[Functional morphology of capillary bed of the uterus after administration of synestrol]

The capillary vessels of rats uterus were examined. The animals who received 0.2% solution were examined 1, 3, 5, 10, 20, 30, 60 days after the last injection. As a marker for capillary vessels the histochemical method for finding the Mg++ adenosine triphosphatase was used. The studies have found prominent qualitative and quantitative changes (activity of enzyme, length and diameter of capillaries) not less than for two months after the last injection of the solution. Particularly prominent changes were found in endometrium between 10-20 days of the restorative period.
