Effects of crocin on brain oxidative damage and aversive memory in a 6-OHDA model of Parkinson's disease

Arq. neuropsiquiatr; 74 (9), 2016
ABSTRACT The purpose of the present study was to investigate the effect of crocin on brain oxidative damage and memory deficits in a 6-hydroxydopamine (6-OHDA) model of Parkinson’s disease. Male Wistar rats were subjected to unilateral injection of 6-OHDA (16 µg) into the medial forebrain bundle a...

Enduring amnesia induced by ICV scopolamine is reversed by sesame oil in male rats

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To evaluated the long-term effect of scopolamine and sesame oil on spatial memory. METHODS: Memory impairment induced by Intracerebroventricular (ICV) injection of scopolamine hydrochloride (10 μg/ rat). Animals were gavaged for 4 weeks with saline, sesame oil (0.5, 1, or 2 mL/k...

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...

Antioxidant effect of Legalon(r) SIL in ischemia-reperfusion injury of rat skeletal muscle

Acta cir. bras; 31 (4), 2016
PURPOSE: To evaluated the potential antioxidant agent Legalon (r) SIL (silibinin-C-2',3-bis(hydrogensuccinat)) in the skeletal muscle of rats. METHODS: IRI was achieved via tourniquet application in Wistar-albino rats. Experimental groups were chosen as (i) sham control, (ii) IRI (3+2 h), (iii) IRI a...

MnSOD and GPx1 polymorphism relationship with coronary heart disease risk and severity

Biol. Res; 49 (), 2016
BACKGROUND: Disturbance of the equilibrium between reactive oxygen species (ROS) and anti-oxidants (AOX) has been implicated in various diseases, including atherosclerosis, the most common pathologic process underlying coronary heart disease (CHD). Thus, the defense systems against ROS are critical prote...

Influência dos polimorfismos Pro198Leu, -602A/G e Arg5Pro na atividade da enzima glutationa peroxidase e no estado nutricional de indivíduos adultos com relação ao selênio

O objetivo deste estudo foi avaliar o estado nutricional relativo ao selênio em indivíduos adultos relacionando-o com polimorfismos no gene da enzima GPx e sua influência sobre a enzima e o balanço redox. Foram selecionados 343 estudantes da Universidade Federal do Piauí entre 20 e 50 anos, de ambos...

Mechanisms involved in reproductive damage caused by gossypol in rats and protective effects of vitamin E

Biol. Res; 48 (), 2015
BACKGROUND: Gossypol is a chemical present in the seeds of cotton plants (Gossypium sp.) that reduces fertility in farm animals. Vitamin E is an antioxidant and may help to protect cells and tissues against the deleterious effects of free radicals. The aim of this study was to evaluate the mechanisms of ...

Efeito da suplementação com castanha-do-brasil (Bertholletia excelsa H. B. K) como fonte de selênio sobre os marcadores de estresse oxidativo, citocinas inflamatórias e sua relação com o polimorfismo Pro198Leu no gene da glutationa peroxidase 1 em pacientes com artrite reumatoide

A artrite reumatoide (AR) é uma doença inflamatória crônica, caracterizada por inflamação das articulações e se manifesta por inchaço e incapacidade funcional das mesmas. A patologia da doença envolve a produção excessiva de radicais livres pelos neutrófilos ativados, podendo induzir à pero...
