Our previous studies have indicated the presence of a macromolecular inhibitor of in vitro mineral growth, as well as a mineral nucleational agent in extracellular matrix fluid aspirated by micropuncture methods from epiphyseal hypertrophic cell cartilage. In this report, new miniaturized methods were used to extract proteinpolysaccharide complexes (PPC) from cartilage, to isolate a light fract...

Shark (Carcharhinus sorrah) is a fish whose entire endoskeleton composed of cartilage. Fish cartilage widely used for treatment because shark (SC) contains glucosamine (GS) and chondroitin sulfate (CS) compounds. This study aims to determine the benefits derived from SC extract on lizard tail regeneration. The was initiated by testing characteristics ointment which included tests spreadability,...

diced rib cartilage is an acceptable option in severe nasal deformities. we present our preliminary experience in kamc in nasal septoplasties using the autologous diced costal cartilage. this is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years. all our patients needed autologous diced rib cartilages. twelve were wrapped with tempora...

Background: Sharks get cancer rarely. A major difference between these animals and other species is that sharks have a great amount of cartilaginous tissue. Immunomodulatory effects of the cartilage of some species (cow) have been proved. Because the immune system has a major role in the defense of the body against cancer, we studied the effects of shark cartilage on the mouse and human immune...

background: previous studies have shown that galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones.   objective: in the present work, the expression pattern of galectin-3 in normal and various grades of osteoarthritic (oa) human articular cartilage has been studied.   methods: using immunohistochemistry and standard we...

Background: This work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. It is known that elucidation of molecular events under Interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...

bone has a capability to repair itself when it is fractured. repair involves the generation of intermediatetissues, such as fibrous connective tissue, cartilage and woven bone, before final bone healing can occur. theprocess of cartilage-to-bone transition (cbt) is a key for the achievement of rigid bone healing duringfracture repair. we tested this potential for elastic cartilage using a long ...

The delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC) method allows for both qualitative and quantitative measurement of the spatial distribution of glycosaminoglycan [GAG] in excised cartilage. The objective of this study was to determine the effect of paraformaldehyde fixation on dGEMRIC measurements. Five bovine and seven human cartilage pieces were punched into 5...
