Who Invented Insulin?

Who Invented Insulin?

The history of insulin as medical treatment started around 1921-22. Dr. Frederick Banting of Toronto University discovered in his research that the hormone could be used to treat diabetes. Other researchers who helped him were Charles Best and Dr. James Collip. Early Research on Insulin It was a Berlin student named Paul Langerhans who discovered insulin in the pancreas in 1869. Langerhans called it insulin which in German means islet or island, for that is what the hormones look like. Initially it was thought that insulin played a role in digesting food. In 1889, a Polish-German scientist named Oscar Minkowski began studying the pancreas of the dog. When he took out the dog’s pancreas, he noticed flies kept going to the animal’s urine. This would be pivotal in the history of insulin as the scientists learned there was sugar in the urine. They established the link between pancreas, sugar and diabetes. In 1901 Eugene Opie discovered that diabetes and insulin (or islets) were closely linked, and not just pancreas and diabetes. Further Studies on Insulin This discovery convinced scientists that insulin could be used to produce treatment for diabetes. Some of the early researchers who tried extracting it were George Zuelzer in 1906 and E.L. Scott of Chicago University in 1912. However the outbreak of World War I interrupted research on insulin and diabetes. In 1921 a professor in Bucharest named Nicolae Paulescu became the first in the history of insulin to isolate it. While he patented his work, no clinical tests took place. Banting’s Work Banting’s work however, was the first that resulted in clinical testing. It took place in January 11, 1922. A 14 year old diabetic patient in Toronto was given an insulin injection. The injections...
Who Invented the Hearing Aid?

Who Invented the Hearing Aid?...

No one really knows who invented the first hearing aid device. A study of the history of hearing aids will show that one of the first electric hearing aids was the Akoulathon. This was made by Miller Reese Hutchinson in 1898. Hutchinson’s Invention Hutchinson’s creation was sold in 1901 by the Akaphone Company. The apparatus itself required a carbon transmitter for the hearing aid and telephone. The device was subsequently used to increase the sound. By the 1920’s the transistor took the place of the carbon transmitter. Early History of the Hearing Aid However there were other forms of hearing aid that came out before Hutchinson’s invention. These consisted of trumpets, horns and other similar designs. These devices would later change into transistor radio like devices. During the early history of hearing aids, these devices had to be worn around the body. They were quite heavy and uncomfortable to wear. These early devices were called ear horns or trumpets. They were shaped like funnel cones and worked by concentrating sound into the funnel. These prototypes were later replaced by the bone anchor hearing aid. Different Types of Hearing Aids Since Hutchinson’s invention, hearing aids have assumed various forms and shapes. One of the earliest types was the body worn aid. This was invented by Bells Labs researcher Harvey Fletcher. In the long history of hearing aids, Fletcher is in fact often credited with inventing hearing aids. Fletcher’s invention consisted of an ear mold and a case where the amplifiers were stored. The case and ear mold were linked by a cord. These would soon be replaced by the BTE (behind the ear) aids. These consisted of plastic and set on the pinna. Using air conduction, sound is sent to...
Who Invented Physical Fitness?

Who Invented Physical Fitness?...

Who Invented Physical Fitness? Physical fitness as a special discipline was unknown in times past. Men and women had to go out and get things just about all the time. So there was no need to invent activities just to stay fit. Primitive people (10,000 BC and earlier) for example, were always out hunting or gathering food, chasing (or running away from) wild animals, or moving to new territory. Things changed somewhat at around 8,000 BC when men first learned how to raise crops and keep farm animals. But their lives were still very active on the whole. It was only much later when human life became very sedentary that the concept of physical fitness began to arise. At some point in time, people began to associate certain diseases with wrong or lack of physical exercise. It is here we can say that physical fitness has its first incarnation as a separate discipline. The oldest traces of references to physical fitness go back to around 2,500 BC in different regions. Foremost of these was Greece. It was the Greeks who invented both the Olympics and the gymnasiums. The Athenians idealized the human body and physical fitness so much that they held sports events regularly to celebrate it. Physical strength played an even bigger role in Sparta, but it was more for military purposes than anything else. In China, the government and society were strongly influenced by Confucius’ ideas. Confucianism encouraged physical fitness for health as well as ethical reasons. The Chinese Taoists also had reasons to invent physical fitness: they wanted to extend life if not become immortal. So the Chinese developed exercise routines known as Kung Fu, Tai Chi, Chi Kung and other names. A similar development happened...
Who Invented the Electronic Cigarette?

Who Invented the Electronic Cigarette?...

