- 方法 將Wistar大鼠 隨機分為5組,除空白對照組外,其余4組均經(jīng)免疫抑制處理(注射阿糖胞苷與60Co全身照射),皮下接種胃癌細胞 懸液,制成胃癌大鼠模型。Methods The Wistar rats were randomly divided into five groups. Except for normal control group, the other four groups were injected Arac and radiated with 60Co, then transplanted with BGC-823 gastric cancer cells to form gastric cancer rat models.
- 利用60Co輻射誘變,選育出一株正突變菌株R4-5-27,在同等發(fā)酵條件下,生物量達到10.25mg/L,鐵含量7.43mg/g,總鐵含量為76.16mg/L,比出發(fā)菌株提高了1.59倍。In the same measure , the biomass was 10.25 mg/L, iron content of the yeast cell was 7.43 mg/g.
- 針對ROSEM、代數迭代算法(ART)和卷積反投影算法(CBP),分別做了模擬實(shí)驗和實(shí)際汽車(chē)CT檢測以及集裝箱CT檢測實(shí)驗,并分析比較了它們在60Co集裝箱CT檢測中的應用。Performances of ROSEM,CBP and ART are analyzed on both Sheep-Logan digital phantom and the ~(60)Co Container inspection system. ROSEM exceeds ART in both speed and image quality,but exhibits a slower speed than CBP.
