[The microcirculatory bed of the normal rat uterus and in exposure to laser radiation]

By means of scanning electron microscopy of corrosive casts angioarchitectonics of mucous and muscular membranes of the white rat uterus has been studied at diestrus phase, normal and under influence of laser irradiation with exposition of 1 min and 1 h. The morphometric investigation performed has proved presence of local peculiarities in organization of the uterine capillary bed. After irradiation for 1 min a noticeable increase in transversal diameter and capillary density is observed, numerous protrusions appear on their walls. When irradiation lasts for 1 h a relative loose of the uterine capillary network is observed, which is especially manifested in endometrium: capillaries demonstrate an increased convolution and decreased diameter.
