まとめ
ポリフェノールサプリメントは,呼吸道炎症を軽減し,馬の喘息症候群 (EAS) の呼吸器の症状を改善しました. この研究は,この一般的な馬の呼吸器疾患の管理に有益な可能性があることを示唆しています.
科学分野:
- 獣医学
- 馬の呼吸器の健康
- 栄養免疫学
背景:
- 馬の喘息症候群 (EAS) は,成年馬の慢性炎症性呼吸器疾患である.
- 食中のポリフェノールは,ヒトの喘息において抗炎症的性質を示すが,馬の喘息における有効性は未調査のままである.
研究 の 目的:
- 健康な馬と喘息の馬の全身的および肺炎に対する混合ポリフェノールサプリメントの影響を評価する.
- 喘息の馬でポリフェノール補給を受けた後の ブロンコアルベオラ洗浄 (BAL) 細胞学と臨床呼吸器の徴候の変化を評価する.
主な方法:
- 第1部:18匹の馬 (8匹は健康で,10匹は喘息患者) が6~8週間毎日ポリフェノールサプリメントを摂取し,身体検査,BAL細胞検査,血清/BAL液体サイトカインの評価を行った.
- 第2部:喘息を患った10頭の馬をランダムに補給または対照群に配分し,その後は灰色のハインで誘発された呼吸道炎症,臨床症状と肺炎を評価した.
主要な成果:
- 栄養補給により,喘息の馬におけるBAL中性子とIL-6が著しく減少した (第1部).
- 喘息の馬は,健康な対照群と比較して,BAL IL-10のより大きな減少を示した.
- 補充された馬は,誘発性炎症 (第2部) の間,より少ない異常な再呼吸検査結果と低呼吸率を示した.
結論:
- ポリフェノールサプリメントは,馬の肺炎を調節する可能性がある.
- この結果は,ポリフェノールサプリメントが,特に環境管理戦略と統合された場合,軽度の喘息の馬の臨床症状を改善することを示唆しています.

Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

2.8K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:
