８０年代以来细胞核仁形成萄银染程度已被公认为能够准确反映细胞中ｒＤＮＡ转录活性蛋白质合成水平的重要标志之一，业已确认细胞中核仁形成区可被银染的部分只能是那些具有生物活性并可以进行正常转录的ｒＤＮＡ区域周围的非组蛋白。本研究应用计算机图象分析系统，在国内多
Since the 1980s, the degree of nucleolus formation in cells has been recognized as one of the important markers that can accurately reflect the level of protein synthesis of rDNA transcriptional activity in cells. It has been confirmed that the nucleolus forming regions in cells can be stained with silver only by those with organisms. The non-histones around the rDNA region that are active and can perform normal transcription. This research uses computer image analysis system
