    • PURPOSE: Salmonella which improves gene expression is provided to maximize treatment effect by highly expressing a foreign gene from a Salmonella strain for therapy even if a small amount of L-arabinose is administered. CONSTITUTION: An attenuated Salmonella sp. strain has inactivated intrinsic ppGpp producing genes and ara operon. The ppGpp producing gene is relA and spoT. A recombinant attenuated Salmonella sp. strain is prepared by transducing a gene construct containing a polynucleotide encoding a foreign gene which is operatively linked to ara promoter or a nucleic acid molecule for suppressing gene expression. A drug delivery system for targeting cancer or infarction contains the attenuated Salmonella sp. strain or the recombinant attenuated Salmonella sp. strain and a drug delivered to a cancer or infarction tissue by the strains. [Reference numerals] (AA) Concentration of L-arabinose (%)
    • 目的:提供改善基因表达的沙门氏菌,以便即使施用少量的L-阿拉伯糖,也可以通过高度表达来自沙门氏菌属菌株的外源基因来治疗,以最大化治疗效果。 构成:减毒沙门氏菌 菌株已经灭活了内生的ppGpp产生基因和ara操纵子。 ppGpp产生基因是relA和spoT。 重组减毒沙门氏菌 通过转导含有编码与ara启动子有用的外源基因的多核苷酸的基因构建体或用于抑制基因表达的核酸分子来制备菌株。 用于靶向癌症或梗死的药物递送系统包含减毒的沙门氏菌属。 菌株或重组减毒沙门氏菌 菌株和通过菌株递送至癌症或梗塞组织的药物。 (AA)L-阿拉伯糖浓度(%)

    • PURPOSE: A selective infart-tissue-targeting bacteria and use thereof are provided to improve affinity and specificity to infarction myocardium or infarction brain, thereby reducing transfection other than heart. CONSTITUTION: A drug delivery system for infarcted tissues includes obligatory anaerobic or facultative anaerobic bacteria. The bactia are Salmonella, Clostridium, Bifidobacterium, E. coli, Yersinia enterocohtica, Listeria monocytogenies, Mycoplasma hominis, or Streptococcus. The bacteria are mutants which are deficient in ppGpp synthesis function. The bacteria comprise ppGpp for ppGpp synthesis, inactivated relA gene which codes synthetase or spoT gene. The infarction indicates either myocardial infarction or cerebral infarction. A pharmaceutical composition for treating the infarction comprises effective dose of drug delivery system and a pharmaceutically allowed carrier. The drug carrier includes the infarction treatment drug.
    • 目的:提供选择性的infart组织靶向细菌及其用途,以改善对梗塞心肌或梗死脑的亲和力和特异性,从而减少心脏以外的转染。 构成:用于梗塞组织的药物递送系统包括必需的厌氧或兼性厌氧细菌。 细菌是沙门氏菌属,梭菌属,双歧杆菌属,大肠杆菌,肠易耶一肠炎,单核细胞增多性李斯特菌,人支原体或链球菌。 细菌是缺乏ppGpp合成功能的突变体。 细菌包含ppGpp用于ppGpp合成,灭活的relA基因编码合成酶或spoT基因。 梗死表示心肌梗塞或脑梗塞。 用于治疗梗死的药物组合物包括有效剂量的药物递送系统和药学上允许的载体。 药物载体包括梗死治疗药物。

    • PURPOSE: An optical molecular imaging device for simultaneously monitoring the fluorescence imaging of small animal is provided to reduce the manipulation steps of a user by simultaneously taking the two images of one object. CONSTITUTION: An optical molecular imaging device for simultaneously monitoring the fluorescence imaging of small animal comprises a housing(110), a movable stage(120), an irradiating unit(130), and a photographic unit(140). The housing forms the space shut tightly. The movable stage comprises a table(121), in which the subject locates, and is installed in the lower part of the housing. The irradiating unit radiates the light for taking a photograph of the subject.
    • 目的:提供用于同时监测小动物荧光成像的光学分子成像装置,以通过同时拍摄一个对象的两个图像来减少用户的操纵步骤。 构成:用于同时监测小动物的荧光成像的光学分子成像装置包括壳体(110),可移动台(120),照射单元(130)和照相单元(140)。 外壳形成紧密的空间。 可移动台包括被检体位于其中并安装在壳体下部的工作台(121)。 照射单元照射用于拍摄被摄体的照片的光。
