title: Immediate effect of irradiation on microvasculature.
abstract: The immediate effects of irradiation on microvasculature in muscle in an animal model are described in this paper. By using triple isotopes of 125I, 131I, and 22Na, the transcapillary transfer of albumin from the vascular bed to the extravascular space is determined in terms of mg/g of tissue, after single doses of 2 to 14 Gy. These results reveal an increase in the extravascular albumin immediately after irradiation and suggest an instantaneous compromise in vascular permeability even after 2 Gy. This effect was apparently dose related.
