Fluid Of Inflammation

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