1. Anaphylatoxins
The C3a and C5a fractions during complement fixation. They act to mimic some of the reactions of anaphylaxis and can induce the release of histamine from mast cell s. C5a is also chemotactic for neutrophil s and monocyte s.

2. Granulocytes (polymorphonuclear leukocytes)
A class of leukocyte s characterized by the presence of granules in their cytoplasm . These cells are active in allergic immune reactions such as arthritic inflammation and rashes. All granulocytes contain the enzyme myeloperoxidase . This class includes basophil s, eosinophil s and neutrophil s; they are classified according to the pattern/color they exhibit when they are stained with certain dyes.

3. LE cell prep
This is a test to diagnose systemic lupus erythematosis (SLE). Nuclear material from lysed WBC is incubated with the patient's serum and neutrophils. If antibodies against nuclear material is present, neutrophils would phagocytize the antibody bound complex. A positive result is one in which neutrophils with a homogenous red-purple inclusion that distends the cell's cytoplasm is found. Of patients with active SLE, 70 to 80% will have positive LE prep.

4. Neutrophil
A large, granular leukocyte that will stain with neutral dyes and eosin and which has a multi-lobed, irregular nucleus .

5. Phagocytes
White blood cells that can engulf (by phagocytosis) and destroy microorganisms including viruses and bacteria; cells in this category include neutrophils and monocytes.

6. SRS-A (slow-reacting substance of anaphylaxis)
This is a mixture of molecules called leukotrienes which are formed by the mast cells, from the metabolism of arachidonic acid . SRS-A is a potent chemotactic agent affecting neutrophil s, eosinophil s, and monocyte s.
