Luteolin improved hippocampal injury and reduced inflammatory factors through PPARγ in MCAO/R treated rats. A The changes of pathology in damagedCA1 hippocampal region were observed by HE staining, nerve cells shrink (red asterisks). B The levels of IL-1β, IL-6 and TNF-α in serum by ELISA. Vs. sham group, ^**p < 0.01; Vs. vehicle group, ^##p < 0.01; Vs. luteolin-25 group, ^&&p < 0.01; Vs. luteolin-50 group, ^{^^}p < 0.01
