Abstract: The aim was to investigate the expression of Bax protein in the apoptosis of primary cultured rat cortical neurons following hypoxia/reoxygenation(H/R) and the protective role of extract gingo biloba (EGB). The cortical neurons of E16~17 d fetal rat was primarily cultured. The apoptosis model of primary cultured cortical neurons following H/R was established by using TUNEL staining and electromicroscopy. The expression of Bax protein was investigated with immunohistochemical method. H/R can cause apoptosis of primary cultured rat cortical neurons. The apoptosis cell increased with the time, reaching peak value at H 8R 18 ; EGB could decrease the percentage of apoptosis. The expression of Bax protein increased with hypoxia time, EGB could inverse the expression of Bax. Conclusion: EGB could significantly inhibit the expression of Bax. It may be one of the mechanisms of apoptosis.
