- Abstract:
- Inflammatory exudates obtained in rats after subcutaneous implantation of carrageenin-soaked sponges were found to contain relatively large amounts of 15-hydroxy-5,8,11, 13-eicosatetraenoic acid (15-HETE) and smaller amounts of cysteinyl-leukotrienes (LT) in addition to LTB4, thromboxane (TX) B2 and prostaglandin (PG)E2. Concentrations of 15-HETE and cysteinyl-LT were high 5 hours after sponge implantation and decreased significantly within 24 hours. This time-course, which is similar to that of TXB2, but differs from that of PGE2, suggests migrating leukocytes as a major source of 15-HETE and cysteinyl-LT. Aspirin, sodium salicylate, dipyrone (100 mg/kg each) and indomethacin (2 and 20 mg/kg) decrease the concentrations of cyclooxygenase products of arachidonate metabolism, but did not significantly affect levels of 15-HETE. Cysteinyl-LT were increased by 20 mg/kg indomethacin, but remained unaffected by 2 mg/kg indomethacin and by the other non-steroidal anti-inflammatory drugs (NSAID) tested. 15-HETE and cysteinyl-LT could play a mediator role in inflammation. In addition, they could modulate the release and effects of other inflammatory mediators.
