摘要

研究了振荡铱源腔内照射对大鼠乙状结肠直肠慢性辐射损伤与剂量、剂量率和照射体积的关系。大肠狭窄的发生率随剂量、剂量率和体积的增加而增加。导致50%狭窄发生率的标称剂量分别为27gy (2gy /min)、32.5 Gy (0.2 Gy/min)和51gy (0.05 Gy/min)。

[Chronic radiation sequelae in the rat rectum following intracavitary irradiation with different doses].

The dependence of chronic radiation damage of the rectosigmoid on dose, dose rate and irradiated volume after intracavitary irradiation with an oscillating iridium source was studied in rats. The incidence of large bowel stenosis increased with increasing dose, dose rate and volume. The nominal dose leading to 50% incidence of stenosis was 27 Gy at 2 Gy/min, 32.5 Gy at 0.2 Gy/min and 51 Gy at 0.05 Gy/min.
