Abstract Using the previously developed rabbit model of perioperative dry eye syndrome (PDES) and quantitative mass spectrometric technique it is shown that the development of corneal erosion under conditions of general anesthesia is associated with changes in the content of inflammatory metabolites, namely, derivatives of linoleic (LA), alpha-linolenic (ALA), and arachidonic (AA) acids in tear fluid. The increase in the content of the metabolites of LA and ALA is found to be the most significant, while the content of AA derivatives (with the exception of 12-HETE) remains almost unchanged, indicating the key roles of the LA and ALA cascades in the inflammatory response in PDES. The increase in the concentration of oxylipins that can be formed by nonenzymatic oxidation of LA (9-KODE) or its processing by cytochromes (12,13-EpOME) under oxidative conditions indicates a significant contribution of oxidative stress to the development of PDES. The majority of metabolites of LA (13-HODE and 9-HODE), ALA (9-HOTrE and 13-HOTrE) and AA (12-HETE), the tear content of which was changed in PDES, are generated by the enzymes of lipoxygenase family. By contrast, the concentration of cyclooxygenase products does not exhibit any significant fluctuations. These data suggest a low therapeutic potential of cyclooxygenase inhibitors (such as nonsteroidal anti-inflammatory drugs) and a high therapeutic potential of antioxidants and lipoxygenase inhibitors in PDES, which should be taken into account upon developing a complex therapy for this disease.

与围手术期干眼症相关的炎性奥昔利品泪液含量的变化

摘要 使用先前开发的围手术期干眼症 (PDES) 兔模型和定量质谱技术表明,全身麻醉条件下角膜侵蚀的发展与炎症代谢物,即亚油酸衍生物的含量变化有关。 (LA)、α-亚麻酸 (ALA) 和泪液中的花生四烯酸 (AA)。发现 LA 和 ALA 代谢物含量的增加最为显着,而 AA 衍生物(12-HETE 除外)的含量几乎保持不变,表明 LA 和 ALA 级联在PDES 中的炎症反应。通过 LA (9-KODE) 的非酶促氧化或其由细胞色素加工形成的 oxylipins 浓度增加 (12, 13-EpOME) 在氧化条件下表明氧化应激对 PDES 的发展有显着贡献。LA(13-HODE 和 9-HODE)、ALA(9-HOTrE 和 13-HOTrE)和 AA(12-HETE)的大部分代谢物(其泪液含量在 PDES 中发生变化)是由以下酶产生的:脂氧合酶家族。相比之下,环氧合酶产物的浓度没有表现出任何显着的波动。这些数据表明环加氧酶抑制剂(如非甾体抗炎药)的低治疗潜力和抗氧化剂和脂氧合酶抑制剂在 PDES 中的高治疗潜力,在开发针对该疾病的复杂疗法时应考虑到这一点。LA(13-HODE 和 9-HODE)、ALA(9-HOTrE 和 13-HOTrE)和 AA(12-HETE)的大部分代谢物(其泪液含量在 PDES 中发生变化)是由以下酶产生的:脂氧合酶家族。相比之下,环氧合酶产物的浓度没有表现出任何显着的波动。这些数据表明环加氧酶抑制剂(如非甾体抗炎药)的低治疗潜力和抗氧化剂和脂氧合酶抑制剂在 PDES 中的高治疗潜力,在开发针对该疾病的复杂疗法时应考虑到这一点。LA(13-HODE 和 9-HODE)、ALA(9-HOTrE 和 13-HOTrE)和 AA(12-HETE)的大部分代谢物(其泪液含量在 PDES 中发生变化)是由以下酶产生的:脂氧合酶家族。相比之下,环氧合酶产物的浓度没有表现出任何显着的波动。这些数据表明环加氧酶抑制剂(如非甾体抗炎药)的低治疗潜力和抗氧化剂和脂氧合酶抑制剂在 PDES 中的高治疗潜力,在开发针对该疾病的复杂疗法时应考虑到这一点。环氧合酶产物的浓度没有表现出任何明显的波动。这些数据表明环加氧酶抑制剂(如非甾体抗炎药)的低治疗潜力和抗氧化剂和脂氧合酶抑制剂在 PDES 中的高治疗潜力,在开发针对该疾病的复杂疗法时应考虑到这一点。环氧合酶产物的浓度没有表现出任何明显的波动。这些数据表明环加氧酶抑制剂(如非甾体抗炎药)的低治疗潜力和抗氧化剂和脂氧合酶抑制剂在 PDES 中的高治疗潜力,在开发针对该疾病的复杂疗法时应考虑到这一点。
