pleural exudate

Pulmonary medicine An abnormal accumulation of protein-rich fluid in the pleural space Etiology Infection–bacterial, TB, viral, chylothorax, neoplasm, PTE with pulmonary infarction, GI disease, collagen vascular disease–eg, SLE, asbestosis, pancreatitis, traumatic tap, postcardiotomy, neoplasm Management Thoracentesis. See Pleural effusion.

The pleural exudate solidified to form a gelatinous covering on the lung (Figure, panel B).
If the cause of a pleural exudate remains unclear despite repeated thoracentesis with appropriate evaluation followed by an ultrasound-guided core needle/Abrams needle biopsy as described above, the next step would be to offer the patient a medical or surgical thoracoscopy.
Preparation of pleural exudate for the biochemical assays
5 ml of pleural exudate were washed with PBS (1:5) and centrifuged (1500rpm for 5min).
An aliquot of 200 [micro]l of pleural exudate from animals pre-treated with EAF, 35SF, 63SF, catechin or indomethacin, containing leukocytes was incubated with 200 [micro]l of nitroblue tretazolium (NBT).
An aliquot of 200 [micro]l of pleural exudate previously treated with EAF, 35SF, 63SF, catechin or indomethacin, was added to a reaction mixture containing 200 [micro]l 8.
Two aliquots of 200 [micro]l pleural exudate from rats previously treated with EAF, catechin, 35SF, 63SF or indomethacin, were submerged in liquid nitrogen for 10 s and exposed at room temperature (for rupture of plasmatic membrane) 3 times.
