几株细胞中期染色体NORs与间期核AgNORs活性比较

COMPARISION OF THE ACTIVITY BETWEEN METAPHASE CHROMOSOME NORs AND INTERPHASE NUCLEUS AgNORs IN SOME CELL LINES

对在咽癌细胞株ＨＮＥ＿３以及ＨｅＬａ、Ｒａｊｉ、人外周血淋巴细胞（ＰＢＬ）等的中期染色体ＮＯＲｓ表达及其间期核ＡｇＮＯＲｓ活性进行了对比检测与分析。染色体ＮＯＲｓ依次为８．２±２．８，１１．０±２．７，１４；６±４．３，１７．８±２．２．间期核Ａ８ＮＯＲｓ依次为３５．２±３．３，３２．３±３．１，２４．４±３．０，２．８±１．７。结果表明，染色体ＮＯＲｓ与问期核ＡｇＮＯＲｓ呈高度负相关（ｒ＝－０．９３３）。

Comparative analysis and test to NORs and AgNORs from nasopharyn-geal carcinoma cell strain HNE3 and other cell lines HeLa、Raji、PBL were made,The chromo-some NORs is respectively 8.2±2.8,11.0±2.7,14.6±4.3,17.8±2.2;The interphase nu-cleus AgNORs,35.2±3.3,32.3±3.1,24.4±3.0,2.8±1.7.The results showed that thereexist greatl negative correlation(r=-0. 933) between chromosome NORs and interphase nu-cleus AgNORs
