查询词典 x chromosome

The major clinical manifestation was lymph node enlargement found in all patients. Skin involvement and osteolysis were not frequent. The characteristic finding was leukemic cells with highly indented or lobulated flower-like nuclei in peripheral blood and bone marrow. ATL cells were CD2,CD3,CD4,CD25 positive and CD8 negative. No specific chromosome abnormality or HLA type was found. Seven of 8 patients examined had HTLV-Ⅰ antibody. The HTLV-Ⅰ provirus genome sequence integrated into host cell DNA was amplified by PCR and confirmed by liquid hybridization. All of these results showed that HTLV-Ⅰ was also the etiological agent of ATL in China. One of the 9 cases of ATL was classified as lymphoma type, one as chronic-type, and the rest as acute type.

结果和结论确诊9例ATL，其临床特征主要为淋巴结肿大，皮损及溶骨改变少见，外周血及骨髓出现典型的花瓣状核淋巴细胞，胞体大，核畸形，免疫表型为CD-1、CD+2、CD3+、CD4+、CD-8，还表达CD25等激活标记，染色体核型及HLA分型未发现有规律性的变化。8例ATL中有7例血清HTLV-Ⅰ抗体阳性，应用PCR及液相杂交法可检出整合到宿主细胞DNA中的HTLV-Ⅰ病毒序列，表明在我国HTLV-Ⅰ也是ATL的病因。9例中1例为淋巴瘤型，1例为慢性型，7例为急性型ATL，治疗效果及预后均不良。

The results suggest: 1 during the transition of gametes to zygotes, the activation of the embryonic genome appeared relatively indiscriminate; It＇s reasoned to be due to the histone-protamine exchange occurred in male pronuclei and the dramatic changes in the chromosome structure happened during the first run of embryonic DNA replication, which caused the inappropriate and un-selectively ie.

在配子到合子的转变过程中，胚胎基因的激活可能是一个相对无序的、随机的过程。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

The parental origin of extra chromosome 21 was determined by comparing genotypes of probands with their parents.

根据患者及其父母基因型的比较来确定21号额外染色体的双亲起源。

Polytene chromosome structure is a characteristic of some polyploid cells where several to thousands of chromatids are closely associated with perfect alignment of homologous DNA sequences.

多染色体结构是多倍体细胞的特征。在多倍体细胞中，有几个至几千个染色单体与相对应的DNA序列精确结合。

The results show that chromosome karyotype and character of DNA molecule can be effectively applied in the classification of planarians Dugesia.

结果表明：染色休和分子分类特征可以有效地辅助三角涡虫的分类。

In this study, the chromosome karyotype analysis and RT-PCR method are employed to explore the taxonomic characteristic of the planarians.
