a chemoattractant for neutrophils.
LTB4
are potent bronchoconstrictors and
cause increased microvascular permeability, plasma

EETs
Block all the known pathways of eicosanoid synthesis,
CORTICOSTEROIDS
Block all the known pathways of eicosanoid synthesis, partly by
stimulating the synthesis of several inhibitory proteins collectively
called
annexins or lipocortins.
CORTICOSTEROIDS They inhibit (blank) activity, probably by interfering with
phospholipid binding, thus preventing the release of arachidonic

phospholipase A 2
Block both prostaglandin and thromboxane formation by
reversibly inhibiting COX activity.
NSAIDS
are not selective for COX-1 or COX-2.
