科学领域:

  • 肺部医学 肺部医学
  • 发展生物学 发展生物学
  • 营养科学 营养科学

背景情况:

  • 众所周知,营养不足会对支气管肺功能失调的发展产生负面影响.
  • 关联营养与肺部结果以及最佳营养策略的机制尚不清楚.

研究的目的:

  • 研究产后营养对肺部结构和功能的孤立影响.
  • 评估产后生长限制 (PGR) 如何影响小鼠模型中的肺部发育,介质和脂肪酸概况.

主要方法:

  • 鼠被交叉培养,以创建控制 (垃圾大小8) 和PGR (垃圾大小16) 组.
  • 肺部结构,功能,血清和肺组织脂肪酸以及分子媒介被分析在出生后的第21天.

主要成果:

  • 在两性中,PGR导致空气壁较厚,肺部服从性降低,组织缩增加.
  • 雄性大鼠表现出增加的肺弹性,弹性蛋白,溶醇氧化酶和弹性纤维沉积.
  • 雌性大鼠的呼吸道阻力增加,肺组织中的多可萨赫酸水平降低.

结论:

  • 产后生长限制会损害雄性和雌性大鼠的肺部结构和功能.
  • 在PGR之后,观察到肺部发育分子媒介的性别特异性变化.
