Hysteresis of airways and lung parenchyma

Imaging of sarcoidosis of the airways and lung parenchyma and correlation with lung function.

Imaging has a prominent role in the assessment of sarcoidosis diagnosis and outcome, which are extremely variable. Chest radiography staging helps predict the probability of spontaneous remission, and stage IV is associated with higher mortality. However, the reproducibility of reading is poor and changes in radiography and lung function are inconsistently correlated, which may be problematic f...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Compliance, hysteresis, and collapsibility of human small airways.

We tested the hypothesis that airway wall dimensions are important determinants for the mechanical properties of airways. Lung tissue was obtained from 31 smokers with different degrees of chronic obstructive pulmonary disease (COPD) who were operated on for a solitary lung lesion. Segments of small airways (n = 35) were mounted on cannulas in an organ bath and inflated and deflated cyclically ...

Quantitative study of parenchyma and small conductive airways in chronic nonspecific lung disease. Use of histologic stereology and bronchial casts.

Simultaneous morphometric studies of parenchymal loss and of internal diameters of membranous bronchioles' were carried out at autopsy in 42 cases of chronic nonspecific lung disease. In a few cases, a bronchial cast of the right lung was made according to the slightly modified Tompsett's method with the use of resin. The quantitative data were assessed in four anatomic groups: panlobular emphy...
