Scientists have found that ruined famous Arctic expedition.
The cause of death of the Arctic expedition of John Franklin could be tuberculosis, which led to Addison’s disease – chronic adrenal insufficiency, scientists say.
The findings were published in the journal Arctic.
The ships of the expedition of John Franklin in the Arctic region, held in the years 1845-1847, was nipped in the ice near the island of king William, and the members of the team, despite the supplies of food, killed one another for unknown reasons.
There are many versions about what killed the Franklin expedition: hunger, scurvy, botulism, lead poisoning. Professor of dentistry Russell Taichman noticed that in the descriptions of the members of the expedition mentions “dried black mouths”. Brown plaque on the teeth and tongue associated with adrenal insufficiency, it appears due to the destruction of red blood cells and the development of iron deficiency.
In the years of the expedition tuberculosis was a widespread disease. Without proper treatment it could result in the failure of the adrenal glands. In favor of this version says also that from tuberculosis, as shown by the autopsy, killed the three sailors who were on the ship.
Other factors, such as scurvy and lead poisoning, could contribute to the development of the disease, but was not directly the cause of death of the members of the expedition, the researchers said.
