E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

WO3, an interlayer compound prepared by J. W. Johnson (1981) using yellow tungstic oxide hydrate. Suspension of white powdery tungstic acid in anhydrous pyridine yields on standing for 2 wk whiteHW4O13.3H2O. IR and DTA studies revealed the connection between that pyridine polytungstate and white powdery tungstic acid (microcryst.), whose composition may thereby be assigned as H2W4O13.nH2O.

WO3。粉状白钨酸在无水吡啶中放置两周后可得到另一种化学式为(C5H5NH)HW4O13.3H2O的吡啶化合物，经IR和DTA研究可初步说明该化合物与粉状白钨酸之间的联系，并因此推测白钨酸的组成可能为H2W4O13.nH2O。

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。

It is suggested that the algae symbiot can affect host organellar function,quantity and location, stimulate the food uptake and digestive activity, restrain the functional activity of the organelle, change the gene expression and cause the change of genome structiure in the P. bursaria-chlorellae system.

The soluble protein content decreased during embryonic development. Vitellin was a main component of soluble proteins. Besides, there were other soluble protein subunits such as 243 ku, 181 ku, 67 ku, 54 ku and 31 ku proteins.

可溶蛋白的含量在胚胎发育过程中逐渐降低；在成熟卵细胞和胚胎期，可溶蛋白在组成上以89ku和100ku的卵黄磷蛋白(Vitellin， Vn)为主，同时还存在243ku、181ku、67ku、54ku和31ku等其他一些蛋白亚基。40ku蛋白亚基仅出现在成熟卵细胞中，推测可能参与执行了特定的生殖功能。

In details, the strongest inhabitation to the shoot growth was observed when neutral soluble fractionates were supplied. The shoot biomass with neutral soluble fractionates added was decreased by 10.52% over the blank control, resulting in obvious increase of root: shoot ratio. It suggests that the root exudates would be self-poisonous. Besides, both acid and alkaline soluble fractionates exhibited the trend to increase the stem height and it is necessary to exploit the reasons.

在培养液中，分别加入分组的烤烟根系分泌物，均显著降低根系对NO_3~-、H_2PO_4~-、K~+离子的吸收和根系活力，推测根系分泌物中产生抑制作用的物质可作用在相当宽的pH范围；其中，碱溶性组分对H_2PO_4~-、酸溶性组分对K~+、中性组分对NO_3的吸收和根系活力的抑制作用较强，推测在烤烟根系分泌物中，可能存在多种抑制烤烟生K和养分吸收的化学物质；另外，抑制作用随着根系分泌物浓度的增加而增强。

These data suggest that the terminal hairpin structure and ITRs of PfDNV play a key role in the rescue and gene correction process: sequence at the junction of the terminal palindrome of PfDNV genome and the pUC119 can form typical Holliday structure, it can be cutted by the special endonuclease, then the exposed 3'hairpin structure serving for a self-primer to initiate viral DNA replication; and the intact extremity acting as a template to repair another altered end within inverted terminal repeats.

说明存在着一种拯救和基因修复机制，推测与PfDNV基因组末端结构（Hairpin、ITR）有密切关系：PfDNV基因组与pUC119质粒连接处可形成Holliday结构而被识别该结构的核酸内切酶所切割，游离下的基因组3'发夹结构作为引物起始复制，然后被置换链的完整的5'ITR作为模板修复部分缺失的另一端ITR，推测这个过程需要病毒NS蛋白以及细胞因子的参与。

The thoracic duct endothelia in vitro could remain their biological properties, and could be made a tool for studing their functions and cancer metastasis mechanism by lymphatics. The positive expression of VEGF-C in cancer cells was correlated with cancer development, it seem to be that VEGF-C induce lymphoangiogenesis through its receptor Flt-4. The Flt-4 expression of lymphatics in cancer tissues was assosiated with cancer development, it is considered that there are new lymphatics in cancer tissues.
