| Outline of Final Research Achievements |
The present study revealed that periventricular leukomalacia, cerebral cortical necrosis, and bilateral focal symmetrical encephalomalacia (necrosis of basal ganglia) were seen also in cattle as perinatal brain damages. Fluoro Jade C, a nerve injury marker, Alzheimer precursor protein A4, an axonal degeneration marker, and Hypoxia inducible factor-1a and vascular endothelial growth factor, both a hypoxic marker, were useful for detecting these lesions. These markers were useful to visualize the lesions of an encephalopathy without obvious histopathological changes in some cases. Histopathological features of bovine cerebellar cortical degeneration were also clarified in the present research.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、これまで良く知られていなかった周産期脳障害がウシにも存在することが明らかになった。また、神経傷害マーカーや低酸素マーカーがウシでも適用できることを示すとともに、ウシの小脳皮質変性症の特徴所見を明らかにすることができた。これらの知見は、今後の症例診断に有用な情報を与えるものである。
