It was also studied the tissue distribution characteristics of harmine intravenous emulsion in mice.

采用反向透析技术测定了乳剂的体外释药性能，这种释放模型较好地摸拟了体内生物环境，用多个小透析囊巧妙地实现了药物分子与介质中其它成分的直接分离，使含量测定易于进行；实验结果表明，乳剂粒子内药物向介质的释放过程和释放出来的药物分子渗透进入囊的过程均为被动扩散机制，并且药物在乳剂中的相分配不同其体外释药速度，尤其是最初释药阶段的速度存在明显差异（P.05）。

As a result, we observe huge amount of calcium phosphates deposit inside the cells in our experiments, which is different from previous studies. Based on the results, we think that permineralization is the favored mechanism for calcium phosphates to mineralize on the structure inside the cells.

突破了只能在细胞外部沈积的研究结果，因此我们认为非生物性的渗透作用机制可能是当时瓮安生物磷酸矿化形成化石的主要原因。

Two methods including high performance gel permeation chromatography and gelatin nephelometry were used to test the stability of 916 by lysozyme and trypsin.

在稳定性研究方面，选择生物体液中存在的两种酶---溶菌酶和胰蛋白酶作为考察条件，采用高效凝胶渗透色谱法和明胶比浊法，分别考察不同指标，从分子量及分子骨架是否变化到有效基团是否脱落以确定916的稳定性。

The group's research interests include: regulation and molecular control of blood pigment function and functioning, adaptive physiology of sharks and rays, hormonal control of osmoregulation and the physiological and ecological changes in the evolution to life on land, and the evolution of blood function in the crustacean invasion of land etc.

Give birth to content and food engineering according to university of industry of project technology chief, Dalian courtyard dean Zhu Bei osmund professor introduction, this project developed microtherm vacuum to permeate first flavor to style of technology, stage warms up and cool antiseptic processing technique, in the treatment that uses at eating abalone product namely, solved original feed the difficult problem of technology of not easy pilot such as abalone product appearance, mouthfeel, aroma, color namely, built the manufacturing technology system that feeds abalone namely, to develop other ocean shellfish fed a product to lay good foundation namely; Use first from dissolve enzymatic with outside polysaccharide of abalone of extraction of method of source enzymatic compound, raised the recovery rate of polysaccharide greatly; Use enzymatic law and the method that Sevag law photograph combines, solved effectively take off the difficult problem of miscellaneous albumen in dividing abalone polysaccharide, raised polysaccharide purity, maintained polysaccharide active, the technical system of the preparation that built abalone polysaccharide, detached, rarefied, analysis, draw lessons from goodly to developed polysaccharide of other and marine animal to offer.

据项目技术负责人、大连工业大学生物与食品工程学院院长朱蓓薇教授介绍，该项目首次开发了低温真空渗透调味技术、阶段式升暖和冷却杀菌加工技术，并应用于即食鲍鱼产品的加工中，解决了原有即食鲍鱼产品外形、口感、香气、颜色等不易控制的技术难题，建立了即食鲍鱼的生产技术体系，为开发其他海洋贝类即食产品奠定了良好的基础；首次采用自溶酶与外源酶复合的方法提取鲍鱼多糖，大大提高了多糖的提取率；采用酶法与Sevag法相结合的方法，有效地解决了脱除鲍鱼多糖中杂蛋白的难题，提高了多糖纯度，并保持了多糖活性，建立起了鲍鱼多糖的制备、分离、纯化、分析的技术体系，为开发其他海洋动物多糖提供了良好的借鉴。

Detached undissolved mucus traps suspended particles, increasing its initial organic carbon and nitrogen content by three orders of magnitude within 2 h.

溶解的粘液被浮游细菌很快降解，也在抽吸作用下穿过可渗透的礁石沙子，后者起一种生物催化过滤系统的作用。

Their stark and cheerless surroundings penetrate their souls and yet, at another level, they are valedictory creatures straddling two ambivalent universes.
