After irradiation of the heparinized rat blood with 0, 10, 50, and 100 Gy and duringthe different days following the whole-body exposure to 8. 5 Gy. PNP activities decreasedwhereas erythrocyte membrane lipid peroxidation increased.

• 其结果为:将大鼠抗凝血离体照射0；10；50和100 Gy以及全身照射8.；5 Gy后第1、3、5d；该酶活力下降而膜脂过氧化值却增加。