Since around the later portion of the 1950s, society started to realize that tobacco cigarettes caused health problems. As research progressed along with increasing numbers of people that developed lung cancer, emphysema, and other smoking related illnesses, cigarette smoking has become less accepted and popular. Unfortunately, the nicotine contained in cigarettes is one of the most addictive substances on the planet and makes quitting smoking one of the hardest things to do. In 2003, Chinese pharmacist, Hon Lik invented the electronic cigarette as a safer, and cleaner way to inhale nicotine after his father, a heavy smoker, passed away from lung cancer attributed to smoking tobacco cigarettes. The Invention of the Electronic Cigarette Hon Lik applied for his first patent on the electronic cigarette in 2003 and subsequently introduced e cigs to the Chinese Market in the following year through his employer, Golden Dragon Holdings. Golden Dragon Holdings later changed the company name to “Ruyan” in order to better match the company’s name (Ruyan means “almost like smoke”) to the new product. Since the renaming, the Ruyan company has continued e cigarette development and grown to be one of the largest global e cig manufacturers. Dr. Sam Han, CEO of Cixi E-CIG Technology, Inc. Ltd. Is also attributed with a number of e cig related inventions to include four patents in the United States and two in China that are electronic cigarette and e-liquid technology related. Similar to Hon Lik, Dr Han was a heavy smoker for more than 40 years before beginning work on electronic cigarette technologies in order to help himself and others make the shift to vapor smoking. Dr. Han continues to market and conduct R&D in e cig related technologies to this date. History of...
Who Invented CPR?

Who Invented CPR?

Introduction CPR stands for Cardio-Pulmonary Resuscitation. It is one of the most important and universally practiced first-aid methods in the world. CPR is the only first aid treatment proven to save the life of a cardiac arrest victim until further help is arrives. Invention of CPR CPR was invented by Austrian surgeon Peter Safar. Safar was born in Vienna on the 12th of April, 1924. Both is parents worked in the medical profession. His father was a surgeon and his mother was a pediatrician. He studied medicine in the University of Vienna where he got his M.D. in 1948. Safer then specialized in surgery and oncology before traveling to Connecticut in 1950. There he studied at the Yale New Haven Hospital. Two years later he also completed studies in anesthesiology at the University of Philadelphia. Safar later got a job in Lima, Peru as overseer of the anesthesiology department there. Later he transferred to Baltimore, Maryland to do similar work. It was there he did research on current life saving techniques. Safer combined three existing methods in one: mouth to mouth resuscitation, head tilting and chest massage (or cardiac massage). These formed the basis for what will become the famous CPR technique. A humble man, Safar never tried to claim originality for his invention. He always said that he only put together techniques that were already known in his time. instead he worked hard to disseminate knowledge of CPR to as many people as people. He called the method “ABC” – for airway, breathing and heart circulation. Safar made progress in other areas of medicine as well. He helped build the biggest anesthesiology department in the country in Pittsburgh in 1961. There he devoted himself to improving critical care...
Who Invented the Parkland Formula?

Who Invented the Parkland Formula?...

Unanimously considered as the primary fluid resuscitation procedure for treating burn shock, the Parkland Formula is utilized in practically every burn center in the United States. It was invented by Charles R. Baxter, a doctor at the Parkland Memorial Hospital from which the formula got its name. Located in Dallas, Texas, Parkland Memorial has a place in history as the hospital where the three principal figures involved in the 1963 assassination of US President John F. Kennedy had died; namely, President Kennedy himself, suspected gunman Lee Harvey Oswald, and Oswald’s killer Jack Ruby. It was in fact then-emergency room director Baxter himself who unsuccessfully attempted to save Kennedy’s life. He also performed surgery on Texas Governor John Connaly, who had been injured during the incident. Dr. Baxter realized that severely-burned patients required an enormous amount of fluid in the first day of their treatment, particularly during the first 8 hours. It was in 1968 when he began developing the Parkland Formula based on studies he had conducted on animals and later tests on 11 burn patients. The method entailed administering Lactated Ringer’s (LR) at a rate of ml/kg/% burn, administering half the volume during the initial 8 hours and the other half over the following 16 hours, with the urine output being used as a clinical guide. Dr. Baxter would also specify that the plasma is to be administered at 0.3-0.5 ml/kg/% burn over the initial resuscitation’s fourth 8-hour interval; taking note that crystalloid in itself was not adequate enough to remedy the volume shortage. He would eventually report that the application of plasma had been based on research made with animals, and that employing the same process on human subjects did not evince a plasma volume increase superior...
