Lung pathogenesis. V. The stereotype development of bronchial and lobular pathological reactions (a systemic approach).

Taking into account the present data upon the general stereotyping of different pathological processes of various nature challenged by the extremely numerous environmental actions, a structural analysis of the peculiarities presented by such reactions at the lung level, mainly on bronchial and lobular structures, was attempted. It was shown that the first damaged structures and their behaviour impose the peculiarities of the subsequently developed reactions which manifest a certain stereotyping, different when bronchi or lobules are the first lesioned. Relationships between bronchial and lobular lesions were also analysed and pointed out their role in the development of the whole complex process of the lung. This special aspect of lung complex pathogenesis was also emphasized.
