The positive effect of Botulinum toxin type A on the viability of random flap in tobacco exposed in rats

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To evaluate the effect of Botulinum Toxin A in different time of tobacco exposure. METHODS: 60 male, Wistar rats were divided into two tobacco exposure groups: a 2- month or a 4-month regimen. After this period, these two groups were subdivided as two: saline solution(SS) or botulin...

Characterization of an experimental model of progressive renal disease in rats

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To characterize an experimental model of progressive renal disease induced by different degrees of nephrectomy in rats. METHODS: Eighty male Wistar rats were divided into four experimental groups (n=20/group): sham surgery (control group), progressive degrees of nephrectomy leading to...

Osteoarthritis model induced by intra-articular monosodium iodoacetate in rats knee

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To evaluate the usefulness of a knee osteoarthritis model through functional, radiological and microscopic changes of the synovial membrane. METHODS: Forty eight rats were divided randomly into two groups. The first received 0.9% saline in the joint and corresponded to the control gro...

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To analysis the effects of passive smoking on the microstructure of tissues of the abdominal wall regarding microcirculation, using histopathological study of the tobacco exposed rats. METHODS: Twenty four male Wistar rats were divided in Control Group (CG = 8 animals) and Exposition...

The effects of enoxaparin on the liver in experimental pneumoperitoneum model

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To investigate the potential protective effects of enoxaparin against the adverse events of carbon dioxide (CO2) pneumoperitoneum. METHODS: Thirty four rats were divided into three groups: Group 1 (sham) underwent insertion of Veress needle into the abdomen and 90 min of anesthesia wi...

Influence of chlorpromazine on renal histology of rats submitted to ischemia and reperfusion injury

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To analyze the influence of chlorpromazine on renal histology of rats submitted to ischemia and reperfusion injury. METHODS: Sixteen Wistar rats - split in two groups - have been used: control group, receiving 3 mg/kg isotonic saline solution through caudal vein, and, the chlorpromazi...

Acute Ethanol Intake Induces NAD(P)H Oxidase Activation and Rhoa Translocation in Resistance Arteries

Arq. bras. cardiol; 107 (5), 2016
Abstract Background: The mechanism underlying the vascular dysfunction induced by ethanol is not totally understood. Identification of biochemical/molecular mechanisms that could explain such effects is warranted. Objective: To investigate whether acute ethanol intake activates the vascular RhoA/Rho ki...

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objective: To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. Materials and Methods: A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneo...

Vertical gastrectomy in overweight and non-overweight rats

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To compare the two lines suture (total and seromuscular) after partial gastrectomy in normal and overweight rats. METHODS: Forty Wistar rats were distributed in two groups. Group A received normal diet; group B, normal diet and supplementation with saccharose in the water. When group ...
