Granulosus is further;2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes;3. A. mantzorum has well-differentiated XY type sex chromo-'.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.
结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。

The results indicated that chromosome counting was the most reliable and precise method, however, it was cumbersome and required skilled cytological techniques; The chromocenter size, heterochromatin number, chroloplast number of guard cell and certain plant morphological characteristics are simple and practical methods for ploidydetermination but with some shortages.
结果表明：对体细胞染色体的直接计数法是最可靠的方法，但费时、难度大；叶片气孔大小与倍性无显著相关性；保卫细胞叶绿体数目、体细胞染色中心大小以及异染色质个数与黄瓜倍性密切相关，是简单、快速而有效的倍性鉴定方法；植株的形态学观察也能间接确定植株倍性，但鉴定时期偏晚，精确性较差。

The results indicated that there was a evident correlationship between chromocenter diameter,heterochromatin number and plant ploidy level.The chromocenter diameter and heterochromatin number of haploid and double haploid are 5.1,5.0 μm and 13.3,11.9 μm respectively.
研究发现，黄瓜染色中心直径和异染色质数目与植株倍性呈正相关，可作为黄瓜倍性鉴定的间接指标，其中单倍体染色中心直径平均为5 1μm，双单倍体为13 3μm，单倍体异染色质数目平均5 0，双单倍体为11 9。

The results also indicated that there was a evident correlationship between chromocenter diameter, heterochromatin number and the plant ploidy level. The chromocenter diameter and heterochromatin number of haploid and double haploid are 5.1um, 5.2 and 13.3um, 10.7, respectively.2. Ploidy Determination in CucumberCucwm/5 sativus L.
同时研究中还发现，黄瓜染色中心直径和异染色质数目与植株倍性呈正相关，可作为黄瓜倍性鉴定的间接指标，其中单倍体染色中心直径平均为5.1um、双单倍体为13.3um，单倍体异染色质数目平均为5.2，双单倍体为10.7。

Cases of the abnormal sex differentiated diseases in children were presented. Among them, there were 4 cases of Turner's syndrome, 1 Klinefelter's syndrome, 9 female pseudohermaphroditism, 2 male pseudohermaphroditism, and 4 true hermaphroditism.
本文报道小儿性分化异常疾病20例(包括先天性卵巢发育不全综合征4例、先天性睾丸发育不全综合征1例、女性假两性畸型9例、男性假两性畸型2例、真两性畸型4例)，对上述病例进行了细胞染色体核型分析，同时作了口腔上皮细胞性染色质、中性粒细胞核鼓植体及尿17酮类固醇、17羟类固醇的检查。

Because more than 75. 4% regions were occupied by heterochromatin on the sex chromosomes of spiny eel, its X library should be a good tool to isolate the heterochromatic highly repetitive sequences DNA and study its origin and evolution.
在刺鳅的性染色体上，75.4％以上的长度都是异染色质区域，因此，刺鳅X染色体文库也为分离获得鱼类性染色体上异染色质重复序列，探讨其起源和进化规律提供了良好的实验材料。

The sex pheromone-producing gland of Ancylis.sativa Liu is amodified intersegmental membrane as a dorsal bag between eighth and ninthabdominal segments.
对枣粘虫雌蛾性信息素腺体的扫描和透射电镜观察表明，枣粘虫性信息素腺体是由第八、九腹节间的节间膜特化而成，是位于背部的一个囊状结构，它由两部分构成，前部的方形囊状体和后部的三角形囊状体，二者之间有一突起的脊；雌蛾静止时，腺体随第八和第九腹节一起嵌缩于第七腹节内，求偶时，腹部末端外伸，腺体细胞表皮外露，释放性信息素；腺体细胞呈方形，其表面覆盖几丁质表皮，表皮顶端无孔；细胞核很大，呈椭圆形，由双层核膜包被，位于细胞中下部，内有丰富的染色质；细胞质内有丰富的内质网，其内还有大量的大小不等的脂肪滴，以及线粒体和溶酶体等细胞器。

Furthermore, heterochromatinization should be an earlier event than pericentric inversion.
另外，从刺鳅的X、Y上结构异染色质的相似分布来看，在性染色体进化过程中，异染色质化发生的时间应该早于臂间倒位。
-
The chromatin unfolding assay showed that ,like the wild-type transactivation domain, two variants that represent benign polymorphisms did not induce chromatin unfolding or only induced subtle change. Contrary to the behaviors of the wild type and two benign variants, four cancer-predisposing mutations in the transactivation domain superactivate the chromatin unfolding. The results suggest that the chromatin unfolding assay can aid in the characterization of deleterious mutations in the C-terminal transactivation domain of BRCA1 and may provide more reliable presymptomatic risk assessment.
对这些重组质粒的染色质伸展活性检测表明，野生型pwt和两种良性多态性突变体不具有染色质伸展活性或只有极微弱的染色质伸展活性，而其他4种乳腺癌易感突变体均具有过强的染色质伸展活性，提示利用染色质伸展技术可预测BRCA1转录激活区基因型与乳腺癌发生风险的表现型的关系。
