狗股动脉吻接后顺应性变化的形态学基础

目的：探讨动脉吻接后形态学变化、结构成分含量与顺应性变化之间的关系。方法：取术后１天、３天、７天、１４天、３０天、７５天吻合口动脉段，切片分别用ＨＥ，Ｗｅｉｇｅｒｔ，Ａｎｉｌｉｎｅ ｂｌｕｅ，Ｎｅｕｂｅｒｔ法染色，光科像珞结构成分相对含量。结果：术后１４天，吻合口已基本疤痕化，各时相点弹性纤维含量变化无显著性差异，胶原纤维含量呈增加之趋势，Ｃ／Ｅ值术后逐日增高，第１４天最高，结论：血和过程，结构成

MORPHOLOGICAL BASIS OF CHANGES OF COMPLIANCE IN ANASTOMOSED CANINE FEMORAL ARTERIES

To explore the relation between the morphologial changes, contents of structural components and changes of compliance in anastomosed arteries. Methods: The slices of anastomosed arterial segments recovered after 1, 3, 5, 7, 14, 30, 75 days were stained respectively with H. E. Weigert, Aniline blue, and Neubert methods and observed under the light microscope. The relative contents of elastin, collagen and smooth muscles were measured by image analysis system. Results: 14 dyas later, the anastomotic site scarred. There were no significant changes in the contents of elastin at different time intervals, while the collagen increased gradually. C/E value also increased day by day and reached the highest at 14th day. Conclusion: here.covering process and the changes of the contents of structural components of the anastomosed tenes were relate to the changes of compliance.
