人与大鼠肝门部胆管壁胶原纤维构筑形态的研究

目的 探讨人与大鼠肝门部胆管壁胶原纤维构筑形态的差异.方法 通过对人与大鼠正常和扩张肝门部胆管壁胶原纤维Masson三色染色,观察人与大鼠胆管纵向与横向切面胶原纤维构筑形态和在应力作用下变化特征.结果 人与大鼠的肝门部胆管壁胶原纤维的构筑形念相似,主要分布在胆管壁的中、外层,胶原纤维束旱波浪状平行排列,之间有分支相连,并与胆管纵轴方向一致.结论 人与大鼠肝外胆管壁胶原纤维构筑形态的相似性,使其解剖结构与功能相适应.

Anatomical comparison of morphology and structure of collagen fiber of the hilar bile duct between human and rat

Objective To explore the differences in morphology and structure of collagen fiber of the hilar bile duct between human and rat. Methods The morphology and structure of vertical and horizontal cross-section of human and rat collagen fiber of the normal and dilated hilar bile duct, and their changes under stress were observed after Masson trichrome staining. Results The morphology and structure of collagen fiber of hilar bile duet in human was similar to that in rat. The collagen fiber mainly distributed in the middle and outer layer of the hilar bile duct. The wave-like collagen fiber bundles were arranged in parallel, consistent with the longitudinal axis direction of the bile duct, and connected by the small branches. Conclusions The morphology and structure of collagen fiber of the hilar bile duct in human is similar to that in rat. The anatomical structure of the collagen fiber is adapted to its function.
