概括

血清总的测量对于在生病的成年牛中评估血液电离是不可靠的. 血中化物和水平也会影响电离,影响诊断.

科学领域:

兽医医学兽医医学兽医医学
动物生理学动物生理学
临床病理学临床病理学

背景情况:

有限的数据存在影响血液电离 (ciCa2+) 的因素在生病的成年牛.
在这种人群中,血清总 (ctCa) 检测异常ciCa2+的诊断准确性尚未得到充分确立.

研究的目的:

评估ciCa2+与静脉血液pH值,血中化物 (cCl), (cNa) 和 (cK) 度之间的关联.
评估ciCa2+与ctCa的关系,疾病成年牛的总蛋白质,白蛋白和球蛋白度.
确定ctCa的诊断性能 (灵敏度和特异性),以识别异常ciCa2+.

主要方法:

这是一项前性研究,涉及265头患有各种疾病的成年牛.
测量包括全血pH,ciCa2+,cNa,cK,cCl,ctCa,总蛋白质和白蛋白.
统计分析调查了变量之间的关系,并计算了ctCa的诊断准确性.

主要成果:

血清总 (ctCa) 对检测异常ciCa2+的敏感度为66.0%,特异性为72.3%.
ctCa测量解释了调整后血液电离 (iCa2+7.40) 的42%.
血化物 (cCl) 和 (cK) 分别解释了额外的21%和9%的差异.

结论:

血清总 (ctCa) 的测量不足以准确地预测患病成年牛的血液电离 (ciCa2+) 状态.
血清总度和血化物 (cCl) 被确定为该队列中ciCa2+最重要的预测因素.

关键词:

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Feedback Regulation of Calcium Concentration

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

EDTA: Direct, Back-, and Displacement Titration

EDTA: Direct, Back-, and Displacement Titration

The EDTA titration types for metal ion analysis include direct titration, back-titration, and replacement titration.
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...
