It was also found that the chromosomes paired well and formed a rod heteromorphic bivalent in the hybrid F1[73(36)9-1×CSDT 1BL]. Whereas 73(36)9-1 produced mainly configuration of 20''+1'+t' when test-crossed with CSDT 1BS. It showed that the translocation occurred on chromosome 1B short arm, and this segment came from rye chromosome 1RL. In the present paper we discussed also the way in which the translocation might be caused, and concluded that it was formed through reunion of two kind telocentrica (1BL and 1RL) after simultaneous misdivision of two univalent chromosomes (a wheat chromosome 1B, and a rye 1R).

同时还发现，73（36）9-1和"中国春"双端体的1BL能很好地配对并形成一个棒状的异形二价体，而它和CSDT 1BS的染色体则主要产生20+1′+t′的构型，从而证明易位发生的可能途径，推断是由于在F1花粉母细胞中的两个单价体（一个是小麦染色体1B，一个是黑麦染色体1R）同时进行错分裂之后产生的两种端着丝点染色体（1BL和1RL）重新并合形成的，因而冬小麦73（36）9-1可能是一个自发产生的易位系。

Be similar to most malignant neoplasms, the immortalization of TCCB cells is close relationship with telomerase and telomere of the end of chromosome.

与多数恶性肿瘤类似，TCCB细胞的永生化和染色体末端的端粒和端粒酶密切相关。

NAC4 mmol/L,CAT 80·U〓,NDMS 200μmol/L,and Quin 220μmol/Lcould down-regulate apoptosis as well as P53 expression variously induced by〓.

NAC和CAT不但本身可降低三种细胞的端粒酶活性，并可协同地促进〓对端粒酶的下调作用，而Quin2可抑制这种下调作用。

After salpingitis tubal atresia adhesion, mucosal cells in the secretion of fluid accumulation within the lumen, or isthmic tubal inflammation and adhesions umbrella side, blocking the formation of fallopian tube, when the lumen is absorbed within the suppurative cells , after eventually become liquid water.

在输卵管炎后，因输卵管粘连闭锁，粘膜细胞的分泌液积存于管腔内；或因输卵管炎症发生峡部及伞端粘连，阻塞后形成输卵管积脓，当管腔内的脓细胞被吸收后，最终成为水样液体。

We tested whether inhibitory GABAergic synaptic transmission regulates Xenopus optic tectal cell dendritic arbor development in vivo by expressing a peptide corresponding to an intracellular loop ofthe gamma2 subunit of type A GABA receptors GABA(AR, which is required to anchor GABA receptors to the postsynaptic scaffold.

我们想证明如下设想：抑制性GABA能突触传递是否能调节早蟾视顶盖细胞的树突发育。因为GABA受体的gamma2亚基有一段细胞内的跨膜端序列，这段序列对锚定GABAA受体到突触后膜是必须的，所以我们的主要方法是设计了一段特异性的争对细胞内段的序列，这样就特异性的阻断了单个细胞GABA能的突触传递。

The vas deferens can be divided morphologically into four parts includi ng proximal, mid, distal vas deferens and ampullae. The basic structure of the w all is similar in different parts of vas deferens.

结果表明，中国对虾的输精管可分为近端、中间、远端输精管及壶腹4部分，输精管壁各部分的基本结构相似，但分泌细胞的结构有较大的差别。

Research progress of anti-tumor mechanisms of ginsenoside Rh2（G-Rh2） extracted from ginseng was expounded,and the anti-tumor activity and mechanisms of G-Rh2 were discussed on regula-ting signal access system of tumor cells,reversing abnormal differentiation and tolerance of tumor cells,reducing telomerase activity of tumor cells,strengthening immunological ability,improving anti-tumor ability ,and interdicting synthesis and metabolism of tumor cellular important components etc.

论述了从人参中提取的有效成分人参皂苷-Rh2（G-Rh2）的抗肿瘤机理的研究进展，并探讨了G-Rh2在调节肿瘤细胞信号通路系统、逆转肿瘤细胞的异常分化与耐药性、降低肿瘤细胞端粒酶活性、增强机体免疫力、提高抗肿瘤能力以及阻断肿瘤细胞某些重要成分的合成与代谢等方面的抗肿瘤活性及其作用机理。

The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.

脱颗中的组胺等物质会引起毛细血管壁通透性的增加，进而引起组织液流动速度的增加和肥大细胞表面的切应力加大，这样会进一步促进肥大细胞的激活，从而释放更多的活性物质，这些物质一部分被静脉端毛细血管吸收进入血液，另一部分则随着组织液的定向流动向远处，并进一步刺激远处的毛细血管和肥大细胞，而组织液的定向流动途径和传统的经络线走向基本吻合，在宏观上就构成了循经感传现象。

Loss of telomere DNA repeats in eukaryotic cells is associated with senescence and apoptosis.

真核细胞端粒DNA序列的丢失与细胞的衰老及凋亡有关。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
