Background: Rheumatoid arthritis (RA) is the most common inflammatory arthritis affecting 0.5 to 1% of the general population worldwide. The cause of RA remains unknown. In active RA, bone turnover markers change in serum and urine before the appearance of erosions in radiography. In this study, we compared RA activity index with bone turnover marker levels in serum of RA patients. Methods:...
mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...
bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...
Transiliac biopsies from 34 female patients with corticosteroid treated chronic active hepatitis have been examined to determine the contributions made by decreased bone formation and increased bone resorption to bone loss associated with this condition and to determine the structural basis of the bone loss. Mean wall thickness was significantly reduced when compared with control values (p less...
many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. this study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (e-bmg) in rabbit. e-bmg was prepared from tibia and femur of 4 deutsche-poland rabbits with average ages of 4-6 months. the prepared e-bmg was implanted in right incisor teeth pulps of...
introduction : efforts are being made to improve the efficacy of biomaterials used as bone substitutes for bone regeneration in the oral and maxillofacial region. graft materials have been recently produced in iran; however, studies are required to confirm their efficacy. this study aimed to compare the histomorphometric results of using mineralized allografts produced by the hamanandsaz baft k...
Comparative study of bone and lamellar bone formation in Peripheral Giant Cell Granuloma and Peripheral Ossifying Fibroma Dr. SH. Ghasemi Moridani* - Dr. H. Mahmoodi Chenari* *-Assistant Professor of Oral and Maxillofacial Pathology Dept.-Faculty of Dentistry-Guilan University of Medical Sciences. **- Dentist. Background and Aim: Peripheral Giant Cell Granuloma (PGCG) and peripheral ossifying f...
background: it has been stated that the bone allografts from different tissue banks may lead to various amount of bone induction, so the aim of this study was to evaluate bone regeneration of three demineralized allografts both histologically and histomorphometrically in rabbits calvaria bone defects. materials and methods: in this double-blind randomized experimental animal study, 32 critical ...
BACKGROUND Bone metastases are highly frequent complications of breast cancers. Current bone metastasis treatments using powerful anti-resorptive agents are only palliative indicating that factors independent of bone resorption control bone metastasis progression. Autotaxin (ATX/NPP2) is a secreted protein with both oncogenic and pro-metastatic properties. Through its lysosphospholipase D (lyso...
