| Summary: | The spontaneously hypertensive rat (SHR) has been well established as a suitable model for hypertension
research, but little is known about the morphology of hypertensive vascular remodeling in this model. The
present study was designed to investigate the structural changes of blood vessels in 6 months aged SHR in
comparison to their corresponding model, Wistar Kyoto rats (WKY). The study utilised 12 male rats; which
were equally divided into 6 SHR and 6 WKY. During dissection, thoracic aorta was harvested for histological
examination. To evaluate the morphological appearance of SHR and WKY, hematoxylin and eosin (H&E)
stain was done. Whereas Scanning electron microscopy was applied to view the ultrastructure of the vessel.
The result shows that the aorta histology of WKY looks normal; depicted by showing smooth intima with a
single layer of endothelial cells. In contrast with SHR, the structure was slightly distorted and thicker intima
observed; suggesting vascular remodeling has occurred. |
