摘要
研究目的探讨血红蛋白（Hb）和红细胞原卟啉（EP）水平与海拔高度的关系研究方法青海省贵南县及玛多县海拔高度分别为3200米和4300米。选该两县7岁～14岁在校健康中小学学生各122人，用滤纸片高铁氰化法检测血红蛋白，用滤纸片荧光分光光度计法检测红细胞原卟啉，用t检验和配对t检验进行统计学处理。结果贵南县和玛多县7岁～14岁建康儿童Hb分别为133．6±10．1，152．8±14．0g／L（t＝12．31，P＜0．001），EP分别为320．7±114．9，347．8±123．6μg／L（t＝1．77，P＞0．05），EP／Hb分别为2．4±0．9，2．3±0．8（t＝1．12，P＞0．05）。配对t检验显示，Hb、EP、EP／Hb男女之间无显著性差异（P＞0．05）结论随海拔高度增加，7岁～14岁儿童Hb及EP水平显著升高，无性别差异。
Objective To ssarch for the relationship between hemoglobulin (Hb),erythrocyte protoporphyrin (EP) and the altitude.Methods The altitudes of Guinan and Maduo county in Qinghai province are respectively 3200m and 4300m. The 122 healthy students aged from 7 to 14 years old were selected, Hb and EP of them were respectively determined by the methods of ferric cyanation and fluorospectrophotometry. The statistical treatment was carry out by t test and matched-pair t test.Results The Hb levels of the healthy children aged from 7 to 14 years old in Guinan and Maduo county are respectively 133 .6±10.1 and 152.8±14.0 g/L (t = 12.31, p＜0.001), the EP levels of them are respectively 320.7 ± 114.9 and 347.8 ± 123.6 μg/L (t = 1.77, P＞0.05), the value of EP/Hh of them are respectively 2.4 ±0 .9 and 2 .3±0.8 (t = 1.12, p＞0.05). The result of matched-pair t test shows that there are not sexural difFerence for Hb, EP and EP/Hb (P＞0.05).Conclusion Along with the increasing of altitude, the Hb and EP levels of the healthy Children aged from 7 to 14 years old are obviously increased and on sexural difference.
