查询词典 progenitors

Can accelerate the bone marrow cell from G1 phase into S phase when we measure it's Cell cycle, it make S phase rate was increased .thus it promoted DNA synthesize and repaired. Mice irradiated at dose of 5.5 Gy gamma-irradiation showed timed-related decreases and restores in peripheral blood picture at day 1 through day 21, the counts of WBC of these group had taken drug has various degree to increase than irradiation control group in day 1. Grugs failed to protected the peripheral blood cell at lowest point, but seems promote their rescovery.9803 treated group was distinct. At 7days after mice were radiated in 3.5 Gy. we observed drug can Significantly hold back the decreased number of hematopoietic progenitors colony forming radiation induced. These findings indicated 9803 have a certain radioprotective activity against gammer irradiation in mice.

给药组的 CFU-S 数量较照射对照组明显增加，3.5Gy 照后第七天观察给药9803组对小鼠骨髓造血组细胞集落生成能力的影响，给药组的造血祖细胞集落的形成能力强于照射对照组，并且9803组明显优于523组。5.5Gy 照射引起的小鼠的外周血细胞数量的降低以 WBC 发生最早，照后24小时给药组的 WBC 数量均比照射对照组有不同程度的升高，以9803各给药组最为明显，药物未能使照射引起的外周血细胞最低值升高，而有降低的趋势，但给药对照射后期外周血象的总体恢复有较好的促进作用。7.5Gy 照射后第七天测定小鼠骨髓细胞周期的测定中发现9803具有促进骨髓细胞由 G1期进入 S 期的效应，致使 G0/G1期细胞显著减少， S 期细胞比率显著增加，这利于促进 DNA 合成修复，即促进骨髓细胞增殖，骨髓细胞 DNA 含量给药组显著高于照射对照组。

The present study is to culture otocyst cells in fetal, cochlear sensory epithelial cells of neonatal and mature respectively in vitro with refinement of culture media and techniques. Immunocytochemistry and Bromodeoxyuridine labeling are used to detect properties and mitotic status of cultured cells. With the observations about proliferation and differentiation in cultured cells, we want to find the origin of regenerative cells and to understand how these progenitors proliferate and differentiate.
