| 摘 要： | 本研究对123例月经周期正常妇女的N-乙酰-β-D氨基葡萄糖苷酶(简称NAG酶)进行162个周期的观察,使用对硝基苯—N-乙酰-β-D氨基葡萄糖苷作底物与唾液中的NAG酶进行酶促反应。在一定条件下NAG酶作用于底物产生N-乙酰-β-D氨基葡萄糖和对硝基酚,再加一定量的碱溶液终止其酶反应,使对硝基酚呈黄色,然后进行比色,并以尿样LH(单克隆抗体酶免疫法)作为对照观察周期性变化。结果表明:在排卵前和排卵期NAG酶活性上升,通常在下次月经前13～17天之间。准确率90％与尿样LH对照符合率95％。

| Abstract: | N-Actyl-β-D-glucosamiwichast were observed in 123 women with normal menstrual cycles for 162 cycles. We have used LH as control , in studying cylical changes. The results showed that N-Acetyl-β-D-glu-cosaminidase activity increased 2~4 days before ovu-lation and menstruation. The first peak occurred between 13 -17 days before the next menstruation. The accuracy was 90%, level 95% was in accord with LH. |
