Alveolar lining fluid normally contains proteins of important physiological, antioxidant, and mucosal defense functions [such as albumin, immunoglobulin G (IgG), secretory IgA, transferrin, and ceruloplasmin]. Because concentrations of plasma proteins in alveolar fluid can increase in injured lungs (such as with permeability edema and inflammation), understanding how alveolar epithelium handles...
Alveolar epithelial fluid transport was studied 10 days after subacute lung injury had been induced with intratracheal bleomycin (0.75 U). An isosmolar Ringer lactate solution with 5% bovine serum albumin and125I-labeled albumin as the alveolar protein tracer was instilled into the right lung; the rats were then studied for either 1 or 4 h. Alveolar fluid clearance was increased in bleomycin-in...
The alveolar macrophages (AMs) constitute a morphologically and functionally heterogenous cell population. The adhesive properties of these cells are important for their role in host defence. To focus on the heterogeneity, a population of nonadherent macrophages were characterized functionally and morphologically. These cells were then compared with the total alveolar macrophage population. Alv...
pulmonary alveolar microlithiasis is an uncommon infiltrative pulmonary disease characterized by deposition of microliths in the alveoli. we present the case of a young adult with complaints of shortness of breath on exertion. chest radiograph showed innumerable small, dense nodules, diffusely involving both the lungs - predominantly in the lower zones. high-resolution ct scan illustrated wides...
normal 0 false false false en-us x-none fa microsoftinternetexplorer4 introduction : alveolar bone level is changed due to the balance between bone formation and resorption. radiographic examination has an important role in the diagnosis and treatment of periodontal diseases. this study was performed to compare the accuracy of vertical bitewing and periapical radiography in anterior mandibular ...
Elafin and secretory leukocyte protease inhibitor (SLPI) are two structurally related serine protease inhibitors present in the lung. The cellular origin of elafin in the alveolar space is unknown. It has been suggested that at least one alveolar leukocyte population express elafin. We therefore postulated that the alveolar macrophage, as the most numerous leukocyte in the alveolar space, expre...
To characterize the rate and regulation of alveolar fluid clearance in the uninjured human lung, pulmonary edema fluid and plasma were sampled within the first 4 h after tracheal intubation in 65 mechanically ventilated patients with severe hydrostatic pulmonary edema. Alveolar fluid clearance was calculated from the change in pulmonary edema fluid protein concentration over time. Overall, 75% ...
Monocyte-derived alveolar macrophages drive lung fibrosis and persist in the lung over the life span
Little is known about the relative importance of monocyte and tissue-resident macrophages in the development of lung fibrosis. We show that specific genetic deletion of monocyte-derived alveolar macrophages after their recruitment to the lung ameliorated lung fibrosis, whereas tissue-resident alveolar macrophages did not contribute to fibrosis. Using transcriptomic profiling of flow-sorted cell...
background and aim: the inferior alveolar canal must be constantly examined as an important anatomical landmark in the study of lower jaw, particularly posterior body and mandibular ramus sites, in dental and surgical procedures. in the present study, the effect of two pathological lesions, ameloblastomas and keratocystic odontogenic tumour, on canal displacement were investigated. materials an...
conclusions patients treated with ptu should be closely monitored and followed up, even if the drug has been used for several years. when patients develop progressive dyspnea with alveolar opacities on chest imaging that cannot be explained otherwise, alveolar hemorrhage should be an important differential diagnosis while investigating the case. early diagnosis and prompt discontinuation of the...
