Damaging action of prolonged gamma irradiation on microvessels in mesentery of a small intestinal rat

The research of a condition of microcirculation in mesentery of a small intestinal rat, is total irradiated in a total doze 2.5 Gy within 20 day for 0.125 Gy/day, has shown, that in early period after a prolonged irradiation at 80 % of animals the violations blooding are observed, are expressed the hemorrhagic exhibiting around venules and stain the hemorrhagic, sludge, stases in fine vessels. The received data testify, that prolonged gamma-radiation of animal in non mortality dozes can result in the functional and structural changes shown and in remote terms. The results will be coordinated to the data of other authors, which studied a condition of vessels after an irradiation in small dozes by other methods and on other bodies.
