[Quantitative histologic studies of mast cells in the parathyroid gland of sand rats (Psammomys obesus) during the development of a mellitus syndrome].

Mast cells in the parathyroid glands of sand rats with different disturbances of the carbon hydrate tolerance (reference, impaired-glucose-tolerance, and diabetic group) are quantitative-histologically investigated. In the IGT-group (impaired glucose tolerance), mast cells are significantly increased. However, the number of this cells in the diabetic group is significantly decreased. This investigations demonstrate that the mellitus-syndrome is not only a complex neuroendocrine disturbance but also a disturbance of biogenic amines and the organ of the connective tissue.
