Abstract

Some trace elements are essential for the health of vertebrates, but little is known about their function, the amounts required, and the factors influencing their metabolism in tortoises. The aim of this study was therefore to measure trace elements (chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn)) in heparinized blood plasma of Hermann’s tortoises (Testudo hermanni) (n = 520) from March to September 2022 using inductively coupled plasma mass spectrometry (ICP-MS) and to establish specific reference intervals. Additionally, the influence of sex, season, and region of sample collection on the measured values were evaluated. Significant (p ≤ 0.05) sex-specific differences were found for Cu, Mg, and Mn; seasonal differences were found for Cr, Cu, Mn, Mo, and Se; and the region in which the tortoises were kept significantly impacted Cr, Cu, Fe, Mg, Mo, and Se levels. The results show that all of these factors should be consider when establishing and interpreting blood trace element levels in tortoises.

中欧赫尔曼陆龟（Testudo hermanni）体内按性别、季节和采样区域划分的微量元素含量

一些微量元素对脊椎动物的健康至关重要，但人们对它们的功能、所需数量以及影响陆龟新陈代谢的因素知之甚少。因此，本研究的目的是测量陆龟血浆中的微量元素（铬（Cr）、钴（Co）、铜（Cu）、铁（Fe）、镁（Mg）、锰（Mn）、钼（Mo）、硒（Se）和锌（Zn））、利用电感耦合等离子体质谱法（ICP-MS）对 2022 年 3 月至 9 月期间赫尔曼陆龟（Testudo hermanni）（n = 520）肝素化血浆中的锌（Zn）含量进行分析，并确定具体的参考区间。此外，还评估了性别、季节和样本采集地区对测量值的影响。结果发现，铜、镁和锰的性别差异显著（p ≤ 0.05）；铬、铜、锰、钼和硒的季节差异显著；龟的饲养地区对铬、铜、铁、镁、钼和硒的含量有显著影响。结果表明，在确定和解释陆龟血液中的微量元素水平时，应考虑所有这些因素。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
