5,14-HEDGE (30 mg/kg, s.c.) or 20-HEDE (30 mg/kg, s.c.) was given 1 h after administration of endotoxin. Mean values ± SEM are presented. Numbers in parentheses indicate the number of animals studied per group. a indicates a significant difference from the corresponding value seen in rats treated with saline (vehicle) (P < 0.05). b indicates a significant difference from the corresponding value seen in the rats treated with vehicle and endotoxin (P < 0.05). c indicates a significant difference from the corresponding value seen in the rats treated with vehicle and 5,14-HEDGE (P < 0.05). d indicates a significant difference from the corresponding value seen in the rats treated with endotoxin and 5,14-HEDGE (P < 0.05). e indicates a significant difference from the corresponding value seen in the rats treated with vehicle and 20-HEDE (P < 0.05). f indicates a significant difference from the time 0 value within a group (P < 0.05). g indicates a significant difference from the time 1 value in each group (P < 0.05).
