6.MESOPOTAMIAN ( 3000 – 668 )
- The origins of civilization can be traced to a group of people living in southern Mesopotamia called the Sumerians. By 3500 BC, the Sumerians had developed many of the features that characterized subsequent civilizations. True civilization is said to have begun around 3100 BC with the development of cuneiform writing.
- Cuneiform was a system of writing established by the Sumerians which required the use of a stylus in order to make wedge-shaped marks on wet clay tablets, once the tablets were dry they could by stored, transported, etc. Many of the tablets that do mention medical practices have survived from the library of Asshurbanipal, the last great king of Assyria (668 BC)
- Mesopotamian diseases are often blamed on pre-existing spirits: gods, ghosts, etc.
- Each spirit was held responsible for disease in specific part of the body.
- It can also be shown that the plants used in treatment were generally used to treat the symptoms of the disease.
- Specific offerings were made to a particular god or ghost when it was considered to be a causative factor.
- There were two distinct types of professional medical practitioners in ancient Mesopotamia:
- The wealthiest patients probably sought medical attention from both an Ashipu and an Asu in order to cure an illness.
- Ashipu and the Asu often worked in cooperation with each other in order to treat certain ailments.
Law Code of Hammurabi :
- It was not a code of law in the modern sense, but probably a collection of legal decisions made by Hammurabi (1700 BC) in the course of his activities as a judge and published to advertise his justice.
- Several similar collections are known from other areas and periods, and Hammurabi’s cannot be taken as representative of all Mesopotamian justice — in fact, it is outstanding for its application of the principle of an eye for an eye and a tooth for a tooth, while other “codes” allow monetary penalties.
- If a surgeon operated and saved the life of a person of high status, the patient was to pay ten shekels of silver.
- If the surgeon saved the life of a slave, he only received two shekels.
- However, if a person of high status died as a result of surgery, the surgeon risked having his hand cut off. While if a slave died from receiving surgical treatment, the surgeon only had to pay to replace the slave.
Temple of Gula :
- Temple Gula was one of the alternative method for procuring health in Mesopotamia.
- Patients were not housed at the temple while they were treated.
- These temples may have been sites for the diagnosis of illness
- These temples were also libraries that held many useful medical texts.

