Abstract

The kinetic of vascular and cellular alterations in the carrageenin-induced peritonitis was investigated (500 mcg) in Gallus gallus and the effect of the pre-treatment with dexamethasone (0.5; 1.0 or 2.0 mg/kg), indomethacin (2.0; 4.0 or 8.0 mg/kg), pyroxiean (20.0; 40.0 or 80.0 mg/kg), given by oral route 30 minutes before the inflammatory stimulus. It was observed that the highest increase in both vascular permeability and leucocyte accumulation ocurred respectively 150 minutes and 4 hours after the carrageenin injection. Polymorphonuclear leukocytes were the predominant cell type in the exudate obtained 2 and 4 hours after the stimulus. An equilibriun between polymorphonuclear and mononuclear cells was observed with 24 hours of inflammation and the latter cell type was predominant after 48 hours. The pre-treatment with indomethacin and pyroxiean significantly (p<0.05) inhibited the vascular permeability increase but not the leukocytes counts. Dexamethasone was significantly reduced both vascular permeability increase and leukocyte accumulation. These results suggest that eicosanoids have a role in the vascular permeability increase but it is less relevant in the leuchocyte chemotaxis in carrageenin-induced acute inflammation in fowls. The vascular permeability increase and cellular migration are independent phenomena when the effect of antiinflammatory drugs are concerned.
