Inhibition of cytokine secretion from human leukemic mast cells and basophils by H1- and H2-receptor antagonists.

Mast cells are what cause reactions when you get stung by a bee for example.

Trust me... I know, I am severely allergic to them.

Take it or leave it, but it might just save your life.
