| 目的 比较 3H-TdR与 125I-UdR掺入淋巴细胞的增殖效应。方法 用 3H-TdR与 125I-UdR掺入法测定淋巴细胞和Daudi淋巴瘤细胞的增殖效应。结果 3H-TdR和 125I-UdR在正常淋巴细胞中的掺入率分别为20.95%±1.06%和1.00%±0.04%,在Daudi淋巴瘤细胞中的掺入率分别为29.94%±4.10%和6.02%±0.73%。 3H-TdR在细胞中的掺入率明显高于 125I-UdR;且 3H-TdR和 125I-UdR在淋巴瘤细胞中的掺入率高于正常淋巴细胞。结论 就淋巴细胞而言,作为示踪剂 125I-UdR不能替代 3H-TdR;但对于淋巴瘤细胞,能否代替 3H-TdR有待于进一步研究。 |

| Objective To compare the incorporation method of 3H-TdR and 125I-UdR on determining the proliferation effect of lymphocytes.Methods The proliferation effects of lymphocyte and Daudi lymphoma cells were estimated by 3H-TdR and 125I-UdR incorporation. Results The incorporating fraction of 3H-TdR and125I-UdR into lymphocyte was 20.95%±1.06% and 1.00%±0.04%, respectively, and the incorporating fraction for the lymphoma cells was 29.94%±4.10% and 6.02%±0.73%,respectively. The incorporation fractions of 3H-TdR into lymphocyte and lymphoma cells were much higher than those of 125I-UdR, but the incorporating fractions of 3H-TdR or 125I-UdR into the lymphoma cells were much higher than those of lymphocytes. Conclusions For lymphocytes, 125I-UdR cannot substitute 3H-TdR as a tracer agent. But for lymphoma cells, whether 125I-UdR could be replace 3H-TdR or not needs further research. |
