[The effect of diabetogenic substances on the zinc and calcium content in the pancreatic islet cells of rabbits].

The injections of diabetogenic drugs to rabbits induced a decrease in zinc and calcium content in B insulocytes dependent on the degree of these cells damage and hyperglycemia. The content of these metals in A insulocytes was not significantly altered due to a light injury of these cells. A high concentration of calcium in islet A cells is suggested to be a protective factor to the action of alteration agents.
