conclusions due to the high risk of non-:union: and mal-:union: in humerus shaft fracture, and because applying this simple and inexpensive technique significantly decreased these complications, injecting autologous bone marrow grafts is recommended for accelerating :union: in cases of humerus fracture. results the mean time of :union: was 8.54 ± 3.41 weeks for the individuals followed in the s...

conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...

background: previous investigations have revealed, cimetidine, a histamine h2-receptor antagonist, show radioprotective effects against gamma- and neutron-induced micronuclei in bone marrow erythrocytes. in this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine h2-receptor antagonists, was investigated. materials and methods : balb/c m...

the relationship between the way in which normal hemopoietic stem cells respond to irradiation alone or in the presence of bleomycin sulfate (blm-s) and actinomycin 0 (act-d) was investigated. single doses of blm-s at 0.3 mg/kg and act-o at 0.10 mg/kg body weight were injected intravenously 1-6 hours prior to whole body irradiation and treatment was repeated twice more with time intervals. when...

background: pancytopenia is a manifestation of a wide range of disorders. the main prognostic factor for predicting outcome and response to treatment is based on the underlying cause. to detect the root cause of this problem, depending on other accompanied signs or symptoms, the need for bone marrow examination and other advanced work ups is different at least at the practical level. this study...

Background: The purpose of this study was to find the accurate absorbed dose in the femur bone marrow during the X-ray radiography for constant mAs and AEC techniques. Materials and Methods: The DOSXYZnrc was used to simulate radiation doses in two human femurs during diagnostic radiography. EGSnrc phantoms produced from actual CT images of human femurs were modified by adding seven micrometre ...

background :cell-based therapies can be used to treat neurological diseases and spinal cord injuries. the aim of this study was to assess the clinical outcome of bone marrow derived mononuclear cells (bm-mncs) transplantation in patients with spinal cord injuries.   method s: following a systematic review to detect clinical intervention studies, a meta-analysis was done for pooling data to esti...

background : the most frequent use of diatoms in forensic science is the diagnosis of death due to drowning. the basic principle of diatom test in drowning is based on the inference that diatoms are present in medium where drowning took place and the inhaled water enters the alveolar spaces of lungs and penetrates from the alveoli into the blood circulation, thus microscopic unicellular algae c...

this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...

background: since 1996 the assessment of environmental gamma radiation dose in residential areas of iranian towns and cities has been accomplished for 10 counties. as a practical method and based on the results of a pilot study, in order to attribute the final results to the whole residential area of a town five stations were selected for every town. the location of individual station was studi...
