まとめ
馬の胃逆流 (GR) は,通常の小腸 (SI) 液よりもナトリウム濃度が低く,塩化物濃度が高くなります. これらの馬のSI流体とイオン損失を理解することは,イレウスの流体治療を助けます.
科学分野:
- 馬の内科
- 胃腸の生理学
- 比較生理学
背景:
- 小腸膨張 (SI) と胃逆流 (GR) は,イレウスを持つ馬に共通しています.
- 患者の水分と電解質のバランスに影響を与える.
研究 の 目的:
- 健康な馬のSIの液体容量を測定する.
- 通常のSI流体,GR流体,および切除中のSI流体におけるイオン濃度 (Na+,K+,Cl-) を測定し比較する.
- 通常のSI流体よりも,GR流体のNa+が低く,Cl-が高いという仮説を検証する.
主な方法:
- 水で2~15メートルのSIを膨らませる観察研究.
- SI容量を測定する.
- 健康な馬,GRの馬,SIの窒息した馬からのSI液中のイオン濃度の分析.
主要な成果:
- 通常のSI容量は2.8 ± 0.6L/mで測定された.
- 通常のSI液体Na+,K+,Cl-濃度はそれぞれ100±6,22±5,66±30mmol/ Lであった.
- 通常のSI液と比較して,GR液はNa+ (77 ± 16 mmol/ L) を著しく減らし,Cl- (96 ± 25 mmol/ L) を高めた. 全SI液体K+は血清K+の3〜5倍でした.
結論:
- 馬のGRは,通常のSI液と比較して明確な電解質変化によって特徴付けられます.
- 発見は,馬のSI障害における水とイオン損失を推定するための重要なデータを提供します.
- この情報は,イレウスの馬に有効な流体療法策を策定するのに不可欠です.

72.4K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Water functions as a solvent accommodating various solutes, which can be categorized under electrolytes and non-electrolytes. Non-electrolytes are usually held together by covalent bonds, restricting them from dissociating in solution, thereby leading to a lack of electrically charged components upon dissolving in water. They are predominantly organic molecules, such as glucose, creatinine, and urea. Electrolytes, on the other hand, are compounds that can break down into ions in water.

6.2K
The human body carefully regulates the internal pH of different organs to maintain homeostasis. For example, while the blood plasma maintains a neutral pH of 7, the stomach lumen has an acidic pH of 1.5 - 3.5. The low pH of stomach lumen helps kill pathogens in the food and break down complex food molecules.
The acid-secreting gastric mucosal epithelial cells (parietal cells) lining the stomach lumen maintain the low pH in the lumen. Numerous ion transporters and channels on these parietal...

Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...
