比色法

It's required for VK_1 in the present compendial monographs that the content of menadione should be strict controlled and the other impurities are controlled as related substances using colorimetry or TLC method.

目前各国药典维生素K_1的质量标准中，都是采用比色法或TLC法检查甲萘醌，而其他的杂质则作为"有关物质"同时进行检查。

Methods The cells were divided into 5 treatment groups（10,25,50,75 and 100 μmol·L-1 QUE）, blank control and menstruum control group. The rat C6 cells were cultivated to 1×106·mL-1 in the RPMI 1640 medium, then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h. The change of cell cycle was also observed by flow cytometry after the cells were treated with 50 and 100 μmol·L-1 QUE for 48 h. The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 μmol·L-1 QUE for 48 h were detected by immunocytochemical methods.

按QUE浓度分成10、25、50、75及100 μmol·L-15个处理组和空白对照组及溶剂对照组，大鼠脑胶质瘤C6细胞在RPMI 1640培养基中生长达1×106·mL-1后，在96孔板中分别加入上述浓度的QUE继续培养，每组设3复孔，作用24、48及72 h，采用MTT比色法检测QUE对大鼠脑胶质瘤C6细胞的增殖抑制情况，流式细胞术对50及100 μmol·L-1的QUE作用48 h的大鼠脑胶质瘤C6细胞进行周期分析，免疫组化法检测50 μmol·L-1的QUE作用48 h 的p53和bcl-2基因产物。
