日至时期的台南府城南门外地区，因为在日本政府的政令之下，开始大规模的迁葬，迁葬之因即为日本政府所实施的台南市都市计画，分为三个时期，萌芽期、开拓期、展开期，逐步的扩张台南市的都市范围，因此在取得土地的过程中，项城郊一代发展，台南府城南门外的墓葬区成为日至时期台南市南向发展的重心，经过坟墓迁移之后的土地，经过重新规划，行程教育、运动设施的专用地，日至时期台南府城南门外的墓葬景象，在透过日本政府的政治力量的迁葬之下，以及迁葬之后的建设，转变成学校与运动场，充满活力的区域。战争期间，因为战争需要，在台南府城南门外墓葬区的南侧建立台南军机场，因此在战争期间，台南府城南门外地区又带入军事的色彩，战后国民政府接收日本人撤退之后的所有建设，将空军后勤补给对进驻台南军机场，随之而来的眷属则占据日本人的宿舍，另外在新建多处的眷村，战后初期的眷村文化即进入台南府城南门外地区。

The inducible nitric oxide synthase is obviously expressed in speen of rats under the predator stress, suggesting important function for iNOS in speen physiology. However, the expression and subcellular localization for NOS in speen development and differentiation are largely unknown. In the present study, the changes in iNOS activity in spleen of rats under predator stress were studied to explore the role of iNOS in the decreased immunoactivity of the stressed rats. The changes in iNOS were observed with immunobistochemical method, and the contents of NOS and NO in spleen with biochemical method.

在捕食压力下，大鼠脾脏诱导型一氧化氮合酶明显表达，说明iNOS起到了重要的生理功能，然而，NOS的表达及在亚细胞水平的定位以及相应的差异变化等都很不明确，本试验采用捕食应激模型，利用免疫组织化学方法和生化测定，检测心理性应激对大鼠脾脏iNOS活性的影响及探讨这种影响与应激动物免疫力下降之间的关系。

As a result of changes in external conditions, vector oilysludge ensued in which the relative stress, shape, physical changes, sporal.

因外界条件变化，载体基材随之产生相对应力，而发生形态、物理，化学性质的变化。

The expression changes of ICAM-1 and p65 mRNA level were detected by reverse transcription-polymerase chain reaction and the expression of p65 protein in AR42J cell lines were detected with Stept Avidin-Biotin complex respectively, and the changes of amylase in culture medium with chromatometry.

逆转录－多聚酶链反应半定量法观察细胞间黏附分子(ICAM-1)和p65亚单位mRNA表达的变化；链酶亲和素－生物素－过氧化物酶复合物法检测p65蛋白在AR42J细胞中的表达；人工碘比色法观察培养液上清中淀粉酶的活性改变。

Non-stoma-related factors affected net photosynthetic rate changes under high-density conditions, while under low-density conditions stomatic factors affected net photosynthetic rate changes.

The study sample was composed of 40 female patients with maxillary excess or bimaxillary protrusion. The mean age of patient was 25.9. All patients had undergone the modified Wunderer technique for anterior subapical osteotomy. The postoperative follow-ups were all over 6 months. We studied the relationship between movement of anterior maxillary segment and soft tissue changes over nose and lip areas by the statistics in the hard tissue displacement and soft tissue changes 3 and 6 months postoperatively.

本研究收集以改良式Wunderer's前上颚根尖下截骨术矫治双颚前突或上颚生长过度的病例共40位，皆为女性，平均年龄25.9岁，术后追踪半年以上；分别研究术前与立即术后，立即术后与术后三个月，以及术前与术后六个月的硬组织方位改变，鼻唇区域软组织的方位改变，以及硬组织与软组织间方位改变的对应关系。

Stress reduces neurogenesis in the dentate gyrus subgranular zone, but it is unknown if stress-induced changes in neurogenesis contribute to individual vulnerability. Using a chronic social defeat stress model, we explored whether the susceptibility to stress-induced social avoidance was related to changes in SGZ proliferation and neurogenesis.

长期压力已知会引起一些精神疾病，可是尚不清楚一些人比另外一些人更容易产生这些症状的神经器官基矗Bmelia Eisch及其同事研究了大脑的海马区——对进修和记忆具有重要性的区域——并探索了神经器官形成对受压力影响严重的大脑功能的作用。

The transition from the systemic inflammatory response syndrome to seere sepsis and septic shock inoles a myriad of pathogenic changes, including circulatory abnormalities that result in global tissue hypoxia.1,2 These pathogenic changes hae been the therapeutic target of preious outcome studies.12 Although this transition occurs oer time, both out of the hospital and in the hospital, in outcome studies interentions hae usually been initiated after admission to the intensie care unit.12 In studies of goal-directed hemodynamic optimization, in particular, there was no benefit in terms of outcome with respect to normal and supranormal hemodynamic end points, as well as those guided by mixed enous oxygen saturation.9,13 In contrast, een though we enrolled patients with lower central enous oxygen saturation and lower central enous pressure than those studied by Gattinoni et al.9 and with a higher lactate concentration than those studied by Hayes et al.,13 we found significant benefits with respect to outcome when goal-directed therapy was applied at an earlier stage of disease.

从全身炎症反应综合征转为严重脓毒症和脓毒性休克牵涉大量发病的变化，包括导致全身性缺氧的循环紊乱。这些发病的变化成为先前结果研究的治疗学目标。尽管这些转变随着时间的流失而逐渐出现，既可以在院外，也可在院内，在结果研究中，干预措施往往在进入ICU之后才启动。特别的，在那些目标导向血流动力学最优化研究中，依照结果，那些以正常或超正常血流动力学为终点的措施未能显示出益处，以混合静脉血氧饱和度为导向的研究同样如此。
