Summary It is reported that concanavalin A (conA) and wheat germ agglutinin (WGA) have a differential binding pattern on normal mouse spleen lymphocytes and the surface of Dalton's lymphoma cells. It is suggested that sialic acid on the cell surface controls the expression of lectin binding sites. Further, it has been observed that the increased release of sialic acid from cell surfaces aftercis-dichlorodiammine platinum (II) (cis-Platin) treatment is due to the increased activity of sialidase.To whom reprint requests should be addressed. 相似文献

目的探讨不同治疗方法及肿瘤侵犯范围对鼻腔非霍奇金淋巴瘤(NHL)预后的影响。方法对106例鼻腔NHL患者进行回顾性分析。结果本组病例中位生存46个月,5年总生存率为55%,5年无病生存率为50%,局部控制率92.5%。肿瘤侵犯范围对总生存率、局部控制率和远处侵犯率有显著影响;放疗+化疗的综合治疗对单纯放疗或单纯化疗,5年生存率、5年无瘤生存率、远处侵犯率有明显差异(P〈0.05);化疗周期和放疗剂量的不同可引起上述指标差异(P〈0.05)。结论肿瘤局部侵犯范围、化疗周期和放疗剂量是影响鼻腔NHL生存率,局部控制率和远处转移率的重要因素。合理的鼻腔NHL治疗模式应以放疗为主,辅以化疗的综合治疗。不必常规行颈部预防照射。 相似文献

The variable domain of heavy chain (VH) and light chain (VL) genes of anti-CD20 monoclonal antibody HI47 were cloned from anti-CD20 ScFv expression vector pCANBTEcd20 by PCR and ligated into vector pYZF to construct chimeric anti-CD20
Fab’ fragment expression vector pYZFcd20. Chimeric anti-CD20 Fab’ fragment was expressed inE. coli 16C9 and purified by protein G affinity chromatography. Competitive inhibition assay showed that anti-CD20 Fab’ fragment
inhibited binding of HI47 to CD20 on the surface of Daudi cells. Results from MTT assay indicated that chimeric anti-CD20 Fab’ fragment inhibited the
proliferation of Daudi cells, IC50 = 69 μg/mL. Affinity of chimeric anti-CD20 Fab’ fragment was determined, Ka was about 8.9×108 (mol/L)−1. 相似文献

A substance with antiproliferative bioactivity in an aqueous extract ofCordyline terminalis was purified and identified by mass spectrometry to be the natural nucleoside, thymidine. 10–5M Thymidine inhibited EL4 cell replication and decreased cell viability after 12–24 h. The effect was highly specific for this nucleoside. Treated cell cultures showed a significant increase in S phase cells and a corresponding decrease in G1 phase cells. Nitrobenzylthioinosine (which prevented facilitated entry of thymidine) protected cells from the antiproliferative action of thymidine. A human breast cancer cell line (MCF7) was also growth-inhibited by 10–5M thymidine but a murine lymphoma cell line (K36) was not. Thus, submillimolar thymidine has effects on cell proliferation which are selective both with respect to specificity for the compound and for different tumour cell lines. 相似文献
