Macrophage-epithelial interactions in pulmonary alveoli [PDF]

Seminars in Immunopathology, 2016
Alveolar macrophages have been investigated for years by approaches involving macrophage extraction from the lung by bronchoalveolar lavage, or by cell removal from lung tissue. Since extracted macrophages are studied outside their natural milieu, there is little understanding of the extent to which alveolar macrophages interact with the epithelium, or

Tuberculosis: oral alveolus and pulmonary alveoli coexisting [PDF]

BMJ Case Reports, 2014
Tuberculosis of the oral cavity is uncommon in this antibiotic era. We report a case of a long standing non-healing ulcer of the right upper maxillogingival sulcus, found to be tuberculosis of a rather unusual site in the oral cavity, the alveolus.

Pulmonary Surfactant Function in Alveoli and Conducting Airways [PDF]

Canadian Respiratory Journal, 1996
Surface tension plays a very important role in aeration of the neonate's lungs. Pulmonary surfactant, which is inadequate in the premature infant, modifies surface tension during the act of breathing and is necessary for maintenance of alveolar stability.

ABSORPTION FROM THE PULMONARY ALVEOLI [PDF]

Journal of Experimental Medicine, 1947
Experiments upon dogs anesthetized with nembutal and lasting 4 hours, in which the right lymphatic duct and thoracic duct have been cannulated and collection of lung lymph and blood specimens was accomplished after intratracheal instillation of dog plasma, purified bovine serum albumin, crystallized egg albumin, and hemoglobin, have shown that the ...

THE ABSORPTION OF PROTEIN SOLUTIONS FROM THE PULMONARY ALVEOLI [PDF]

Journal of Experimental Medicine, 1937
Horse serum, crystallized hemoglobin, and crystallized egg albumin have been injected into the lung alveoli of dogs in which the entrances of the right lymphatics have been tied and the thoracic duct cannulated. Samples of blood and lymph have been taken following this injection.

Effects of E-Cigarette Vapor Smoke on Pulmonary Alveoli in Rattus norvegicus Lungs

Jurnal Respirasi, 2023
Introduction: Vapor is considered a safer alternative to tobacco cigarettes because the high nicotine content is less. However, vapor still contains substances that are classified as toxic to humans.

Ultrastructure of Pulmonary Alveoli of the Calf [PDF]

American Journal of Veterinary Research, 1974
SUMMARY 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.

Increased pulmonary blood flow leads to alveolar dysplasia during the early postnatal developmental stage [PDF]

Cell & Bioscience
Background Increased pulmonary blood flow (IncPBF), one of the most important features of many children with congenital heart diseases, is well-known as a prerequisite for the induction of pulmonary arterial hypertension.

Growth of the alveoli and pulmonary arteries in childhood [PDF]

Thorax, 1970
Since alveolar and airway growth have previously been studied in greater detail than has arterial growth, the present study establishes the growth pattern of the arteries and relates this to that of the alveoli and airways. The pattern of post-natal alveolar multiplication found is similar to that reported by Dunnill, but for all ages about 10% above ...

Histomorphology of the Pulmonary Alveoli of Goat (Capra hircus) [PDF]

Veterinary World, 2008
Histomorphological studies were conducted on the pulmonary alveoli of ten adult healthy goats of either sex. The alveoli were roughly spherical structures which opened into the alveolar ducts and alveolar sacs or respiratory bronchioles.
