采用新极谱法测定枣庄市食用和未食用富硒苹果后的健康居民的全血含硒量。其中食用富硒苹果的居民 56例 ,未食用富硒苹果居民 2 94例 ,全血硒含量分别为 1 1 9.1± 51 .0 μg/L和99.7± 53.9μg/L。食用富硒苹果后的居民中男性 2 4例 ,女性 32例 ,全血硒含量分别为 1 2 3.0± 61 .3μg/L和 1 1 6.2± 43.5μg/L,未食用富硒苹果居民中男性 1 53例 ,女性 1 41例 ,全血硒含量分别为 1 0 0 .1± 54.2 μg/L和 99.3± 54.0 μg/L。实验结果表明 ,食用富硒苹果后的枣庄市居民血硒水平处于临床营养状态 ,富硒苹果可提高人体全血硒水平 ,且食用与未食用富硒苹果居民血硒水平存在显著性差异 (P<0 .0 1 )
Determination of whole blood selenium content of healthy residents after eating and not eating selenium-rich apples in Zaozhuang City by using new polarographic method. Among them, 56 residents inhabit selenium-rich apples and 2 94 residents who did not consume selenium-enriched apples. The selenium contents in whole blood were 11.19 ± 51.0 μg / L and 99.7 ± 53.9 μg / L, respectively. Among 24 residents and 32 women, the content of selenium in whole blood was 122.0 ± 61.3μg / L and 11.2 ± 43.5μg / L, respectively, and the percentage of non-selenium-enriched apple inhabitants 153 cases, 141 cases of female, the selenium content of whole blood were 100.1 ± 54.2 μg / L and 99.3 ± 54.0 μg / L, respectively. The results showed that the blood selenium level of residents in Zaozhuang City after eating Se-enriched apple was in a state of clinical nutrition. Se-enriched apple could increase the level of selenium in human whole blood, and there was a significant difference in selenium level between residents and non-selenium-rich apples (P <0 .0 1)
