Here,we found that gastrodin ameliorated pentylenetetrazole（PTZ）-induced epileptic seizures with improvement of the electroencephalographic pattern in mice. Further studies demonstrated that gastrodin decreased the levels of the pro-inflammatory cytokines interleukin-1b and tumor necrosis factor-a while increasing interleukin-10, an antiinflammatory cytokine in the brain. Furthermore, gastrodin attenuated the PTZ-induced microglial activation along with inhibition of mitogen-activated protein kinases,c AMP response element binding protein, and NF-j B. Our data suggest that gastrodin attenuates seizures by modulating the mitogen-activated protein kinase-associated inflammatory responses.展开更多
