Development of a photochemical thrombosis investigation system to obtain a rabbit ischemic stroke model

Abstract Photochemical thrombosis is a method for the induction of ischemic stroke in the cerebral cortex. It can generate localized ischemic infarcts in the desired region; therefore, it has been actively employed in establishing an ischemic stroke animal model and in vivo assays of diagnostic and...
