接续上一篇论文 (10) 的内容，本研究的目的是进一步详细检查 180 名表面健康的委内瑞拉婴儿（96 名男孩和 84 名女孩）的血清锰浓度，年龄从 5 天到 12 个月不等，他们都是梅里达居民。采用流动注射分析-原子吸收分光光度法测定锰。血清锰的平均值为0.42+/-0.12、0.41+/-0.11、0.39+/-0.13、0.39+/-.1、0.38+/-0.09。 5天和1、3、5、7、10、11和12个月大的婴儿分别为0.37+/-0.11、0.36+/-0.12和0.29+/-0.10μg/L。这些值表明，血清中锰的平均浓度随着年龄的增长而降低，但所涉及的机制尚不清楚，降低的后果也不清楚。统计分析未显示性别对5天至12个月年龄范围内金属血清值有任何显着影响。
Taking up where a previous paper had left off (10) the purpose of this study was to examine in further detail the serum concentration of manganese of 180 apparently healthy Venezuelan infants (96 boys and 84 girls) ranging from 5 days to 12 months old, all residents of Merida. The flow injection analysis-atomic absorption spectrophotometric technique was used for the determination of manganese. The mean values of serum manganese were 0.42+/-0.12, 0.41+/-0.11, 0.39+/-0.13, 0.39+/-.1, 0.38+/-0.09. 0.37+/-0.11, 0.36+/-0.12 and 0.29+/-0.10 mu g/L in infants 5 days and 1,3,5,7,10,11 and 12 months old, respectively. These values indicate that the average concentration of manganese in serum decreases with age, but the mechanism involved is not yet known, nor are the consequences of the decrease. The statistical analysis did not show any significant influence of sex on the serum value of the metal in the age range of 5 days to 12 months.
