Protective effect of L-carnitine on myocardial injury in rats with heatstroke

Acta cir. bras; 35 (12), 2020
Abstract Purpose: To investigate the protective effect of L-carnitine on myocardial injury in rats with heatstroke. Methods: orty-eight rats were randomly divided into control, heatstroke and 25, 50 and 100 mg/kg L-carnitine groups. The last three groups were treated with 25, 50 and 100 mg/kg L-carniti...

The protective effect of Ganoderma lucidum on testicular torsion/detorsion-induced ischemia-reperfusion (I/R) injury

Acta cir. bras; 35 (1), 2020
Abstract Purpose To investigate the protective effect of Ganoderma lucidum on testicular torsion/detorsion (T/D)-induced ischemia-reperfusion (I/R) injury. Methods Thirty male Wistar albino rats were randomly categorized into 3 groups: Group 1: sham, Group 2 ( T/D): 2,5 hours of ischemia and 7 days of ...

Is the effect of melatonin on vascular endothelial growth factor receptor-2 associated with angiogenesis in the rat ovary?

Clinics; 74 (), 2019
OBJECTIVES Vascular endothelial growth factor (VEGF) and its receptors play important roles in angiogenesis. Melatonin plays an important role in gonadal development; thus, its effect on the reproductive system is evident. We investigated the influence of melatonin on the expression of VEGF, vascular en...

Entrenamiento físico de alta intensidad en maratonistas produce mayor remodelado cardíaco y reduce respuesta de estrés oxidativo

Rev. chil. cardiol; 37 (2), 2018
Resumen: Introducción: El ejercicio físico reduce la mortalidad cardiovascular y genera remodelado cardíaco. Altas cargas de entrenamiento pueden generar remodelado cardíaco adverso. Biomarcadores (BMC) de inflamación Interleukina 6 (IL-6) y de estrés oxidativo Malondialdehído (MDA), potencialmen...

Effects of baicalin on inflammatory reaction, oxidative stress and PKDl and NF-kB protein expressions in rats with severe acute pancreatitis

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To investigate the effects of baicalin on inflammatory reaction, oxidative stress and protein kinase D1 (PKD1) and nuclear factor-kappa B (NF-κB) protein expressions in severe acute pancreatitis (SAP) rats. Methods: Sixty rats were divided into sham operation, model, and low-, m...

Combined effects of melatonin and topical hypothermia on renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To evaluate whether their combination was more effective than either alone in decreasing renal damage due to ischemia/reperfusion (I/R) injury in rats. Methods: Thirty-two Wistar rats were assigned to four groups. Following right nephrectomy, their left kidneys were subjected to warm...

Gastrodin induced HO-1 and Nrf2 up-regulation to alleviate H2O2-induced oxidative stress in mouse liver sinusoidal endothelial cells through p38 MAPK phosphorylation

Braz. j. med. biol. res; 51 (10), 2018
Nuclear factor erythroid-related factor 2 (Nrf2) has been implicated in several detoxifying and antioxidant defense processes. Nrf2-mediated heme oxygenase-1 (HO-1) expression was demonstrated to play a key role against oxidative stress. Gastrodin (GSTD) is a well-known active compound isolated from the ...

Melatonin ameliorates H2O2-induced oxidative stress through modulation of Erk/Akt/NFkB pathway

Biol. Res; 51 (), 2018
BACKGROUND: Improper control on reactive oxygen species (ROS) elimination process and formation of free radicals causes tissue dysfunction. Pineal hormone melatonin is considered a potent regulator of such oxidative damage in different vertebrates. Aim of the current communication is to evaluate the leve...

Comparisons of the effects of the sevoflurane and propofol on acute ischemia reperfusion and DNA damages in rabbits

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background and objectives: The aim of this study was to compare the effects of sevoflurane and propofol anesthesia on oxidative DNA damage that occurs in low-extremity ischemia and is caused by tourniquet application. Methods: Fourteen New Zealand rabbits were randomly allocated into two equal...

Therapeutic effect of low molecular weight chitosan containing sepia ink on ethanol-induced gastric ulcer in rats

Acta cir. bras; 31 (12), 2016
ABSTRACT PURPOSE: To evaluate the role of low molecular chitosan containing sepia ink (LMCS) in ethanol-induced (5 ml/kg) gastric ulcer in rats. METHODS: Animals were divided into four groups (n = 12): normal group (Normal), negative control group (Con), experiment group (LMCS) and positive control Om...
