吸烟不仅对健康有害，而且增加空气污染程度。香烟雾含有多种有害物质：不仅有致癌化学物质、有某种能阻止氧气进入血液的气体，还有引起血压增高、心速加快的被称为尼古丁的物质。

OBJECTIVEO To study the changing of bulbus medullae SP and 5-HT when rats were disposed by different medicine that can make people vomit and provide experimental basis for detecting the pathological mechanism of reverse ascending of Stomach—Qi.

目的：通过对大鼠给与不同致呕吐物质的刺激，研究大鼠在接受不同呕吐物质刺激后其延髓组织P物质及5-羟色胺(5-HT)的变化，为中医学&呕吐&证发生的病理病机&胃气上逆&的理论，提供分子生物学依据。

RESULTS Ouabain-like immunoreactivities were observed abundantly in the inner zone of adrenal cortex, known as the zone reticularis of SD rats and Macaca mulattas; weakly in the posterior pituitary of SD rats, but nothing in the hypothalamus.

结果 在大鼠和恒河猴的肾上腺皮质内侧网状带细胞中可以观察到丰富的哇巴因免疫反应阳性物质，垂体后叶有较弱的哇巴因免疫反应阳性物质，而下丘脑并未发现有哇巴因免疫反应物质存在。

Comparative study on two levels of population and modules of mutualspecies in the two stations demonstrates that feature index tend to diminish suchas height,tussock amplitude,size,number,density and dry weight;and thegrowth analysis index incline to increase such as RGR、ULA、chlorophyllcontent and effectiveness of plant multi-leaves of the populations and DULA、DUMR、DAGA and DRGRa of the modules;and the dynamic curves of thepopulations and the modules also tend to steadily increase along with thetemperature ascending,heat accumulation and combination between water andheat in moderate-temperature steppe from fierce fluctuation alongside naturalprecipitation in warm-temperature steppe,illustrating that the transformabletendency from increasing the numbers of tussocks and tillers in order to expandthe resource range to seize in warm-temperature steppe to steadily improve drymatter production function of the populations and the modules in moderate-temperature steppe.

两个不同热量型研究站点共有种种群与构件两个水平的比较研究表明：随纬度增加和气温降低，种群与构件高度、丛幅、大小、数量、密度和干重等特征指标趋于降低和减少，而种群RGR、ULA、叶绿素含量和植物多叶性与构件DULA、DUMR、DRGR和DRGRa等生长指标则趋于增加，种群与构件的生长动态曲线也从随天然降水而剧烈波动趋向于随气温升高、热量积累和水热配置状况而稳定增长，说明各共有种从暖温型草原区增加植物种群与构件的大小和数量以扩充资源利用范围向中温型草原稳定地提高种群与构件的干物质生产性能的方面转变的趋势；同时，物质与能量的分配也从较多地投资于繁殖器官产生大量后代以适应未来降水的不可预期变化趋向于同化系统的构建和干物质生产效能的提高以抵御低温和干旱对物种生存的威胁，充分显示出不同温度条件及其水热组合对植物种群形态结构和生长繁育模式的显著影响及其响应特征。

Chemistry material is the matter of chemistry movement , also the matter object of chemistry science research.

摘 要：化学物质是化学运动的物质承担者，也是化学科学研究的物质客体。

In this article, the effect of different water pH (pH 5, 6, 7, 8, 9)on the secretion of nacre of freshwater pearl mussel Hyriopsis cumingii were studied with histochemical methods and transmission electron microscopy.

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。

Human self-production is an important aspect in the material productions of human practics and a material foundation of all human practics (material production, spirit production and discourse production).

人的自身生产是人类实践的物质生产之中的一个重要方面，是人类一切实践（物质生产，精神生产，话语生产）的物质基础。
