| Objective To investigate the effect of Buchang Naoxintong containing serum (BNCS) for antagonizing hypoxia-induced apoptosis of primary cultured cortical neurons with the sero-pharmacological method. Methods Primary cortical neurons from neonate rats (within 24 h) were cultured and induced into hypoxia model on the 7th day, which were then treated with different concentrations of BNCS. Cell apoptosis was detected qualitatively and quantitatively; and further verified by agarose gel electrophoresis through analyzing internucleosomal DNA fragmentation of the neurons. Besides, neuron viability was tested by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and change of nuclear morphology was observed by Hoechst 33258 staining. Results After treatment with BNCS, the viability of the hypoxia neurons improved with significantly reduced neuron apoptosis. Conclusion Buchang Naoxintong can protect cortical neurons from hypoxia-induced apoptosis. |
