Asbestos – Related Diseases
Silicates form a family that asbestos fibers irrigated crystals. Based on epidemiological studies, occupational exposure to asbestos concerns
Localized fibrous plaques, or rarely, diffuse pleural fibrosis
Pleural fluid
Parenchyma interstitial fibrosis (asbestosis)
Bronchogenic Carcinoma

A growth rate-asbestos workers Asbestosis family members of cancer related to the potential dangers of asbestos in the general public has been warned. True public health policy at the level of exposure and this old building could not be found in schools, some experts expensive software that asbestos fibers in air is suspended for the environment and the controversial question is the wisdom up to 100 times less standards.Visit allow the doctors to help
Pathogenesis. Concentration, size, shape, and various forms of asbestos problem resolution, if cocurs disease. That asbestos two geometric forms: sepentine (fiber, and cluster) and amphiboles (hard, brittle and fiber stright) flexible serpentine form Chrysotile asbestos industry chemicals used in the calculations are for. Amphiboles crocidolite, amosite, Tremolit to include Anthophyllite and actinolyte. Because amphiboles, but more often, more than chrysotiles this amazing series of terms pathogens, malignant pleural tumers (mesothelioma) and is particularly important in terms of induction.
Some studies have shown mesothelioma almost always is related to exposure to amphiboles. And very few cases of mesothelioma in chrysotile workers emerged because chrysotile contaminated with amphibole is to Tremolit.
Hard and flat appearance and aerodynamic characteristics and pathogenicity, most amphiboles are associated with resolution. Chrysotiles, with their more flexible structure of the cluster can be affected as the upper respiratory tract and has been removed by the mucociliary elevator. In addition, once the lung, because it is more soluble than amphiboles tissue crysotiles gradual leaching trap.
However, in May, flat, stiff and therefore more profound and amphiboles airsteam lung epithelial cells penetrate into and where to reach and will be delivered intersticis to participate. Length play a role in pathogenicity and Amphibole fibers are, more than 8 mm or more, short thick is 0.5 mm thinner than harmful. However, the two coils and increasing doses fibrógenos and amphiboles asbestos related diseases, except an increase in exposure is correlated with the rate of mesothelioma amphibold is about. Unlike other inorganic dust, asbestos, and the tumor started acting as a tumor promoter of May
Potentially toxic substances are absorbed by asbestos fibers but fiber certainly contribute to oncogenic. For example, asbestos fibers and adsorption for cigarette and tobacco smoke carcinogens in asbestos workers as a striking synergy between the development of bronchogenic carcinoma may be important. Asbestos exposure and smoking, with time lead to an increase in asbestos workers work alone, an increase of 5 times it bronchogenic carcinoma in asbestos exposure 55 times the risk of lung cancer.
Asbestosis, like other pnumoconioses the lung parenchyma with macrophages and other cells and the interaction depends on fiber and inhalation. The first injury, and small air channels and occurs at bifurcations where the best hardness and penetrated into fibers. Alveolar and interstitial macrophages, and thus try to eat fiber and the factors triggering chemotactics clean and publications to raise fibrógenos this response arabulucular. And fibers, and deposition and permanent version Arabulucular widespread chronic interstitial inflammation and interstitial lung fibrosis causes. I completely understand why silicosis is not a process of diffuse interstitial fibrosing nodular disease and asbestosis. More widespread distribution of asbestos capacity or skills to alveoli epithelial cells, or both may be about to get more consistent for influence.
Merry Christmas! I hope everyone has an amazing and safe New Year!
