摘要: 利用高效液相方法观察了氯化钾对培养人神经母细胞瘤细胞系(SH-SY5Y)细胞谷氨酸释放的影响。发现:当培养液中存在钙离子时,一定浓度的氯化钾(10~30mmol/L)可使SH-SY5Y细胞谷氨酸释放增加,但氯化钾浓度超过40mmol/L时,谷氨酸释放增加不明显;当培养液中没有钙离子时,氯化钾不能使SH-SY5Y细胞谷氨酸释放明显增加。结果表明氯化钾对SH-SY5Y细胞释放谷氨酸的作用与钙离子相关.

关键词: SH-SY5Y, 氯化钾, 谷氨酸, 钙离子

Abstract: The influence of KCl on the release of glutamic acid from culture human neuroblastoma cell line(SH-SY5Y)was observed by using HPLC. The results of the experiments showed that KCl(10~30 mmol/L)incresed the concentration of glutamic acid in the cell culture when calcium ion existed in the culture medium. When the concentration of KCl above 40 mmol/L, there was no increment of glutamic acid released from the cell. The increase of glutamic acid induced by KCl was not found when there was no calcium ion in the culture medium. The results indicate that calcium ion is an important facto in the release of glutamic acid induced by KCl in SH-SY5Y cell culture.

Key words: SH-SY5Y, KCl, glutamic acid, calcium ion
