Answer to Question 1

ANS: B
Prostaglandins cause increased vascular permeability, neutrophil chemotaxis, and pain by direct effects on nerves. Histamine promotes vasodilation. Prostaglandins are not associated with vas-oconstriction or the immune complex formation.

Answer to Question 2

ANS: C
Aspirin is a prostaglandin inhibitor. Aspirin is not associated with leukotriene production, hista-mine release, or platelet-activating factor.
