Summary

Introduction. It has been generally accepted that female hormones protect against the development of cardiovascular diseases and more especially with regard to the development of degenerative disorders affecting the arteries. Aims. This study attempts to show the relationships between the hormonal component and the artery wall, and evaluates them from a histological and morphometric point of view. Materials and methods. We conducted an experimental study in rats using different groups of animals in order to provide an animal model in which to demonstrate the arterial repercussions of the different hormonal situations. The experimental design was structured in a number of study groups based on hormonal deprivation, followed by replacement that was implemented either pharmacologically or by means of ovarian transplant in the wall of the artery. Results and conclusions. The repercussions of hormone deprivation were not seen very clearly, but detection was possible using morphometric methods. Results show that hormone replacement neutralises the possible degenerative effects stemming from hormone deprivation. We discuss the interaction of estrogenic hormones and their involvement in the development of arterial pathologies, and the evidence that exists in the literature on this issue.

Resumen

Introducción. Se ha considerado de una forma generalizada que las hormonas femeninas protegen el desarrollo de enfermedades cardiovasculares y muy especialmente el desarrollo de las alteraciones degenerativas de las arterias. Objetivo. El estudio trata de evidenciar las relaciones que el componente hormonal tiene sobre la pared arterial, valoradas desde el punto de vista histológico y morfométrico. Materiales y métodos. Se realiza un trabajo experimental en la rata con la utilización de diferentes grupos de animales, soportado el estudio en un modelo animal para evidenciar las repercusiones arterialmente de las diferentes situaciones hormonales. El diseño experimental se estructura en diferentes grupos de estudio sobre la base de una deprivación hormonal, posterior suplencia, ya sea farmacológica o a través del trasplante ovárico sobre la pared arterial. Resultados y conclusiones. Las repercusiones de la deprivación hormonal no han sido muy evidentes, pero sí detecta-bles mediante métodos morfométricos. Los resultados demuestran que la suplencia hormonal neutraliza los posibles efectos degenerativos derivados de la deprivación hormonal. Se discute la interacción de las hormonas estrogénicas y su implicación en el desarrollo de patología arterial y las evidencias existentes al respecto, bibliográficamente.

Introdução.

Objectivo. O estudo trata de evidenciar as relações que a componente hormonal tem sobre a parede arterial, avaliadas sob o ponto de vista histológico e morfométrico. Materiais e métodos. Foi realizado um trabalho experimental no rato com a utilização de diferentes grupos de animais, baseando o estudo num modelo animal para evidenciar as repercussões arteriais das diferentes situações hormonais. O desenho experimental é estruturado em diferentes grupos de estudo sobre a base de uma privação hormonal, posterior suplemento, quer seja farmacológico ou através do transplante ovárico sobre a parede arterial. Resultados e conclusões. As re-percussoes da privagao hormonal foram muito evidentes, mas igualmente detectáveis mediante métodos morfométricos. Os resultados demonstram que o suplemento hormonal neutraliza os possíveis efeitos degenerativos derivados da privação hormonal. É discutida a interacgao das hormonas estrogénicas e a sua implicagao no desenvolvimento da patologia arterial e as evidencias existentes no que diz respeito á bibliografia.
