We investigated the serum manganese (Mn) concentration of 52 children less than two years old. 22 of them were healthy controls (C), 13 had marasmatic (M) malnutrition and 17 kwashiorkor (K). The measurements of Mn were done in an atomic absorption spectrophotometer with a graft furnace oven. The serum was diluted with 1% triton X-100. For the quantification of Mn we used the addition method. There was a significant difference between the levels of Mn measured in the M group (1,582 +/- 0.673 micrograms/L), and the K group (1,811 +/- 0.700 micrograms/L) and levels obtained in the controls (3,212 +/- 1,247 micrograms/L). When we compared the concentration of Mn by sex or age in each group, we didn't find any significant difference. We conclude that the severe malnourished children in our study present lower concentrations of Mn as compared with controls.
我们调查了52名两岁以下儿童的血清锰（Mn）浓度。其中22名是健康对照（C），13名患有消瘦型（M）营养不良，17名患有夸希奥科病（K）。锰的测量在配有石墨炉的原子吸收分光光度计中进行。血清用1%的曲拉通X-100稀释。对于锰的定量，我们使用了标准加入法。在M组（1,582±0.673微克/升）、K组（1,811±0.700微克/升）和对照组（3,212±1,247微克/升）中测得的锰水平之间存在显著差异。当我们比较每组中按性别或年龄划分的锰浓度时，未发现任何显著差异。我们得出结论，与对照组相比，我们研究中的重度营养不良儿童锰浓度较低。
