BACKGROUND Chondrocytes respond to biomechanical and bioelectrochemical stimuli by secreting appropriate extracellular matrix proteins that enable the tissue to withstand the large forces it experiences. Although biomechanical aspects of cartilage are well described, little is known of the bioelectrochemical responses. The focus of this study is to identify bioelectrical characteristics of huma...

Osteoarthritis is a common chronic and progressively degenerative joint condition. The stem bark of Eucommia ulmoides Oliver (a member of the Eucommiaceae family), which is also known as Du-Zhong, is a traditional Chinese medicine commonly used for the treatment of rheumatoid arthritis. However, the mechanisms underlying the effects of Eucommia in the treatment of arthritis of the knee require ...

Cryptolepis buchanani Roem. & Schult. is widely used in folk medicine in Southeast Asia for treating muscle tension and arthritis. This study aimed to investigate an analgesic activity of the methanol extract of C. buchanani (CBE) in acetic acid-induced writhing response in mice, and to examine its anti-inflammatory activity in ethyl phenylpropiolate- (EPP-) induced ear edema and carrageenan-in...

LEVANDER (1938) has shown that an alcohol extract prepared from bone can, when injected into rabbit muscle, induce there cartilage and bone cells. This observation has been confirmed by several investigators (Annersten, 1940; Bertelsen, 1944; Lacroix, 1945; Levander, 1949; Willestaedt, Levander & Hult, 1950). Of these, Bertelsen has shown in addition that not only is an extract prepared from bo...

AIM Shark cartilage has anti-inflammatory, analgesic, anti-angiogenic, anti-tumoral, and immunomodulatory properties. We studied the effect of shark cartilage on the healing of colonic anastomoses, which are among the gastrointestinal system anastomoses that most commonly cause leakage. MATERIAL OF STUDY Rabbits were divided into two groups of seven as the study and control groups. A normal d...

In order efficiently to target therapies intending to stop or reverse degenerative processes of articular cartilage, it would be crucial to diagnose osteoarthritis (OA) earlier and more sensitively than is possible with the existing clinical methods. Unfortunately, current clinical methods for OA diagnostics are insensitive for detecting the early degenerative changes, e.g., arising from collag...

Purpose WIN-34B is a butanol fraction extract from the mixture of two oriental herbs, the dried Lonicera japonica flowers and the root of Anemarrhena asphodeloides. In previous studies, we indentified that WIN-34B has analgesic, anti-inflammatory, gastroprotective and safety effects. In this study, we measured the major components and investigated the efficacy of WIN-34B on cartilage protection...

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...

Hyaluronic acid-binding region and trypsin-link protein were prepared from bovine nasal cartilage proteoglycan complex after trypsin digestion. Binary complexes were reformed between trypsin-link protein and hyaluronic acid-binding region or hyaluronate. Upon trypsin treatment of these complexes, two fragments deriving from trypsin-link protein were characterized. One of them, of 20 kDa, corres...
