Model of pleural fluid turnover
Journal of Applied Physiology, 1993A model of pleural fluid turnover, based on mass conservation law, was developed from experimental evidence that 1) pleural fluid filters through the parietal pleura and is drained by parietal lymphatics and 2) lymph flow increases after an increase in pleural liquid volume, attaining a maximum value 10 times greater than control.

Pleural fluid characteristics of tuberculous pleural effusions
Heart & Lung, 2010Mycobacterium tuberculosis (TB) infection of the pleural space is an important cause of pleural effusion in areas of high TB prevalence. Microbiological analyses of pleural fluid in the acute setting may be negative. Consequently, investigations may proceed to more invasive techniques, such as pleural biopsy or thoracoscopy. Ongoing research has led to

Pleural Fluid Analysis in Chylous Pleural Effusion
Chest, 2008Chyle is a noninflammatory, lymphocyte-predominant fluid that may cause a pleural effusion as a consequence of thoracic duct leakage into the pleural space. Although chyle is reported to have protein concentrations in the transudative range, chylous effusions are typically exudative, as defined by the standard criteria.

Pleural Lymphatics as Regulators of Pleural Fluid Dynamics
Physiology, 1991Pleural fluid is filtered across the parietal mesothelium in the top of the pleural cavity and removed by lymphatic stomatas in the more dependent mediastinal and diaphragmatic regions. The pleural lymphatics act as a feedback system that regulates pleural liquid volume and its protein composition around a low volume set point.

Diseases of the Chest, 1950
1) A change in the routine manner of positioning the patient from the vertical or sitting to the lateral recumbent method of approach is proposed. 2) The lateral recumbent position for doing a chest tap, with the fluid side dependent, has safety, completeness, speed and convenience. 3) By placing the patient in the lateral recumbent position,

Penetration of Ciprofloxacin into Pleural Fluid
Journal of Chemotherapy, 1993The penetration of oral 1000 mg/day ciprofloxacin into pleural fluid is investigated in 15 patients with exudative pleural effusion. After 4 days of ciprofloxacin therapy ciprofloxacin concentrations were measured in plasma and pleural exudate simultaneously by high-performance liquid chromatography (HPLC). Mean serum ciprofloxacin level was 1.58 +/- 0.

Pleural fluid exchange in rabbits
Respirology, 2007Background and objectives: The study was designed to better characterize pleural fluid absorption in rabbits with the following two objectives: to determine the relative absorption of saline versus high‐protein solutions, and to identify the relative rates of absorption of dextran molecules of varying sizes.Methods: Twenty New Zealand white rabbits ...

Masquerade With Mediastinal Pleural Fluid
JAMA: The Journal of the American Medical Association, 1975A TRIANGULAR density in the right paraspinal area has been considered as evidence of right lower lobe atelectasis. 1-3 Fluid density merging with the right margin of the heart may be interpreted as an enlarging heart. 4 Finally, with known disease of the right lower lobe, a subsequent increase in density off the right margin of the heart may suggest ...

Antinuclear Antibodies in Pleural Fluid
Chest, 1994Systemic lupus erythematosus (SLE) frequently involves the pleura with resultant pleural effusion. Previous studies have reported that detection of antinuclear antibodies (ANA) in pleural fluid using animal tissue as substrate was a sensitive and specific method for distinguishing SLE pleural effusions from other etiologies. The HEp-2 ANA, which uses a

Mucopolysaccharides of Serum and Pleural Fluid [PDF]
Nature, 1960 THE use of paper electrophoresis has enabled several investigators to establish the presence of acid mucopolysaccharide components in various tissue extracts1,2 and urine3. Two such substances, staining with toluidine blue, were found in human aortic tissue4; concentrated human urine contained three components which stained with alcian blue5.
