Specially sending pathologic _'s general knowledge of cause of disease of calm disease of hemosiderin
[The cause of disease is studied ]
Not bright. Infer that relates to several respects, the abnormal development of leather cell at the lung, the quality among the lung exists the machinery of the capillary bleeds unstably and repeatedly; Immunological function obstacle, have in lungs such as 1/8 of the patients acidophil soaks, and loose cells, the plasma cell increases, some patients condense and collect and test the masculine gender. Some patients can erupt rheumatoid simultaneously, much arthritis, myocarditis, and Goodpasture syndrome appears.
Other reasons mentioned are that animal's albumens are taken in, sucks noxious substance,etc. (such as organic pesticide) .
[Pathology changes ]
The lung weight increases, tangent plane it is obvious filling the air brown pigmentation, the mirror is examined there can be leather necrosis at alveoluses, unless hyperplasia, some capillary expand,alveolus and among last macrophages containing iron blood flavin at quality, there can be quality among filling the air nature fibers on later stage. The electric mirror has extensive capillary endothelial cell swelling to brief on, the inner membrane has albumens that is deposited. After the lung tissue is washed, dry, the iron content is still higher than normal lung by 5- 200 times while organizing. And proportional to condition.
