From the 10th century, Chinese people took scabs of smallpox patients, crushed them and blew into healthy people's noses to prevent disease.In 1976, Dr. Edward Jenner was recognized as the first person to use the vaccine after taking cowpea disease against human smallpox.50 years later, the vaccine achieved a new development with the introduction of subcutaneous injections and this is the key to help Louis Pasteur successfully develop rabies vaccine.By the 1920s, diphtheria, whooping cough, tetanus and tuberculosis vaccines were available.Since 1980, smallpox is completely wiped out.
Galileo is considered the first person to invent a thermometer.But it was not until the mid-1800s that doctors could use thermometers to measure patients' body temperatures.In 1866, a 15cm compact thermometer was born.The first version comes in the form of a thin glass tube of mercury inside, attached to a piece of ivory or wood.
The field of cosmetic surgery only really developed when the skin implant technology achieved a certain achievement in the late 1800s. After 200 years, French scientists performed the first part face transplant in the world. .Today, medicine is able to fully implant patients.
From about 4,000 BC, people knew how to use herbal mixture with poppy flowers.By 1771, nitrous oxide was discovered.Chemist Humphry Davy identified this substance as a physical pain reliever, so it can be applied in operations where patients do not lose too much blood.Nitrous oxide is then used in extractions and then extended to other surgeries.
Apsirin is an old medicine.Ancient Egyptians used willow bark to treat aches and pains without knowing it was a natural aspirin named salicylic acid, which helps reduce fever and infection.In the 19th century, salicylic acid was made into a small tablet as we see it today.

Scientists have sought to transplant human and animal organs from the 18th century, but in 1869 the first skin transplant was performed.The second organ transplant took place in the mid-20th century. An important step in the transplant field is the successful production of cyclosporine anti-rejection drugs.
Accidentally discovered by Wilhelm Conrad Röntgen, X-rays allow doctors to see inside the patient's body without surgery.Unfortunately, some scientists were too impatient to use X-rays but did not measure the consequences.In 1904, an assistant of Thomas Edison died of skin cancer after a daily exposure to radiation.
