Abstrakt:	Structural organization of the microcirculatory bed and mast cells in the uterus of mature female Wistar rats (n=60) were examined every 2 h over 24 h. During night hours, many vessels characterized by intensive reaction to NADPH-diaphorase and endothelial NO synthase were detected in the endometrium, and the density of these vessels and mast cells was quite high. During the day and evening hours, the capillaries with high levels of enzymes involved in NO synthesis and mast cells were less numerous. NO directly regulating the diameter of arteries and the intensity of transcapillary exchange can act as a signal molecule in the temporal dynamics of the vasoceptive action of estrogens and their receptors in the uterus.
