['s: To determine whether talc (TL) and silver nitrate (SN), two effective pleurodesis agents, induce a systemic inflammatory response in the acute phase of experimental pleurodesis in rabbits.', 'Samples of blood and pleural fluid were collected after 6, 24, and 48 h from rabbits injected intrapleurally with 3 mL saline solution, TL (400 mg/kg), or 0.5% SN, and were assayed for WBC count, percentage of neutrophils, and levels of lactate dehydrogenase (LDH), interleukin (IL)-8, and vascular endothelial growth factor (VEGF). The pleural liquid production was compared in the three different groups. A sample of blood collected from animals preinjection was used as the control.', 'At 6 h after pleural injection, the mean blood WBC count and percentage of neutrophils were significantly elevated in the TL group, whereas the mean LDH and IL-8 levels were significantly increased in the SN group. VEGF was undetectable in the preinjection serum and saline solution-injected animals, but was increased in the serum after the pleural injection of both TL and SN to a comparable degree. SN elicited a more intense acute pleural inflammation reaction than did TL, with higher WBC count and IL-8 levels found in the pleural fluid, mainly within the first 6 h. LDH and VEGF levels, and pleural liquid production were also higher for SN, and they increased with time.'] Do talc and silver nitrate induce systemic inflammatory effects during the acute phase of experimental pleurodesis in rabbits?
