Ultrastructural and morphometric aspects of ageing in the retinal capillaries of rats
Age-related morphological, ultrastructural and morphometric changes in the capillaries of the superficial and deep plexuses of the rat retina were studied in animals aged from 3 to 15 months. Our results suggest that ...
Differential vascular adaptive response to stress exposure in male and female rats: Role of gonadal hormones and endothelial cells
(Taylor & Francis Ltd, 2007-01-01)
Although there are reports concerning a vascular adaptive response to stress in males, this is not yet defined in females. The aim of this study was to delineate functional gender differences in the rat vascular adaptive ...
Ausência de arteriosclerose na porção intramiocárdica das artérias coronárias: Um mistério a ser resolvido?
Several studies show that portions of intramyocardial coronary arteries are spared of arteriosclerosis, involving morphological, embryological, biochemical and pathophysiological aspects. Endothelial function is significantly ...
Proliferation of the vascular endothelium of the iris following total debridement of the corneal epithelium and limbal excision of rabbits
Background Damage to the corneal epithelium causes not only a reaction for its repair but also affects other parts of the cornea as well as different components of the anterior segment of the eye. The purpose of this ...
Decreased endothelium-dependent vasoconstriction to noradrenaline in acute-stressed rats is potentiated by previous chronic stress: Nitric oxide involvement
(Elsevier B.V., 1998-01-01)
1. The objective was to determine whether nitric oxide participates in stress adaptive responses. Acute stress (AS) decreased endothelium-dependent vasoconstriction to noradrenaline (NA) in rat aorta [control rat (CR) ...
Differential vascular adaptive response in spontaneously hypertensive and Wistar rats: Role of nitric oxide, and prehypertensive and hypertensive states
(Elsevier B.V., 2006-07-10)
Stress-induced vascular adaptive response in SHR was investigated, focusing on the endothelium. Noradrenaline responses were studied in intact and denuded aortas from 6-week-old (prehypertensive) and 14-week-old (hypertensive) ...
Effects of diethylpropion treatment and withdrawal on aorta reactivity, endothelial factors and rat behavior
(Elsevier B.V., 2003-07-15)
Diethylpropion (DEP) is an amphetamine-like compound used as a coadjutant in the treatment of obesity and which presents toxicological importance as a drug of abuse. This drug causes important behavioral and cardiovascular ...
Venous endothelium reactivity to Angiotensin II: A study in primary endothelial cultures of rat vena cava and portal vein
(Elsevier Inc, 2018)
The role of the vascular endothelium in modulating the arterial system has been widely investigated, but poorly explored at the venous site. In the present work, primary cultures of venous endothelium from rat Vena Cava ...
