Abstract

In this study, the temporal development of focal cerebral infarction induced by permanent middle cerebral artery occlusion (pMCAO) and the effects of piracetam, a derivative of γ-aminobutyric acid widely used in clinical practice as a nootropic agent, on infarct area and volume were investigated. pMCAO caused a cerebral infarct whose size progressively increased after 3, 6, 9, and 24 h. Piracetam (125 mg/kg i.p.), administered 6, 9, and 22 h after pMCAO, did not reduce pMCAO-induced brain infarct area size detected at the 24th hour. By contrast, when this agent was administered at the doses of 250 and 500 mg/kg, it caused a marked reduction of the infarct area size. This reduction was observed in almost every brain slice affected by pMCAO, although statistical differences (p
