Fluid Of Inflammation
- 1) Suppurative/ Purulent
- Neutrophils dominate (dead and alive)
- Dead host cells
- Often bacterial in origin
- May become walled off by granulation or fibrous tissue
- Abscess
- Localized area of Liquefactive necrosis
- Empyema
- Accumulation of pus in a body cavity
- (Particularly within the pleural cavity)
- Pyothorax
- 2) Fibrinous
- Forms as a result of increased vascular permeability
- (fibrinogen escapes)
- Thrombin (acts on fibrinogen)
- fibrin
- Yellow, soft coagulum (on top of tissues)
- Thin Eosinophilic meshwork
- Acute (Vs. Fibrosis (chronic))
- 3) Serous
- Fluid + albumen + plasma proteins (protein rich, low cells)
- Early event
- E.g. Blisters, serous arthritis, peritonitis
- 4) Mucous/ Catharral
- When mucous hypersecretion accompanies inflammation
- Often in respiratory and GI tracts (where mucous secreting cells prominent)
- Ex. Nasal discharge
