Inflammation Flashcards
Characteristics of a Neutrophil
Mature: 3 multilobed nucleus
Immature: not folded nucleus
Characteristics of Eosinophils
Bilobed nucleus
Lare, Red cytoplasmic granules
Characteristics of Basophils
Nucleus obscured by dark blue granules
Characteristics of Lymphocytes
Single lobed, usually round
Characteristics of plasma cells
“Clock face: nucleus and perinuclear hof (Pink area)
Characteristics of Monocytes
Bean shaped, mononuclear
What are the cardinal clinical signs of acute inflammation?
Warmth
Redness
Swelling
Pain
Loss of function.
What are the systemic findings of acute inflammation
Chills
Fever
Myalgias
Acute inflammation lab findings: CBC
Increased WBC
Neutrophilia (sometimes with left shift)
Viral infection: lymphocytes
Parasitic: Eosinophilia
Acute inflammation lab findings: Finbrinogen, C-reactive protein
Increased levels.
These are acute phase proteins
Acute inflammation lab findings: Erythrocyte Sedimentation Rate (ESR)
Increased level
an indirect measure of fibrinogen
Mediator actions: Cytokines
Amplification and regulation of inflammation, fever
synthesis is required (macrophages, others)
Mediator actions: Histamine
Increased vascular permeability, vasodilation
Preformed in mast cells and platelets
Mediator actions: Leukotrienes
Chemotaxis, increased vascular permeability
Synthesis required (WBCs)
Mediator actions: Prostaglandins
Fever, pain, vasodilation
Synthesis required (WBCs)
What type of mediator is cytokins?
proteins
What type of mediator is Histamine?
Amine
What type of mediator is Leuotrienes?
Fatty acid Derivatives
What type of mediator is prostaglandins?
fatty acid derivatives
Corticosteriods inhibit what in inflammation?
Phospholipase
NSAIDs inhibit what for inflammation?
Cyclooxygenase
Wheal (edema) and flare (erythema) acute inflammation
allergen -> allergen - IgE - mast cell -> degranulation - > histamine - > vasodilation
Serous acute inflammation
injury -> leakage of cell and protein poor fluid
*Blister
Fibrous inflammation
Exudate: Proteinaceous fluid in extravascular space
Example: Fibrinous pericarditis (bread and butter)
Suppurative inflammation
Abscess - collection of neutrophils
Bacterial infection -> acute inflammation
Example: boil (furuncle)
Catarrhal Inflammation
Abscess mucous membrane
Ex: rhinorrhea
