various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...
background patients with thalassemia major and intermedia are susceptible to osteopenia and osteoporosis. the mechanism of osteoporosis in these patients is multifactorial. transfusion related iron overload in endocrine organs leads to impaired growth hormone secretion, diabetes mellitus, hypothyroidism, hypoparathyroidism, lack of sex steroids and vitamin d deficiency that contribute to impair...
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...
chronic recurrent multifocal osteomyelitis (crmo) is an inflammatory bone disease usually affecting children. a 9-year old boy presented with recurrent lower extremities pain and discomfort lasting for two years. in every time, symptoms vanished after several weeks. the patient received antibiotics only in one period of bone pain. in other occasions the patient didn’t received any antibiotics. ...
objective: oral lesions are among the important reasons for seeking dental care. being frequently encountered, giant cell lesions form an important group of oral lesions. the epidemiologic data on these lesions, however, is scarce in iran. the present study investigated epidemiological and demographic characteristics of giant cell lesions in oral biopsies done in one of the largest oral patholo...
aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...
the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...
A number of murine models are used to mimic the pathology of breast cancer. Tissue inoculation and cell inoculation using orthotopic implantation (OS) and subcutaneous implantation (SQ) are commonly used to generate murine models to investigate cancer. However, limited information is available in regard to the variations of these methods. The present study compared growth, metastasis, survival ...
Forest resource information has a hierarchical structure: individual tree attributes are summed at the plot level and then in turn, plot-level estimates are used to derive stand or large-area estimates of forest resources. Due to this hierarchy, it is imperative that individual tree attributes are measured with accuracy and precision. With the widespread use of different measurement tools, it i...
