    Leukemia Leukemia strikes all ages and both sexes. In 1995 approximately 20, 400 people died from Leukemia. The all time five year survival rate is 38%. This rate has gone to 52% in the mid 1980's. Approximately 25, 700 cases were reported in 1995 alone (American Cancer Society-leukemia, 1995). Leukemia is a form of cancer in the blood cells. Most forms of Leukemia occur in the white blood cells. These abnormal cells reproduce in large quantities and look and perform differently than normal cel...
  • Leukemia Blood Cell

    Leukemia is a disease characterized by the formation of abnormal numbers of white blood cells, for which no certain cure has been found. Leukemia is also conditions characterized by the transformation of normal blood-forming cells into abnormal white blood cells whose unrestrained growth overwhelms and replaces normal bone marrow and blood cells. Leukemias are named according to the normal cell from which they originate, such as Lymphocyte Leukemia. Lymphocyte Leukemia is where a Lymphocyte cell...

    INTRODUCTION A child is born everyday and without realizing it, the material that is routinely discarded after the birth could one day be life saving for that person, someone else in the family, or even a complete stranger. This material is the umbilical cord, and the blood contained within their vessels. One may wonder, why is this blood so important? Medical research has discovered that the residual umbilical cord blood contains stem cells. These cells are the building blocks that the body use...
  • Stem Cells The Holy Grail Of Medical Research
    1,470 words
    Few scientific issues in recent years have managed to draw as much attention, both scientific and otherwise, than stem cell research. I was first introduced to the term 'stem cells' when I was in high school, and since then, I have had a keen interest in the direction science is taking them. When considering medical research as a whole, stem cells appear to have the makings of a 21 st century medical revolution a la discovery of antibiotics. The open-ended nature of stems cells has been recogniz...
  • Leukemia Bone Marrow
    460 words
    Leukemia Leukemia is a disease that affects blood-forming tissues, mainly bone marrow. Leukemia also affects the lymph glands and spleen. Leukemia causes the body to produce an extreme amount of abnormal white blood cells. This causes infections because the abnormal cells cannot stop infections like the normal cells do. Leukemia also causes anemia. Anemia is a disease in which the body makes less blood cells. This happens because the leukemic cells crowd the system. Leukemia also causes excessi...

    Lymphoma Lymphoma or lymphatic cancer is a very serious and life threatening disease. In this country there is an estimated 63, 900 new cases, 7, 100 of which are Hodgkin's lymphoma as opposed to non-Hodgkin's lymphoma. Since around the 70's the occurrence of non-Hodgkin's lymphoma has almost doubled while the occurrence of Hodgkin's disease has declined. (Steen, 1993) Lymphoma is the name given to a cancer that infects the lymphatic system. In a case of lymphoma the lymphatic system has cells t...
  • Stem Cells Blood Cord Umbilical
    634 words
    After a typical delivery the umbilical cord and the blood within it is discarded. Now researchers have discovered that this blood contains valuable stem cells which can be used in the treatment of several blood disorders. Stem cells are simply undeveloped cells that develop into platelets or red and white blood cells. Stem cells will continue to produce blood cells for an indefinite period of time after transplantation. Until the discovery of stem cells in umbilical cord blood and placentas, bo...
  • The Immune System Lymphocytes Body Cells
    739 words
    The Immune System The immune system is a group of cells, molecules, and tissues that help defend the body against diseases and other harmful invaders. The immune system provides protection against a variety of potentially damaging substances that can invade the body. These substances include disease-causing organisms, such as bacteria, fungi, parasites, and viruses. The body's ability to resist these invaders is called immunity. A key feature of the immune system is its ability to destroy foreig...

    Should parents pay a blood bank to store the blood from their newborn baby's umbilical cord and placenta, in case that child or another family member ever needs it to treat cancer or leukemia Expectant parents are being urged to do so by companies that have sprung up during the past few years to sell cord-blood banking as a form of "biological insurance" against such dreaded diseases. The pitch is based on reports in medical journals, such as a major study published last week in the New England ...

    Stem cells are primitive cells found in embryos, fetuses, and recently adults that can grow into 210 types of cells in the body. James A. Thomson, an embryologist at the University of Wisconsin, and John D. Gearhart of the Johns Hopkins University School of Medicine announced on Thursday, November 8 1998 that they and their colleagues had isolated the cell. Scientists have tried for years to find stem cells because of their great medical value. Diseases such as Diabetes, Bone Marrow Cancer, Chr...
  • The Immune System Killer Cell
    1,690 words
    The immune system is composed of many interdependent cell types that collectively protect the body from bacterial, parasitic, fungal, viral infections and from the growth of tumor cells. Many of these cell types have specialized functions. The cells of the immune system can engulf bacteria, kill parasites or tumor cells, or kill viral-infected cells. Often, these cells depend on the T helper subset for activation signals in the form of secretions formally known as, lympho kines, or more specific...
  • Aplastic Anemia Versus Host
    1,431 words
    Aplastic anemia is a disease of the bone marrow the organ that produces the body's blood cells. Approximately two thousand people in the U. S. are diagnosed each year with aplastic anemia. The symptoms of aplastic anemia are fatigue, bruising, infections, and weakness. Although these symptoms are much like those associated with leukemia, aplastic anemia is not a form of cancer. In patients with aplastic anemia the bone marrow stops producing, or produces too few red blood cells, white blood cel...
  • Circulatory System A Tissue Fluid

    FORMATION OF TISSUE FLUID AND EXCHANGE OF MATERIALS IN THE CAPILLARY NETWORK In a capillary network, two opposing forces mainly determine the movement of fluid between the blood and tissue fluid: (1) the hydrostatic pressure difference and (2) the osmotic potential difference between the blood and the tissue fluid. In the part of the capillary network near the arterial end, blood pressure is much higher than that of the tissue fluid so that the difference in hydrostatic pressure exceeds the osmo...

    How does the body achieve the functional silencing of antigen reactive clones The central tenet of the immune system is the ability to recognise and remove non-self components without affecting self components. The T cells and B cells of the immune system express a vast repertoire of antigen receptors. It is thought that the germline TCR repertoire is composed of in the region of at least 109 different specificities. Considering the potential number of antigens that may be bound by these recepto...
  • Leukemia Bone Marrow

    According to the Cancer Book from the American Cancer Society, Leukemia is a cancer of the blood. It was first identified as a new disease in around 1830 in Germany. The scientific term, "leukemia," comes from the Greek words that mean "white blood." The disease is described as a cancerous disorder not just of the blood itself, but also of the organs that produce the blood cells in the body. The organs are mainly the bone marrow and the lymph system, where normal red and white cells, lymph cells...

    Human Cloning: Controversial Issues Paper In the article that I chose there are two opposing viewpoints on the issue of "Should Human Cloning Ever Be Permitted?" John A. Robertson is an attorney who argues that there are many potential benefits of cloning and that a ban on privately funded cloning research is unjustified and that this type of research should only be regulated. On the flip side of this issue Attorney and medical ethicist George J. Annas argues that cloning devalues people by depr...

    'A fundamental requirement of the immune system is that it destroy, eliminate or inactivate all foreign viruses, bacteria and parasites without destroying self-cells or molecules' (Lydyard 2000). This is carried out by B and T cells, which are able to distinguish what is 'foreign' (i. e. non self) from what is self. They are responsible for the adaptive immune response and have developed a number of different mechanisms in the central and peripheral lymphoid organs that underlie the basis for se...
