Vitamin E suppresses aortic ultrastructural alterations induced by toxic doses of monosodium glutamate

Int. j. morphol; 40 (3), 2022
SUMMARY: An association between certain food additives and chronic diseases is reported. Current study determined whether administering toxic doses of the food additive monosodium glutamate (MSG) into rats can induce aortopathy in association with the oxidative stress and inflammatory biomarkers upregula...

Are statins a risk factor in patients with atherosclerosis?

Int. j. morphol; 40 (5), 2022
SUMMARY: Statins inhibit cholesterol synthesis, but also have other pleiotropic effects. There are indications that they affect macrophage survival trough the regulation of apoptosis. We analyzed 50 samples of aortic wall, selected based on statins in patients' therapy (n=25, Th-S group) or statin-free t...

IInvestigation of possible oxidative damage caused by formaldehyde exposure in the rat's heart and aorta tissue

Int. j. morphol; 39 (4), 2021
SUMMARY: Formaldehyde (FA) is a toxic substance used frequently in the field of medicine as well as in many industrial areas. Especially people working in the field of anatomy, histology, and pathology are in high risk group because of the use of the FA. Studies showing the effects of FA on the cardiovas...

Vanadium inhibits Type 2 diabetes mellitus-induced aortic ultrastructural alterations associated with the Inhibition of dyslipidemia and biomarkers of inflammation in rats

Int. j. morphol; 38 (1), 2020
The potential inhibitory effect of the insulin mimicking agent, vanadium on type 2 diabetes mellitus (T2DM)induced alterations to the aorta ultrastructure associated with the suppression of dyslipedima and biomarkers of inflammation has not been investigated before. Therefore, we tested whether vanadium ...

Possible mechanisms involved in the effect of the subchronic administration of rosuvastatin on endothelial function in rats with metabolic syndrome

Braz. j. med. biol. res; 53 (2), 2020
Metabolic syndrome is a multifaceted condition associated with a greater risk of various disorders (e.g., diabetes and heart disease). In a rat model of metabolic syndrome, an acute in vitro application of rosuvastatin causes relaxation of aortic rings. Since the outcome of a subchronic rosuvastatin trea...

Evaluation of smooth muscle relaxant potential of Bismarckia nobilis (Hildebr. & Wendl.) in diarrhea, hypertension and asthma by ex-vivo and in-vivo method

To explore the mechanistic basis behind smooth muscle relaxant prospective of Bismarckia nobilis in gastrointestinal, respiratory and cardiovascular ailments. The methanolic extract of B. nobilis and sub-fractions have been evaluated in vitro rabbit isolated tissues, in vivo castor oil-induced diarrhea i...

Effects of Continuous and Accumulated Exercise on Endothelial Function in Rat Aorta

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. Objective: to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Metho...

The effect of chronic nitric oxide inhibition on vascular reactivity and blood pressure in pregnant rats

Säo Paulo med. j; 117 (5), 1999
CONTEXT: The exact mechanism involved in changes in blood pressure and peripheral vascular resistance during pregnancy is unknown. OBJECTIVE:To evaluate the importance of endothelium-derivated relaxing factor (EDRF) and its main component, nitric oxide, in blood pressure and vascular reactivity in pregna...

Efectos vasculares del tiopental
Vascular efects of thiopental

Rev. mex. anestesiol; 19 (4), 1996
Se evaluaron los efectos del tiopental en anillos de aorta de rata. El anestésico produjo contracción que aumentó al quitar el endotelio y no se inhibió con indometacina (10-5M). Prazosina (10-6M) o idazoxan (10-6M) o diltiazem (10-6M) pero disminuyó en un medio sin calcio. Por otra parte, el tiopen...
