The results of in situ hybridization showed that the gene of Mdde was expressed mainly in epidermis of the body wall and fat bodies, and no expression signal was detected in tracheae, intestine and musculature. The gene of Mdde in epidermis expressed both in challenged larva and no-challenged larva, whereas the gene of mdde in fat body expressed only in challenged larva.

原位杂交的结果表明：Mdde基因在家蝇幼虫体内主要表达于表皮和脂肪体，在气管、肠和肌肉组织中没有检测到Mdde基因的表达；表皮中Mdde基因在微生物刺激前后均有表达，而脂肪体中Mdde基因经微生物刺激后才表达，刺激前不表达。

ABSTRACT Aim and Methods: Using fast cyclic voltammetry and carbon fibre mi croelectrode, we monitored dopamine release from caudate putamen ,nucleus accumbens and central amygdaloid nucleus of normal rats in v ivo, in order to find out the suitable parameters to evoke DA release of certa in area. DA release was evoked by electrical stimulation of medial forebrain bundl e or ventral tegmental area.

目的和方法：采用快速周期伏安法在体研究电刺激内侧前脑束或腹侧背盖区诱发的纹状体、伏核或中央杏仁核多巴胺释放的特点，探索电刺激诱发不同核团DA释放的适宜刺激参数。

Before transfected with AT1, neither AngⅡ nor stretch increased the activation of ERKs. After transfected with AT1, pretreatment with AngⅡ for 8 min or stretch for 10 min activated ERKs obviously.

COS7细胞转染AT1受体以前， AngⅡ和牵张刺激都不能引起细胞内ERKs磷酸化升高；而转染野生型AT1后，AngⅡ和牵张刺激引起细胞内ERKs磷酸化明显升高，各突变体中，Q257A和C289A转染细胞后细胞对牵张刺激的反应受到明显抑制，提示AT1的牵张感受位点在Q257A和C289A。

In exceptional circumstances, a dream to the delicious food, will stimulate saliva secretion, saliva secretion increased, it will lead to drooling; improper sleeping positions sometimes lead to the phenomenon of flow of saliva; Some people sleep regularly teeth and stimulate the brain nerve center, to promote saliva secretion, so that flow of saliva; some people love spicy food thing, or, tobacco, liquor, so that night, dry mouth, increased saliva secretion; sleep, mouth breathing tends to dry mouth, thus contributing to an increase in saliva secretion ; In addition, some diseases, such as infectious stomatitis, toothache, mercury, potassium iodide poisoning, but also can stimulate an increase in saliva secretion, causing sleep drool.

是对美食的梦想，会刺激唾液分泌，唾液分泌增加，会导致流口水，有时睡觉姿势不当导致的唾液流现象，有些人睡眠定期牙齿和刺激大脑神经中枢，促进唾液分泌，使唾液流动，有些人喜欢吃辣的东西，或者，烟，酒，所以这天晚上，口干，唾液分泌增加，睡眠，口呼吸往往口干，从而促进在唾液分泌增加，此外，如传染性口腔炎，牙痛，汞，碘化钾中毒的一些疾病，而且还可以刺激唾液分泌增加，造成睡眠流口水。

With objective detection threshold timeas the prime exposure time and figues (Ara-bic figures) and numerals in Chinese andGermans as stimili,we compared the primingeffects of Chinese and German under patter-ned masking.

本文采用客观觉察阈值作为启动刺激呈现时间、以数字和数词(以中、德两种文字写出的数词)为刺激比较研究了在掩蔽刺激条件下中国与德国被试的启动效应。

The needle would stop rolling to maintain the friction effect between the needle and tested tissue when this friction moment come to the driving moment of the friction coupler.

二、在驱动电机和刺激针之间设计一个摩擦耦合器，当刺激针和组织之间的摩擦力矩达到摩擦耦合器的驱动力矩后，刺激针就会停止转动并能保持住对组织的摩擦。

METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively.

用Ficoll-Hypaque梯度离心法分离出正常成人抗凝外周血单个核细胞和血浆，将PBMC置于含或不含有自身血浆环境中，并在植物血凝素(PHA ，2 0mg L)的刺激下进行培养，培养 2 4、48、72h后收获细胞，分别用双色免疫荧光标记，以流式细胞术对CD4+ T细胞表达表面分子CCR3、CCR5进行分析。结果：CD4+ T细胞受自身血浆和PHA刺激后向Th1 Th2两个方向极化，2 4、48、72h后极化率分别达到(13 2 8± 1 5 9)%(12 70± 1 6 5 )%、(17 19± 1 0 3)%(17 5 0± 1 30 )%、(19 49± 2 87)%(18 5 8± 1 49)%；而只有PHA刺激的极化率很低，两组有显著性差异(P 0 1)；Th1∶Th2之比约等于 1。

When the baby when a normal birth, the baby's head will be squeezed, the pressure of the baby's birth canal is a good stimulation of the sensory organs, which stimulate the conduction brain, right brain circulation of blood to enhance stimulation of the brain's respiratory center to provide more material basis of the baby's hearing and so on is a very good training, while caesarean section babies have lost the opportunity to exercise.

当宝宝正常分娩的时候，宝宝的头部会受到挤压，产道的压迫对宝宝的感觉器官是一种良性刺激，这种刺激传导大脑，对脑部血管循环加强刺激，为脑部的呼吸中枢提供更多的物质基础，对宝宝的听觉等是一次非常好的训练，而剖腹产的宝宝则失去了这一锻炼机会。
