|
Name the most likely reason why/where you would see the following in a cytological /histological slide.
Neutropils |
-Acute infection
-Foreign Body |
|
|
Eosinophils
|
-Inflammatory reaction
-Immunological disease -Allergic reaction -Parasite reaction |
|
|
Lymphocytes
|
-Inflammatory reaction - subacute and chronic (after neutrophils)
(Purple stained cells dominated by nucleus) |
|
|
Plasma Cells
|
-Sites of constant antigenic challenge (GI tract & URT)
-Often with lymphocytes (Cells with expanded cytoplasm and halo next to nucleus - golgi complex secreting Ab) |
|
|
Macrophages
|
-Inflammation (termed Granulomatous)
Fxn: Phagocytosis |
|
|
Mast Cells
|
-Inflammation (source of vasoactive amines)
(Special Stain-Toluidine Blue picks up metachromatic granules in cells) |
|
|
Fibroblasts
|
-Healing
-Repair (Synthesize and lay down collagen) |
|
|
Hemosiderophage
|
Macrophage that has phagocytised a RBC.
*Indicative of heammorrhage |
|
|
Pyogranulomatous
|
Mixed puss (neutrophils) and macrophages
|
|
|
Giant Cells
|
Multinucleated macrophages
|
|
|
Supperative/Purulent
|
Dead or live neutrophils and dead host cells. Often bacterial in origin.
(Ex: Abscess) |
|
|
Fibrinous
|
Thin eosinophilic meshwork (yellow, soft coagulum). Seen in some inflammatory reactions.
*Increased vascular permeability leads to escape of plasma proteins containing fibrinogen, which forms fibrin. |
|
|
Serous
|
Fluid, albumen and other plasma proteins that leak out during the early part of inflammation.
Ex: blisters, synovitis, serous rhinitis. |
|
|
Mucous/Catarrhal
|
Hypersecretion of mucous secreting cells in respiratory and GI tract.
|
|
|
Empyema
|
Puss filled hallow visera or pleural cavity.
|
|
|
Define Morhphological Change.
|
Structural changes in cells or tissues in association with disease.
|
|
|
Define Pathogensis.
|
Sequence of event following exposure to an inciting agent or event.
Stimulus-->Expression |
