Neuroprotective Effects of Bushen Decoction Against Glutamate-Induced Neurotoxicity in PC12 Cells

补肾方含药血清促进PC12细胞增殖及其拮抗谷氨酸神经毒作用的研究(英文)

Aim The enhanced effect of Bushen (Kidney-tonifying) decoction (BS) oncultured PC12 cell proliferation and its antagonistic action on neurotoxicity induced by glutamatewere investigated by serum pharmacological method of the Chinese material medica (CMM) in vitro.Methods The effect of BS on cultured PC12 cell activity and its antagonistic action on neurotoxicityinduced by glutamate was observed by MTT method. Flow cytometry and fluorescence microscopetechniques were employed to observe the antagonistic effect of BS on early period apoptosis of PC12cells induced by glutamate. Results The serum with BS was able to enhance activity of PC12 cells andexert antagonistic effect on glutamate-induced neurotoxicity. Meanwhile, these beneficial effectsproduced by BS were found to be the strongest in 20% concentration of in serum BS. Moreover, it caninhibit apoptosis of PC12 cells induced by glutamate , which occurs in the early period. ConclusionBS may exert a potential neuroprotective effect.

目的运用中药血清药理学方法研究补肾复方含药血清(BS)促进体外培养的PC12细胞增殖及其拮抗谷氨酸兴奋性神经毒损伤的作用。方法以MTT法观察BS对体外培养的PC12细胞活力的影响及其拮抗谷氨酸损伤的作用,采用流式细胞仪观察BS对谷氨酸所诱导PC12细胞凋亡的影响。结果BS含药血清可以增强PC12细胞活力,拮抗谷氨酸的兴奋性神经毒作用且在20%浓度时作用最强,并且能够抑制谷氨酸诱导的PC12细胞早期凋亡。结论补肾方BS可能具有神经保护作用。
