's general knowledge of cause of disease of the elderly's bronchiectasis

's general knowledge of cause of disease of the elderly's bronchiectasis
Bronchiectasis is one layer of bronchus continuation expansion that destroyed and caused of tube wall elasticity layer and skin. It has illness coming on importantly the factor is blocked for infection and bronchus that the bronchus lung organize.
1.Bronchiectasis is continued and taken place at chronic bronchitis, bronchus pneumonia, pulmonary tuberculosis and foreign matter sucking, tumour after measles and whooping cough,etc. more.Baby's whooping cough in the past, measles was the most common reason, infect in the majoritily with the blue negative bacillus of leather at present, there are mushroom and anaerobe, because the repeated infection of the respiratory tract causes the chronic suppurative inflammation of the bronchus tube wall, having damaged every storey tissue of the bronchus wall, including smooth muscle, collagenous thread, important support structure of bronchus walls such as elasticity fiber and cartilage,etc.. Meanwhile, chronic inflammation that lung organize and fiber take pull tube wall around the bronchus, and is in charge of factors such as pressure increasing and attraction of thorax negative pressure,etc. in while coughing and inhaling, cause the bronchus to be unusual and expand enduringly. It can be that tumour, foreign matter suck or in charge of the consequence of oppression of swelling lymph node outside that the respiratory tract is blocked, they can result in, carry the intersection of bronchus and the intersection of lung and the intersection of organization and infect or getting obstructive the intersection of lung and piece far. Bronchus slender right middle period such as lung, how around form a cluster lymph node, often is because of lymphnoditis swelling to oppress the bronchus, cause right the intersection of lung and middle period piece, infect repeatedly, call middle period syndrome. It is the good hair position of bronchiectasis. The fibrous tissue of pulmonary tuberculosis shrinks and pulls or membrane tuberculosis causes and in charge of blocking narrowly in the bronchus, can cause bronchiectasis.
2.Congenital development defect and inherent cause can also cause bronchiectasis, such as enormous trachea - bronchiectasis, may the intersection of bronchus and the intersection of smooth muscle and cartilage and fibrous hypoplasia of elasticity, structural weakness and elasticity of tube wall are worse and cause.Achondroplastic or the elastic fiber is insufficient, lead to the fact some tube wall is weak or the elasticity is bad, transfer with sinusitis or viscera by the nose to the location (right location heart) ,Known as Kartagener syndrome. Lung sac fiber it takes to be because the intersection of tip and lung organize development to be bad, small detailed bronchus take the form of column, bag expand, bronchus the intersection of mucus and gland secrete a large number of mucus, cause, block the intersection of lung and piece and continue, send, infect, cause bronchiectasis. This disease is often autosome recessiveness and hereditary pancreas bag fiber disease lung complication. In addition, some hereditary X - it resists tryptic deficiency disease to be can be with bronchiectasis in patient.
3.The organism immunological function lacks proper care, immune defect, such as low gamma globulin blood disease brings out the repeated airway infection, can cause bronchiectasis.In addition suck the gas of corrosivity if ammonia or NO2, damages the trachea, the mucous membrane of bronchus can also cause bronchiectasis while carrying on and taking place and is infected with repeatedly.
