Preconditioning with mono and polyunsaturated fatty acids and low-intensity ele...

PURPOSE: To evaluate the effects of preconditioning with oils mixes containing ω3/ω6/ω9 associated with micro-currents on skin repair in rats. METHODS: One-hundred and eight Wistar rats randomized into G-1, G-2 and G-3 groups were treated with saline (0.9%), mix 1 (corn+soybean oils) and mix 2 (olive+canola+flaxseed oils), respectively, in a single dose (0.01ml/g) by gavage. Next, each group was subdivided into...

Fructo-oligosaccharide effects on serum cholesterol levels. An overview

PURPOSE:To address the effects of fructooligosaccharides (FOS) intake on serum cholesterol levels.METHODS: We performed a search for scientific articles in MEDLINE database from 1987 to 2014, using the following English keywords: fructooligosaccharides; fructooligosaccharides and cholesterol. A total of 493 articles were found. After careful selection and exclusion of duplicate articles 34 references were selec...

Glutamine and ornithine alpha-ketoglutarate supplementation on malate dehydroge...

PURPOSE: To evaluate the relative gene expression (RGE) of cytosolic (MDH1) and mitochondrial (MDH2) malate dehydrogenases enzymes in partially hepatectomized rats after glutamine (GLN) or ornithine alpha-ketoglutarate (OKG) suplementation. METHODS: One-hundred and eight male Wistar rats were randomly distributed into six groups (n=18): CCaL, GLNL and OKGL and fed calcium caseinate (CCa), GLN and OKG, 0.5g/Kg b...

Effects of acupuncture and electroacupuncture on estradiol-induced inflammation...

PURPOSE:To investigate the effects of classical acupuncture (Ac) and electroacupuncture (EAc) on estradiol-induced inflammation and oxidative stress in health rodents. METHODS: Twenty-four eight-week old female rats were treated with estradiol valerate (EV) 4.0 mg i.m. single dose and randomly assigned to four groups (n=6): G1(control), G2 (Ac), G3 (EAc 2 Hz) and G4 (EAc 100 Hz). After 60 days all rats were ane...

Fructo-oligosaccharide effects on blood glucose: an overview

PURPOSE: To identify the current status of scientific knowledge in fructo-oligosaccharides (FOS), non-conventional sugars that play an important role in glycemia control. METHODS: We performed a search for scientific articles in MEDLINE and LILACS databases, from January 1962 to December 2011, using English/Portuguese key words: "blood glucose/glicemia", "prebiotics/prebióticos" and "dietary fiber/fibras na die...

Ternatin pretreatment attenuates testicular injury induced by torsion/detorsion...

PURPOSE: To investigate the possible protective role of the bioflavonoid ternatin (TTN) when administered before induction of ischemia/reperfusion injury in rat testis. METHODS: Thirty-six Wistar rats were randomly assigned to 3 groups (n=12), divided in 2 subgroups (n=6). Saline 2.0ml (G-1), dimethylsulfoxide (DMSO) 3% solution (G-2) or TTN 12 mg/kg/dose (G-3) was administered ip. to all rats, respectively, 21...

Preconditioning with L-alanyl-L-glutamine in a Mongolian Gerbil model of acute ...

PURPOSE: To investigate the effect of L-alanyl-L-glutamine (L-Ala-Gln) preconditioning in an acute cerebral ischemia/reperfusion (I/R) model in gerbils. METHODS: Thirty-six Mongolian gerbils (Meriones unguiculatus), (60-100g), were randomized in 2 groups (n=18) and preconditioned with saline 2.0 ml (Group-S) or 0.75g/Kg of L-Ala-Gln, (Group-G) administered into the femoral vein 30 minutes prior to I/R. Each gro...

L-Alanyl-Glutamine dipeptide pretreatment attenuates ischemia-reperfusion injur...

PURPOSE: To investigate the effect of alanyl-glutamine dipeptide (L-Ala-Gln) pre-treatment on ischemia-reperfusion (I/R) injury after unilateral testicular torsion-detorsion in a comparative controlled experiment. METHODS: Forty-eight rats (150-200 g) randomly distributed into 4 groups (n=12), and distributed in 2 subgroups (n=6) each, were treated with saline 2.0 ml (G-1, G-3) or L-Ala-Gln 20%, 0.75g/kg dissol...

An optimized animal model for partial and total skin thickness burns studies

PURPOSE: Development of an improved animal model for studying skin burns in rats. METHODS: Twenty-four male Wistar rats were randomly assigned to four groups (n=6): G1-Control, G2- T100°C, G3-T150°C and G4-T200°C. Two 10 x 10 mm squares were outlined with a sterile surgical marker on each side and along the vertebral column using a prepared template positioned between the anterior and posterior limbs. G2-G4 rat...
