Tissues bone marrow

It has been found that the effects of radiation on some vital tissues (bone marrow, spleen, blood and reproduction cells) are seen more quickly than on other tissues. Because these tissues grow faster than others, any type of damage in the cells can be easily and quickly transferred into new cells. All cells can be affected by this chain reaction. This can result in tumors, which explains the carcinogenic effect of radiation.

The t(14 18) translocation in follicular and diffuse large B-cell lymphoma can be detected by PCR-based molecular methods using consensus primers to both bd-2 and JH regions. The PCR-based method allows the use of smaller amounts of DNA to detect this translocation, even low molecular DNA extracted from formalin-fixed paraffin-embedded tissue, bone marrow or fine needle aspiration. This method is efficient for the primary diagnosis of follicular lymphoma or to detect minimal residual tumor cells that are below the limit of detection using conventional diagnostic methods espedally after chemotherapy or bone marrow transplantation. 

Method The method used is mRNA extraction from tissue, bone marrow, peripheral blood or body fluids, followed by RT-PCR. 

Adipose tissue is present in regional depots such as subcutaneous upper and lower body and visceral fat [11]. Apart from these classic depots fat is present in most other tissues, for example, connective tissue, bone marrow, liver and muscle. The picture is further complicated by the fact that within each tissue fat is distributed in compartments. In muscle for instance fat is present intramyocellularly, intermyocellularly and inter-muscularly. Under physiological conditions lipolysis... 

Stroniium-90 is chemically similar to calcium, and tends to deposit in bone and blood-forming tissue (bone marrow). Thus, strontium-90 is referred to as a "bone seeker." Internal exposure to Sr-90 is linked to bone cancer, cancer of the soft tissue near the bone, and leukemia. 

In the mammalian (including the human) organism, the most sensitive cells are the circulating small lymphocytes and the internal layer of vessels, the endothelial cells. Tissues in decreasing order of radiation sensitivities are the lymphatic tissue, bone marrow, epithelia of stomach and intestines, the gonad cells, the basal layer of skin, the glandular tissues, liver, the connective tissue, muscle, and the nervous tissue. 

Extremely high Hematopoeitic tissue Bone marrow Spleen Lymph nodes Thymus Almost immediately (<15 min) after a dose of 50 R, white cells die. Red cell population drops after 14-21 days. Symptoms include malaise, anemia, susceptibility to infection. 

In order to understand the two wave phenomena, it is necessary to understand the acoustic properties of soft tissue (bone marrow). However, there are a few researches of bone marrow. The objective of this study is then to investigate ultrasonic properties in the bone marrow, using an ultrasonic pulse technique.
