维生素A和锌是与泰国东北部人群受疾病折磨相关联的微量营养素。对泰国东北部23～75岁间的健康人群血清维生素A和锌的浓度进行研究。通过高效液相色谱法分析维生素A,通过火焰原子吸收光谱分析技术测定锌。研究结果显示,人群血清维生素A的平均水平为2.30μmol/L。男性维生素A水平明显高于女性。女性维生素A的水平具有随年龄增长而显著升高的趋势,而在所研究的各年龄阶段男性中其水平相对稳定。人群血清锌的平均水平是18.20μmol/L。男性和女性间锌水平没有显著性差异。锌水平具有随年龄增长而显著降低的趋势,特别是在男性人群中。研究认为,研究结果为泰国东北部健康人群的血清维生素A和锌水平提供了基线数据。
Vitamin A and zinc are micronutrients associated with disease affliction in northeastern Thailand. The concentrations of serum vitamin A and zinc in healthy population of 23-75 years old in northeastern Thailand were studied. Vitamin A was analyzed by high performance liquid chromatography and zinc was determined by flame atomic absorption spectrometry. The results show that the average level of serum vitamin A in the population is 2.30μmol / L. Male vitamin A levels were significantly higher than women. The level of vitamin A in women tends to increase significantly with age, whereas the level of vitamin A in women of all ages studied is relatively stable. The average serum zinc level is 18.20μmol / L. There was no significant difference in zinc levels between men and women. Zinc levels have a marked downward trend with age, especially in the male population. The study concluded that the results provide baseline data for serum vitamin A and zinc levels in healthy populations in northeastern Thailand.
