The potentiating effect of chloramphenicol succinate in rat carrageenininduced acute pleurisy. Inhibition by indomethacin and dexamethasone
The 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, potentia...

| Sumario: | The 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. |
