Balloon-injured rabbit artery

球囊导管损伤兔髂动脉或颈动脉内皮后,在保留高胆固醇饲料的条件下可加速损伤部位的内膜增厚和动脉粥样硬化样病变,常用于研究内皮损伤后的修复和平滑肌细胞迁移。

Outcome measures

获得可用于兔主动脉斑块组织学分级和组成的 HE 染色切片。

Experimental animals

动脉组织石蜡切片 H&E 染色
Age
not reported in the cited source
Tissue
aortic root; thoracic aorta

Experimental procedures

H&E staining **Dewaxing:** Paraffin sections are placed in xylene for 3 x 00:03:00 H&E staining **Rehydration: ** Paraffin sections are placed in - 100% EtOH for 3 x 00:03:00 - 95% EtOH for 1 x 00:03:00 - Rinse with water H&E staining **Hematoxylin staining: ** Paraffin sections are stained with hematoxylin for 00:00:20 and rinse under running water for 00:01:00 H&E staining **Differentiation and bluing:** Paraffin sections are placed into the bluing reagent for 00:01:00 and rinse under running water for 00:01:00 _This step results in a blue coloration of the nuclei._ H&E staining **Eosin staining:** Parrafin sections are counterstained with Eosin for 00:00:10 _This step results in a pink coloration of the cytoplasmic components and connective tissue fibers._ H&E staining **Dehydration and Clearing:** Paraffin sections are placed in - 95% EtOH for 00:02:00 - 100% EtOH for 2 x 00:02:00 - Xylene for 2 x 00:02:00 H&E staining **Mounting:** Parrafin sections are mounted with a glass coverslip using Permount.

Model identity

Model name
Balloon-injured rabbit artery
Species
rabbit

Biological characteristics

Phenotype stage
损伤后数周出现内膜增厚,合并高胆固醇饲料时病变加速。
Research questions
内皮损伤后内膜增生和平滑肌细胞迁移机制;损伤加速动脉粥样硬化的实验设计。
Limitations
机械损伤本身不是自发性动脉粥样硬化,病变机制以损伤后修复和内膜增生为主;手术操作和损伤程度影响结果,不能直接等同于人类斑块形成。
