The relationship between age and blood magnesium (Mg) parameters has not been defined. Mg measurements in plasma, red blood cells (RBCs), and mononuclear blood cells (MBCs) were made in 104 normal volunteers (43 males and 61 females, ages 11-75 years). MBCs were separated from blood using a discontinuous Ficoll-Hypaque gradient. The mean values (+/- SEM) were as follows: plasma Mg 1.63 +/- 0.01 mEq/L, RBC Mg 4.55 +/- 0.06 mEq/L, MBC Mg content 72.8 +/- 1.0 fg/cell, and MBC Mg concentration 19.6 +/- 0.3 mEq/L. We compared these parameters with age (intervals of 10 years) using analysis of variance (ANOVA) and found no significant differences (p greater than 0.05). Thus, plasma, RBC, and MBC Mg parameters do not vary significantly between the ages of 11 and 75 years.
年龄与血镁（Mg）参数之间的关系尚未明确。对104名正常志愿者（43名男性和61名女性，年龄在11至75岁之间）进行了血浆、红细胞（RBC）和单核血细胞（MBC）中的镁含量测定。使用不连续的Ficoll-Hypaque梯度从血液中分离出MBC。平均值（±SEM）如下：血浆镁1.63±0.01mEq/L，红细胞镁4.55±0.06mEq/L，单核血细胞镁含量72.8±1.0fg/细胞，单核血细胞镁浓度19.6±0.3mEq/L。我们使用方差分析（ANOVA）将这些参数与年龄（以10年为间隔）进行比较，未发现显著差异（p大于0.05）。因此，在11至75岁之间，血浆、红细胞和单核血细胞的镁参数没有显著变化。
