Слайд 3: HISTORY
The discovery of penicillin is due to the Scottish biochemist Alexander Fleming. During the First World War, Fleming served as a military doctor and could not accept the fact that the wounded after a successful operation still died - from the onset of gangrene or sepsis. In 1928, Alexander Fleming conducted an ordinary experiment in the course of many years of research devoted to the study of the struggle of the human body with bacterial infections.
Слайд 4: Work on the creation of Soviet penicillin began in the first year of the war at the All-Union Institute of Experimental Medicine. The head of the institute was Professor Zinaida Yermolyeva. In 1942, just a year after the English scientist Howard Flory managed to synthesize the first servings of penicillin, Ermolieva managed to achieve similar results using domestic raw materials. Penicillin Ermolieva saved the lives of thousands of wounded who were considered hopeless, however, his discovery did not have decisive importance in organizing medical assistance to Soviet soldiers during the war, since the first Soviet antibiotic was produced in those years in small quantities
Слайд 5: Chemical structure of penicillin
Penicillins ( penicillina ) - a group of antibiotics produced by many species of Penicillium molds, active against most gram-positive, as well as some gram-negative microorganisms (gonococci, meningococci and spirochetes). Penicillins belong to the so-called beta- lactam antibiotics (beta- lactams ). C16H18N2O4S C16H18N2O4S
Слайд 6: The value of penicillin in medicine
Today, its modifications are universally used to treat serious diseases and infections, which earlier, most likely, would lead to imminent death.
Последний слайд презентации: Ministry of science and higher education of the Russian Federation Medical: 4 Facts about the world's first antibiotic
1. Alexander Fleming, working in his laboratory, accidentally drew attention to a strange green mold that covered the bottom of one of the Petri dishes with bacterial inoculation. The mysterious mold seemed to dissolve them. Fleming thought that some extraneous dispute flew into the laboratory window and got into the dishes with the culture. The scientist called the product released by mold found in a cup with bacteria, "penicillin." 2. As a result of the studies, Fleming was able to find out that penicillin is capable of killing microbes causing: diphtheria, pneumonia, furunculosis, tonsillitis and others. The first cure for penicillin in humans was sinusitis, which suffered one of Fleming's assistants, Stuart Cradock. 3. Breakthrough medicine was not recognized immediately. Fleming announced his discovery to Sir Elmrot Wright, head of the microbiology department of the hospital in which Fleming's laboratory was located. 4. In 1944, Aleksander Fleming was granted the noble title, and in 1945 Fleming, Flory, and Cheyne became winners of the Nobel Prize.
