3. Figure 2
Loss of the total weight of endometriotic lesions in LXA4 group. The mice in the LXA4 group were treated with LXA4 5 μg/kg, every 8 hours, starting 3 days before the EM induction, for 24 days, whereas the controls were treated with vehicles. Horizontal bars represent the means of each group.

No effect of estrous cycling in LXA4 group. Methylene blue-stained vaginal smears at different stages of the estrous cycle: (A) diestrus, (B) proestrus, (C) estrus, (D) metestrus). Magnification, ×400. (E) The dots represent the number of mice that went through different lengths of estrous cycle over a period of 24 days as determined by daily vaginal smear.

5. Figure 4
Concentrations of MMP-2 and MMP-9 in peritoneal fluids measured by ELISA. The mean levels of MMP-2 and MMP-9 were significantly reduced in peritoneal fluids of LXA4 mice compared with those in the EM group, which were significantly higher than those in sham-operated group. Error bars indicate SD. ∗P<.05, ∗∗P<.01, EM versus Sham; +P<.05, ++P<.01, LXA4 versus EM.

6. Figure 5
(A) MMP-2 mRNA and MMP-9 mRNA expression in peritoneal cavity cells. The levels of MMP-2 mRNA and MMP-9 mRNA in peritoneal cavity cells were significantly lower in the LXA4 group than those in the EM group, which were significantly higher than those in the sham-operated group. Error bars indicate SD. ∗P<.05, ∗∗P<.01, EM versus sham; +P<.05, ++P<.01, LXA4 versus EM. (B) MMP-2 mRNA expression in ectopic and eutopic endometria. The levels of MMP-2 mRNA in both ectopic and eutopic endometrial in the LXA4 group were significantly lower than those in the EM group, which were significantly higher than the those in the sham-operated group. Error bars indicate SD. ∗P<.05, ∗∗P<.01, EM versus sham; +P<.05, ++P<.01, LXA4 versus EM. (C) MMP-9 mRNA expression in ectopic and eutopic endometria. The levels of MMP-9 mRNA in both ectopic and eutopic endometria in the LXA4 group were significantly lower than those in the EM group, which were significantly higher than those in the sham-operated group. Error bars indicate SD. ∗P<.05, ∗∗P<.01, EM versus sham; +P<.05, ++P<.01, LXA4 versus EM.

Inhibitory effect of LXA4 on the activities of MMP-2 and MMP-9. (A) MMP-2 and MMP-9 proteins detected by gelatin-substrate zymography on the basis of their gelatinolytic activity and molecular masses (proenzyme and active forms). (B) Densitometric analysis. The relative enzymatic activities of MMP-2 and MMP-9 in peritoneal fluid in LXA4 group were significantly reduced compared with those in EM group, which were significantly higher than those in the sham-operated group.
