The Correlation Between DNA Ploid and Metastasis of NLN and Prognosis in NPC

鼻咽癌细胞核DNA倍体和颈淋巴结转移与预后的相关性

The addition of auxins ( NAA) and the cytokinins ( 6-BA) in NLN medium showed no significant effect on the frequencies of microspore-induced embryos, but when the concentration was excessive, the frequencies decreased.

NLN培养基中添加生长素（NAA）和细胞分裂素（6-BA）对小孢子胚诱导率影响不大，添加的浓度过大时小孢子胚诱导率反而降低；

Conclusion Ketoacid can decrease the serum BUN of LN and NLN patients markedly. Ketoacid can improve the nutritional state of LN patients, PA is a more sensitive index than ALB in reflecting the nutritional state.

结论酮酸疗法能够降低LN及NLN患者的血清BUN水平，血清PA是较ALB敏感的反映营养状态的指标，酮酸疗法能够改善LN患者的营养状态。

The correlation between various DNA ploid and metastasis of NLN and prognosis were analysed.
