Top medicial descoveries in 20th century

      

      1. While vitamins were known to have existed before the 20th century, the only sources of vitamins were certain types of food. This is a problem for groups of people who live in conditions which limit the variety of the food they can eat. For example, crews on a ship would routinely develop scurvy due to Vitamin C deficiency. This was caused by a lack of fruit aboard the ship on especially long journeys. The British began bringing lemons and limes aboard on such journeys (hence the nickname “Limeys,”) and saw a decrease in the cases of scurvy at sea.

My opinion: it’s s true that vitamins exist in natural food, for examples but sometimes people are under nourished that’s why sometimes the people can’t  get adequate quantity of vitamins with natural foods. That's why they have to use the vitamins fills.

2.     Insulin was first isolated at the University of Toronto by Dr. Fredrick Banting. It had been known that the pancreas was involved in the disease diabetes since the late 19th century, but not until 1921 was it discovered that the hormone insulin could be used to treat type 1 diabetes. Until then such a diagnosis meant death for the patient. Banting and Charles H. Best made their patent on insulin available to all who could produce it in order to avoid prohibiting any production of this life-saving drug in any part of the world. That decision and their work have saved millions of lives all over the world and will save many more in the future. 

My opinion: when people are ill with diabetes them be necessary the insulin, because without it the people can be die and it’s discovery is very useful in medicine. And I can some interesting information about insulin: it’s a hormone normally created in the pancreas. This helps the muscles and tissues in the body to take a sugar (glucose) in the blood. If you do not have enough insulin in the body and thus becomes your blood sugar level is too high. The word comes from the cells of the pancreas, which is formed in the islets and islands in Latin Insula.

3.     Antibiotics are a very important part of modern medicine. Anti-bacterial soap prevents the spread of bacterial disease, antibiotics turn would-be dangerous infections into a small rash that goes away in about a week, and post-operative infections are minimal due to sterilizing efforts in operating rooms at hospitals and in doctors’ offices. All of these benefits stem from the discovery of Penicillin by Alexander Fleming in the early 20th century. Since then, medical research into the antibacterial effects of certain compounds and substances has led to the ability to prevent most bacterial infection in both everyday life and in the hospital setting, and in the case where an infection does occur the proper antibiotic medicine can be used to combat the infection.

My opinion: the antibiotics have a major role in a health, because with them we can prevent many infections and distributing them. Formerly it's had a large distribution and that’s why the people died premature.

4.     In 1895, Wilhelm Röntgen was experimenting with a new type of ray which he referred to as “X.” Little did he know that those rays would improve the lives and livelihoods of millions of people in the future. Röntgen discovered the medical application of X-rays when he photographed his wife’s hand, creating the first image of a human body part made by X-rays. The early tubes used to create the rays were very inefficient, but around 1920 a more efficient vacuum tube was invented, making way for wide spread use of X-rays for medical purposes. Today they are used to identify diseases mainly in bone, but also in soft tissue (pneumonia, lung cancer, kidney stones, etc.).

 My opinion: by inventing and using X-ray scanner, medicine had a big development.  In the past it was very difficult to found that diseases or factures, but now it’s very easy with x-ray scanner.
