Aaron's Rod: (Used as a symbol for medicine.) A rod (walking stick) with one serpent twined around it, thus differing from Mercury's Caduceus (also used as a symbol of medicine), which has two serpents twined about it. The allusion is to the rod God gave to Moses and his brother Aaron with which to perform miracles and free the Israelites from bondage in Egypt. In the first miracle the rod changed into a serpent in front of Pharaoh. (Unfortunately Pharaoh didn't give a rip.)
Abacterial Thrombotic Endocarditis: Lesions inside the heart occurring with blood clots and inflammation of the wall of the heart in the terminal stages of many chronic infectious and wasting diseases. Synonyms are nonbacterial thrombotic endocarditis, cachectic endocarditis, terminal endocarditis, and thromboendocarditis.
