Better understanding of bone growth and regeneration mechanisms within periosteal tissues will improve understanding of bone physiology and pathology. Macrophage contributions to bone biology and repair have been established but specific investigation of periosteal macrophages has not been undertaken. We used an immunohistochemistry approach to characterize macrophages in growing murine bone an...

INTRODUCTION The periosteum serves as a stabilizing boundary membrane to the bone it envelops and is known to contain pluripotent and osteochodroprogenitor cells. Periosteal cells have been shown to have the capacity to infill critical sized defects with proliferative woven bone within weeks of injury [1,2]. Critical sized defect healing has been shown to be maximal when cells egress from perio...

Introduction: Many pathological processes such as infections, intoxications, and malignant tumors were spread through the lymphatic vessels of thoracic cavity. In present study, we investigated anatomy lymph nodes cavity in humans.
 Materials methods: The examination was performed on 60 cadavers fetuses (25), newborn children (14), (11), adults (10). Lymphatic rib periosteum, costovertebra...

Fracture healing is a complex process that involves presence of osteoprogenitor cells and growth factors. Therefore, the integrity of the fracture site surrounding tissues including periosteum is necessary in order to provide the resources for bone regeneration. The purpose of this review is to organize and synthesize the relevant information regarding periosteum and fracture repair. Periosteum...

The periosteum is a thin layer of connective tissue that covers the outer surface of a bone in all places except at joints (which are protected by articular cartilage). As opposed to bone itself, it has nociceptive nerve endings, making it very sensitive to manipulation. It also provides nourishment in the form of blood supply to the bone. The periosteum is connected to the bone by strong colla...

PURPOSE Periosteum provides essential cellular and biological components necessary for fracture healing and bone repair. We hypothesized that augmenting allograft bone by adding fragmented autologous periosteum would improve fixation of grafted implants. METHODS In each of twelve dogs, we implanted two unloaded cylindrical (10 mm x 6 mm) titanium implants into the distal femur. The implants w...

INTRODUCTION The periosteum may have an important function of new bone formation because of the abundant blood supply and the presence of osteoprogenitor cells. Periosteal cells have also been used for bone and cartilage formation. Though there have been many studies about the osteogenesis using periosteum, and osteogenic activity of osteoprogenitor cells such as mesenchymal stem cells(MSCs), l...

OBJECTIVE To reinvestigate the innervation pattern of the dura mater of rat and human middle cranial fossa, the morpho-functional substrate of headache generation, and adjacent extracranial tissues with neuronal in vitro tracing. BACKGROUND This study was initiated by recent structural and functional findings of meningeal afferent fibers which innervate the cranial dura mater and may project ...

The sudden hemodynamic disturbance in the perioperative period can occur because of various surgical and anesthetic reasons but hemodynamic collapse due to noxious stimulus of periosteum stripping has not been described. We report two cases of severe hypotension and bradycardia during periosteum stripping in orthopedic surgery under subarachnoid block even though the block level was adequate. I...
