患病的新生儿小羊表现出氧化应激增加,由更高的活性氧物种 (ROS) 和氧化损伤生物标志物表明. 它们的抗氧化剂水平明显较低,这表明需要进行治疗考虑.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 生物化学 生化学
- 新生儿护理 新生儿护理
背景情况:
- 氧化损伤已知在败血症的人类,但其在小羊中的作用是研究不足的.
- 反应性氧物种 (ROS) 和抗氧化剂对于细胞损伤和防御机制至关重要.
研究的目的:
- 在新生儿小中量化ROS,氧化损伤生物标志物和抗氧化剂.
- 为了测试假设,患病的小比健康的小具有更高的ROS/氧化损伤标志物和更低的抗氧化剂.
主要方法:
- 一项前性队列研究,涉及72只住院和21只健康的新生小.
- 测量过氧化 (H2O2),麦隆地 (MDA),蛋白质碳基,超氧化失调酶 (SOD),催化酶 (CAT),谷,谷减少酶 (GR) 和谷过氧化酶 (GPx).
- 使用单向ANOVA与Tukey多重比较试验进行统计比较.
主要成果:
- 与健康的小马相比,患病的小马的H2O2,MDA和蛋白质碳基的度显著更高.
- 在患病的小马群中,CAT,谷氨,GR和GPx的度明显低于健康的小马群.
- 这些发现证实了在患病的新生儿小中氧化应激增加和抗氧化能力降低的假设.
结论:
- 患病和细菌性新生儿小经历了显著的氧化应激.
- 降低抗氧化剂度是新生小子疾病的关键特征.
- 这些氧化应激标志物和抗氧化剂水平需要在患病小的临床管理中加以考虑.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
