Term
FLOW
Definition
Vasoconstriction followed by vasodilatation (Flooding)

Increase hydrostatic pressure (Load)

Slow circulation- viscosity, stasis (Onerous)

Permeability (Weeping)
Term
signs of inflammation
Definition
Rubor = redness
Tumor = swelling
Calor = heat
Dolor = pain
(described by Celsus 1st. Century AD)

Functio laesa = loss of function
(added by R. Virchow)
Term
FLAMM
Definition
Flowing
Leukoycte recruitment
adhesion
migraiton
mopping up
Term
stages of adehesion
Definition
rolling. integrina ctivation by chemokines. (E selectin and P selectin), stabel adhesion migration through endothelium.
Term
migration
Definition
Passive Through endothelial gaps Diapedesis

Active PECAM Degradation of BM and ECM

6-24 hrs Polymorphs
24-48hrs Monocytes, lymphocytes
Term
type of cell for acute
type of cell for chronic
Definition
Acute inflammation = neutorphil
Chronic inflammation = lymph
Term
chemotaxis agents used for leuokcyte migration
Definition
Chemoattractants
Exogenous - Bacterial products
Endogenous - C5a, LTB4, IL-8
Term
Mopping up part of FLAMM
Definition
Opsonization

Phagocytosis

Ping!
Oxygen dependent (free radicals)
Oxygen independent (enzymes
Term
important mediators in response
Definition
Inflamation: il 1, and TNF alpha impt for
IL2 and IFN = impt in immunology(t/ cell and b cell shelping each other.)
IL12: impt for thelp
IL4, 5, as helper T ell type 2.
KNOW THIS!
Term
reason of severe left shift in immune reponse--> granulocytosis
Definition
Leukocyte release results from a direct effect of IL-1 and IL-6 on bone marrow neutrophil stores.
Exaggeration of this can result in a “Leukemoid reaction” release of very immature precursors and cel
Term
serous
Definition
fluid w/ out pus
Term
catarrahal
Definition
blowing nose
Term
Morphologic Patterns
Definition
Serous
Catarrhal
Fibrinous
Hemorrhagic
Suppurative
Gangrenous
Pseudomembranous
Term
fibrinous
Definition
vascular permeability, larger molecules such as fibrinogen pass the vascular barrier, and fibrin is formed and deposited in the extracellular spac
Term
purulent/suppurative
Definition
production of large amounts of pus or purulent exudate consisting of neutrophils, necrotic cells, and edema fluid.
Term
ulcerative
Definition
Loss or destruction of epithelial.
Term
hemorrhagic
Definition
. Significant destruction of vesel walls. Sever vascularities can have hemmoragin manifestion w/ inflammation fo veslle wall
Term
gangrenous
Definition
more necrosis than inflammation
Term
termination of inflammation
Definition
Eradication of an offending agent
Neutrophils have only a short life span (few hours -1 day)
Most mediators are very short lived
Anti-inflammatory cytokines (TGF-beta, and IL-10) can inhibit the production of pro-inflammatory cytokines (TNF)
Arachidonic acid metabolites - lipoxin and resolvins - have anti-inflammatory activity

Exact mechanism elusive
Term
chronic inflammation
Definition
The proliferation of blood vessels, granulomas, tissue fibrosis and tissue necrosis.
Lymphocytes and macrophages.
Term
acute vs chronic
Definition
short vs long
neturophils /macrophages (acute)
lymphocytes, plasma cells, macrophages, fibroblasts (chronic)

very little changes in perphipheral blood in chronic. neutrophils presnt in acute.
Term
what does granuloma form around?
Definition
non degradable antigen
Term
caseous center
Definition
necrotziign granuloma
Term
actue polynephritis
Definition
inflition of neutorphils intratubula aggregate s of enturophils tubular necorsis. itssue look dusty lue pink
Term
temporal arteritis
Definition
presented with increasing headache and throbbing temporal pain. Associated symptoms include fever, and generalized muscle aching.


want to give steroid immediately. arteries are narrowed by intimal fibrosis


2/3 cases get giant cell
Term
Granulomas
Definition
grade fever, weight loss, and night sweats

Granulomas
Caseating necrosis: b/c of lots of
Mycloic acid.
Term
peptic ulcer
Definition
complains frequently of burning, gnawing, epigastric pain about 1-3 hours after his "two martini" lunches. Sometimes the pain awakens him at night.
Term
ulcerative colitis
Definition
intermittent attacks of chronic diarrhea and rectal bleeding that persists for days to sometimes weeks. These episodes have been recurrent over several years.


effects mucosa and submucos


Acute cryptitis
Cryptal abscess
Inflammation
Crypt architecture distortion
