In this study, mice were subjected to 10 minutes of ischemic preconditioning, and persimmon leaf flavonoid was orally administered for 5 days. Results showed that the persimmon leaf fiavonoid significantly improved the content of tissue type plasminogen activator and 6-keto prostaglandin-F1 a in the cerebral cortex, decreased the content of thromboxane B2, and reduced the content of plasminogen activator inhibitor-1 in mice. Following optical microscopy, persimmon leaf flavonoid was also shown to reduce cell swelling and nuclear hyperchromatism in the cerebral cortex and hippocampus of mice. These results suggested that persimmon leaf fiavonoid can effectively inhibit brain thrombosis, improve blood supply to the brain and relieve ischemia-induced pathological damage, resulting in brain ischemic tolerance.展开更多
