测定１９例尿毒症患者的白细胞功能，结果显示白细胞粘附率、中性粒细胞吞噬率、杀菌率均显著低于正常对照组（Ｐ＜０．００１）。应用罗钙全［Ｒｏｃａｌｔｒｏｌ，１．２５（ＯＨ）２Ｄ３］４ｗ后，患者组白细胞粘附率、吞噬率、杀菌率比服药前显著升高（Ｐ＜０．００１），同时血钙水平亦比服药前明显升高（Ｐ＜０．０１）。提示罗钙全不仅能调节钙磷代谢，而且改善尿毒症患者白细胞功能。 The determination of leukocyte function in 19 patients with uremia showed that leukocyte adhesion rate, neutrophil phagocytosis rate and bactericidal rate were significantly lower than those in the normal control group (P <0.001). Compared with the pretreatment group, the leukocyte adhesion rate, phagocytosis rate and bactericidal rate were significantly increased (P <0.001), and the level of serum calcium was also higher than that of the control group before application of Rocaltrol (1.25 (OH) 2D3] Before taking medicine was significantly higher (P <0.01). Tip Luo calcium can not only regulate calcium and phosphorus metabolism, but also improve leukocyte function in patients with uremia.
