Protective effect of naoyikang-containing serum on cultured hippocampus neuron injury induced by D-galactose / 中国病理生理杂志

ABSTRACT

AIM: To observe the protective effect of naoyikang-containing serum on cultured hippocampus neuron injury induced by D-galactose(D-gal).METHODS: Naoyikang-containing serum was prepared in rats administered with aqueous extract of naoyikang(6.84 g?kg-1?d-1).MTT,MAO-B and ATPase assay were used to measure the viability of hippocampus neurons.RESULTS: D-gal at concentration of 100 ?mol/L caused significant decrease in the viability of hippocampus neurons 24 h after the treatment.Naoyikang-containing serum increased the viability,ATPase activity and the expression of bcl-xl mRNA,decreased the MAO-B activity and the expression of bax mRNA in D-gal injured hippocampus neurons.CONCLUSION: Naoyikang-containing serum prevents hippocampus neurons from D-gal induced cytotoxicity.
