奶牛的低钾血症是一种严重的矿物质紊乱,可能危及生命,其特征是血清钾水平过低。本文利用非哺乳期和哺乳期奶牛钾平衡的动态数学模型,探讨了低钾血症的不同起源条件--钾摄入量减少、排泄量增加、酸碱失衡和胰岛素增加。这些模拟证实了文献中描述的观察结果。例如,它们表明,饮食摄入量或排泄量的变化对细胞内钾水平有很大影响,而细胞外钾水平只有很小的变化。模拟还表明,饮食中的钾含量越高,尿液中排出的钾就越多。数学模型的应用有助于实验计划,因此有助于3R战略:减少、改进和替换动物实验。
Hypokalemia in dairy cows, which is characterized by too low serum potassium levels, is a severe mineral disorder that can be life threatening. In this paper, we explore different originating conditions of hypokalemia—reduced potassium intake, increased excretion, acid-base disturbances, and increased insulin—by using a dynamic mathematical model for potassium balance in non-lactating and lactating cows. The simulations confirm observations described in literature. They illustrate, for example, that changes in dietary intake or excretion highly effect intracellular potassium levels, whereas extracellular levels vary only slightly. Simulations also show that the higher the potassium content in the diet, the more potassium is excreted with urine. Application of the mathematical model assists in experimental planning and therefore contributes to the 3R strategy: reduction, refinement and replacement of animal experiments.