- Age of scientific revolution
- 20th century philosopher Alfred whitehead mentions the 1600’s as the “century of genius” as Galileo, Newton, Kepler, Descartes, Bacon, & Harvey graced the century by their presence.
- Renaissance certainly prepared the way for modern science.
- The 17th cent made great advances that established the natural science by turning from speculations to experimentation.
- The 17th cent was also an age of religion.. During this cent different schools like materialism, idealism & substantial’s continued to speculate & interpret their observations in their own methods. Advancement in physical science provided materialism the upper hand.
- The two philosophers who profoundly influenced the seventeenth century and also had its effect on the medicine were F Bacon & Rene Descartes.
During the 17th cent different schools continued to speculate & interpret their own methods :
- Idealism: experience is ultimately based on mental activity.
- Materialism: holds that the only thing that exists is matter. That all things are composed of material and all phenomenon are the result of material interactions. So to many philosophers physical’s is synonymous with materialism. Advancement in physical science provided materialism an upper hand over the other schools
- Substantialism: matter does not disappear it only changes form..
FRANCIS BACON (1561-1626) :
- He played a major role in the rise of modern medicine. He emphasized the observation of phenomena & the accumulation of data. He privileged the process of induction over deduction.
- Bacon taught men to take “reason” directly from the pages of nature. He emphasized that truth is the daughter of time, not of authority.
- Acc to Bacon man using his art could do nothing but bringing things near to one another & the rest is performed by nature. Thus art can give only certain powers in a particular direction & medicine is the art by which such a particular direction is given to certain powers of nature to check diseases. All therapeutics are only giving certain powers of nature a particular direction.
- Bacon brought out the faults of Aristotelian system of syllogism (reasoning from general to particular i.e,deductive reasoning).
- He lead no new school of philosophy he simply revived the platonic method of reasoning in his book “NOVUM ORGANUM”
- His two important major writings are:
- Advancement of learning—1605
- NovumOrganum— 1620
- Father of modern philosophy
- Devoted his entire life to scholarship in the field of mathematics & philosophy.
- He invented analytical geometry.
- Acc to him all things in nature including animals were machines composed of substances in motion, governed by mechanistic principles obeying mathematical laws.
- He made a sharp distinction between the body & mind, stating them as radically different entities.
- He believed that intelligent soul was located in the pineal gland of the brain & that soul caused movement in the body by stirring up the brain thus generating animal spirits in the cerebral ventricles with the spread of these spirits to cause movement of blood.
WILLIAM HARVEY( 1578-1657)
- Born in folkestone , England.
- Description of little doors (the valves) by his teacher Fabricius was an important observation which Harvey latter used to support his circulation theory.
- Obtained his medical degree at the age of 24.
- While practising medicine he found out time to carry out investigations in anatomy & in physiology, dissecting more than a hundred different species of animals & humans.
- It was from these studies that his ideas emerged crystallizing his work “De MotuCordis et Sanquinis in Animabilus”(on the motion of the heart & blood in animals) published in 1628 which set out his revolutionary theory of the circulation of blood.
- Thomas Sydenham, MD : the father of clinical observation – 1624-1689
- He has been hailed as the “English Hippocrates”. He opposed iatro-physical and iatro-chemial view, instead suggested observation and recording of clinical phenomena.
- He preferred simple remedies.
- He advised specifics for diseases conditions & to observe and to follow nature. He went back to the Hippocratic method of recording the sick phenomenon . He put two alternative before medical profession
- To follow Hippocrates & imitate the methods of nature.
- To attack maladies directly with specifics.
- His opinion was that the art of healing would attain full maturity only when specific medicines for all the prevalent diseases are discovered. He could not live up to his ideals due to the shortage of such specifics.
ATHANASIUS KIRCHER (1602 – 1680) :
- He published a work in 1646 which included a chapter on the wonderful structure of things in nature, investigated by the microscope.
- He published physico-medical scrutiny of contagious pestilence in 1658.

- This was an encyclopaedia which contained a record of each recognizable disease from ancient times to that date.
ROBERT BOYLE (1627 – 1691) :
- He published his first book in 1660. this volume contained his law, “at a stated temperature a given mass varies inversely proportional to the pressure.”
- He studied respiration, combustion, the chemical nature of blood and urine, magnetism, electricity and almost every thing except astronomy.
- He was considerably influenced by Lord Bacon. He asked the physicians to dismiss prejudice and blind authority.
- He wanted the physicians to concentrate more on the “uncertainities’ of diseases than the ‘certainities” because he visualised diseases as phenomena and he believed that restoration of the sick and relief of sufferings depend on the uncertain aspects of diseases.
- He was against mixture prescription.
- He criticized the blind methods of Galen and also Hippocrates’ imitation of Nature, in their therapeutics.
- He asked the physicians to find out substances which exercise a directly curative power-a power of neutralising the causes of diseases, without producing any disturbing effects on the body.

–1928-Oskar winter Steiner proved insulin was a protein
–1955-FREDERICH SANGER found amino acid sequence of human insulin
3-ANTI TUBERCULAR DRUG
–HOWARD FLOREY, EARNST CHAIN, SEMAN A WAKSMAN discovered streptomycin-first effective anti tubercular drug-they got Nobel Prize in 1952
-Florey and chain showed that penicillin could be used to save lives
4-RESISTANCE TO ANTIBIOTICS
-antibacterial, antifungal, ant parasitic and, antiviral drugs had to face resistance
-for psychiatric complaints
– were introduced in 1903
-followed by phenobarbitone in 1912, and evipan-barbiturate anesthetic in 1932
-In 1910 EHRLICH and Dr.Harta (japan) discovered salvarsan –for syphilis

-Term coined by MARGERATE SANGER in1914
-contraceptives were criminalized that time
-1921-foundation of American birth control league
-she along with GREGORY and MC CHIANG found first oral contraceptive in 1960(envoid)
-Polish biochemist FUNK isolated first vitamin –riboflavin
-funk coined the term vitamin-vita=life. amine=a chemical term
