(A) Rats not subjected to sepsis which were not treated (CTL). (B) Rats subjected to sepsis (LPS). (C) Septic rats treated with an ethanolic extract of Brazilian olive leaf (LPSEx). (D) Septic rats treated with Brazilian olive oil (LPSOlv). (E) Septic rats treated with ethanolic extract of Brazilian olive + Brazilian olive oil (LPSExOlv). (F) Septic rats treated with omega-3 fish oil (LPSOmg). (G) Septic rats treated with palm oil (LPSPal). (H) Quantitative analyses of kidney sections stained for cleaved caspase-3. Data are reported as means ± SD. The significance level for the null hypothesis was set at 5% (p < 0.05). (╤╤) LPS group at 48 h compared to the CTL group at 48 h, (¥) for all groups at 48 h compared to the LPS group at 48 h (ANOVA analysis followed by Bonferroni post hoc test).
