Recently, it is proved that SP is also involved in pain modulation, acupuncture analgesia and immunoin- hibition. However, the role of CGRP in them is unclear Therefore, the dy- namic changes of CGRP-, SP-like immunoreactivity and expression ofα- CGRP,β-CGRP mRNAs in dorsal root ganglion and spinal cord in the arthritic rats were observed by using immunohistochemistry and in situ hybridization techniques combined with behavioral tests, respectively. Subsequently, the effects of this peoptide on the develoment of polyarthritis were investigated by intrthecal injections of CGRP and its antagonist in the rats. In addtion, GAL is a novel neuropeptide which coexists with CGRP and SP, but it may play a different role in the primary sensory system. Thus, we also observed the changes of GAL and GAL mRNA in DRG neurons and the spinal cord. The results were as follows

为此本文拟在大鼠佐剂性关节炎模型上，结合行为学测定、用免疫组织化学、原位核酸分子杂交技术观察脊髓背角及DRG中CGRP、SP、α-CGRP mRNA、β-CGRPmRNA的动态变化及电针的影响，此外，用鞘内和外周注射CGRP的工具药探讨了CGRP在佐剂性关节炎发生发展中的可能作用；甘丙肽（Galanin，GAL）也是新近发现的一个神经肽，并与CGRP和SP共存于DRG及初级传入末梢中，在神经损伤模型中脊髓CGRP、SP减少，GAL则明显增加，显示GAL与CGRP和SP的作用可能不同，因此在佐剂性关节炎模型上也同时观察了GAL和GAL mRNA的变化，实验结果如下

During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.

项目期间（1997-2000）在番荔枝内酯方面从糖出发合成了五个天然产物和一批手性纯的类似物，它们对肠癌细胞有很高的活性和选择性，并与构型有关；在唾液酸酶抑制剂方面发展了二类全新手性纯高碳糖的合成方法－杂原子D－A反应或丙炔基不对称加成为关键的反应；抗白血病海洋天然产物群柱虫内酯方面研究了由糖出发和自由基环化反应的合成方法；对PKC 起抑制作用的鞘氨醇方面也开创了新的合成途径－由糖出发并以SN2'反应为关键反应。

The "twig" is a stick insect, a magnificent specimen of the Phasmatodea clan, its outer sheath a persuasive rendering of striated bark, its tubular body and head punctuated by fake axillary buds and leaf scars—the little knobs and notches that make a twig look twiggy.

那"细枝"是一只竹节虫，它极好地代表了竹节虫目这一神奇的种群，它的外鞘像极了皱巴巴的树皮，以假乱真的花苞和叶痕点缀在它管状的身体和头部——这些细小的凸起和凹陷让这根"细枝"看起来更像是很多细枝拼接起来的。

In a recess was a kind of divan, surmounted with a stand of Arabian swords in silver scabbards, and the handles resplendent with gems; from the ceiling hung a lamp of Venetian glass, of beautiful shape and color, while the feet rested on a Turkey carpet, in which they sunk to the instep; tapestry hung before the door by which Franz had entered, and also in front of another door, leading into a second apartment which seemed to be brilliantly illuminated.

Toxicity and repellent activity of several plant-based compounds on Blattella germanica were studied, results showed that rotenone, toosendanin and azadirachtin had stomach toxic effect on Blattella germanica, rotenone showed high stomach toxicity and all insects died after 8 hours, matrine also has deformative effect on Blattella germanica , matrine and toosendanin can affect oviposition of Blattella germanica; repellent activity of these botanicals was further studied, results showed that bering hydrochloridum, azadirachtin and sparteinehave had repellent activity against Blattella germanica, observation also showed that rotenone and bering hydrochloridum had high contact toxicity against Blattella germanica, the time of all insects knocked down were 8 and 48 hours.

选取了7种植物源化合物，测定了它们对德国小蠊的毒性和驱避性，结果表明，鱼藤酮、川楝素和印楝素对德国小蠊具有不同程度的胃毒作用，其中鱼藤酮乙酸乙酯溶液作用较强，8小时死亡率已达100％，川楝素和印楝素对德国小蠊也表现出一定的毒杀作用，观察还发现印楝素和苦参碱对德国小蠊的发育有致畸作用，苦参碱和川楝素影响其卵鞘形成；进一步对这几种化合物的驱避性进行研究，结果表明盐酸黄连素、鱼藤酮乳油和印楝素乳油对德国小蠊有不同程度的驱避作用，其驱避率分别为96.7％、51.3％和50.1％，另外观察到鱼藤酮乙酸乙酯溶液和盐酸黄连素对德国小蠊具有较强的触杀活性，供试虫全部被击倒的时间分别为8小时和48小时。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L 2, 4-D 2.5 mg/L, and 300 mg/L CH 0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus.

结果对仙茅叶片的愈伤诱导，黑暗的效果好于光照；在所试验的培养基成分中，适宜的激素配比是2.0mg/L2，4-D或6-BA1.5mg/L 2，4-D2.5mg/L，并且附加300mg/L水解酪蛋白和0.2%活性炭，对于仙茅叶片的离体成苗较好；培养后，愈伤组织主要由叶片的中脉产生，位于中脉上表皮内侧的薄壁细胞首先启动分裂，随后维管束鞘薄壁细胞及其外侧的叶肉细胞也启动分裂，参与愈伤组织的形成。
