A lobotomy (from Greek λοβός (lobos) 'lobe', and τομή (tomē) 'cut, slice') or leucotomy is a discredited form of neurosurgical treatment for psychiatric disorder or neurological disorder (e.g. epilepsy, depression) that involves severing connections in the brain's prefrontal cortex.[2] The surgery causes most of the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain, to be severed.

Xenotransplantation (pronounced zee-no-tran-splan-TAY-shin) is when non-human cells, tissues, or organs are used to treat medical conditions in humans. More people need organs than what is available. On average, seventeen people die each day in the United States waiting for an organ transplant. Finding other sources for organs is critical to save lives.

Bloodletting (or blood-letting) is the withdrawal of blood from a patient to prevent or cure illness and disease. Bloodletting, whether by a physician or by leeches, was based on an ancient system of medicine in which blood and other bodily fluids were regarded as "humours" that had to remain in proper balance to maintain health. It is claimed to have been the most common medical practice performed by surgeons from antiquity until the late 19th century, a span of over 2,000 years.[1] In Europe, the practice remained relatively common until the end of the 19th century.[2] The practice has now been abandoned by modern-style medicine for all except a few very specific medical conditions. In the overwhelming majority of cases, the historical use of bloodletting was harmful to patients.
