Leukocytes (Leukopoiesis, Leukemia, other Diseases) Flashcards
normal M:E ratio
3:1 (2:1 to 4:1)
days of maturation (IN THE BONE MARROW) of leukocytes
14 days
start of the formation of primary granules
promyelocyte
start of the formation of secondary granules
myelocyte
WBC precursor that has an indented kidney shaped nucleus
metamyelocyte
primary granules
“Cats Are My Elastics to Acids”
cationic antibacterial proteins arylsulfatse myeloperoxidase elastase acid phosphatase acid hydrolase
WBC precursor that has the highest number in the bone marrow
metamyelocyte/juvenile cells
secondary granules specific to neutrophils
“CALL”
collagenase
alkaline phosphatase
lyzozyme
lactoferrin
secondary granules specific to eosinophls
major basic proteins
secondary granules specific to basophils
heparin
histamine
random locomotion is AKA
chemoKINESIS
directed locomotion is AKA
chemoTAXIS
neutrophil enzyme responsible for respiratory burst or oxidative burst
myeloperoxidase
neutrophil enzyme that degrades the bacterial cell wall
lyzozyme or muramidase
neutrophil enzyme that competes with bacteria for iron
lactoferrin
neutrophil life span (IN THE CIRCULATION)
9-10 days
major function of basophils
hypersensitivity reactions such as allergic asthma and delayed hypersensitivity reaction
granule responsible for the metachromicity of basophils
heparin
granules that mediate hypersensitivity reaction
histamine
WBC that is metabolically more active than the neutrophil
eosinophil
an increase in ACTH would cause:
decreased eosinophil count
functions of major basic proteins
against helminths
neutralize histamine
neutralize heparin
induce heparin
test that will evaluate normal adrenal function
Thorn’s test/eosinophil depression test
sample collection for Thorn’s test
1) Basal state
2) 4 hours after ACTH administration
3) compared values
normal values of Thorn’s test
ACTH should DECREASE eosinophil count by 50%
> 50%: Cushing’s (HYPER)
<50%: Addison/s (HYPO)
largest cell in the peripheral blood
monocyte
size of a macrophage
15-80 um
CD markers of T cells
CD2, CD4, CD8
CD markers of B cells
CD10, CD19, CD24
CD markers of null lymphocyte
CD16, CD56, CD94
appearance of plasmacytes
nucleus: cartwheel
cytoplasm: perinuclear hoff
WBC count in granulocytosis
> 10,000/mm3 (>11,000/mm3)
WBC count in granulocytopenia
<3,000/mm3
count in eosinophilia
> 400/mm3
count in basophilia
> 40/mm3
count in monocytosis
> 800/mm3
