ABSTRACT
OBJECTIVES@#To observe the changes of expression of α-synuclein (α-syn) and neuronal apoptosis in brain cortex of acute alcoholism rats and to explore the mechanism of the damage caused by ethanol to the neurons.@*METHODS@#The model of acute alcoholism rat was established by 50% alcohol gavage. The α-syn and caspase-3 were detected by immunohistochemical staining and imaging analysis at 1 h, 3 h, 6 h and 12 h after acute alcoholism. The number of positive cell and mean of optical density were detected and the trend change was analyzed. The variance analysis and t-test were also performed.@*RESULTS@#The number of α-syn positive cell and average optical density in brain cortex of acute alcoholism rat increased significantly and peaked at 6 hour with a following slight decrease at 12 h, but still higher than the groups at 1 h and 3 h. Within 12 hours after poisoning, the number of caspase-3 positive cell and average optical density in brain cortex of rats gradually increased.@*CONCLUSIONS@#The abnormal aggregation of α-syn caused by brain edema and hypoxia may participate the early stage of neuronal apoptosis in brain cortex after acute alcoholism.
