Description
Summary:Vascular endothelium play an essential role in regulating endothelial functions by maintaining normal vascular tone, modulating hemostasis, and preventing thromobogenesis. The aim of present study was to reveal ultrastructure features of coronary artery endothelium in Bactrian Camels by means of scanning electron microscope (SEM) technology. The results showed that the endothelial cells distribute along the direction of blood flow. Their morphology and protuberant degree towards luminal surface vary for different parts of the coronary artery. The luminal surface of a.c oronaria sinistra and a. coronaria dextra was covered by impaired and intact endothelium, respectively. Platelets and leukocytes sticking to the endothelium were found. KEY WORDS: Endothelial cells; Bactrian Camel; Coronary artery; Ultrastructure. Las celulas endoteliales de los vasos sanguineos juegan un rol esencial en la regulacion de las funciones endoteliales manteniendo el tono vascular, modulando la homeostasis y previniendo la trombogenesis. En la investigacion se utilizo un microscopio electronico de barrido, revelando las caracteristicas estructurales de las celulas endoteliales de los vasos coronarios de los camellos bactrianos. Los resultados indican que las celulas endoteliales estaban distribuidas a lo largo de la direccion de flujo. En distintas partes de la arteria coronaria existen diferencias en el grado de proyeccion de la morfologia y de la superficie de la cavidad de dichas celulas. La superficie luminal de la arteria coronaria izquierda y la arteria coronaria derecha estaban cubiertas por endotelio deteriorado e intacto, respectivamente. Se observo adhesion de leucocitos y plaquetas en la superficie de las celulas endoteliales. PALABRAS CLAVE: Celulas endoteliales; Camello bactriano; Arteria coronaria; Ultraestructura.
