Action of a deproteinized xenogenic biomaterial in the process of bone repair in rats submitted to inhalation of cigarette smoke

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate if the inorganic bovine bone matrix changes the bone formation in rats submitted to inhalation of cigarette smoke. Methods: Twenty Wistar rats were divided into two groups: Cigarette Clot Group (CCG), which in the inhalation chamber received the smoke of 10 cigarettes...

Effects of Copaiba oil in the healing process of urinary bladder in rats

Int. braz. j. urol; 44 (2), 2018
ABSTRACT Introduction The appropriate closure of the urinary bladder is important to many urologic procedures to avoid the formation of fistulas and strictures by excessive fibrosis. This paper presents the alterations in the bladder healing process of rats after the topical use of Copaiba oil (Copaifer...

Effect of ischemic postconditioning and atorvastatin in the prevention of remote lung reperfusion injury

Abstract Objective: The aim of the present study was to evaluate the ability of ischemic postconditioning, atorvastatin and both associated to prevent or minimize reperfusion injury in the lung of rats subjected to ischemia and reperfusion by abdominal aortic clamping. Methods: We used 41 Wistar norveg...

Impact of a High-Intensity Training on Ventricular Function in Rats After Acute Myocardial Infarction

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Physical exercise should be part of the treatment of post-acute myocardial infarction (AMI) patients. Objective: To evaluate the effects of two training prescription models (continuous x interval) and its impact on ventricular function in rats after AMI with normal ventricular func...

Propentofylline decreases hypothalamic astrogliosis induced by hypercaloric diet in the rat

Arq. neuropsiquiatr; 76 (4), 2018
ABSTRACT Obesity is associated with a chronic and low-grade inflammatory response in the hypothalamus, where astrogliosis occurs with the upregulation of the astrocyte structural protein GFAP. As propentofylline (PPF) has inhibitory effects on astrocyte and microglial activation during inflammation, this...

Using the Reduced Uterine Perfusion Pressure model of preeclampsia to study the blood brain barrier permeability

AIMS: To use the Reduced Uterine Perfusion Pressure (RUPP) model for preeclampsia to describe and evaluate the blood brain barrier permeability in pregnant rats. METHODS: Forty-one pregnant Wistar rats were divided into different intervention groups between 13 to 15 days of gestation: PregnantControl (PC...

Preoperative subcutaneous sildenafil injection increases random flap survival in rats

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To investigate the effect of subcutaneous sildenafil on random flap survival. Methods: Fourteen Wistar rats, which were divided in to two groups, were used for this experimental study. Rats in the sildenafil group received subcutaneous sildenafil injections daily for seven days befo...

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...

The effect of metyrosine on oxidative gastric damage induced by ischemia/reperfusion in rats. Biochemical and histopathological evaluation

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To investigate the effect of metyrosine against I/R induced gastric damage in rats. Methods: Eighteen albino Wistar male rats were divided into groups; gastric I/R (GIR), 50 mg/kg metyrosine+gastric I/R (MGIR), and sham (SG) groups. 50 mg/kg metyrosine was given to the MGIR group, a...
