| 摘 要： | 为探索同步测定大成骨细胞膜Ｃａ＾２＋－ＡＴＰ酶和Ｎａ＾＋、Ｋ＾＋－ＡＴＰ酶活性的方法。采用孔雀绿比色法测定磷以反映酶活性。结果显示：Ｃａ＾２＋浓度以及成骨细胞传代增减的代数是影响酶活性的重要因素。

| Abstract: | The aim of this study was to find a method to measure simultaneously the activities of Ca(2+)-ATPase and Na+, K(+)-ATPase of rat osteoblast membrane. In this test, Ca(2+)-ATPase and Na+, K(+)-ATPase released inorganic phosphate (Pi) from ATP, and Pi was determined by colorimetric method using malachite green dye to show ATPase activities. Ca2+ concentration and osteoblast culture generation were important factors affecting ATPase activities. Ca2+ could elevate membrane ATPase activity. When Ca2+ concentration reached 40 mumol/L, ATPase activities were improved. Ca(2+)-ATPase activity decreased with the increase of osteoblast culture generation. Ca(2+)-ATPase activity was lower than Na+, K(+)-ATPase activity in osteoblast membrane. This method is simple, sensitive and reliable. |
