Keywords: diabetes mellitus; submandibular gland; hemocapillaries.

Introduction. According to the International Diabetes Federation the number of patients with diabetes mellitus (DM) continues to grow rapidly. It has been established that already in the early stages of DM dysfunction of the vascular endothelium occurs leading to the development of diabetic microangiopathy that, in turn, results in dysfunction of salivary glands. The submandibular gland is considered to be the main source for basal secretion of saliva and its dysfunction in case of DM results in the development of xerostomia. However, the features of morphological changes of its hemocapillaries in this pathology have been insufficiently studied.

The aim is to establish the features of ultrastructural restructuring of hemocapillaries of the submandibular gland in case of experimental DM.

Materials and methods. In the Wistar rats DM was induced with streptozotocin (6 mg / g body weight). Submandibular gland's capillaries were investigated on the ultrastructural level and their morphometric parameters were measured.

Results. During experiment were observed structural changes in the basement membrane and morphometrically its thickening was increasing. Since 42^nd day destructive changes of endothelial cells have developed manifested, shape factor of the lumen of capillaries was decreasing that indicating pronounced diabetic microangiopathy of the submandibular gland. In later stages (56 – 70 days) destructive changes have increased, morphometrically were confirmed the thinning of transport area of endothelial cells and greater decreasing of shape factor of hemocapillaries lumen.

Conclusions. Hemocapillaries of the submandibular gland are sensitive to pathogenetic factors developing in DM and dependent on its duration.
