Abstract

Three-dimensional angioarchitecture oí the rats’ nasal septum was studied using corrosive resin cast technique and scanning electrón microscopy. The animáis were perfused with Mercox synthetic resin and subsequently, the specimens were treated with 20% NaOH solution íor several days at room temperature. They were washed in distilled water and dried at room temperature. The specimens were mounted on metal stubs, coaíed with gold and observed in the scanning electrón microscope. The results showed numerous main arteries running parallel to the base, arteriovenous anastomosis, and veins. The arteries and veins could be distinguished according to the nucleus’ morphology imprint of the endothelial cells on cast surfaces. It was also possible to observe characteristic elevations of venous valves on the surface of the venous plexus.
