The role of oxidative stress in streptozotocin-induced diabetic nephropathy in rats

ABSTRACT Objective The objective of this study was to evaluate the role of oxidative stress in an experimental model of streptozotocin-induced diabetic nephropathy in rats. Materials and methods Wistar, adult, male rats were used in the study. Animals were divided in the following groups: Citrate (co...

The effects of photobiomodulation therapy on Staphylococcus aureus infected surgical wounds in diabetic rats. A microbiological, histopathological, and biomechanical study

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To evaluate the effects of photobiomodulation therapy (PBMT) at 685 nm on diabetic wound healing in rats suffering from bacterial infection induced by Staphylococcus aureus (S. aureus). METHODS: Thirty streptozotocin-induced diabetic rats were allocated into two groups: control and PB...

Improvement of erectile dysfunction by the active pepide from urechis unicinctus by high temperature/pressure and ultra - wave assisted lysis in streptozotocin induced diabetic rats

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Introduction: We investigate the effect of active peptide from Urechis unicinctus (UU) by high temperature/pressure and ultra-wave assisted lysis on erectile dysfunction in streptozotocin-induced diabetic rats. Materials and Methods: Forty 12-week-old Sprague-Dawley rats were used in this stud...

The effects of supplemental melatonin administration on the healing of bone defects in streptozotocin-induced diabetic rats

J. appl. oral sci; 24 (3), 2016
ABSTRACT Diabetes mellitus (DM) causes an increased production of free radicals that can impair bone healing. Melatonin is a hormone secreted mainly by the pineal gland, which participates in the neutralization process of free radicals. Objective The aim of this study was to investigate histologic and ...

Endoplasmic reticulum stress and renal lesion in mice with combination of high-fat diet and streptozotocin-induced diabetes

Acta cir. bras; 31 (3), 2016
ABSTRACT PURPOSE : To investigate in the kidney the pathologic changes and expression of GRP78 and CHOP in the Kunming (KM) mice with combination of high-fat diet and streptozotocin-induced diabetes. METHODS : Sixty two male KM mice were randomly divided into a normal control (NC) group (n=20) and a hi...

Caracterización de un modelo de diabetes tipo 2 en ratas y evaluación del papel de la angiotensina II y las especies reactivas de oxígeno en la resistencia neuronal a la insulina

La regulación ejercida por la insulina central en individuos diabéticos ha sido muy poco estudiada. La angiotensina II promueve el estrés oxidativo y la resistencia a la insulina. Dada la co-localización del receptor AT1 de la angiotensina II y el RI a nivel hipotalámico, en este trabajo, decidimos ...

Atualização em neuropatias periféricas relacionadas às alterações neurais e vasculares ocorrentes na diabetes mellitus em modelos animais

O trabalho de revisão sistemática aponta os principais aspectos patogênicos relacionados às lesões neurais e vasculares da neuropatia diabética, estudados em modelos animais. Tem como escopo comparar as diversas espécies animais utilizadas nos estudos, salientando os aspectos semelhantes encontrad...

Esquema de restriçäo alimentar altera a resposta celular à insulina em ratos diabéticos
Scheme of food restriction change the cellular response to insulin in rats

A resistência à insulina é um elemento chave na gênese de várias alterações fisiopatológicas. O esquema de restrição alimentar meal-feeding (MF) consiste na oferta de uma única refeição diária de 2h, sem, contudo, limitar a quantidade de alimento durante esse período. Este esquema determin...
