WBC Flashcards
Is the orderly production of mature granulocytes (N,E,B)
GRANULOCYTE PRODUCTION
days of maturation sequence
about 14 days
normal range of wbc in full term infant
10,000-25,000/uL of blood
normal range of wbc in infants up to 1 yr of age
6,000-16,000/uL of blood
normal range of wbc in adults
4,000-11,000/uL of blood
detection of changes in. numbers of circulating WBCs
differential wbc count
what does differential wbc count indicates
indicates infection, poisoning, leukemia, chemotherapy, parasites or allergy reaction
normal wbc counts
N = 60-70%
L = 20-25%
M = 3-8%
E = 2-4%
B = <1%
wbc counts is up if..
N = bacterial infection
L = viral infection
M = fungal/viral infection
E = parasitic or allergy reaction
B = allergy or hypothyroid
normal values of WBC count
5,000-10,000/cu mm or 5-10 x 10^9/L
differential count normal valaues
N = 50-70% (segmenter 50-65% ; stab 0-5%)
L = 20-40%
M = 2-6%
E = 0-3%
B = 0-1%

Myeloblast-
first appearance of primary granules
promyelocyte
first appearnce of secondary granules
Myelocyte
youngest stage
metamyelocyte/juvenile
Youngest cell to appear in peripheral blood
Band/stab/staff
mature granulocytes
Neutrphil, Eosinophil, Basophil
secondary or specific granules in neutrophil
Aminopeptidase, collagenase, muramidase, lactoferrin, lysozyme, basic proteins, plasminogen activator, Alkaline phosphatase
Larger granules;major basic proteins in Eosinophil
Acid hydrolase, peroxidase, phospholipase, cathepsin, Eosinophilic, Cationic CHON, Eosinophil-derived neurotoxin.
Smaller Granules in eosinophil
Arylsulfatase, Peroxidase, Acid phosphatase
secondary or specific granules in basophil
Histamine, Heparin, Peroxidase, Eosinophilic Chemotactic Factor A
Granules: pink-rose violet granules
neutrophil/pmn
Mature neutrophil, ratio of primary to secondary granules is
2-3:1
____ together with ____ and ___ kills bacteria
Myeloperoxidase (MPO) together with Hydrogen peroxide and halide kills bacteria
Present in primary and 2ndary granules degrades glycopeptides & hydrolyzes carbohydrates of the bacterial cell wall
Lyzozyme or Muramidase
