Bone loss after spinal cord injury leads to increased fragility of bone and subsequent risk for low-trauma fractures in the sublesional parts of the body. Although in such injuries upper limbs are normally innervated, bone loss may occur in the upper extremities. The present study was designed to determine the systemic effects of spinal cord injury on the fracture healing of upper limbs in rabb...
Traditional exercise programs seem to be less osteogenic in the mature and post-mature skeleton compared to the young skeleton. This is likely because of the decline in sensitivity of bone to mechanical loading that occurs with advancing age. Another factor contributing to the apparently diminished benefit of exercise in older adults is failure of widely used measurement techniques (i.e., DXA) ...
Bone fractures usually happen during car accident and sport trauma. Different factors influence bone healing such as malnutrition and smoking. Apart from addiction which is an important individual, social, and cultural problems morphine has several effects on body physiology and immune system .This study is performed to assess the effect of morphine dependency on bone healing and has not been r...
Introduction: Increasing hematological diseases along with increased use of microwaves in different systems proposed possible correlation between them. Age of exposure to wave is also an important factor. This study was conducted to evaluate the effect of radiation leakaged from microwave oven on hemopoitic bone marrow cells at pre and post pubertal. Methods: Fourteen male mature (2 months old...
OBJECTIVE To investigate the ability of a bone growth factor mixture and bone marrow cells to repair a critical size defect of the rat mandibular body. DESIGN Prospective, randomized controlled trial. SUBJECTS Thirty-seven male Fischer rats. INTERVENTIONS Critical size defects 4 mm in diameter were created in the left mandibular bodies of the rats. The defects were filled with a bone marr...
Bone homeostasis is maintained by the balanced action of bone-forming osteoblasts and bone-resorbing osteoclasts. Multinucleated, mature osteoclasts develop from hematopoietic stem cells via the monocyte-macrophage lineage, which also give rise to macrophages and dendritic cells. Despite their distinct physiologic roles in bone and the immune system, these cell types share many molecular and bi...
