Proteomic Analysis of Lipopolysaccharide-treated Submandibular Gland in Rat
Proteome Submandibular gland Lipopolysaccharide Inflamation Ubiquitin
2011/6/10
We investigated changes in the protein profile of submandibular gland (SMG) with inflammation induced by exposure to lipopolysaccharide (LPS) with the aim of identifying potential molecular markers of...
Effect of Stretching Stress on Gene Transcription Related to Early-phase Differentiation in Rat Periodontal Ligament Cells
Periodontal ligament Mechanical stress Homeostasis
2010/12/1
Mechanical stress such as occlusal and orthodontic loading has been suggested to induce a homeostatic and regenerative response in periodontal ligament (PDL), but the underlying mechanism remains to b...
Effect of Celecoxib on Emotional Stress and Pain-Related Behaviors Evoked by Experimental Tooth Movement in the Rat
Pain Celecoxib Tooth movement Behavior
2010/3/9
Objective: To test the efficacy of an animal model of pain and stress and evaluate the effects of celecoxib administered when orthodontic force is applied.

Morphometric characterization of sexual differences in the rat sublingual gland
Sublingual gland Rats Sex characteristics
2009/10/20
The presence of morphological differences in the sublingual gland of male and female adult rats was determined by morphometry. Absolute and relative glandular mass was 21% lower and 31% higher, respec...
Assessment of methyl methacrylate vapor toxicity on the rat tracheal epithelium
Methylmethacrylate Trachea Toxicity
2009/10/20
Methyl methacrylate (MMA) is a monomer that is polymerized into resin by light and heat, producing a clear, resistant, durable and relatively inert plastic material. Because of these characteristics, ...
Study of the inflammatory process induced by injection of carrageenan or formalin in the rat temporomandibular joint
Temporomandibular joint Inflammation Carrageenan adverse effects Formalin
2009/10/19
The aim of this study was to evaluate the effects of the injection of two phlogistic agents, carrageenan and formalin, in the rat TMJ, and the inflammatory process induced by these substances. In this...
Effects of fibrin sealer and resorbable gelatin on the repair of osseous defects in rat tibia
Fibrin foam Fibrin tissue adhesive Osteogenesis Rats Tibia
2009/10/19
Gelfoam® - a biologically resorbable gelatin sponge - has the function of restricting hemorrhage, providing platelet rupture, and supporting fibrin threads. Beriplast® - a fibrinogen-thrombin ...
Microscopic qualitative evaluation of fixation time and decalcification media in rat maxillary periodontium
Histology Periodontium Dental research
2009/10/19
The rat model is widely used in periodontal research and the quality of histological sections is essential. The purpose of this study was to evaluate the histological characteristics of periodontal ti...
The bone-healing effect of a xenograft in a rat calvarial defect model
Xenograft Bone regeneration Rat
2009/9/11
Bone grafts have been widely used to fill osseous defects in medicine, dentistry, and periodontology. The purpose of this study was to investigate the effects of a xenograft (Unilab Surgibone®) on...
Surface analysis of commercially pure titanium implant retrieved from rat bone.part 1:Initial biological response of sandblasted surface
Dental implant Protein adsorption X-ray photoelectron spectroscopy
2009/9/11
To gain insight on the early biological response to commercial pure titanium (cpTi), the surface properties of cpTi implants retrieved from rat bone were examined by X-ray photoelectron spectroscopy (...
Combination with allogenic bone reduces early absorption of β-tricalcium phosphate (β-TCP) and enhances the role as a bone regeneration scaffold. Experimental animal study in rat mandibular bone defects
β-TCP Scaffold Bone regeneration
2009/9/11
β-tricalcium phosphate (β-TCP) was grafted into rat mandibular bone defects to assess its potential as a scaffold material for bone regeneration. For this purpose, β-TCP (TCP), allogenic bone (Allogra...
