quantitative = MACRO changes = change in cell ____ both __ and __
Number - absolute - relative %
26
Qualitative = MICRO changes = change in cell ___ both __ and __
Morphology - nucleus - cytoplasm
27
Penia & Philia think:
quantitative
28
Congenital and Acquired think:
Fxn Disorders = qualitative
29
WBC disorder pathophysiology effects (3)
- demargination (double #) - Release early from BM (left shfit) - Increased production (neutrophilia)
30
what causes WBC pathophysiology
- stress (pseudoneutrophilia) - acute inflammation - chronic infection
31
If you see Left Shift Think:
Acute inflammation
32
Neutrophilia defining features
- left shift | - Toxic Granules (dohle, vacuoles, intra-cellular microbes)
33
Rough endoplasmic reticulum containing RNA = ? | ***represent localized failure of maturation
Dohle bodies
34
Dohle bodies found in what situations?
``` infection (bacteria/parasite) poisoning burns chemotherapy neoplastic disease myeloproliferative Ds preggo ```
35
physical stimuli -> neutrophilia
cold/heat/exercise, pain, period, ovulate, labor/preggo, trauma/gout/infarcts, nausea, vomit, smoking
36
emotional stimuli -> neutrophilia
fear/panic elation/joy/excited anger/depressed/anxious
37
Rx -> neutrophilia
epinephrine steroids lithium (depression) venom/poison/toxin
38
metabolic -> neutrophilia
ketoacidosis uremia eclampsia (preg HTN) thyrotoxicosis
39
which race = neutropenia?
african & middle eastern
40
Rx -> neutropenia

BM failure (anemia types)-> neutropenia
megaloblastic and aplastic anemia
44
Neutropenia pathophysiology = decreased what?
- proliferation (aplasia) - maturation (precursor prob) - survival (destruction/removal too fast) - distribution (normal stores, can't transport)
