The inventions awarded Nobel prizes change the world medicine

Wilhelm Roentgen invented X-rays, Fred Banting and Charles Best found insulin for diabetes treatment, Karl Landsteiner system of blood groups in the body.

The Nobel Prize, first held in 1901, is awarded annually to outstanding individuals in the fields of physics, chemistry, medicine, literature, economics and peace. Nobel Prize by Swedish chemist Alfred Nobel, who invented the explosive, founded in 1895.

To date, the Nobel Prize has been awarded to many outstanding individuals with outstanding achievements. There are supposedly great inventions in history that change the world health, according to Nobelprize.

X-ray (Electromagnetic radiation)

On the night of November 8, 1895, after leaving the laboratory for a while, he remembered to forget to turn off the high-voltage circuit breaker that led into the cathode ray tube, Wilhelm Conrad Roentgen returned to the room and suddenly saw a green light trail on the table. the room is dark.

Scientific science Wilhelm Roentgen found the existence of a kind of invisible ray that could see through a light barrier, looking at the inner part of the human being, after 49 days in the laboratory.(Photo: Sciencehistory).

Realizing the strange, for 49 days, he stayed in the laboratory and finally found the nature of the secret ray he temporarily named X-rays.

After the X-ray was discovered, the scientist Roentgen used it to capture his wife's hand, when it was clear that the bones were burned and the wedding ring on her finger. This photo was introduced during the conference of the Wurtzbourg City Physical Society (Germany) in 1896 to demonstrate the ability of X-rays to penetrate through the human body.

Since then, X-rays have been widely used in medicine to identify problems related to bone structure. Today, X-rays are also the main tool in the field of imaging diagnosis, detecting organ problems in the human body.

In addition to medicine, X-rays are also widely used in industry and technical issues such as airport baggage screening. This work gave Wilhelm Röntgen the first Nobel Prize in physics in 1901.

Insulin hormones treat diabetes

Diabetes has been known since ancient times, described as a debilitating disease with the urine status of patients with sweet taste. At that time, there was no effective treatment. Diabetic patients quickly become mobile skeletons and often die prematurely due to severe weight loss.

In 1922, Fred Banting and Charles Best of the University of Toronto (Canada) experimented on dogs. They removed the dogs' pancreas, resulting in diabetes. This test sounds cruel, but has helped save millions of lives. Later, the scientists refined a chemical hormone from the pancreas and extracted many ingredients from Langerhan islet (called insulin). These substances were injected into dogs with diabetes for testing and diabetes was repelled.

In May 1922, Leonard Thompson, 14, was successfully treated at Toronto Hospital with this essence. News about the success of Banting and Best quickly spread. In 1923, two scientists Frederick Grant Banting and John James Rickard Macleod won the Nobel Prize for Medicine.

In 1928, scientists demonstrated that insulin is a protein.

Today, insulin injections become a mandatory treatment for diabetics, especially those with type 1 diabetes.

Blood type in human body

Austrian doctor Karl Landsteiner is known as the "father of immunology" when using his own blood to verify the hypothesis that different people have different types of blood.

Landsteiner thinks that humans have different types of antibodies in their blood. Some antibodies attack blood cells that contain other antibodies. When antibodies attack other types, causing the transfusion process to be interrupted, often leading to death.

In 1901, Landsteiner found four types of blood with his blood tests, namely: A, B, O and AB. Seven years later, the world's first blood transfusion was successfully performed in New York (USA). This is considered a great discovery in the history of world medicine, saving thousands of lives by blood transfusion method.

In 1930, Karl Landsteiner was honored in the Nobel Prize for Medicine for this achievement.
