Pulmonary administration of Am80 regenerates collapsed alveoli
Journal of Controlled Release, 2014Chronic obstructive pulmonary disease (COPD) is an intractable pulmonary disease, which causes widespread and irreversible alveoli collapse. Nevertheless, there is no effective drug therapy that regenerates lung tissue or prevents the progression of COPD and clinical management of patients remains mostly supportive.

Host Defense in Pulmonary Alveoli
Annual Review of Physiology, 1992,and alveolar), airway reflexes (cough and sneeze), a mucociliary escalator covering most of the airways, and specialized cell-mediated defenses (phagocytic and non-phagocytic). Lung infections (pneumonias) are frequently precipitated by the failure of one or more of these mechanisms.

Ultrastructure of Pulmonary Alveoli of the Calf
American Journal of Veterinary Research, 1974SUMMARY The ultrastructural characteristics of lung of the normal calf were basically similar to those described in other mammals. The alveolar septums were comprised of an epithelial lining resting on a relatively thin basal lamina overlying a varied thickness of connective tissue which surrounded the capillaries.

Dust elimination from pulmonary alveoli
Environmental Research, 1980Abstract Some alveolar macrophages that engulf asbestos particles move through alveolar walls and spaces to the larger bronchioles. They pass through the bronchiolar wall to reach the lumen where they are elevated by cilia and pass out of the lung.

Ultrastructural evidence for the innervation of human pulmonary alveoli
Experientia, 1980Electron Microscopic observations of the biopsied human pulmonary alveoli showed the occurrence of unmyelinated axons in the interstitium near the type I pneumocytes. These axons very likely have sensory functions.

Gaseous diffusion from alveoli into pulmonary arteries
Journal of Applied Physiology, 1964In 40 patients, during right heart catheterization a catheter with a platinum tip electrode was wedged in a branch of the pulmonary artery. With the electrode acting as part of a potentiometer, signals were recorded following single inhalations of hydrogen.

Lymphatics of the Human Pulmonary Alveoli: Preliminary Report
Chest, 1970The subpleural lymphatics of a normal human lung were injected with a dilute, green-colored latex solution after the lung had been made edematous by normal saline infusions. The tracheobronchial tree was then filled with a white latex, following which the preparation was submerged in concentrated HCl to achieve corrosion of the tissues.

Ultrastructure of pulmonary alveoli and macrophages in experimental Legionnaires' disease
The Journal of Pathology, 1983AbstractGuinea pigs, rhesus monkeys and marmosets infected with Legionella pneumophila in small particle aerosols developed an acute fibrinopurulent bronchopneumonia. Changes from 24 hr included exudation into alveoli of protein‐rich, often fibrinous fluid and many polymorphonuclear leucocytes (PMN) and macrophages.

[The pores of Kohn in pulmonary alveoli].
Bulletin europeen de physiopathologie respiratoire, 1983The pores of Kohn are apertures in the alveolar septum, which allow the communication of two adjacent alveoli. Their existence has been most disputed, but was lastly supported in man and adult mammalians by observations from electron microscopy. Located between the meshes of the capillary network, these alveolar apertures are circular or oval, and are ...
