1
Q
Histamine
A
Mast Cells, basophils, platelets
- vasodilation
- increased vascular permeability
- endothelial activation
2
Q

A
Mast cells, leukocytes
- vasodialtion
- pain
- fever
3
Q
Leukotrienes
A
Mast cells, leukocytes
- Increased vascular permeability
- chemotaxis
- leukocyte adhesion and activation
4
Q
