顶端

Apical dominance is a common phenomenon in higher plants.

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成"前体腔上皮"，经再分化形成新的体腔上皮。

The TTB-USA we used in our study is the production of IBI corporation, it has two electrode at the tip of a 7F catheter, its tip and ablation temperature can be controlled.

本实验应用的是一种新型的超声球囊导管(through the balloon ultrasound ablation system，TTB-USA)，它将一个换能器安放在7F电极导管顶端，外面用一弹性良好的球囊包裹，在造影的引导下，把带有球囊的导管顶端置放于需消融处，用稀释的造影剂充盈球囊，然后发放超声波产生一个环状损伤，达到阻断电传导的目的。

Zigongdongdou, was used to investigate photoperiod effects on the development of terminal inflorescence of soybean, plant type and agronomic traits, with emphasis on the role of long-day in the formation of raceme. The plants were treated with short-day of 12h for 13 days to induce the initiation of terminal inflorescence, and then moved to 16h long-day treatment for 0, 1, 2, 3, 4 and 5 weeks, respectively. After LDT, plants were returned to SD condition.

为明确光周期特别是长日照对于短日照作物的生长发育及顶端花序发育的特殊重要作用，实验以光周期敏感的有限结荚习性晚熟品种自贡冬豆为材料，经过13天短日照处理(12小时)后，分别经过0、1、2、3、4、5周长日照处理，再在短日照处理下直到成熟，研究长日照对大豆顶端花序、株型及农艺性状的影响。

Leaves in opposite pairs, thin coriaceous, oblong, or phi needle-shaped, long 6-14 cm, the top length gradually sharp, pointed or slightly blunt wedge base, edges wavy or light wavy; petiole length 8-15 mm; stipule wide and triangular, was born in the Ministry of young vine at the top of drill-like long-tip , was born in the old vine, 3-6 mm long, the top regular convex tip.

叶对生，薄革质，矩圆形或披针形，长6—14厘米，顶端长渐尖，基部楔尖或略钝，边缘波状或浅波状；叶柄长8—15毫米；托叶宽三角形，生于幼枝上部的顶端钻状长尖，生于老枝上的长3—6毫米，顶端常凸尖。

Hyphae, loaded with CTC under pH 6. 8 condition and then grown in pH 8. 0 medium for a little while to destroy the apical acidification, could gave very diffuse fluorescence images of CTC membrame bound Ca〓 and vermiform fluorescence spots due to mitochondrias under pH 6. 8 no longer were clearly distinquished, which implied that besides mitochondrias, other cellular organelles with Ca〓 also were stained with CTC. Thus mitochondrias are not the only one intracellular Ca〓 storage, endoplasmic reticulums and Golgi bodies in the same zone may be also the Ca〓 storages. But the extreme apical zone under 2μm of the growing hyphal tip was still almost devoid of stain under pH 8. 0.The CTC fluorescence was concentrated in the subapic zone beyond about 2μm from the tip and then gradually became lower behind about 40μm from the tip. These results did not support the hypothesis which suggested that the cell wall vesicles in the extreme apical zone were intracellular Ca〓 storages.

将菌丝在pH6.8条件下负载CTC，再置于pH8.0培养介质中短暂生长一会儿以消散菌丝顶端的酸化区域，则CTC膜结合Ca〓呈现弥散的荧光影像，在pH 6.8培养条件下显示的蠕虫状的线粒体荧光斑点不再能够清晰辨认，说明除了线粒体之外，还有其它含Ca〓细胞器，也被CTC染色，线粒体并不是细胞内唯一Ca〓库，还可能包括内质网、高尔基体等细胞器，但菌丝最顶端2μm以前的细胞壁泡囊区域不能被染色，最大荧光强度仍位于菌丝顶端2μm以后区域，约45μm以后荧光变弱，实验结果不支持细胞壁泡囊为菌丝胞内Ca〓库的假设。

Results The tristar of groove was consisted of beak of the ethmoidal bulla and its prolonging process, apex of the uncinate process and anterior peak of the middle turbinate, at the region of frontal recess. The structures called meatal groove, uncinate groove and bullar groove were observed around the ethmoidal bulla and the tristar of groove located at their origination. Under endoscopic view these structures looked like a triangular clefts, so it was named.

结果 星状裂是由筛泡的顶端及其向上伸出的角、钩突的顶端、中鼻甲的前顶端在额隐窝区域汇合形成的一个星状裂隙，上述结构围绕筛泡形成鼻道沟、钩突沟、筛泡沟，星状裂为三条沟的起始部。

At the 10th day after cultivation, the visual pigment immunoreaction was suffusive in the whole cell membrane and apical process; while at the 30th and 40th day, it gathered at the membrane of apical process or one pole of the cells.

体外培养10 d时，视色素弥漫地分布于整个细胞膜及顶端突起；培养20 d时视色素逐渐向顶端突起或细胞的一端集中；到培养30、40 d时，视色素聚集于顶端突起或细胞的一端，呈现极性分布特征。
