The potentiating effect of chloramphenicol succinate in rat carrageenininduced acute pleurisy. Inhibition by indomethacin and dexamethasone
Keywords:Chloramphenicol, Pleurisy, Carrageenin, Dextran, Indomethacin, Dexamethasone.
AbstractThe effect of indomethacin and dexamethasone on PMN cell migration was studied in relation to chloramphenicol in the pleural cavity of rats, 4 hours after local injection of carrageenin or dextran. Pre-treatment of rats with chloramphenicol succinate (30mg/kg), ip, every 12h, during 4 days, potentiated the migration of PMN leucocytes to the inflamed cavity, when carrageenin (150mcg) was used as an irritant. However, responses to dextran (100mcg) remained the same. Chloramphenicol pre-treated rats that received
indomethacin (2mg/kg, per os, 30min before carrageenin) or dexamethasone (0.25mg/kg, ip, 30min before carrageenin) showed inhibition of potentiated cellular responses. Mechanisms of the potentiating effect of chloramphenicol on the acute carrageenin-induced inflammation remains unclear.
