Transcript of Medical Breakthroughs in the 1920s

Rachel Fowler Medical Breakthroughs in the 1920's Medical Breakthroughs in the 1920's Thanks to the advances in medicine during the 1920's, people all over the world have access to penicillin, medical inventions, vitamins, and insulin that help to save lives everyday. Discovery of Penicillin In 1928, Alexander Fleming, by accident, discovered penicillin. He noticed substantial changes in a certain bacteria he was studying. The bacteria had dissolved, and a mold had appeared. Fleming had unintentionally left the bacteria uncovered. However the mold in the bacteria contained traces of penicillin. He then realized that the penicillin in the mold is what killed the bacteria. Medical Inventions During the 1920's, several inventions were brought about to better detect and treat injuries, tumors, and diseases. Discovery of Vitamins Discovery of Insulin The EEG The EEG or electroence-phalograph measures brain waves to detect tumors or injuries and was discovered by Hans Berger. Paps Smear George N. Papanicolaou invented the Papanicolaou Smear, also known as the Pap smear. This invention stained the cells of diseased tissue, which made it easier for physicians to directly locate and treat a specific part of the disease. The Iron Lung Phillip Drinker and Lewis Shaw invented the iron lung. The iron lung helped individuals who were unable to breath on their own. Christiaan Eijkman and Frederick Hopkins were the first to discover that the body needed certain nutrients to survive. They named these nutrients vitamins. Elmer McCullum later discovered vitamin D, and its ability to cure rickets a skeletal disease. Vitamin E was later introduced and proven to help problems with infertility and prevent skeletal abnormalities. In years previous to the twenties, diabetes was considered a fatal disease, and killed millions each year. In 1922, Frederick Banting has an idea for a possible treatment for diabetes. Banting created a pancreatic-extract, which is now known as insulin, and injected it into diabetic dogs. The dogs' health improved, and shortly after insulin was being produced and saving lives around the world. Timeline of Medical Advances in the 1920's Phenobarbital is used as a treatment for epilepsy (seizure condition). 1920 1925 Seale Harris discovers that diets should include decreased amounts of sugar because of its ability to cause excessive secretions of insulin. A husky named Balto leads a pack of sled dogs across Alaska with diphtheria (upper respiratory infection) medicine and saves many lives in Nome, Alaska. 1923 The first tetanus shots are administered to humans in France. 1927 Alexander Fleming reports his discovery of insulin. 1929 Manfred J. Sakel uses insulin shock as a treatment for schizophrenia. 1929 Works Cited Gutheil, William G. "Penicillin." Chemistry: Foundations and Applications. Ed. J. J. Lagowski. Vol. 3.
