Of root biomass was distributed in the soil 0～20 cm deep, 69.93% of that in the area 40 cm horizontally away from stem; 92.07% of leaf biomass on the plant part 3～6 m high from ground, 83.80% of that in the area 1 m horizontally away from stem; 84.05% of the stem and branch biomasses in the area 0.5 m horizontally away from stem.

97.48%的根集中于0～20 cm土层，69.93%的根分布于距干基40 cm的水平范围；92.07%的叶分布于3～6 m的垂直范围，83.80%的叶分布于距干基1 m的水平范围；84.05%的干枝分布于距干基0.5 m的水平范围。

Through the contrast analysis of the level of cell, protein and DNA, combined with the application of cladistic taxonomy system and numencal classification system and all the result of classification such as geographical distribution and fossil information, it can be deduced that the relationship of phylogenetics of Chinese crane is the following: the related relationship among Red crowned Crane , Black-necked Crane G.

通过细胞水平，蛋白质水平以及基因水平的对比分析，并结全宏观性状的支序分析和数值分析，以及地理分布化石资料等多方面分类结果推断，中国鹤类的系统发育关系是：丹顶鹤、黑颈鹤、白枕鹤、赤颈鹤的亲缘关系较近，而与灰鹤、白头鹤、沙丘鹤的关系较远，与白鹤、蓑白鹤关系最远。

Analysis of the relation between serotonin and its receptor in OFC and stress depression(n=8):(1) Microinjection of 5-HT into OFC significantly shortened immobility time, dejections have no great changes; though locomotor、 grooming activitives have little increased, they have no significant difference; rearing scores greatly reduced;(2)microinjection of pCPA into OFC significantly prolong immobility time, dejections have no great changes; locomotor、rearing activities are greatly reduced, but have no significant effect on grooming activity receding;(3)compared with the effect of 5-HT alone, microinjection of spiperone combined with 5-HT into OFC, significantly prolong immobility time and greatly reduced dejections; locomotor、 rearing、 grooming activities are all reduced, but have no significant differences.

眶额叶区5-羟色胺(5-hydroxytryptamine，5-HT)及其受体与应激性抑郁症的关系(n=8)：(1)注射5-HT后，大鼠FST不动时间明显降低(P＜0.05)，粪便数量变化不显著(p＞0.05)，OFT水平运动、修饰得分虽均有升高，但无显著性差异(P＞0.05)，垂直活动显著降低(P＜0.05)；(2)注射色氨酸羟化酶抑制剂-对氯苯丙氨酸后，FST不动时间明显增加(P＜0.01)，粪便数量无显著性变化(p＞0.05)，OFT水平、垂直运动显著减少(P＜0.05)，修饰降低但无显著差异(P＞0.05)；(3)与5-HT组比较，先注射5-HT_(1A)受体拮抗剂后再注射5-HT，FST中的不动时间明显增加(P＜0.01)，粪便数量显著减少(p＜0.01)，但OFT水平、垂直、修饰活动均有所减少，却无显著性差异(P＞0.05)。

Dy- namic levels on alanine aminotransferase,tumor necrosis factor and DHBV-DNA in sera of the duckings were determined.

给药组在第2次注射 LPS 后9、18、24、48和72h，与未给药组同期比较，血清 ALT 水平显著降低，血清 TNF 水平也明显下降，但血清 DHBV-DNA 水平无明显变化。

The results showed that OsAgpS1a transcripts and the reporter gene GUS driven by the OsAgpS1a promoter had a similar expression pattern that abundantly expressed in endosperms but very low in leaves, whereas OsAgpS1b transcripts and the reporter gene GUS driven by the OsAgpS1b promoter own other similar expression pattern that expressed at a low level in leaves, roots and early development endosperms of rice.

结果表明，两个启动子与其下游转录本的表达模式完全一致，即OsAgpS1a转录本和OsAgpS1a上游启动子控制的GUS基因主要在胚乳中高水平表达，在叶片中有很低水平的表达；而OsAgpS1b转录本和OsAgpS1b上游启动子控制的GUS基因主要在叶片和胚乳发育早期低水平表达。
