Fig. 4From: Histamine 2/3 receptor agonists alleviate perioperative neurocognitive disorders by inhibiting microglia activation through the PI3K/AKT/FoxO1 pathway in aged ratsAn agonist of H2R or H3R inhibits exploratory laparotomy-induced inflammatory factor production in rat hippocampus. The levels of the proinflammatory factors TNF-ɑ, IL-Iβm and IL-10 were detected by ELISA. **P < 0.01 versus the control group. #P < 0.05, ##P < 0.01 versus the surgery group (n = 4).
