Fig 1 Time-course of urinary eicosanoid concentrations in the anaphylaxis group. The log-transformed urinary eicosanoid concentrations are expressed as medians and interquartile ranges. Anaphylaxis groups are denoted by closed triangles. ∗P < .05 compared with baseline values. †P < .05 for the comparison between the urinary PGF2α and ent-PGF2α concentrations. Urine samples were collected at baseline and after the reactions.

Fig 2 Significant correlations among urinary concentrations of LTE4, 2,3-dinor-9α,11β-PGF2 and 9α,11β-PGF2 in the AIA and anaphylaxis groups. Urinary eicosanoids values are expressed by using the log scale. AIA and anaphylaxis groups are denoted by the closed circles and triangles, respectively.

Fig 3 Time-course of urinary concentrations of LTE4, 2,3-dinor-9α,11β-PGF2 and 9α,11β-PGF2 in the AIA and ATA groups. AIA and ATA are denoted by closed circles and squares, respectively. The results are expressed as in Fig 1. ∗P < .05 compared with each respective baseline values. ‡P < .01 in comparison of baseline values between the AIA group and the ATA group.

Fig 4 Time-course of urinary concentrations of PGE2, PGF2α and ent-PGF2α in the AIA and ATA groups. Abbreviations and the results are expressed as in Fig 3. †P < .05 in the comparison of the baseline values between the AIA group and the ATA group.
