| BACTERIOLOGY Al-Razi was asked to choose a site for a new hospital when he came to Baghdad. First he deduced which was the most hygienic area by observing where the fresh pieces of meat he had hung in various parts of the city decomposed least quickly.
Ibn Sina stated explicitly that the bodily secretion is contaminated by foul foreign earthly body before getting the infection. Ibn Khatima stated that man is surrounded by minute bodies which enter the human system and cause disease.
In the middle of the fourteenth century "black death" was ravaging Europe and before which Christians stood helpless, considering it an act of God.
At that time Ibn al Khatib of Granada composed a treatise in the defense of the theory of infection in the following way: To those who say, "How can we admit the possibility of infection while the religious law denies it?" We reply that the existence of contagion is established by experience, investigation, the evidence of the senses and trustworthy reports. These facts constitute a sound argument. The fact of infection becomes clear to the investigator who notices how he who establishes contact with the afflicted gets the disease, whereas he who is not in contact remains safe, and how transmission is effected through garments, vessels and earrings.
Al-Razi wrote the first medical description of smallpox and measles - two important infectious diseases. He described the clinical difference between the two diseases so vividly that nothing since has been added. Ibn Sina suggested the communicable nature of tuberculosis. He is said to have been the first to describe the preparation and properties of sulphuric acid and alcohol. His recommendation of wine as the best dressing for wounds was very popular in medieval practice. However Razi was the first to use silk sutures and alcohol for hemostatis. He was the first to use alcohol as an antiseptic. | |
