Abstract
Rodent models of focal cerebral ischemia that do not require craniotomy have been
developed by intraluminal suture middle cerebral artery occlusion (MCAo). Mouse MCAo
models have been widely used and extended to genetic studies of cell death or recovery
mechanisms. Therefore, we compared surgery-related parameters and techniques between such
rats and mice. In rodent MCAo models, has to be considered body temperature during the
operative period, as well as the need for the use of a standardized tip in terms of the
outer diameter of probes. Induction of focal cerebral ischemia was measured by
neurological dysfunction parameters. Our methods could induce stable moderate-severity
ischemic brain injury models and histological alteration at 24 hr after MCAo surgery.
Moreover approximately 80% (rats) and 85% (mice) survival ratios were shown indicating
with model engineering success. Finally, we described and compared major parameters
between rats and mice, including probe size, thread insert length, operation and occlusion
periods, and differences in the procedures.
