Thirty-two male rats were divided into occlusion, preconditioning, postconditioning and both pre- and postconditioning groups. MCAo (120 minutes) was monitored with continuous cerebral tissue oxygen (O-2) pressure (PtiO(2)). Pre-conditioning comprised 10 minutes of MC-Ao, 24 hours prior to the 120 minute MCAo. The postconditioning algorithm was 30 seconds of reperfusion followed by 30 seconds of MCAo. This cycle was repeated 3 times at the onset of reperfusion. Comparison of infarct volumes showed a significant difference between the conditioned groups and occlusion group. Although there was better protection in the preconditioning group compared with the other two conditioned groups, the results did not reach statistically significant levels. The results suggest that preconditioning, postconditioning and pre/post conditioning have protective effects on cerebral ischemia.eninfo:eu-repo/semantics/closedAccessFocal cerebral ischemiaNeuroprotectionPostconditioningPreconditioningProgenitor-cell proliferationTriphenyltetrazolium chlorideTolerance acquisitionArtery occlusionBrainIdentificationReperfusionHypoxiaOxygenGenesNeurosciences & neurologyAnimalsCerebrovascular circulationDisease models, animalInfarction, middle cerebral arteryIschemic preconditioningMaleNeurologic examinationOxygenPressureRatsRats, sprague-dawleyReperfusionReperfusion injuryStatistics, nonparametricTime factorsArticle0002652239000192-s2.0-6254912901169369716519268597Clinical neurologyNeurosciencesIschemic Postconditioning; Reperfusion Injury; Mitochondrial Permeability Transition PoreAnimal experimentAnimal modelArticleBrain infarction sizeBrain ischemiaBrain oxygen tensionControlled studyIschemic preconditioningMaleNeuroprotectionNonhumanPriority journalRatMiddle cerebral artery occlusion
