|
Arachidionic Acid ----(5-LO)--->Leukotrienes
|
|
Activated Hageman Factors
|
XII a (Coagulation Pathway)
-->intrinsic coagulation -->prekalikrien activation --> plasminogen activation (degrade fibrin clot) |
|
Thrombin Activity
|
-fibrinogen cleavage

Vasodilation
Potentiates edema |
|
NSAID MOA
|
blocks COX
blocks formation of prostaglandins shifts over to leukotrienes DO NOT GIVE TO ASTHAMATICS |
|
Zyflo MOA
|
blocks 5-lipooxygenase
blocks formation of leukotrienes good for asthamtics |
|
Corticosteroids MOA
|
blocks activity of PLA2
cannot form ARACHIDIONIC ACID cannot make PGAs and leukotrienes decrease inflammation |
|
Platelet Activating Factor
(activity) |
Vasoactive (erythema, edema)
Chemotaxis Platelet activation Leukocyte stimulation Endothelial cell activation Cell adhesion molecule Pain |
|
NO made by
|
-endothelial cells
(stimulated by bradykinin) -NO will increase cGMP |
|
IKB
|
inhibitor of kappa-beta
inhibits TF NF-KB corticosteroids will increase IKB |
|
CAMS
|
endothelial cells bind to adhesins on WBC
|
|
Where WBC margination, rolling, stopping, and diapedesis occurs:
|
ARTERIOLES: rolling and adherance
CAPILLARIES: stopping VENULES: diapedesis |
|
PECAM-1
|
modulates endothelial migration of leukocytes
|

|
sensitizes specialized nerve endings to the effects of bradykinin
|
|
Bradykinin
|
-vasodilation
