妊高征病人红细胞膜Ｎａ＋－Ｋ＋－ＡＴＰ酶活性０．３１±０．１１μｍｏｌｐｉ／ｍｇ蛋白·小时－１，膜内面Ｃａ结合量５０．００±１７．５０ｎｍｏｌ／ｍｇ蛋白，正常孕妇红细胞膜以上两项指标分别为０．４５±０．１３μｍｏｌｐｉ／ｍｇ蛋白·小时－１和６９．６±１９．１２ｎｍｏｌ／ｍｇ蛋白。将两组同一指标进行统计学分析，Ｐ均小于０．０１，具有显著性差异。提示妊高征时细胞膜钠泵功能和膜内面结合Ｃａ的能力减低，这些变化可能与妊高征高血压的发生和发展有一定关系。
PIH patients erythrocyte membrane Na + -K + -ATPase activity 0.31 ± 0.11μmolpi / mg protein · hr-1, the inner surface of the membrane Ca binding 50.00 ± 17.50nmol / mg protein, normal pregnant women with erythrocyte membrane above The two indicators were 0.45 ± 0.13 μmolpi / mg protein · hr-1 and 69.6 ± 19.12 nmol / mg protein, respectively. The two groups of the same indicators for statistical analysis, P were less than 0.01, with significant differences. It is suggested that the function of sodium pump in membrane and the ability of Ca (subscript Ca) in the membrane during pregnancy-induced hypertension are decreased. These changes may be related to the occurrence and development of hypertension in PIH.
