异倍体的

The research progress on synthetic allopolyploid including type, inducement method and utilization status in crop genetic improvement were summarized, and the feasibility and importance for using it to improve crop varieties were discussed. Finally, the existing problems in relevant researches were analyzed, and the future studies were prospected.

概述了近年来植物人工异源多倍体的研究进展，包括人工异源多倍体的类型、诱导方法及其在植物遗传改良中的应用现状，探讨了利用人工异源多倍体进行农作物品种遗传改良的可行性和重要性，并对相关研究中的问题进行了分析和展望。

There was also not any haploid metaphases (n=16 or 19) was detected in hybrids. However, about 1-2% metaphases observed in this study was allopolyploid. GISH proved that they was made up of haploid genomes of M. nobilis (n=16) and triploid genomes of C. farreri (n=57). GISH was also employed to detect different chromosome components and identify donor chromatin in hybrids between C. farreri♀×A.

但我们检测到了约1-2%异源多倍体的分裂相，GISH分析后发现这些分裂相是由单倍的华贵栉孔扇贝的染色体和多倍的栉孔扇贝染色体组成，比如论文中图示了一个异源四倍体的分裂相，它是由单倍的华贵栉孔扇贝的染色体(n=16)和三倍的栉孔扇贝染色体(3n=57)组成。

Results:(1)Dietary selenium might inhibit the formation of aneuploid cells in Wistar rats glandular stom-ach.

结果：(1硒能抑制MNNG所致大鼠腺胃粘膜细胞异倍体的形成。

Objective To evaluate the clinical significance of the detection of DNA aneuploid and telomerase activity in the diagnosis and differential diagnosis of malignant pleural effusion.

目的 了解不同类型胸腔积液表达DNA异倍体和端粒酶活性的差异，探讨DNA异倍体和TA诊断与鉴别诊断恶性胸腔积液的价值。

The analysis of AL, especially ALL aneuploid, by image analysis system can be helpful in distinguishing the high risk ALL from the standard risk ALL ,and the determination of cell cycle distribution can provide a crucial reference data for chemotherapy.

图像分析系统对AL尤其是ALL异倍体的分析，有利于判断高危ALL，对细胞周期的测定给化疗个体化提供了具体的参考指标。

The tumors with double DNA heteroploidies (3cases) were much more malignant in nat- ure than those with diploidy + heteroploidy.

双异倍体干系肿瘤（3例）的性质极恶，2倍体加异倍体肿瘤的行为略好。

The rates of the heteroploidy and aneuploidy rose gradually in the shift of benign- borderline-malignancy, and the same was true for the rat es of mortality/relapse as well as the contrast risk. The nature of ovarian tumors with heteroploidy was much malignant than that with diploidy.

在良性、交界性至恶性肿瘤系列中，异倍体率或非整倍体率明显增加，病死和复发率及相对危险性随之增高；异倍体肿瘤的性质较恶，2倍体肿瘤趋于良性。

VCM increased the HRPE cells' proportion of phase S (6％～13％)and heteroploid was found in VCM with 250 and 500 mL/L vitreous.

VCM促使更多的HRPE细胞进入了DNA合成期（S期，6％～13％），含250与500mL/L玻璃体体积的VCM使HRPE细胞出现了异倍体的改变。

The results showed that 69.0%of small HCC and 87.6%of large HCC had heteroploid DNA content. The difference of the rate of heteroploid between the large HCC and small HCC was statistically significant. However, no correlation was found between DNA content, pathologic staging and Vmax RI of the arterial blood flow.

结果表明：小肝癌异倍体发生率为69.0%，大肝癌异倍体发生率为 87.6%，两组间异倍体发生率有显著性差异，但内部及外周动脉血流的有无及其最大流速、阻力指数的高低与异倍体发生率、病理分级无显著相关。

If 〓mRNA positive expression, its DNA heteroploid type display as triploid or hypodiploidy, if 〓mRNA negative expression, its DNA heteroploid type display as hyperdiploidy、tetraploid or Bistem line. These from one flank demonstrate the role of 〓 gene suppress the proliferation of malignant tumor

表达阳性者，其DNA异倍体主要表现为三倍体或低二倍体，〓表达阴性者，其DNA异倍体主要表现为高倍体、四倍体和双干系，从一个侧面显示出〓基因的抑制恶性肿瘤细胞增殖的作用。

I can not make it blossom and suits me

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
