Morphological observations of selected blood vessels of the uterine ligamentum latum in the swine during estrus cycle.
The structure of blood vessels in five points of the uterine ligamentum latum was to examined. Histological and histochemical methods were used as well as examining the internal structure of endothelium in the scanning electron microscope (SEM). The greatest changes occurred in the walls of the ovarian artery and vein, as well as in the branches of the uterine artery which torms arcuate anastomosis near the uterine horns. Differences concerned alkaline phosphatase (FZ) content, the presence of acid mucosaccharides, occurrence of laminae consisting of elastic fibres, changes of thickness of central membrane of vessels. Furthermore, occurrence of specific structures regulating blood circulation was seen. Observations in the SEM showed the occurrence ot differences in endothelium picture during the cycle.
