objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...

Bone marrow examination is commonly used in the evaluation of hemato-oncological disorders and in patients with cancer of solid organs to detect metastases. This study reviews clinical, hematological and pathological data of nine cases with bone marrow metastases from solid tumors. The significance of bilateral bone marrow aspirations and biopsy has also been highlighted. Out of 784 bone marrow...

background: bone marrow transplant (bmt) recipients are prone to bacterial, viral and fungal infections. bacterial infec­tion is considered as one of the common and serious complications in bone marrow transplant recipients. the aim of this study was to determine the rate of bacterial infections in bone marrow transplant recipients. methods: fifty-two blood and 25 catheter samples were obtained...

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 ...

chronic myelogenous leukemia (cml) is a stem cell disorder sometimes associated with lymphoproliferative disorders. cml may precede a lymphoproliferative disorder. there are a few reports showing associating of cml with multiple myeloma and we report a known cml case that transformed into a full-blown multiple myeloma. this patient had more than 69% of infiltrating myeloma cells in her bone mar...

A normal bone marrow microenvironment plays a very important role in the normal functioning of hematopoietic stem cells. Once disturbed, this microenvironment can become favorable for the occurrence of blood disorders, cancers, and other diseases. Therefore, further studies on the bone marrow microenvironment should be performed to reveal regulatory and stem cell fate determination mechanisms a...

osteoarthritis (oa) is a prevalent chronic disease impacting on quality of life and has societal and economical burden increasing with age. yet, no confirmed pharmacological, biological or surgical therapy could prevent the progressive destruction of oa joint. mesenchymal stem cells (mscs) with immunosuppressive activities emerged a potential therapy. we describe a magnetic resonance images (mr...

different types of actinomyces spp isolated from the oral cavity of human in healthy as well as in pathological state. internally it is only found in association with pathological organs. recently actinomyces naeslundii has been isolated from blood culture of a leukemic patient. present studies indicate the association of this microorganism with cells obtained from bone marrow by punction in mo...

introduction: silymarin is obtained from silybum marianum (milk thistle), an edible plant that has long been used medicinally for the treatment of liver-related disorders. silymarin is a powerful hepatoprotective and antioxidant but the anticlastogenic activity, which is an important aspect of its cancer chemoprevention is not known hence the present investigation was carried out to study its a...
