Development of a new model of actinic enteritis in rats using a cobalt-60 open source and a protection device as a collimator

Acta cir. bras; 32 (4), 2017
Abstract Purpose: To describe a new model of actinic enteritis that does not use radiotherapy machines. Methods: Sixteen Wistar rats were divided into four groups, consisting of four animals each: control (group A), two weeks after irradiation (group B), five weeks after irradiation (group C) and eigh...

Influence of β-tricalcium phosphate of different geometric shape on the morphology of regeneration of experimental defect of compact bone tissue

Actual. osteol; 13 (1), 2017
Purpose: to compare the healing process of a defect of compact bone tissue after the implantation of osteoplastic materials based on β-tricalcium phosphate (“ChronOS™” and “Calc-i-oss®”), which differ by manufacturer, geometrical shape and microscopic structure. Methods: the experiment was pe...

Different inoculum loads of Toxoplasma gondii induce reduction of myenteric neurons of the rat colon

Abstract Toxoplasmosis, a disease caused by Toxoplasma gondii, is an important health problem, especially in immunocompromised hosts. T. gondii uses the gut wall as an infection gateway, with tropism for muscular and nervous tissues causing intestinal alterations, including some in the enteric nervous sy...

The effects of individually ventilated cages on the respiratory systems of male and female Wistar rats from birth until adulthood

Clinics; 72 (3), 2017
OBJECTIVE: To evaluate the respiratory systems of male and female rats maintained in individually ventilated cages (IVCs) from birth until adulthood. METHODS: Female Wistar rats were housed in individually ventilated cages or conventional cages (CCs) and mated with male Wistar rats. After birth and wean...

Gestational diabetes induces pancreatic beta-bells apoptosis in adult rat offspring

Int. j. morphol; 35 (1), 2017
Several studies indicated that pancreatic ß-cell death occurs in both type 1 and type 2 diabetes. This experimental study was designed to determine the effect of gestational diabetes on the ß-cells in 16-week-old rat offspring. By this aim, adult Wistar rats aged 10-12 weeks were randomly allocated in ...

The effect of gestational diabetes mellitus on sciatic nerve in adult offspring rats

Int. j. morphol; 35 (1), 2017
Gestational diabetes mellitus (GDM) is one form of diabetes affect approximately 7 % of pregnancies. Diabetic peripheral neuropathy (DPN) is a common complication of diabetes that is associated with loss of nerve fibers, myelin abnormalities and significant decrease in the expression of myelin basic prot...

Apoptosis in bone defect of diabetic rats treated with low intensity laser: radiological and immunohistochemical approach

Int. j. morphol; 35 (1), 2017
The aim of this study is evaluate the efficacy of 904 nm laser diode in bone regeneration in the bone defect in diabetic rats. Six groups of 10 male Wistar rats and 2 mm bone defects drilled on the left and right tibia were used. The diabetic animals were treated with streptozotocin (40 mg/kg, i.v.). We ...

Effects of quercetin-supplementation in NADH-diaphorase positive neurons subpopulations in the ileum of rats with experimental diabetes mellitus

Int. j. morphol; 35 (1), 2017
The effects of quercetin supplementation in NADH-diaphorase positive (NADH-d) neurons of streptozotocin-induced diabetic rats was carried in this study. Fifteen male rats were divided into three groups: normoglycemic (N), diabetic (D) and diabetic supplemented with quercetin (DQ). Whole mount preparation...

Evaluation of the effect of platelet-rich plasma on alveolar wound healing in rats

Int. j. morphol; 35 (1), 2017
Opinions about the clinical utility of platelet-rich plasma (PRP) vary, as a large number of experimental studies have questioned its efficacy. The purpose of this study was to evaluate the effects of PRP on experimental alveolar wound healing in rats. Fifty young adult male Wistar rats were divided in c...

Hepatoprotective effects of Tibulus terrestris hydro-alcholic extract on non-alcoholic fatty liver- induced rats

Int. j. morphol; 35 (1), 2017
Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris (T. terrestris) extr...
