Methods: A total of 32 male SpragueDawley rats were subjected to a middle cerebral artery occlusion. In the hypothermic group, rats (n= 10) underwent selective brain hypothermia for 5 hours with the use of a novel surface coil with coolant circulating inside. In the control (n= 13) and sham groups (n=9), the rats were maintained at normothermia. After a period of 168 hours ischemia, animals were killed to measure the infarction volume of the brain stained with hematoxylin-eosin.Results: There were no significant differences in physiological parameters except for the temperature. The present style of hypothermia significantly reduced infarction volume in the cortex and caudoputamen.Discussion: The present results endorse the neuroprotective effect of our method of hypothermia in permanent focal cerebral ischemia at an endpoint of 1 week under the following two conditions: (1) reduction of muscle and caudoputamen temperature to 29 and 31°C, respectively; (2) maintenance of the mean arterial blood pressure above 90 mmHg during hypothermia.", pages = "613-619(7)", url = "http://www.ingentaconnect.com/content/maney/nres/2005/00000027/00000006/art00007" doi = "doi:10.1179/016164105X22110" }
