Vyverberg - New York This correspondence is in response to a request to define asbestosis the effect of smoking on asbestosis mesothelioma of the lung cancer of the lung mesothelioma of the peritoneum the effect of cigarette smoking and asbestos exposure on cancer of the lung and the effecotf cigarette smoking on mesothelioma of the lung ASBESTOSIS tens o Asbestosis is a result of over exposure to airborne asbestos fiber It begins as an inflammation of the air sacs alveoli of the lungs The air sacs where air exchange between the lung and blood stream takes place The first change in asbestosis is an inflammation of these air sacs and the final air conducting channels respiratory bronchioles we which lead into the air sacs This inflammation leads to thickening of the walls of the air sacs and eventual laying down of scar tissue between weme the air sacs interstitial fibrosis As the scarring progresses it e involves the network of blood vessels which surround the air sacs eventually obliterating some of them This leads to increased resistance to blood flow through the lungs and causes the right side of the heart to enlarge and eventually fail cor pulmonale In summary the basic lesion in asbestosis is a blocking of air movement from the air sac into the blood which is then complicated by hindered blood flow through the lungs Death caused by asbestosis is frequently a result of the heart failure cor pulmonale ASBESTOSIS AND SMOKING The process of asbestosis as described above also takes place in the smoker In addition the smoke can cause bronchitis which is an inflammation of the air conducting systems taking air to the alveoli This can lead to a thickening of the wall of the air conducting systems a change in the wall's architecture including the loss of cilia Cilia are hair projections from the cell which aid in clearing foreign material from the respiratory tract Smoking causes these cilia to be less active and in severe cases to be destroyed Further smoking can actually affect the walls of the air sacs so that they dilate some of them breaking down to form larger chambers which in turn results in loss of elastic tissue in the lungs this damage to the air sacs and elastic tissue is emphysema 02 419 0933 oto Peery 7?
