摘要
目的:研究牛磺酸拮抗铅对原代培养的皮层神经元生长及存活的影响。方法:通过建立新生大鼠皮层神经元原代培养,用不同浓度醋酸铅染毒和给予牛磺酸干预,观察神经细胞的生长和存活情况。结果:终浓度为10-8mol/L的醋酸铅即可抑制神经元突起生长,导致细胞生长活力下降,终浓度为1.6×10-3mol/L的牛磺酸能够抑制这种损害作用,促进神经元生长。结论:牛磺酸能够拮抗铅抑制神经元生长和存活的毒性。
Objective:To study the effect of taurine on protection against lead toxicity in cultured cortex neurons. Methods:Put taurine and different concentrations of lead acetate in cultures of cortex neurons and observe the length of dendites and the growth activity of neurons. Results:At the concentration of 10-8 mol/l lead acetate the growth of cultured cortex neurons were decreased and even the cells died. Taurine at the concentration of 1.6×10-3 mol/L could protect against lead toxicity and promote neuron to grow. Conclusion:Taurine can protect from lead acetate toxicity in cultured cortex neurons.
