Figure 4From: Electroacupuncture pretreatment attenuates cerebral ischemic injury through α7 nicotinic acetylcholine receptor-mediated inhibition of high-mobility group box 1 release in rats Neurological scores and infarct sizes at 72 h after reperfusion. (A) Representative photographs of coronal brain sections following infarction, stained with 2,3,5-triphenyltetrazolium chloride. Red area is healthy tissue; white area is infarct tissue. Pretreatment with EA significantly reduced infarct sizes (B) and improved neurological scores (C) and the α7nAChR antagonist α-BGT reversed the beneficial effect of EA pretreatment (n = 10). *P < 0.01 vs. MCAO, #P < 0.01 vs. EA+MCAO.Back to article page
