| bronze diabetes | A genetic disease in which the body takes in too much iron from food, this causes excess iron to be deposited in the liver and heart and other organs, eventually leading to organ failure and death. This illness is called bronze diabetes because the kidneys often fail, leading to symptoms similar to those found with diabetes mellitus, and because the deposition of iron into the skin makes the person look like he or she has an all-over tan. It used to be believed that this disease was rare and mainly affected people of Caucasian descent, butin recent years scientists have realised it is more common and affects a wide range of ethnic groups. Some believe that this genetic defect actually helps people (especially women) survive in areas where malnutrition is widespread and iron is scarce in food. Regular venesection may help people suffering from this disease. (09 Oct 1997) |

On account of its permanence in air and inertness to oxidation, it is used in the smaller coins, for plating iron, brass, etc, for chemical apparatus, and in certain alloys, as german silver. It is magnetic, and is very frequently accompanied by cobalt, both being found in meteoric iron. 2. A small coin made of or containing nickel; especially, a five-cent piece.
