Figure 2. Effect of treatment with ω-6/3, medroxyprogesterone acetate and meloxicam on abdominal contortions (writhings) induced by acetic acid in sham-operated rats and rats with peritoneal endometriosis.

Figure 2

Legend: ENDO: group with endometriosis; groups of rats subjected to the writhings test (0.6% acetic acid; 10 mL/kg ip). Sham-operated group: not treated; ENDO group: with endometriosis and not treated; and ENDO + ω-9/6 group (1.2 g/kg/day; vo), ENDO + medroxyprogesterone acetate group (5 mg/kg/3 days sc) and ENDO + meloxicam group (0.8 mg/kg/day). The Kolmogorov-Smirnov test indicated an approximately normal distribution for all variables. Due to the high heterogeneity of variances, two parametric tests were performed, according to Levene’s homogeneity test: one-way ANOVA or the Brown-Forsythe test.
