This investigation assessed a biodegradable collagen membrane which can be sutured around the ureter to prevent urine leakage, thus permitting healing to proceed more rapidly while the membrane itself is resorbed. Following an early in vitro investigation in which collagen was assessed, a more comprehensive survey has now been carried out. Tissue compatibility and biodegradation were assessed b...

This study aimed to measure the TNF-α level in rat blood serum during wound healing process using collagen membrane. Methods: 24 male Wistar rats were divided into two groups: treatment and control. A bone defect was created on the rat’s jaw using a 2 mm diamond bur. The defect was then covered with collagen membrane in the treatment group and without collagen membrane cover in control group. R...

The purpose of this study was to evaluate a thin gelatin hydrogel membrane containing β-tricalcium phosphate (G-TCP) for use in guided bone regeneration, a technique that we developed. G-TCP membranes were fabricated from gelatin and β-TCP powder, freezedried, and cross-linked by heating. The resulting G-TCP membranes were as thin as collagen membranes, with high mechanical integrity. Prolifera...

Resolvin E1 is a metabolite of eicosapentaenoic acid (EPA) which one the omega-3 polyunsaturated fatty acids (omega-3 PUFAs). The antiplatelet properties PUFAs are well known, but effect resolvin on platelets via collagen receptors extremely poorly reported. We investigated collagen-induced platelet aggregation, activation, and reactivity, also membrane fluidity. ultimate statistically signific...

Introduction: During nephrogenesis, transition of mesenchyme to the epithelium of tubules and glomeruli occurs via the interaction of ureteral bud and metanephric mesenchyme. The distribution pattern of collagen type IV suggests that a regulated balance of activities is required to facilitate migration of the ureteral bud branches into the mesenchyme and to control early extracellular matrix ch...

Collagen based dressings for acute burn wound management have been extensively used in India, particularly in the city of Chennai. Due to the high levels of humidity in our city, closed dressings become infected and treatment with topical antimicrobials, like Silver Sulfadiazine cream, quickly become desiccated. Collagen membrane dressings were manufactured by the biomaterial laboratory of the ...

PURPOSE Silk fibroin (SF) is a new degradable barrier membrane for guided bone regeneration (GBR) that can reduce the risk of pathogen transmission and the high costs associated with the use of collagen membranes. This study compared the efficacy of SF membranes on GBR with collagen membranes (Bio-Gide®) using a rat calvarial defect model. MATERIALS AND METHODS Thirty-six male Sprague Dawley ...
