Different macromolecules were administered intraperitoneally to stimulate formation of protein-rich ascitic fluid in rodents. Stimulatory effect of plant lectins depended on the attachment to cell surface carbohydrates, Canavalia ensiformis (ConA) lectin was used in the majority of experiments. The time course of ConA-induced ascites was divided into an early (up to 4 h) and a late (from 6 h on...

In order to assess the practical value of immunocytochemical techniques in routine cytological diagnosis, a panel of three monoclonal antibodies (anti-CEA, Ca 1 and HMFG-2) were used to search for malignant cells in 53 samples of pleural or peritoneal fluid from 41 selected patients. All these patients suffered from malignant disease, but neoplastic cells had not been reported on conventional c...

Hantavirus pulmonary syndrome (HPS), is a rodent-borne, acute, often fulminant cardiorespiratory illness. Noncardiogenic pulmonary edema is prominent in HPS as is cardiac dysfunction. Pleural effusions are commonly noted in patients with HPS and have been thought to be exudative. This report describes the prevalence and characteristics of pleural effusions by an assessment of chest radiographs ...

The concentration of ferritin was measured in the pleural fluid of 108 patients with pleural effusions. In all groups of patients the ferritin concentration was higher in pleural fluid than in serum. The greatest differences, with up to 100 times more ferritin in the pleural fluid, were found for patients with rheumatoid pleurisy, malignant effusions, and empyema. In patients with non-malignant...

PURPOSE To investigate diagnostic values of pleural fluid matrix metalloproteinase-2 (MMP-2), MMP-9, tissue inhibitors of metalloproteinase-1 (TIMP-1) and TIMP-2 measurements in tuberculous pleurisy(TP) and malignat pleurisy (MP). METHODS The study included 24 patients with TP, 22 patients with MP and 15 patients with pleural effusion of non-tuberculous and non-malignant origin as controls. M...

BACKGROUND Pleural effusion is a common cause of dyspnea in cats. N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement, using a first-generation quantitative ELISA, in plasma and pleural fluid differentiates cardiac from noncardiac causes of pleural effusion. HYPOTHESIS/OBJECTIVES To determine whether NT-proBNP measurements using second-generation quantitative ELISA and point-of-...

pleural effusions, as Dr. Kiropoulos mentioned. Momi et al2 and Hamed et al3 measured VEGF levels both in the serum and pleural fluid of tuberculous pleurisy patients. They found elevated VEGF levels both in the serum and pleural fluid of tuberculous pleurisy patients compared with congestive heart failure patients. In congestive heart failure patients, both of the studies reported higher VEGF ...

One hundred eighty-three patients had simultaneous blood and pleural fluid pH determinations. Thirty-six effusions were transudates, and 147 were exudates. In 46 effusions, the pleural fluid pH was less than 7.30; all 46 were exudates. A pleural fluid pH less than 7.30 was associated with the following six diagnoses: (1) empyema; (2) malignancy; (3) collagen vascular disease; (4) tuberculosis; ...

Tuberculosis (TB) is a major public health problem in developing countries including Nepal. One of the common presentations of TB is pleural effusion. The diagnosis of tubercular pleural effusion can be difficult because of the low rate of detecting tubercule bacilli by direct stain and culture of pleural fluid for acid-fast bacilli (AFB). Pleural biopsy can be useful but is invasive and requir...

Aim: To determine the sensitivity and specificity of pleural fluid ADA for the diagnosis of tuberculous pleural effusion taking the cut off value of ADA as ≥ 40 mg/dl. Methods: It was a prospective, analytical study comprised of 220 patients having pleural effusion. Sputum smear examination and sputum culture for mycobacterium tuberculosis, pleural fluid examination for protein, glucose, cell c...
