Erdosteine ameliorates the harmful effects of ischemia-reperfusion injury on the liver of rats

Acta cir. bras; 32 (10), 2017
Abstract Purpose: To investigate the potential protective effects of erdosteine against the harmful effects of ischemia-reperfusion injury on the liver in an experimental rat model. Methods: Forty rats were divided into 4 groups. In the sham group, only the hepatic pedicle was mobilized. No other mani...

Effect of ovariectomy in bone structure of mandibular condyle

Acta cir. bras; 32 (10), 2017
Abstract Purpose: To evaluate the bone structure of the mandibular condyle through an animal model, after ovariectomy. Methods: Thirty-six female Wistar rats were divided into 2 groups. The OVX group was submitted to bilateral ovariectomy, the SHAM group underwent the same surgical treatment, but with...

Attenuation of partial unilateral ureteral obstruction - induced renal damage with hyperbaric oxygen therapy in a rat model

Int. braz. j. urol; 43 (5), 2017
ABSTRACT Objective: The objective of the present study was to evaluate the effectiveness of HBO therapy on biochemical parameters, renal morphology and renal scintigraphy in rats undergoing chronic unilateral partial ureteral obstruction (UPUO). Material and methods: Thirty-five rats were divided into ...

The effect of melatonin and vitamin C treatment on the experimentally induced tympanosclerosis: study in rats

Abstract Introduction: The ethiopathogenesis of tympanosclerosis has not been completely under- stood yet. Recent studies have shown that free oxygen radicals are important in the formation of tympanosclerosis. Melatonin and Vitamin C are known to be a powerful antioxidant, interacts directly with React...

Agreement, correlation, and kinetics of the alveolar bone-loss measurement methodologies in a ligature-induced periodontitis animal model

J. appl. oral sci; 25 (5), 2017
Abstract Periodontal research involves the use of animal models to better understand the biological processes of periodontal diseases and the potential of new or existing therapies. Currently, ligature-induced periodontitis in rats is the main model used in periodontal research, in this model, alveolar b...

Effects of dimethylsulfoxide and pentoxifylline in the vitality of cutaneous flaps in rats

Rev. Col. Bras. Cir; 44 (5), 2017
ABSTRACT Objectives: to verify the influence of dimethylsulfoxide and pentoxifylline on the vitality of cutaneous flaps in rats and the tissue repair process. Methods: were studied 30 Wistar rats, submitting them to a 2cm wide by 8cm long dorsal cutaneous flap, of caudal base. We distributed the anim...

Influence of the colon in liver regeneration of rats submitted to hepatectomy and colectomy

Rev. Col. Bras. Cir; 44 (5), 2017
ABSTRACT Objective: to evaluate whether colectomy, associated with 70% hepatectomy, influences liver regeneration in rats. Methods: we distributed 18 Wistar rats in three groups of six animals each. In group I (sham), we performed laparotomy; In group II, colectomy + 70% hepatectomy; In group III, on...

Chronic dosing with mirtazapine does not produce sedation in rats

Objective: Sedation/somnolence are major side effects of pharmacotherapies for depression, and negatively affect long-term treatment compliance in depressed patients. Use of mirtazapine (MIR), an atypical antidepressant approved for the treatment of moderate to severe depression with comorbid anxiety dis...

Potential radioprotective effect of AT1 receptor antagonists against morphological and ultrastructural changes in the testes induced by ionizing radiation

Int. j. morphol; 35 (3), 2017
Radiotherapy is a source of human exposure to ionizing radiation. This pure energy causes deleterious effects on tissues, which result from oxidative stress, a phenomenon in which there is the participation of the Renin-Angiotensin System (RAS). The male genital organs are extremely radiosensitive and th...

Protective effect of Momordica cochinchinensis (L. ) spreng aril extract on essential testicular markers in rats induced with valproic acid

Int. j. morphol; 35 (3), 2017
Valproic acid (VPA), an anti-epileptic drug, has been reported to cause male sub/infertility. Together with searching for alternative treatments, the degrees to which testosterone levels and sperm quality are decreased under VPA treatment also need to be clarified. This study aimed to investigate the pro...
