Comparison of different quantification methods for 18F-fluorodeoxyglucose-positron emission tomography studies in rat brains

Clinics; 74 (), 2019
OBJECTIVES: This study aimed to evaluate several methods to estimate glucose consumption in the male Wister rat brain as measured by PET. METHODS: Fourteen male Wistar normoglycemic rats were studied. The input function consisted of seventeen blood samples drawn manually from the femoral artery. Glucose...

The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway

Braz. j. med. biol. res; 52 (10), 2019
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium veri...

Phenotypic changes of interstitial cells of Cajal after intestinal obstruction in rat model

Braz. j. med. biol. res; 52 (10), 2019
The objective was to study the effect of mechanical intestinal obstruction in rats on the phenotype of interstitial cells of Cajal (ICC). Healthy Wistar rats were randomly divided into sham-operation group (C), one day obstruction group (M1), two days obstruction group (M2), and three days obstruction gr...

Short-term creatine supplementation changes protein metabolism signaling in hindlimb suspension

Braz. j. med. biol. res; 52 (10), 2019
The effect of a short-term creatine supplementation on hindlimb suspension (HS)-induced muscle atrophy was investigated. Creatine monohydrate (5 g/kg b.w. per day) or placebo, divided in 2 daily doses, was given by oral gavage for 5 days. Rats were maintained in HS with dietary supplementation concomitan...

Regeneration of Salivary Gland Defects of Diabetic Wistar Rats Post Human Dental Pulp Stem Cells Intraglandular Transplantation on Acinar Cell Vacuolization and Interleukin-10 Serum Level

Abstract Objective: To investigate the regeneration of rat's salivary gland diabetic defect after intraglandular transplantation of Human Dental Pulp Stem Cells (HDPSCs) on acinar cell vacuolization and Interleukin-10 (IL-10). Material and Methods: HDPSCs isolated from the dental pulp of first premolar...

The effect of colchicine on alveolar bone loss in ligature-induced periodontitis

Abstract Colchicine is widely used in the treatment of several inflammatory diseases due to its anti-inflammatory effect, but effects on bone metabolism are unclear. The aim of this study was to evaluate the effects of systemically-administered colchicine on healthy periodontium and experimentally-induce...

Metronidazole concentration in the bloodstream following its topical application, at different concentration levels, on experimental skin wounds during healing by secondary intention

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To characterize qualitatively and quantitatively the absorption of metronidazole solution, in greater concentrations and for longer periods, when applied topically to an experimental open skin wound model. Methods: An open skin wound, 2 cm in diameter and total skin thickness was prep...

Bone callus formation is highly disrupted by dietary restriction in growing rats sustaining a femoral fracture

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To evaluate the effects of food restriction on fracture healing in growing rats. Methods: Sixty-eight male Wistar rats were assigned to two groups: (1) Control and (2) Dietary restriction. After weaning the dietary restricted animals were fed ad libitum for 42 days with 50% of the s...

Comparative study of four different types of intraperitoneal mesh prostheses in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: To compare four types of mesh regarding visceral adhesions, inflammatory response and incorporation. Methods: Sixty Wistar rats were divided into four groups, with different meshes implanted intraperitoneally: polytetrafluoroethylene (ePTFE group); polypropylene with polydioxanone and...

Botulinum toxin as a treatment for short bowel syndrome in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: The denervation of the intestine with benzalkonium chloride (BAC) reduces mortality and improves weight gain in rats with short bowel syndrome (SBS). Nevertheless, translating these promising findings from bench to bedside is not feasible because BAC promotes peritonitis and irreversib...
