据报告脱氧胞核苷酸脱氨酶(dCMP脱氨酶)是先兆子痫的一个敏感的指标,在高血压发生前血清dCMP脱氨酶活性即增强,且其活性强弱与先兆子痫的严重程度相一致.但此酶相当不稳定且须镁离子激活,测定方法也较复杂,故在大规模使用时有一定困难.本文推荐以测定血清胞嘧啶核苷酸脱氨酶代替dCMP脱氨酶.作者测定了30名正常成年男性及30名非孕成年妇女的胞嘧啶核苷酸脱氨酶活性,分别为2.7±0.6单位和2.7±0.65单位.此外,对1,305名正常孕妇血清胞嘧啶核苷酸脱氨酶和血清dCMP脱氨酶活性
Deoxy-nucleotides deaminase (dCMP-deaminase) is reported to be a sensitive indicator of preeclampsia and serum dCMP deaminase activity is elevated prior to hypertension and its activity is correlated with preeclampsia But this enzyme is quite unstable and must be activated by magnesium ions, the determination of the method is also more complex, so there are some difficulties in the large-scale use of this paper recommended to measure serum cytosine deaminase in place of dCMP deamination The authors measured cytosine deaminase activity in 30 normal adult men and 30 non-pregnant adult women at 2.7 ± 0.6 units and 2.7 ± 0.65 units, respectively. In addition, 1,305 normal pregnant women with serum cytosine Nucleotide deaminase and serum dCMP deaminase activity
