LTB ₄ content in lung and cerebral cortex homogenates from antigen-challenged asthmatic guinea pigs. LTB₄ content was detected by reversed phase high-performance liquid chromatography (RP-HPLC). Data are expressed as the mean ± S.E.M. (n = 8 per group). ^#P < 0.05, ^##P < 0.01 vs. the NS-vehicle group;*P < 0.05, **P < 0.01 vs. the OVA-vehicle group; ^†P < 0.05, ^††P < 0.01 vs. the OVA-LTB₄ 30 ng group. OVA, ovalbumin; NS, saline.
