Class 13 - Polycythemia & Leukemia Flashcards
polycythemia
increase in rbcs
chronic myelogenous leukemia
excessive development of mature neoplastic GRANULOCYTES
purpura
small blood vessels burst causing blood to pool just under the skin
philadelphia chromosome
found in chronic myelogenous leukemia
natural killer cells
type of cytotoxic lymphocyte that is used in host-rejection of tumors and virally infected cells
hematocrit
% of total blood volume that is made up by the rbcs
proto-oncogene
regulate normal cellular processes
leukemia
cancer of blood-forming tissues
chronic lymphocytic leukemia
production of inactive mature lymphoCYTES
pancytopenia
anemia, leukopenia, thrombocytopenia
plasma cells
white blood cells that originate in the lymphoid organs
lactate dehydrogenase level
enzyme involved in energy production
chemotherapy
drugs that kill cells directly by damaging DNA or interrupting mitosis
oncogene
mutated gene
acute mylegenous leukemia
uncontrolled prolifertion of myeloblasts
petechiae
spotting
rubor
redness of the skin
b lymphocytes
produce antibodies
neutrophils
type of WBC that helps heal damaged tissues and resolve infections
neutropenia
decrease in the number of neutrophils
tumor suppressor gene
suppress growth of tumors
acute lymphocytic leukemia
lymphoblasts
ecchymosis
discolouration of the skin due to bleeding underneath
pruritis
itchy, dry skin
t lymphocytes
directly kill microorganisms
hemoglobin
indirect measurement of the amount of rbcs in the blood
stem cell transplant
to eliminate leukemic cells from the body by giving donor stem cells
