Imhotep diagnosed and treated over 200 diseases, 15 diseases of the abdomen, 11 of the bladder, 10 of the rectum, 29 of the eyes, and 18 of the skin, hair, nails and tongue. Imhotep treated tuberculosis, gallstones, appendicitis, gout and arthritis. He also ‏لو كر‎ surgery and practiced some dentistry. Imhotep extracted medicine from plants. He also knew the position and function of the vital organs and circulation of the blood system.

His prestige increased with the lapse of centuries and his temples in Greek times were the centers of medical teachings."

77B.C. © Hippocrates is know as the “Father of Medicine.” He is considered one of the greatest physicians the world has ever known. © He was the first to attempt to separate the practice of medicine from religion and superstition. © Hippocrates developed his pledge of proper conduct for doctors. “I will use treatment to help the sick according to my ability and judgment, but never with the view to injury and wrong doing...Into whatsoever houses I enter, I will enter to help the sick.”

And in particular, as the season and the year advances, he can tell what epidemic diseases will attack the city, either in summer or in winter, and what each individual will be in danger of experiencing from the change of regimen.

The Hippocratic Oath © Hippocrates also made changes in how physicians looked upon their profession. © During his time, a doctor was sometimes bribed to see that a patient died, or asked to prepare poison to kill an enemy. If a ruler wanted to rid himself of a rival, he could hire a court physician who would see that the rival became sick and died. © Hippocrates taught against such improper conduct. He told his students to treat everyone the same. © “Sometimes give your services for nothing...for where there is love of man, there is also love of medicine.”

‘Windows to the Body” © Galen, the great 2>¢ century physician and anatomist, spent his early medical career as a surgeon to the gladiators. © He employed as many as 20 scribes to write down all that he said in the work. © He dissected countless animals in his prolific medical research. ® Galen also studied philosophy and wrote that a motive of profit was incompatible with a serious devotion to medicine, stating that doctors must learn to despise money. © He was a proponent of the miasma theory of infection, which essentially blamed infection on clouds of poisonous gases.

or ser Infallible Master” © The profession of medicine gained a wealth of facts and ideas from Galen. © He gave to the world a synthesis of medical thought and knowledge solid enough to last nearly 1500 years. © His mind was quick and well organized. © He was well informed on many subjects. ® In the earlier period of his life, he continually insisted on experiments and on demonstrable proofs. © But the open-minded young Galen later became one of the great dogmatists of all times. The magnitude of his dogmatism was increased by his followers and commentators. 

صفحه 38:
Galen ® Galen believed that disease resulted from an imbalance of the vital fluids, or humors, of the body. This idea was developed by Hippocrates, and consolidated by Galen. © “The body has in itself blood, phlegm, yellow bile, and black bile...We enjoy the most perfect health when these elements are in the right proportion.” © The medicine and pathology Galen practiced, and about which he wrote, were based mainly on speculative Hippocratic theories of the 4 humors, on critical days, and on fallacious theories regarding pulse and urine.

The Four Humours ® Developed out of the humoral theory of Empedocles(500 to 430B.C.), the Scilian philosopher. © Developed by Hippocrates and consolidated by Galen. © From the 4 elements: earth, air, fire and water derived the idea of the 4 humours(or fluids) of black bile, yellow bile, blood and phlegm with their associated meancholic, choleric, sanguine and phlegmatic temperments. © It was believed that the balance of these humours in the body determined physical states of health.

The Father of Modern Surgery © Professors in medical schools seldom performed surgery. © They did not think that it was proper for a professional man to do such work. ® Surgeon is from a French word meaning “one who works with his hands.” © In the Europe of the 1500s, barbers, not doctors, performed minor operations, pulled teeth, and treated cuts. © Barbers who gained skill in closing wounds were called barber-surgeons.

© The barber pole is a symbol of the profession and is a legacy of bloodletting. © After the operation, the bandages would be hung on the staff and sometimes placed outside as advertisement. © Twirled by wind, they would form a red & white spiral pattern that was later adopted for painted poles. © The earliest poles were surmounted by a leech basin, which in time was transformed into a ball. © The stripes of a barber pole still show the red for blood and the white for bandages. Sometimes there were poles with blue representing the veins.
