Acompanhamento eletrocardiográfico no desenvolvimento de ratos Wistar

A atividade elétrica cardíaca pode ser registrada por meio do eletrocardiograma (ECG), registro capaz de captar as alterações do percurso elétrico. Na literatura científica, não existe descrição de padrões eletrocardiográficos de ratos Wistar desde a fase de recém-nascidos até serem consider...

Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals

J. appl. oral sci; 25 (1), 2017
Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of mi...

Liver metabolic changes induced by conjugated linoleic acid in calorie-restricted rats

ABSTRACT Objective Complexes like conjugated linoleic acid (CLA) reduce the percentage of body fat by increasing energy expenditure, fat oxidation, or both. The aim of this study was to verify if CLA is able to mimic caloric restriction (CR), and determine the effects of CLA on liver metabolic profile ...

Influence of the use of testosterone associated with physical training on some hematologic and physical parameters in older rats with alloxan-induced diabetes

ABSTRACT Objective This study investigated the possible blood changes in wistar rats elderly with and without treatment with anabolic steroids submitted physical training. Materials and methods Elderly rats (32) were divided into four groups: normal (N), treated normal (NT), diabetic (D) and treated ...

Vitamin C decreases the obesogenic and hyperglycemic effect of invert sugar in prediabetic rats

Rev. Nutr. (Online); 30 (1), 2017
ABSTRACT Objective: To evaluate whether vitamin C can help to prevent obesity and hyperglycemia in Wistar rats treated with excess invert sugar to induce prediabetes. Methods: One hundred-day-old Male Wistar rats with a mean weight of 336.58±23.43g were randomly assigned to the following groups: (1) ...

Serotoninergic Modulation of Basal Cardiovascular Responses and Responses Induced by Isotonic Extracellular Volume Expansion in Rats

Arq. bras. cardiol; 108 (2), 2017
Abstract Background: Isotonic blood volume expansion (BVE) induced alterations of sympathetic and parasympathetic activity in the heart and blood vessels, which can be modulated by serotonergic pathways. Objective: To evaluate the effect of saline or serotonergic agonist (DOI) administration in the hyp...

Resveratrol Treatment Normalizes the Endothelial Function and Blood Pressure in Ovariectomized Rats

Arq. bras. cardiol; 108 (2), 2017
Abstract Background: Despite knowing that resveratrol has effects on blood vessels, blood pressure and that phytostrogens can also improve the endothelium-dependent relaxation/vasodilation, there are no reports of reveratrol's direct effect on the endothelial function and blood pressure of animals with ...

Cystometric analysis of the transplanted bladder

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Objective Cystometric evaluation of the bladder after autotransplant and isogeneic transplant in female rats. Material and Methods Two groups were constituted: (A) bladder autotransplant with two subgroups: R1 – (control) and R2 – (bladder transplant); (B) isogeneic bladder trans...

The effects of intra-cerebroventricular administered rocuronium on the central nervous system of rats and determination of its epileptic seizure-inducing dose

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background: The aim of this study was to investigate the effects of intracerebroventricularly administered rocuronium bromide on the central nervous system, determine the seizure threshold dose of rocuronium bromide in rats, and investigate the effects of rocuronium on the central nervous syste...

Effects of diazoxide in experimental acute necrotizing pancreatitis

Clinics; 72 (2), 2017
OBJECTIVE: We aimed to assess the effects of diazoxide on the mortality, pancreatic injury, and inflammatory response in an experimental model of acute pancreatitis. METHODS: Male Wistar rats (200-400 g) were divided randomly into two groups. Fifteen minutes before surgery, animals received physiologica...
