Concentrations of L-DOPA, dopamine and DOPAC in striatal astrocytes at 4 h or 8 h after methyl-L-DOPA or DA treatment.

Striatal astrocytes were treated with methyl-L-DOPA, DA (200 µM) or control vehicle for 4 h or 8 h. The concentrations of L-DOPA, DA and DOPAC were measured by HPLC assay. ND: not detected. Data (pmol/mg protein) are presented as mean ± SEM (n = 4).
#p<0.001 vs. the corresponding 4-h treated group.

纹状体星形胶质细胞经甲基-L-DOPA、多巴胺（DA，200 µM）或对照溶剂处理4小时或8小时。采用高效液相色谱（HPLC）法检测L-DOPA、DA及3,4-二羟基苯乙酸（DOPAC）的浓度。ND：未检出。以pmol/mg蛋白为单位的数据以平均值±标准误（SEM）表示，每组样本量n=4。
#p<0.001，与对应4小时处理组相比。
甲基-L-DOPA或DA处理纹状体星形胶质细胞后4小时与8小时的L-DOPA、多巴胺及DOPAC浓度。
