Abnormal Insulin Secretion in Adult Canines

Summary

Insulin secretion after intravenous administration of glucose was studied in fourteen dogs, twelve of which were four years of age or older. Based on several characteristics of insulin secretion kinetics, normal and impaired insulin responses were defined in the experimental subjects. Among those, five exhibited a marked depression of the initial stage of insulin release which was followed by a stage of relative hyperinsulinemia. Similarities between canine and human insulin secretion patterns were noted, and the potential usefulness of the procedure for the early detection of canine diabetes mellitus discussed.
