What about asbestosis?
summary
In life, asbestosis is a common disease, its etiology is many, mainly because of smoking a lot of harmful substances caused by the disease, in the discovery of asbestosis, patients should pay attention to, strengthen the understanding of the disease and nursing, patients do not have too much pressure, master the cause of the disease, please take a look at the cause of asbestosis.
What about asbestosis?
First, asbestos is a group of silicates containing cellulose and different concentrations of magnesium, iron, aluminum, calcium and sodium. There are two main types: serpentine salts (wet asbestos) and amphibole asbestos (crocidolite and crocidolite, etc.). Wet asbestos fiber is short and thin, soft and curly, suitable for textile; The fibers of crocidolite and chrysotile are coarse, long, hard and highly pathogenic. All kinds of asbestos have the characteristics of fine fiber and bendable crystal. It has the characteristics of acid resistance, alkali resistance, heat insulation, insulation, good flexibility and strong tensile resistance. It can be made into a variety of pressure resistant, wear-resistant, heat insulation and insulating materials, which are widely used in industry.
Second, asbestos exposure mainly causes four types of lung diseases, namely asbestosis, pleural plaque and pleural calcification, lung cancer and mesothelioma. Asbestos related diseases are mainly caused by asbestos mining, mineral processing, crushing and transportation. Engaged in secondary asbestos products processing industry, including unpacking, ginning, weaving asbestos rope, asbestos tile and asbestos board. However, there are many kinds of potential exposed workers, such as builders in shipyards, locomotive factories and boiler factories, brake and clutch lining manufacturers and assemblers in automobile factories, and workers using insulation materials, heat insulation materials and plumbers can inhale asbestos dust, all of them are potential asbestos exposed workers. All of them have the possibility of asbestos related diseases.
Third: asbestos dust particles are needle shaped and easy to enter the lower lobe along the bronchus when inhaled into the lung, with a diameter of less than 3 μ M of asbestos fibers deposited in the respiratory bronchioles, and some of them reached the alveoli. Through mechanical stimulation and chemical action, cause bronchioloalveolar inflammation. Asbestos dust deposition in the lung after the formation of dust focus, macrophages phagocytosis, followed by fibrous tissue proliferation, resulting in alveolar septum, interlobular septal blood vessels, peribronchial and visceral pleura showed diffuse pulmonary fibrosis. The results of tissue culture showed that asbestos was less toxic to macrophages than silica, and less toxic to fibroblasts, which indicated that asbestos directly stimulated fibroblasts, promoted proline to hydroxyproline, accelerated collagen synthesis, and promoted the formation of fibrosis. Animal experiments show that long fiber has tumorigenic activity. The incidence of lung and pleural malignant tumors was significantly higher.
matters needing attention
Patients have a clear grasp of the cause of asbestosis, right? In life, patients should regularly go to the hospital for treatment, cause attention, master the treatment method, patients try to keep a happy mood in life, bravely face the occurrence of the disease, and timely go to the hospital for relevant treatment.
