Must pay attention to blood disease caused by benzene poisoning prevention


The shoe workers exposed to benzene occurs because the white disease. Benzene is a fat solvent, for a variety of industries, such as leather, footwear, rubber, dyes, grasshopper manufacture of drugs and so on. Benzene is very volatile substances, more toxic by the love into the human body easily fixed in the fatty tissue, such as nerve tissue, adipose tissue, bone marrow, adrenal gland, liver and spleen and so on. Into risk of benzene poisoning and chronic, acute benzene poisoning mainly fixed in the brain and adrenal glands, the first stimulus to the nervous system, only after the paralysis,abercrombie and fitch sale, the nerve center of the main bulb damage when chronic benzene poisoning, mainly fixed in the bone marrow, Therefore, chronic benzene poisoning and blood diseases are closely related. First, benzene in the bone marrow to stimulate the bone marrow cell proliferation, inhibiting cell division and later, l from the edge type of abnormal cells or become polyploid. After screening of these abnormal cells to become malignant clone a cell, you can become wrinkled from leukemia caused by benzene, first, from leukemia bone marrow hyperplasia often low, the peripheral blood pancytopenia, later to become leukemia,moncler paris, which is the first to become aplastic anemia (aplastic anemia),nike free, myelodysplastic syndrome (MDS), was developed from leukemia. As the current Pan Jing Xin, aplastic anemia due to benzene poisoning reported 80 cases (including 42 cases of acute aplastic anemia, 6 down in death within 6 months), Yang Xiaofeng and other reports of benzene poisoning MDS3 cases (1 death). Sixth National Conference of aplastic anemia aplastic anemia due to benzene poisoning reported 38 down. Hubei Province from leukemia in 2061 the body as a group found in workers exposed to benzene aplastic anemia and acute myeloid leukemia in 1 case since, much higher than the general population incidence (National aplastic anemia and leukemia incidence from the 0 .74/10 million and 2.76/10 million), far more than the actual number of cases of fear. I have leukemia and aplastic anemia in the national survey of risk factors found in benzene and chronic aplastic anemia, chronic leukemia, acute non-lymphocytic leukemia pathogenesis, especially with the M: close, OR 1.54. Benzene poisoning caused aplastic anemia, leukemia, mostly acute. Acute aplastic anemia, MDS and acute leukemia from, are considered a serious condition, it is difficult to cure diseases. Acute aplastic anemia was built in the early stage I,moncler outlet, the mortality rate of 100, was adopted from the anti-lymphocyte globulin treatment, international and domestic, but also the response rate of about 80 to 30 ~ 7OMDS into acute leukemia, acute to obtain from the blood disease remission, to be used in the treatment of antibiotics, blood components and a variety of input chemotherapy drugs, in recent years has used a variety of hematopoietic growth factors, these drugs are very expensive. Although hematopoietic stem cell transplantation to induce some acute aplastic anemia and acute leukemia patients from the cure, but dangerous, frequently after a group of transplant physicians, nurses,moncler jakke dame, guarded day and night treatment. Short takes a lot of manpower, material resources, for individuals, families and countries are a great burden. However, since adult acute leukemia, but long-term survival - the mortality rate remains high. Since reform and opening, the rise of township enterprises is undoubtedly anti-China's economic development, improve people's living standards, national strength played an important role. Township enterprises lacking in benzene as solvent factory, the footwear industry is well developed in some places, due to lack of knowledge, and neglect-resistant protection of workers in the plant operation has a high concentration of benzene. National public safety standard for benzene concentration 0.04g / L, and some competing plant benzene concentrations up to 0.3 ~ 1.2g / L, exceeding the national standard several times to several hundred times, it is more unitary staggering figure. Workers in such long-term operation of the air, the harm can be imagined. Benzene poisoning can be prevented, the need to improve contact with the working conditions of workers exposed to benzene. Proposed to mobilize the national levels of government, at all levels of health and epidemic prevention station, inventory of benzene plant protection facilities, not those of Le Fu sets boast improved the state to protect the health of workers, the people's misfortune, national misfortune.
