Pterostilbeno Reduz o Estresse Oxidativo no Pulmão e no Ventrículo Direito Induzido por Infarto do Miocárdio Experimental

Arq. bras. cardiol; 118 (2), 2022
Resumo Fundamento O pterostilbeno (PS), um composto polifenólico natural e antioxidante, surge como uma intervenção promissora para minimizar danos do infarto agudo do miocárdio (IAM). Objetivo Este estudo teve como objetivo avaliar o desempenho do PS na promoção da homeostase redox nos pulmõe...

Alprostadil attenuates myocardial ischemia/reperfusion injury by promoting antioxidant activity and eNOS activation in rats

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To investigate the effect of alprostadil on myocardial ischemia/reperfusion (I/R) in rats. Methods: Rats were subjected to myocardial ischemia for 30 min followed by 24h reperfusion. Alprostadil (4 or 8 μg/kg) was intravenously administered at the time of reperfusion and myocar...

Impact of dexmedetomidine on hemodynamics in rabbits

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To evaluate the effects of single intravenous administration of Dexmedetomidine (DEX) on hemodynamics in rabbits. Methods: A total of 32 New Zealand white rabbits were randomly divided into the control group (Group C), Group D1 (2.75 μg/kg), Group D2 (5.5 μg/kg), and Group ...

Mesenchymal stem cells reduce left ventricular mass in rats with doxorubicin-induced cardiomyopathy

Int. j. morphol; 36 (1), 2018
SUMMARY: Doxorubicin is a drug that used by a majority in the treatment of carcinomas. The most obvious known side effect is cardiomyopathy. Many studies have been carried out to eliminate side effects of the doxorubicin, and stem cell studies have been added in recent years. In this study, it was aimed ...

Lactate-upregulation of lactate oxidation complex-related genes is blunted in left ventricle of myocardial infarcted rats

Braz. j. med. biol. res; 51 (11), 2018
Lactate modulates the expression of lactate oxidation complex (LOC)-related genes and cardiac blood flow under physiological conditions, but its modulatory role remains to be elucidated regarding pathological cardiac stress. The present study evaluated the effect of lactate on LOC-related genes expressio...

Pentoxifylline Attenuates Cardiac Remodeling Induced by Tobacco Smoke Exposure

Arq. bras. cardiol; 106 (5), 2016
Abstract Background: Tobacco smoke exposure is an important risk factor for cardiac remodeling. Under this condition, inflammation, oxidative stress, energy metabolism abnormalities, apoptosis, and hypertrophy are present. Pentoxifylline has anti‑inflammatory, anti-apoptotic, anti-thrombotic and a...

A normalizaçäo da complacência e da hipertrofia ventricular na hipertensäo arterial: estudo duplo-cego com duas associaçöes de betabloqueador e diurético
The standardization of compliance and ventricular hypertrophy in arterial hypertension: double-blind study with 2 combinations of beta blockers and diuretics

Arq. bras. cardiol; 48 (6), 1987
Foi avaliada a complacência e a hipertrofia ventricular em 24 pacientes com hipertensäo arterial (HA) leve ou moderada (pressäo sistólica entre 160 a 180 e diastólica entre 90 e 120 Hg). Doze pacientes tomaram diariamente 100 mg de atenolol e 25 mg de clortalidona (grupo A) e 12 tomaram 100 mg de me...
