Histochemically, the results indicated that POD activity increased with the growth rate of callus within the same tissue; and lignin deposit density within the cell wall increased with the growth of callus over time, displaying a trend similar to POD activity alteration upon Hg(superscript 2+) imposition; Furthermore, more tracheary elements was observed in the callus tissue subjected to Hg(superscript 2+) than that in control.

组织化学定位结果表明：同一处理样品的过氧化物酶活性随着愈伤组织的生长进程而逐渐增强，且与Hg(上标 2+)浓度呈正相关；细胞壁中木质素沉积随着愈伤组织的生长而增加，与过氧化物酶活性变化趋势一致；Hg(上标 2+)处理的愈伤组织中导管诱导率大于对照。

In a giving stage after pollination,p53 homologue showed high levels in the antipodal cells,integument,immature endosperm,ovary wall,tracheary elements,and aleurone layer,while c-myc homologue showed low levels in these tissues,only before pollination showed high expression in polar nucleus.

结果发现，在授粉后的一定阶段，在反足细胞、珠被、未成熟的胚乳、子房壁、导管组织和糊粉层中，p53同源基因表达强烈，c-myc同源基因的表达相反，在授粉后的这些组织中基本不表达，而在授粉前的中央细胞的极核中表达水平较高。

During the wall thickening, the number of Golgi bodies increased apparently and cytoplasm was filled with Golgi vesicles. Polylamellate structure of the secondary wall appeard, Along with the further development of tracheary elements, the nucleous disappeared and organelles were decreased, while cortical microtubules were arranged neatly against the inner side of plasmalemma.

初生壁与质膜之间有间隔较规律的次生壁突起；中期，线粒体和高尔基体的数量明显增加，细胞质中几乎充满高尔基体及其囊泡，次生壁中微纤丝已成有序排列；晚期，细胞核消失，导管中央形成空腔，细胞器迅速减少，仅观察到少量高尔基体和线粒体，有大量周质微管沿细胞长轴分布，且在次生壁的周围有大量小泡附着，次生壁的分层结构清晰可见。

Objective To investigate the application of transpulmonary thermodilution method during the peri- operation of simultaneous orthotopic liver and heterotopic pancreas- duodenum transplantations, and compare the efficiency in monitoring the preload of heart with improved Swan- Ganz CCO- SvO2 method.

目的：观察经肺温度稀释法在肝及其与肾、胰、十二指肠联合移植手术围术期的应用情况，并与改良式肺动脉漂浮导管比较反映心脏前负荷参数的有效性。

Methods: A new self- manufactured LAA occluder was implanted into the LAA through a transseptal catheter in 20 dogs.

用自行研制的新型左心耳封堵器经导管封堵20只犬的左心耳。

The TandemHeart percutaneous transseptal ventricular assist system is a left ventricular assist device designed to be used as a short-term circulatory support system for procedures not requiring complete cardiopulmonary bypass.

一种短期体外循环支持系统能够经由皮肤心脏导管手术，在30分钟内提供心脏辅助支持功能。TandemHeart经由皮肤跨隔膜心室辅助系统是一种左心室辅助设备，设计作为短期循环支持系统，不需要彻底的心肺通路手术。

Before the using of tremie it should be tested for water tight, with the water pressure of at least 1.5 times in the hole.

导管在使用前，进行水密试验，水压不小于孔内水深压力的1.5倍，不合格的不得使用。
