Interleukin-6 contributes to myocardial damage in pregnant rats with reduced uterine perfusion pressure

Braz. j. med. biol. res; 51 (8), 2018
Preeclampsia is one of the most frequent and difficult illnesses in pregnancy, which jeopardizes both mother and fetus. There are several diagnostic criteria for preeclampsia. However, the preeclampsia-associated myocardial damage has not been described. In this study, we employed reduced uterine perfusi...

Effect of atenolol pre-treatment in heart damage in a model of intestinal ischemia-reperfusion

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To investigate the effects of atenolol in inflammatory mediator and oxidative stress in a myocardial injury by intestinal ischemia/reperfusion in rat model. Methods: Adult Wistar male rats were randomly (n=8), anesthetized and divided in: Sham: submitted to operation only; group SS+...

Testosterone and Voluntary Exercise, Alone or Together Increase Cardiac Activation of AKT and ERK1/2 in Diabetic Rats

Arq. bras. cardiol; 107 (6), 2016
Abstract Background: Impaired angiogenesis in cardiac tissue is a major complication of diabetes. Protein kinase B (AKT) and extracellular signal regulated kinase (ERK) signaling pathways play important role during capillary-like network formation in angiogenesis process. Objectives: To determine the e...

The protective cardiac effects of Β-myrcene after global cerebral ischemia/reperfusion in C57BL/J6 mouse

Acta cir. bras; 31 (7), 2016
ABSTRACT PURPOSE: To investigate the protective effect of β-myrcene (MYR) on oxidative and histological damage in mice heart tissue caused global cerebral ischemia/reperfusion (IR) in C57BL/J6 mice. METHODS: Animals(n=40) were randomly divided into four groups: (1)control, (2)IR, (3)MYR and (4)MYR...

Effects of thymoquinone against cisplatin-induced cardiac injury in rats

Acta cir. bras; 31 (4), 2016
PURPOSE: T o investigate the possible protective effect of thymoquinone (TQ) in cisplatin (CP) induced myocardial injury. METHODS: A total of 28 adult male Wistar-Albino rats were randomly and equally divided into four groups as follows: Group 1 (control), Group 2 (CP at 15 mg/kg dose), Group 3 (TQ 40 ...

Deficiency of sex hormones does not affect 17-ß-estradiol-induced coronary vasodilation in the isolated rat heart

Braz. j. med. biol. res; 49 (5), 2016
The relaxation of coronary arteries by estrogens in the coronary vascular beds of naive and hypertensive rats has been well described. However, little is known about this action in gonadectomized rats. We investigated the effect of 17-ß-estradiol (E2) in coronary arteries from gonadectomized rats, as we...

El efecto anti-hipertensivo de angiotensina-(1-9) es mediado por aumento temprano de la diuresis y natriuresis

Rev. chil. cardiol; 34 (2), 2015
Introducción: Angiotensina (Ang)-(1-9) posee propiedades anti-hipertensivas y efecto protector a nivel cardiovascular en ratas hipertensas. Sin embargo, se desconoce si estos efectos están asociados a un mecanismo de desbalance de sodio a nivel renal. Objetivo: Determinar si el efecto anti-hipertensivo...

Influência da ingestäo aguda de bebidas alcoólicas sobre o aparelho cardiovascular: observaçäo clínica, eletrocardiográfica e laboratorial
Influence of acute intake of alcoholic beverages on the cardiovascular system: clinical, electrocardiographic and laboratory observation

Arq. bras. cardiol; 47 (1), 1986
Estudamos os efeitos da ingestäo aguda de bebidas alcoólicas sob o ponto de vista clínico, eletrocardiográfico e laboratorial, em 23 indivíduos, 16 sadios e 7 com antecedentes de cardiopatia, que näo faziam uso habitual de álcool. Todos apresentaram, após a ingestäo alcoólica, aumento significa...
