Objective: Dry tap is usually defined as a “failure to obtain bone marrow on attempted marrow aspiration”. The diagnosis and management of many haematological diseases depends on examination of the bone marrow, which involves two separate specimens i.e. a cytologic and a histologic preparation. The purpose of this study was to document the causes of dry tap and importance of bone marrow biopsy....

Introduction Marrow biopsy by surgical trephine is an older procedure than needle aspiration. It is only since the late 1950s that core needle biopsy of the bone marrow has been widely used. Since that time, it has had a considerable effect on diagnostic haematology, pathology and oncology. Wide acceptance is associated with the introduction of a simple procedure using the Jamshidi needle to im...

background:  renal transplantation is the best choose in the end stage renal disease (esrd), and acute rejection and graft dysfunction remain major challenges in the worldwide, even with the advent of new immunosuppressive drugs. the novel cell-based anti-rejection treatments have been studied by using different stem cell sources. in this study, transplantation of autologous-bone-marrow-derived...

Bone marrow aspiration (BMA) and bone marrow trephine biopsy are important procedures for the diagnosis of hematological malignancies and nonmalignant diseases in children. During BMA, bone marrow particles are obtained for analysis including microscopic morphologic evaluations and differential counts. During a trephine biopsy, a core of bone marrow is obtained and processed for the evaluation ...

Myeloma is the most common primary malignancy affecting skeletal system. Most of patients are presented and diagnosed late at disease process, so early detection very beneficial for patient management choice treatment. Multiparametric MRI with added value diffusion weighted images together PETCT had been diagnosis, treatment follow up after The study was conducted on 24 bone marrow biopsy aspir...

Serial sampling of the cellular composition of bone marrow (BM) is a routine procedure critical to clinical hematology. This protocol describes a detailed step-by-step technical procedure for an analogous procedure in live mice which allows for serial characterization of cells present in the BM. This procedure facilitates studies aimed to detect the presence of exogenously administered cells wi...
