Acid-soluble collagen could be isolated from fish skin using acetic acid. In recent years, much attention has been paid to collagen from marine sources, mainly arising from the fact that there is no risk of contagious diseases. Moreover, by processing the fish, significant amounts of waste materials are produced which can be considered as a substitute for these collagen sources. Thunnus tonggol...

INTRODUCTION Hyperbaric oxygen and platelet-rich plasma are used in the treatment of diabetic wounds. The aim of this study is to evaluate the effects of hyperbaric oxygen therapy and autologous platelet concentrates in healing diabetic wounds. MATERIAL AND METHODS Thirty-six female Wistar albino rats were used in this study. Diabetes mellitus was induced chemically with an intraperitoneal in...

AIMS Stem cells are a new hope to ameliorate impaired diabetic wound healing. The purpose of this study was to evaluate the effect of adipose tissue derived mesenchymal stem cells (AD-MSCs) on wound healing in a diabetic rat model. METHODS Twenty-six rats became diabetic by a single intraperitoneal injection of streptozotocin. Six rats served as non-diabetic (non-DM). Diabetic rats were divid...

OBJECTIVE To understand the changes of femoral cartilage in response to treadmill running with different intensities in the hope of differentiating "moderate" and "strenuous" running in a rat model. METHOD A total of 24 male Wistar rats were randomly assigned into groups of sedentary (SED), low-intensity running (LIR), medium-intensity running (MIR), and high-intensity running (HIR). Rats in ...

Wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. Simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. In this study we aimed to determine the effect of simvastatin on wound healing process in...

Objective- To evaluate the effects of autologous platelet-rich plasma (PRP) on wound healing in dogs. Design- Experimental in-vivo study. Animals- 5 mix-breed male adult dogs. Procedures- Under general anesthesia, six 2 × 2-cm, full-thickness skin wounds were created on the back of dogs symmetrically. In each dog, three right side wounds were treated topically with 1.5 ml PRP jelly, whereas lef...

The present study was designed to fabricate a new chitosan-collagen sponge (CCS) for potential wound dressing applications. CCS fabricated by 3.0% chitosan mixture with 1.0% type I collagen (7:3(w/w)) through freeze-drying. Then the prepared evaluate its properties series of tests. new-made demonstrated safety toward NIH3T3 cells. Furthermore, showed significant surround inhibition zone than em...

Type I collagen gels are routinely used in biophysical studies and bioengineering applications. The structural and mechanical properties of these fibrillar matrices depend on the conditions under which collagen fibrillogenesis proceeds, and developing a fuller understanding of this process will enhance control over gel properties. Turbidity measurements have long been the method of choice for m...

There are conflicting views on whether collagen X is a purely structural molecule, or regulates bone mineralization during endochondral ossification. Mutations in the human collagen alpha1 (X) gene (COL10A1) in Schmid metaphyseal chondrodysplasia (SMCD) suggest a supportive role. But mouse collagen alpha1 (X) gene (Col10a1) null mutants were previously reported to show no obvious phenotypic cha...
