非整倍体的

DNA content of tumor cells was determined with flow cytometry in surgical samples from 36 patients, with esophageal carcinoma. The aneuploid was found in 25 cases (69.4％).

本文用流式细胞检测了36例食管癌切除标本的DNA含量，结果发现，DNA倍体水平差异较大，范围为1.68C～8.16C，大多数食管癌为非整倍体DNA含量，其中少数病人在同一标本中同时发现两种不同的非整倍体。

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。

That PI and the percentage of the cells in s-phase of the borderline/malignant and heteroploid/aneuploid tumors were higher ted to higher mortality and relapse rate as well as the corresponding risk. Because of the changable characters and dissociative phenomenon of the tumor, the measurement of PI and the percentage of cells in s-phase may be disturbed in few of diploid tumor and in part of double DNA stem ones. Therefore other paramet- ers should be added to analyse before making any conclu- sion.

交界性和恶性、异倍体或非整倍体肿瘤的PI和S期细胞百分率较高，病死加复发率和相对危险性增加；由于肿瘤的异质性和"分离现象"，对于少数2倍体肿瘤和部分双DNA干系肿瘤PI和S期细胞百分率的测定易受干扰，故应结合其它参数综合分析。

ELISA method was used for the serum PSA measurement among the 3o cases of PC sufferers. Results: 5 cases of NP were all ploidy (2C and 3-4C); 23 out of 30 PC cases were euploidy. As PC levels increased, the ploidy rate increased accordingly; in 25 cases of PC sufferers, the serum PSA was higher than normal; in 6 Out of 7 ploidy sufferers, the serum PSA was abnormal; 4 out of 5 normal PSA are euploidy.

结果：5例NP中均为整倍体（2C和3-4C），30例PC中有23例出现非整倍体，并且随着PC分级的增高，其倍体率也增大；25例前列腺癌患者血清PSA值高于正常值。7例整倍体患者6例血清PSA不正常，5例PSA正常者中4例为非整倍体。

Aneuploidy is that cells or individuals possess abnormal chromosome number resulted by nondisjunction during cell division .

非整倍体指染色体分离异常所导致的染色体数目非整倍性改变所得到的细胞与个体。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

Progeny of this plant included aneuploids, such as trisomic and tetrasomic.

这一异常植株的花粉母细胞仍为混倍体，其子代中有二倍体和各种非整倍体植株。

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

Some approved aneugens Trip terygiuwlIypogaucum (evelHutch, colchicine, thiabendazole, a tropine sulfate,d-ubocurarine was added into the reactive system respectively and the changes of their absorption values were taken down during different periods under the conditions of 37 0C and 350nm .

本研究通过多步聚合和解聚合反应从猪脑中分离纯化微管蛋白，建立微管蛋白的体外聚合和解聚合反应平衡体系，并将已证实的非整倍体诱发剂（昆明山海棠根部水抽提物、2-（4′-噻唑）苯丙咪唑、硫酸阿托品、d-筒箭毒碱）分别加入此反应平衡体系中，于37℃、350nm条件下，记录此体系不同时期的吸光值变化，与阳性对照物和溶剂对照处理平衡体系后的吸光值在相同时间点作比较，以此评估这几类非整倍体诱发剂对离体条件下的微管蛋白聚合的影响，寻求这几类非整倍体诱发剂是否可通过抑制微管蛋白聚合作用途径而诱发非整倍体。

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.
