Cooling or the application of mentholated liniments to the skin has been used to treat itch for centuries, yet remarkably little is known about how counter-stimuli such as these induce itch relief. Indeed, there is no clear consensus in the

Compound 48/80 inhibited phosphatidylinositol-specific phospholipase C activity from human platelets. Whereas 1 microgram/ml of compound 48/80 slightly stimulated Ca2+-dependent phospholipase A2, higher concentrations led to dose-dependent inhibition of this platelet enzyme. This biphasic effect was confirmed with phospholipases A2 purified
