Mainly be applicable to and arrange tidy, the lightly mid-degree tooth body of quality integrity changes countenance, whole the tooth light degree arrive mid-degree fluorine spot tooth, whole the tooth light degree four wreaths plain tooths, individual the tooth changes countenance, because the age increases the tooth color that the dentine change causes and delivers Huang and wants to become more white healthy buff tooth, heavy degree four wreaths plain tooth enamels sticks a noodles creation the bleach of front can make and whet in addition to of tooth quantity decrease, the effect is better.

主要适用於排列整齐、质地完整的轻中度牙体变色、全口牙齿轻度到中度氟斑牙、全口牙齿轻度四环素牙、个别牙齿变色、因年龄增长牙质改变引起的牙色发黄，想变得更白的健康浅黄色牙齿、重度四环素牙瓷贴面制作前的漂白可以使磨除的牙齿量减少，效果更佳。

Once was applicable to a small tooth, ex- tooth tooth cleft(the ≤ 2 mms), the whole the tooth light degree arrives to weigh a degree a fluorine spot tooth, whole light degree and mid-degree four wreaths plain toothses, whole tooth heavy degree four wreaths plain tooths match with bleach to also attain better effect, the tooth changes countenance separately, the tooth light degree arranges not and together and needs to change shape separately, and the external injury tooth breaks.

适用於过小牙齿，前牙牙齿间隙（≤2mm ），全口牙齿轻度到重度氟斑牙，全口轻度、中度四环素牙，全口牙齿重度四环素牙配合漂白也可以达到较好的效果，个别牙齿变色，个别牙齿轻度排列不齐，需要改变形状，外伤牙齿折断。

Pretiosum were continuously provided with tetracycline/30% honey water (1mg/ml、10mg/ml and 100mg/ml) for 10 generations only a few males and intersexes appeared in each generation, most of the progeny were still females.

而被1mg/ml、10mg/ml 和100mg/ml的四环素（四环素量：30℅的蜂蜜水）连续处理10代后，每代均出现了少量的雄蜂和雌雄嵌合体。

Objective To analyze the existing problems tetracycline products face and to propose solutions.

摘要目的分析四环素类药物面临的问题，探讨四环素类药物新发展的途径。

Is permanent, but now no longer has a tetracycline.

It is confirmed again that the tetracycline system is effective to regulate gene expression .

同时本实验也成功建立了在四环素调控系统下诱导的SV40Tag转基因肿瘤小鼠，再次证明了，四环素调控系统在基因表达调控的有效性与准确性。

Tetracycline showed a good regulation on the expression of P37 protein, which was not detectable without tetracycline induction.

四环素对其表达显示出明显的调控作用，不加四环素的细胞不表达P37蛋白。
