Objective:To evaluate of the microstructure of the salivary glands of experimental animals born from of females rats, who were subjected to different modes of motor activity during the pregnancy: limited and compensated by regular moderate training. Material and Methods:The sample was composed 84 three-month-old descendants of Wistar rats which were divided into three groups: G1 (n = 27): posterity of female rats, who during gestation were in standard conditions; G2 (n = 25): posterity of female rats, who during pregnancy were in hypokinesia conditions; G3 (n = 32): which stayed in conditions of hypokinesia, but had running load in running wheel regularly 5 times a week. Results:In adult descendants of G2, morphological structure of the submandibular salivary glands was characterized by decrease size and number of glandular cells; reduction of their cytoplasm; increase in heterochromatin amount and decrease in the intensity of fuchsinophilia. Microstructure of the submandibular salivary glands of the offspring of G3 indicates positive effect of regular short-term physical activity on the morphofunctional state of the specified glands. An increased number of tissue basophils in their stroma is also in favor of greater functional activity of salivary glands. Conclusion:This study indicates deceleration of the metabolic processes in salivary glands of animals under the influence of hypokinesia of their mothers during pregnancy. It was also confirmed that regular physical activity completely eliminates the negative effect of mothers' hypokinesia on morphology the salivary glands of the descendant.
