Forty fetuses had uncompleted tracheal ring and 12 had variable degrees of tracheal stenosis related the vascular rings .

57只先天性膈疝胎鼠中，40只有不完全的气管软环，12只有程度不等的 气管狭窄，并与异常的血管 环相关。

Forty-eight hours later the tracheal rings were entirely covered by pseudostratified ciliated columnar epithelium .

48h后， 气管 环全部由假复层纤毛柱状上皮细胞覆盖。

Experiments of Tracheal Reconstruction Using Porous Titanium Rings and Free Skin Flaps ; Spiral CT and multiplanar reconstruction techniques for the diagnosis of children with atypical bronchial foreign body

带孔 钛环外支撑游离皮片重建 气管 缺损 的 动物实验螺旋CT及多平面重建技术在小儿不典型支气管异物的诊断价值

Six hours after removal of 5-FU the tracheal rings were covered with flattened epithelium .

去除 5-FU6h后，由扁平上皮覆盖；

Methods : By measuring the force of guinea pig isolated tracheal rings we observed both relaxing effect of Sco and interactions between Sco and histamine ( His ) acetylcholine ( Ach ) or propranolol ( Pro ) on isolated TSM .

方法：制备豚鼠离 体气 管 环标本，通过测定其张力变化，观察Sco对离体 气管 平滑肌的舒张作用及与组胺（His）、乙酰胆碱（Ach）、普萘洛尔（Pro）之间的相互作用。

Objective To investigate the feasibility and efficacy of the cervical tracheal reconstruction using porous titanium rings and free skin flaps .

结论 带孔 钛环可重建 气管 支架，游离皮片可作为 气管 粘膜 替代 物，是 气管 重建的简便方法。
