Do they exist as microdomains of heterochromatin, or are they some other form of repressive chromatin?

但是在活跃的基因中也可发现沉默基因的存在，这是否因为沉默基因存在于异染色质的 microdomain 还是他们以其它染色质的形式存在呢？

Apoptosis of lymphocytes in bone marrow, spleen, thymus and bursa was detected by light microscope, electron microscope and terminal- deoxynucleotidyl transferase UIP nick end labeling. The results showed ALV-J could induce incoordinate apoptosis of lymphocytes in thymus, bursa and spleen, which was mainly found in early time. And the apoptosis was much more obvious in thymus than in other immune organs.

Methods For the cosmetic purpose of 26 cases of full-cornea leucoma without visual acuity and of the leucoma deviated from pupil with better visual acuity, the lamellar keratoplasty plus interlamellar dyeing with tattoo-eyebrow liquid was adopted. The postoperative follow-up ranged from 1 year to 4 years (2.5 years on the average).

根据壳聚糖在阴离子染料染色时，可起到使颜色增深的作用特性，先用一定浓度的壳聚糖溶液对锦纶织物进行预处理，然后再用弱酸性染料进行染色，以提高其湿处理牢度。

Results showed:(1) The airway responsiveness of smoke control group was higher than that of normal control group, the airway responsiveness of smoke + exercise group was lower than that of smoke control group;(2) Plasma level of cortisol determined immediately after exercise was higher than that determined before exercise, no significant difference occurs between that determined next day morning after all exercise finished in contrast to that determined before exercise;(3) HE staining showed, there was severe chronic pulmonary inflammatory response in smoke control group, which was reduced in the smoke + exercise group;(4) chronic cigarette smoke downregulated the protein and mRNA expression of BKca in smooth muscles of bronchi and bronchioli, exercise increased the mRNA expression of BKca;(5) chronic cigarette smoke downregulated the protein and mRNA expression of Kv1. 5 in smooth muscles of bronchi and bronchioli, exercise increased both the protein and mRNA expression of Kv1. 5 in contrast to smoke control group in bronchioli and did not effect the expression of Kv1. 5 in bronchi;(6) chronic cigarette smoke induced upregulation of FIZZ1/RELMα in bronchial smooth muscle cells, exercise decreased these effect.

结果：(1)吸烟对照组的气道反应性明显增高，吸烟加运动应激可明显降低大鼠的气道反应性；(2)吸烟运动组运动后血浆皮质醇浓度明显高于运动前，但全部运动结束后次日晨测定的血浆皮质醇浓度与运动前无明显差异；(3)HE染色显示，吸烟对照组肺组织出现明显的慢性炎症反应，吸烟加运动应激组比吸烟对照组炎症反应轻；(4)慢性吸烟可降低大鼠大气道和小气道BKca mRNA和蛋白表达，而吸烟加运动应激可使BKca mRNA表达上调，但对小气道的蛋白表达无影响；(5)慢性吸烟可降低大鼠大气道和小气道Kv1.5蛋白和mRNA表达，在小气道吸烟加运动应激可减轻这种作用，大气道则无作用；(6)吸烟使支气管平滑肌的FIZZ1/RELMα蛋白表达明显增强，而吸烟加运动组的RELMα蛋白及mRNA均明显减弱。

The type of cell death caused by ricin was related to the ricin concentration and time of incubation with HeLa cells. The typical apoptosis was induced by ricin 0.05μmol〓. The apoptotic cells mainly showed cell shrinkage, cytoplasmic membrane blebbing, the chromatin condensation and fragmentation, crescentic nuclear and membrane bound apoptotic bodies formation.

细胞死亡方式也与蓖麻毒素作用时间和浓度相关，0.05μmol.L〓的蓖麻毒素可引起HeLa细胞发生典型的细胞凋亡，主要特征是细胞体积缩小，胞浆起泡，细胞核染色质浓缩、凝集，新月状核和膜包裹核染色质的凋亡小体形成。

The cation dyeable polyester fiber,which was developed by Do punt corporation in 1958 and commercialized in 1962 known as Dacron,is a main representative of new polyester fibers because of excellent dyeability and low cost.

阳离子可染聚酯纤维首先由美国杜邦公司于1958年研制成功，并于1962年实现商品化，商品名为达克纶，由于其优异的染色性能和低廉的染色成本，使它成为聚酯纤维新品种的主要代表。

Results In define induction envioroment, HPMSCS can diferentiate into lipoblast、after 2 weeks, the induced cells are full of lipid droplet;HPMSCS can differentiate into osteoblasts, after 4 weeks, we can see calcified tubercle in the cells, calcium in the calcified tubercle can be dyed black by Von Kossa and ALP dying is positive reaction above 95%.

结果 HPMSCS在培养基中持续培养后，在特定诱导环境下，成功使其向成脂肪细胞转化，培养2周时，可见融合成团的脂滴充满整个细胞；成功使其向成骨细胞转化，培养4周以上可见明显钙化结节，von Kossa染色可将骨结节中沉积的钙染成黑色，碱性磷酸酶染色呈强阳性反应达到95%以上。

Study showed that the copolymer fiber had good coloration (the temperature of coloring was reduced to about 90 degree). The colour fastness to crocking and colour fastness to washing were above four levels.

试验表明：这种共聚酯纤维有优异的染色性能，染色温度可以降低到90℃左右，且上染率可达90%以上；共聚酯纤维的耐摩擦牢度和耐洗色牢度均不低于四级。
