| 中文摘要: |
| 本实验观察了不同剂量(0,50,75,150mGy和2,4Gy)X射线单次全身照射昆明系小鼠后腹腔巨噬细胞(MΦ)对鸡红细胞(CRBC)吞噬消化功能的影响。其结果表明：50和75mGy照射后3和5天巨噬细胞对CRBC的吞噬功能有非常明显增加(P<0.01),75mGy照射后巨噬细胞其消化功能也非常显着(P<0.01),而2和4Gy照射后其吞噬和消化功能降低。 |
| 英文摘要: |
| This study was undertaken to observe the effects of single whole body irradiation with 0, 0.05,0.075,0.15,2.0 and 4.0 Gy of X-rays on the function of peritoneal macrophages from Kunming mice in engulfing and digestion of chicken red blood cells (CRBC). The results showed that the engulfing functions of macrophages on CRBC 3 and 5 days after irradiation with 0.05 and 0.075 Gy increased obviously,and their digestive function after irradiation with 0.075 Gy was significantly higer than that in 0 Gy group. However,their engulfing and digestive functions decreased after the irradiation with 2 and 4 Gy.These results suggest that low dose radiation can stimulate the function of nonspecific immunity while large dose radiation can inhibit it. |
