Endothelial Dysfunction and Inflammation Precedes Elevations in Blood Pressure Induced by a High-Fat Diet

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Obesity leads to a chronic inflammatory state, endothelial dysfunction and hypertension. Objective: To establish the time-course of events regarding inflammatory markers, endothelial dysfunction, systolic blood pressure (SBP) in obesity in only one experimental model. Methods: We ...

Cardioprotective effect of lipstatin derivative orlistat on normotensive rats submitted to cardiac ischemia and reperfusion

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate in vivo animal model of cardiac ischemia/reperfusion the cardioprotective activity of pancreatic lipase inhibitor of the orlistat. Methods: Adult male Wistar rats were anesthetized, placed on mechanical ventilation and underwent surgery to induce cardiac I/R by obstructin...

Effects of hypothermia on lung inflammation in a rat model of meconium aspiration syndrome

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the effects of hypothermia treatment on meconium-induced inflammation. Methods: Fifteen rats were instilled with human meconium (MEC, 1.5 mL/kg, 65 mg/mL) intratracheally and ventilated for 3 hours. Eight rats that were ventilated and not instilled with meconium served a...

Impact of 1 25(OH) 2 D 3 on TG content in liver of rats with type 2 diabetes

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the effects of 1,25 dihydroxy vitamin D3 (1,25(OH)2D3) on the content of triglyceride (TG), as well as on the gene and protein expressions of adiponectin receptor 2 (AdipoR2), p38 mitogen-activated protein kinase (P38MAPK), and lipoprotein lipase (LPL) in the liver of rats...

Antioxidant extract counteracts the effects of aging on cortical spreading depression and oxidative stress in the brain cortex

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the effects of Murici extract on the brain excitability-dependent phenomenon known as cortical spreading depression (CSD) and on brain oxidative stress. Methods: Adult and aged Wistar rats were supplemented with murici extract (150 mg/kg/day or 300 mg/kg/day) by gavage...

Synergistic effect of honey and Nigella sativa on wound healing in rats

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the therapeutic potential of honey, Nigella sativa (N. sativa) and their combination in rat model of excisional wound healing. Methods: A circular excision wound was established in the back region of 50 Wistar rats. Subsequently, they were divided into 5 groups and da...

The therapeutic effects of curcumin and capsaicin against cyclophosphamide side effects on the uterus in rats

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the impact of systemic cyclophosphamide treatment on the rat uterus and investigate the potential therapeutic effects of natural antioxidant preparations curcumin and capsaicin against cyclophosphamide side effects. Methods: A 40 healthy adult female Wistar albino rats w...

An experimental study on the preventive effects of N-acetyl cysteine and ozone treatment against contrast-induced nephropathy

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To compare the preventive effects of N-acetyl cysteine (NAC), ozone preconditioning and ozone treatment against contrast-induced nephropathy (CIN) in an experimental rat model. Methods: Thirty adult male Wistar rats were randomly distributed into five groups (n=6 for each group). Gro...

Neurotrophin expression and histomorphometric evaluation in Wistar rats subjected to neural mobilization after compression of the median nerve

ABSTRACT Objective: To evaluate the neurotrophin mRNA expression and axon count in the median nerve of Wistar rats submitted to neural mobilization (NM) after nerve compression. Methods: Eighteen animals were randomly divided into G1 (nerve compression only), G2 (NM for 1 min), and G3 (NM for 3 min). F...

Protein from Hevea brasiliensis "Hev b 13" latex attenuates systemic inflammatory response and lung lesions in rats with sepsis

Braz. j. biol; 78 (2), 2018
Abstract Sepsis induces a severe systemic inflammatory response that may result in multiple organ dysfunction and death. Studies using a protein derived from natural Hevea brasiliensis (rubber tree) latex, denominated Hev b 13, have demonstrated important anti-inflammatory effects, but no data have been ...
