Abstract:

The sharpest increase of vascular permeability following irradiation of rabbits 1,000 r takes place in the first hours after the action of ionizing radiation. At this time there is seen a sharp increase in the quantity of intravenously injected fluorescine in the anterior chamber of the eye, as compared to normal conditions. The resistance of the capillaries of the rabbits small intestine in relation to external pressure causing hemorrhages in the intestinal wall drops more markedly during the late stages of radiation sickness. The period of largest changes in vascular resistance coincides with the time of appearance of hemorrhages in the internal organs of the animal. Author
