Humankind’s attempt to treat & cure diseases can be dated back almost 5000 years to Egypt & Mesopotamia. Prehistoric skulls found in Europe & South America also demonstrate that early humans deliberately removed bone from the skull successfully. Whether this action was performed as a surgical treatment or as a religious attempt to release evil spirits is unknown. Many potent drugs still in use today, such as castor oil and opium, were used in ancient Egypt for medicinal purposes.  COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc. *Castor oil – (laxative) a drug used to stimulate or increase the frequency of bowel evacuation, or to encourage a softer or bulkier stool. *Opium- an extract from the poppy Papaver somniferum, which has analgesic & narcotic action due to its content of morphine. It has the same uses & side effects as morphine & prolonged use may lead to dependence. Despite their sophisticated embalming skills, the Egyptians demonstrated little knowledge of anatomy COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc.

Hippocrates (c. 460-370 BC) was a Greek Physician who is considered the father of Western Medicine. A contemporary of Socrates & was one of the most famous physicians & teachers of medicine of his time is generally accepted.  COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc. Hippocratic Corpus - more than 60 medical treatises - most of them was not written by himself. - The writings are similar in that they emphasize rational & natural explanations for the treatment of disease & reject sorcery & magic.  COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc. He emphasized the importance of careful observation of patient. He believed in the powers of nature to heal over time & taught the prevention of disease through a regimen of diet & exercise. He also attributed with developing a high standard of ethical conduct, as incorporated in the Hippocratic oath, which provided guidelines for physician-patient relationships, for the rights of patient privacy, & for the use of treatment for curative purposes only. Hippocratic Oath – it is still govern the ethical conduct of physicians today. Medicine was strongly controlled by religious groups during this period, and it was not until the early 1500s that a physician in England had to be licensed to practice.  COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc. The Romans recognized the importance of proper sanitation for good public health through their construction of aqueducts, baths, sewers and hospitals. Unfortunately, during the Middle Ages, the destruction or neglect of the Roman sanitary facilities resulted in many local epidemics that eventually led to the great plague, known as the “Black Death” during the 14th century. COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc.  COLLEGE OF RADIOLOGIC TECHNOLOGY Calayan Educational Foundation, Inc. CHRISTIANITY Christians sought to bring the healing message of Christ to those in need. Dark Ages, practices involved prayer, exorcism, holy oil, relics of saints, supernaturalism, and superstition.
