    • magic bullet is a chemical treatment that kills specific bacteria inside the body without harming the body.
    • Salvarsan 606 - the first magic bullet
      In 1900, Ehrlich put forward the concept of a magic bullet when he argued that a chemical could deliberately target bacteria in the human body and kill those bacteria.
      Ehrlich tested arsenic compounds to find a cure for syphilis.
      In 1909, a Japanese scientist called Sahachiro Hata retested all of the compounds and discovered the first magic bullet, Salvarsan 606.
      This was the 606th compound of Salvarsan (a drug containing arsenic), so it gave the drug its name.
      Salvarsan 606 was able to kill the bacteria that cause syphilis.
    • Prontosil - the second magic bullet
      In the 1930s, Gerhard Domagk used experiments on mice to discover that Prontosil killed the bacteria that cause blood poisoning.
      When his daughter developed blood poisoning after cutting her finger on a rose bush, Domagk was able to test Prontosil on a human being. She was the first human cured by a magic bullet.
      Scientists carried out a series of experiments and realised that Salvarsan 606 and Prontosil contained sulphonamide.
      Following this discovery, drug companies went on to develop sulphonamide cures for diseases such as pneumonia and scarlet fever.
    • MB693
      Developed in 1939.
      Used to cure Winston Churchill's pneumonia.
    • New Technologies in Treatments
      Mass production - supply & distribution of important medicines easier.
      Robotics - Better prosthetic limbs.
      Advanced x-rays - radiotherapy.
      Hypodermic needles - allows a precise dose of a medicine to be safely introduced into the bloodstream for faster effects.
      Capsules - dissolve in stomachs.
    • New Technologies in Diagnosis

      1890s - X-Rays - Help to see inside the body without cutting - identifies broken bones.
      1900s - Endoscopes - Small cameras on thin/flexible tubes to see inside the body, often to diagnose digestive issues. Can carry small surgical items too.
      1930s - Blood Tests - Non-invasive samples taken to be tested for lots of conditions.
      1940s - Ultrasounds - Use sound waves to make a picture of insides - identifies kidney stones/pregnancy/tumours.
      1970s - CT Scans - More advanced form of x-rays to diagnose tumours.
