A typhoid outbreak, endorphins and the world’s first MRI scanner are some of the North-east milestones being marked as the NHS in Scotland turns 70.
Since its creation on July 5, 1948, the NHS in Scotland has seen a number of high-profile achievements in research.
A new interactive timeline has been created to mark the special anniversary highlighting three moments since the 1960s which took place in the North-east.
The Aberdeen typhoid outbreak in 1964 sparked a major public health scare for the NHS, attracting huge media attention in the new era of television.
Caused by a single large can of Argentinian corned beef, it would see more than 500 people hospitalised over a four-month period.
The incident would lead to the creation of The Scottish Communicable Diseases Unit, which would lay the foundations for the establishment of the Food Standards Agency.
The discovery of enkephalins, later called endorphins, at the University of Aberdeen also features on the timeline.
In 1975, Hans Kosterlitz and his colleague John Hughes were the first scientists to identify the morphine-like chemicals produced naturally by the brain.
On August 28, 1980, an elderly Fraserburgh man became the first patient in the world to get a whole body MRI scan– the third North-east achievement to feature on the list.
Magnetic Resonance Imaging (MRI) was developed by a team from the University of Aberdeen headed by Professor John Mallard, later made a Freeman of Aberdeen.
Around 25,000 MRI machines are now in daily use around the world.
Health Secretary Shona Robison said: “I am delighted to see our NHS reach such a significant anniversary and I hope all of Scotland will join the celebrations this year as we pay tribute to everything it has achieved.”
