- Result The active component content in phloem was the highest, while, successively, in pith and in xylem. 结果大黄中的活性成分含量以韧皮部最高,髓部次之,木质部最低。
- Objective To explore genes involved in chronic myeloid leukemia (CML) with t(3;21) (q26;q22) chromosome translocation in blastic crisis. 目的探讨慢性粒细胞白血病(CML)急性髓系白血病(AML)变伴 t(3;21)(q26;q22)的受累基因。
- Results showed that the reducing sugar content in phloem was much higher than that in xylem, and a significant difference was found in the phloem of different poplar strains. 结果表明:各杨树品系木质部的还原糖含量远远低于韧皮部的含量,且韧皮部的还原糖含量差异显著。
- However, the expression of bFGF was decreased.We also demonstrated that angiogenin undergoes nuclear translocation in A375 cells. 另外我们利用免疫荧光实验进行了血管生成素的核转移分析,发现血管生成素在A375细胞中能够进行核转移作用。
- Deciduous shrubs or trees, rarely a woody climber, with white latex in phloem, turning black upon air exposure, polygamous or dioecious. 落叶灌木或乔木,很少一木质藤本,在韧皮部具白色乳汁,在空气中暴露会变黑,杂性的或雌雄异株。
- The image analysis,D-xylose absorbtion test and blood culture were used to measure the villus height and area,D-xylose absorption and bacterial translocation in blood. 方法:应用图像分析、D-木糖吸收试验和血培养等方法测定和评价移植肠绒毛高度、绒毛表面积、D-木糖吸收率和肠道细菌移位。

- The content of endotoxin in peripheral blood and the positive cases of bacterial translocation in MLN and liver of group D were less than group B and group C. 结果: D组大鼠的体重、肠绒毛高度、宽度及黏膜厚度比B组和C组明显增加;
- Angiogenin undergoes nuclear translocation in endothelial cells where it accumulates in the nucleolus and stimulates rRNA transcription, which is essential for angiogenesis. 已知血管生成素在血管内皮细胞中进行核转移作用,在核仁中发生积累并刺激rRNA的转录,进而诱发内皮细胞的增殖促进血管发生。
