用酶学比色法测定10例再生障碍性贫血慢性期患者红细胞膜(Na~+·K~+)-ATP酶活性,结果为每小时2.577±0.86微克分子磷/毫克蛋白(均值±标准差),明显高于正常组。红细胞膜(Na~+·K~+)-ATP酶活性与糖酵解相偶联。再障慢性期(Na~+·K~+)-ATP酶活性升高,可作为病情变化的辅助指标。
The activity of erythrocyte membrane (Na ~ + · K ~ +) - ATPase in 10 patients with chronic aplastic anemia was determined by enzymatic colorimetry. The result was 2.577 ± 0.86 micromoles phosphorus / mg protein per hour (mean ± standard deviation ), Significantly higher than the normal group. Erythrocyte membrane (Na ~ + K ~ +) - ATPase activity is coupled with glycolysis. Achilles tendon chronic phase (Na ~ + · K ~ +) - ATPase activity, can be used as auxiliary indicators of disease changes.
