    leukocytes that do have granules within the cytoplasm, include lymphocytes & monocytes
  3. anaphylaxis
    • in blood transfusion
    • sensitivity to donor plasma proteins.
    • infusion of IgA proteins to IgA-deficient recipient who has developed IgA antibody
  4. anaplasia
    • Reversion of cells to an immature or a less differentiated form, as occurs in most malignant tumors.
    •  
  5. anemia
    reduction below normal of the number of erythrocytes, quantity of hemoglobin, or the volume of packed red cells in the blood
  6. antigens
    any substance capable of inducing a specific immune response and of reacting with the products of that response
  7. antimetabolite
    a drug or other substance that is an antagonist to or resembles a normal human metabolite and interferes with its function in the body, usually by competing for its receptors or enzymes
  8. aplastic anemia
    a disease in which the pt has peripheral blood pancytopenia (decrease of all blood cell types-RBCs, WBCs, & platelets) & hypocellular bone marrow
  9. bacteremia
    invasion of bloodstream by bacteria
  10. blast cells
    blood cells in early stage of development
  11. benign
    not malignant, favorable for recovery
  12. carcinogens
    any substances that cause cancer
  13. carcinoma
    malignant epithelial tumor
  14. cyst
    an abnormal closed epithelium-lined cavity in the body, containing liquid or semisolid material.
  15. cytology
    the study of cells, their origin, structure, function, and pathology.
  16. DIC
    disseminated intravascular coagulation
  17. dissemination
    the spread of pernicious process
  18. dysplasia
    alteration in size, shape, and organization of adult cells
  19. ecchymosis
    a hemorrhagic spot, larger than a petechia, in the skin or mucous membrane, forming a flat, rounded or irregular, blue or purplish patch.
  20. effusion
    The escape of fluid from the blood vessels or lymphatics into the tissues or a cavity
  21. endogenous
    produced, orginated within an organism, tissue, cell
  22. epistaxis
    nose bleeding
  23. erythocytes
    RBCs
  24. erythrocytopenia
    a deficiency or decrease in number of erythrocytes.
  25. erythropoiesis
    formation or production of RBCs
  26. glossitis
    inflammation of the tongue
  27. granulocytes
    leukocytes that have granules within the cytoplasm
  28. hematocrit
    the percentage of total blood volume occupied by RBCs
  29. hemoglobin
    the oxygen-carrying protein, give the red color of the RBCs
  30. hemolysis
    destruction of RBCs by monocytes & macrophages removes abnormal, defective, damaged, & old RBCs from circulation
  31. hemostasis
    a sequence of responses to stop blood loss from a damaged blood vessel. Three mechanisms are involved: vascular spasm, platelet plug formation, and blood clotting.
  32. histology
    study of minute structure of tissues and organs in relation to their function.
  33. leukopenia
    reduction of the number of leukocytes in the blood below about 5000/uL
  34. lymphangiogram
    the film produced by lymphangiography
  35. lymphocytes
    a kind of agranulocytes, major combatants in immune responses
  36. malaise
    a vague feeling of discomfort
  37. monocytes
    a type of agranulocytes, take longer to reach a site of infection than do neutrophils, but they arrive in large numbers. Upon their arrival, monocytes enlarge and differentiate into wandering macrophages, which phagocytize many more microbes than can neutrophils. They also clean up cellular debris following an infection.
  38. nadir
    The lowest value of blood counts after chemotherapy.
  39. neoplasm
    tumor; any new and abnormal growth, specifically one in which cell multiplication is uncontrolled and progressive. Neoplasms may be benign or malignant.
  40. neutrophils
    a type of WBCs, active in phagocytosis, respond most quickly to tissue destruction by bacteria. After engulfing a pathogen during phagocytosis, a neutrophil unleashes several destructive chemicals to destroy the ingested pathogen.
  41. occult
    not visible, or easily detected
  42. oncogene
    A gene that causes the transformation of normal cells into cancerous tumor cells, especially a viral gene that transforms a host cell into a tumor cell.
  43. oncogenesis
    formation, production of tumors
  44. oncology
    the study of tumors
  45. pallor
    paleness of the skin
  46. pancytopenia
    a marked reduction of RBCs, WBCs, platelets in the blood
  47. plasma
    the watery straw-colored fluid part of the lymph and the blood in which the leukocytes, erythrocytes, and platelets are suspended
  48. platelets
    are thrombocytes, initiate the clotting process by producing an initial platelet plug in the early phases of clotting process
  49. purpura
    A large, purplish-red circle on the skin. Caused by the leakage of blood out of a vessel and under the skin. medium size, larger than pinpoint petechiae but smaller than ecchymosis
  50. rad
    abbreviation for radiation absorbed dose.
  51. radiation
    energy transmitted by waves through space or through some medium; usually referring to electromagnetic radiation, when used without a modifier
  52. reticulocyte
    an immature erythrocyte
  53. reverse isolation
    use of protective equipment is required to prevent transmission of infection to the patient. Handwashing, gowning, gloving, sterilization, or disinfection of materials brought into the area and other details of housekeeping vary with the reason for the isolation and the usual practices of the hospital.
  54. septicemia
    blood poisoning; systemic disease associated with the presence and persistence of pathogenic microorganisms or their toxins in the blood
  55. stomatitis
    Inflammation of the mucous lining of any of the structures in the mouth, which may involve the cheeks, gums, tongue, lips, and roof or floor of the mouth
  56. thrombocytes
    another name for platelets
  57. thrombocytopenia
    a reduction of platelets below 150,00/uL
