109/liter of blood. \ x0d \ x0d \ white blood cells are also commonly known as immune cells. Besides blood, white blood cells also exist in the lymphatic system, spleen and other tissues of the body. \ x0d \ x0d \ There are five kinds of white blood cells in blood, which are lymphocytes, basophils, neutrophils, monocytes and eosinophils from high to low. \x0d\ White blood cells are a kind of nucleated blood cells. The number of white blood cells in normal people is 4000- 10000 /UL (microliter), and the number of white blood cells in blood varies greatly at different times of the day and in different functional states of the body. When the number exceeds 0/0000 per microliter/kloc, it is called leukocytosis; When there is no less than 4000 microliters, it is called leukopenia. When the body has inflammation (inflammation), leukocytosis will occur; Leukopenia can be hereditary, familial and acquired. Among them, acquisitions account for the majority. Drugs, radiation, infection, toxins, etc. It can reduce granulocytes, and drugs are the most common reason. \x0d\ What do you think of \x0d\ 1? First of all, we should carefully find the cause of granulocytopenia and choose the corresponding treatment measures according to the cause. If it is caused by drugs, you should stop taking them immediately. \x0d\2。 There are many kinds of leukopoiesis drugs used in clinic, but the curative effect is difficult to determine. For example, vitamin B6 and Leixuesheng can be used for various granulocytopenia. Vitamin B4, shark liver alcohol, inosine, deoxynucleotide, Kanglilong, etc. It has good curative effect on leukopenia caused by anticancer drugs, radiotherapy or chloramphenicol. At the same time of etiological treatment, you can choose 1-2 of the above drugs and take it for 4-6 weeks to see if it can restore white blood cells. Don't think that the more drugs, the better, but use several drugs at the same time. \x0d\3。 Adrenal cortical hormone can promote the release of bone marrow cells into peripheral blood circulation, which has a good and lasting effect in neutropenia caused by immune factors, such as systemic lupus erythematosus. \ x0d \ x0d \ Colorless cells in human and animal blood and tissues. It has a nucleus and can do deformation movement. White blood cells usually have active fluidity. They can migrate from blood vessels to blood vessels or from extravascular tissues to blood vessels. Therefore, white blood cells not only exist in blood and lymph, but also widely exist in tissues other than blood vessels and lymphatic vessels. White blood cells can swallow foreign bodies and produce antibodies, which play an important role in the healing of body injuries, resistance to pathogen invasion and immunity to diseases. \x0d\ White blood cells are divided into granulocyte and agranulocytosis according to whether there are granules in cytoplasm. Granulocytes can be divided into neutrophils, eosinophils and basophils according to their different particle staining characteristics. Agranulocytosis is divided into monocytes and lymphocytes. Lymphocytes are divided into several types according to their functions. The number of adult white blood cells is 5000 ~ 9000 per cubic millimeter, of which neutrophils account for 0.50 ~ 0.70, eosinophils account for 0.0 1 ~ 0.04, basophils account for 0.005 ~ 0.0 1, monocytes account for 0.03 ~ 0.08 and lymphocytes account for 0.20 ~ 0. The number of white blood cells in children's blood is higher than that in adults. Different physiological States (such as pregnancy) will cause changes in the number of white blood cells. When inflammation occurs, the number of white blood cells in the blood will increase significantly. \x0d\ White blood cells are a huge blood cell family. Their morphological structures and physiological functions are diverse, but they are not isolated from each other, and they play a synergistic role in the process of body protection, immunity and wound healing. Although it is a cellular component in blood, its function is more reflected in organs and tissues outside the circulation pipeline. Functionally, they are closely related to many cellular components in these organs and tissues, such as macrophages, mast cells and fibroblasts. \ x0d \ x0d \ The common causes of leukopenia are: virus infection, typhoid fever, etc. It is also caused by drugs. If it is drug-induced neutropenia, the drug should be stopped immediately, and leukogenic drugs, such as colony stimulating factor (CsF), lithium carbonate, alizarin diester, polyclonal antibody A, etc., should be used appropriately. Stop contact with radiation or other chemical poisons. Caused by hypersplenism, it is easy to get serious infection repeatedly, and splenectomy can be done. \x0d\\x0d\ Avoid taking medicine to avoid leukopenia caused by drugs. \ x0d \ x0d \ leukopenia refers to a group of symptoms caused by the continuous decrease of peripheral blood white blood cell count. Typical manifestations are dizziness, fatigue, weakness of limbs, loss of appetite, listlessness, low fever, etc., which belong to the category of "fatigue" in traditional Chinese medicine. Traditional Chinese medicine treats leukopenia by supplementing qi and nourishing blood, tonifying kidney and essence, strengthening spleen and nourishing stomach. \ x0d \ x0d \ Patients with leukopenia mostly belong to the category of deficiency syndrome or fatigue in traditional Chinese medicine, and the following foods should be avoided: \x0d\ 1. Persimmon: a cool fruit, which is easy to damage spleen and stomach yang. Anyone with leukopenia should be careful not to take it. \x0d\2。 Water chestnut: a product with cold nature, which consumes gas when it breaks down. People with weak white blood cells are not suitable for eating. People with leukopenia should not eat more. \x0d\3。 Betel nut: it is the fruit of breaking gas and hurting righteousness. People with weak leukopenia should not take it. \x0d\4。 Mint: a pungent and cool product, it can dispel wind and dissipate heat, but it only purges but does not replenish it. Therefore, all weak diseases, including leukopenia, should be avoided. \x0d\5。 Mustard: also known as potherb mustard, is regarded as a product of hair growth by the people, which has the disadvantage of consuming gas and damaging the body. The white blood cells are weak and should not eat more. \x0d\ In addition, patients with leukopenia should avoid eating raw radish, radish tassels, skulls, bitter gourd, kumquat and other gas-consuming and harmful products; Do not eat spicy, warm, dry and yin-damaging irritating foods such as pepper, pepper, cinnamon, dogwood, Alpinia katsumadai and litsea cubeba; Do not eat raw melons, chrysanthemums, bananas, crabs, mussels, snails and other cold, yang-damaging and spleen-damaging foods. \x0d\ Epidemiological and clinical studies have found that leukocytes are related to the occurrence and prognosis of cerebrovascular diseases. According to the literature, 10000 people's observation and research for two years show that leukocytosis is one of the precursors of cerebral infarction; The increase of neutrophils is the most relevant, especially for people under 65 years old. The higher the number of white blood cells in the blood, the greater the risk of cerebral infarction. There is leukocyte infiltration around the infarction tissue, and there is leukocyte aggregation in the capillaries around the infarction focus. Rheological study of white blood cells in patients with cerebrovascular disease also found that white blood cells play an important role in the pathophysiological process of cerebrovascular disease.
