氯化钠的应用:
※ 氯化钠是细胞外液的主要阳离子,主要用于控制水的分布,和应用于体液平衡和体液的渗透压。在调节体液的酸碱平衡中,氯化钠与氯化物和碳酸氢盐有关,氯是主要的细胞外阴离子,紧紧跟随钠的代谢,氯离子浓度的变化反映了人体酸碱平衡的变化;
※ 当体内能量耗尽时,必须补充钠以维持细胞内渗透压,神经传导,肌肉收缩以及保证正常的肾功能;
※ 氯化钠可以配置缓冲盐溶液;
※ 氯化钠可以作为消毒杀菌剂使用;
※ 氯化钠在工业或者实验过程中可以作为中间体或者原料产生企业化学物质。

| Application3 |
Sodium, the major cation of the extracellular fluid, functions primarily in the control of water distribution, fluid balance, and osmotic pressure of body fluids. Sodium is also associated with chloride and bicarbonate in the regulation of the acid-base equilibrium of body fluid. Chloride, the major extracellular anion, closely follows the metabolism of sodium, and changes in the acid-base balance of the body are reflected by changes in the chloride concentration.功能
氯化钠的功能:
钠(Na +)和氯离子(Cl-)是细胞外区室的主要离子,包括血浆,间质液(细胞之间的流体)和跨细胞液(例如脑脊髓液,关节液)。因此,它们在许多生命维持过程中发挥着关键作用。
氯化钠维持膜电位:
钠和氯化物是电解质,有助于维持整个细胞膜的浓度和电荷差异。钾(K +)是细胞内主要的带正电的离子(阳离子),而钠是细胞外液中的主要阳离子。内部钾浓度比外部细胞高约30倍,而内部钠浓度则比外部细胞低10倍以上。跨细胞膜的钾和钠之间的浓度差会产生电化学梯度,称为膜电位。细胞膜电位通过细胞膜中的离子泵(尤其是Na + / K + ATPase泵)保持。这些泵使用ATP(能量)将钠泵出细胞,以换取钾(图1)。据估计,他们的活动占典型成年人静息能量消耗的20%-40%。专用于维持钠/钾浓度梯度的大部分能量强调了该功能在维持生命中的重要性。严格控制细胞膜电位对于神经冲动传递,肌肉收缩和心脏功能至关重要(2-4)。

Controversy persists regarding the appropriate treatment of acute alkali injury to the esophagus. The current study establishes a controlled model of alkali esophageal injury and examines the efficacy of saline dilution therapy. Esophagi were harvested from 60 Sprague Dawley rats. Each end was cannulated with a 20 gauge catheter. Specimens were maintained in an oxygen perfused saline bath (37 °C) during a 60 min experimental period and then fixed immediately in 10% formalin solution for histologic examination. Three experimental groups (A, B, and C) were perfused with 50% sodium hydroxide solution at time zero. Treatment with saline perfusion was performed immediately in group A, five min after injury in group B, and 30 min after injury in group C. The positive control group D was perfused with saline at time zero. A negative control, group E, was perfused with 50% sodium hydroxide at time zero. This group did not receive subsequent treatment with saline. Pathologic examination was performed in a blinded fashion using a score of 0 to 3 (0, no injury; 1, minimal 2, moderate; 3, severe) for seven histologic criteria: epithelial viability, extent of injury, cornified epithelial cell differentiation, granular cell differentiation, epithelial cell nuclei, muscle cells, and muscle cell nuclei. The positive control group demonstrated scores of zero. Nonparametric analysis showed a significant difference among treatment groups for each injury category. Trend analysis revealed a significant progression of injury for each category associated with time to treatment. Discriminant analysis indicated that the muscle cells category was the most useful category with which to distinguish injury among groups. In conclusion, saline lavage decreased objective evidence of esophageal injury after a severe alkaline exposure, and early therapy enhanced this beneficial effect.
