It is a braided packing made of Kevlar yarns impregnated with P.T.F.E.dispersion and treated with lubricant,This packing can bear hither-pressure applications than other typees of braided packings ,Due to its steel-lide strength,this yarn can be employed separately or as back-up rings with other types of packing.

TW-203芳纶纤维盘根：它是同Kevlar纤维经浸渍四氟乙烯乳液及用润滑剂，处理再编织而的盘根，这种盘根比其它各种编织盘根能承担更高的介质压力，由于这种线像钢丝一样强，它可和其它种类盘根分隔安装或作为端面环。

METHODS: Forty extracted teeth with single straight canals and completed foramina were selected.

选择根尖孔发育完成的单根管离体牙40个，在生理盐水琼脂模型上，分别在根管内灌注25g/L次氯酸钠液、生理盐水、170g/LEDTA、30mL/L过氧化氢液和蒸馏水，在根管干燥条件下，用Root ZX测量牙齿操作长度，分析根管内容物对Root ZX测量值的影响。

The results showed as:(1)Gegen decreases fasting insulin and insulin resistance index and increases insulin sensitive index of rats of insulin resistance induced by dexamethasone significantly;(2)Gegen can improve glucose tolerance of rats of insulin resistance but not to alloxan indued diabetes mice;(3)Gegen increases glucose intake of 3T3-L1 adipocytes and improves the insulin resistance of 3T3-L1 adipocytes induced by dexamethasone significantly;(4)Gegen can activate peroxisome proliferator- activated receptor gamma, make it bind to PPAR response elements;(5)Gegen can up-regulate mRNA expression of PPAR v ,aP2 and adiponectin.

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

Ss group was by prepared by k-files with step-back technique. all canals were obturated using lateral condensation technique.

将245颗具弯曲根管需行根管治疗的磨牙随机分为两组，he组用hero642镍钛锉及冠根向深入法预备根管，ss组用k锉及逐步后退技术预备根管。

Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果：诱导出了天山大黄发根，并建立了发根离体培养系；从发根中检测到甘露碱、农杆碱的存在；定量分析发现，天山大黄发根中含有多种蒽醌类成分，其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

The incidence of large quantity of overfilling was 23.08% in group 1 and 11.58% in group 2, and the difference was statistically significant.

牙齿工作长度的精确测量是根管治疗术成功的重要环节，没有准确的根管工作长度就无法保证根管充填中严密的根管封闭，而根管治疗术的成功与否，直接影响到患牙能否保存及功能恢复状况。

Key words］root canal apex locator; periapical diseases; dental pulp cavity; working length; aged

1.2 方法常规开髓揭顶，清理根管，将root zx根管测量仪电极置于被测牙的对侧口角处，探测端接10号k型锉，缓慢进入根管，当测量仪显示到达根尖孔时，用制动片记录其长度，直接摄x线片证实k型锉所到达的位置，确定根管测量仪的准确性。

This trend was obvious for 5-year-old plantation. The biomasses of living and dead fine roots at 0~10cm accounted for 51.9% and 53.3% of the totals, respectively. The 84.6% of living and 82.8% of dead fine roots concentrated at the depth of 0~30cm.

在0~10cm土层中的活、死细根生物量分别占全部活细根生物量的51.9%和死细根生物量的53.3%，活细根生物量的84.6%和死细根生物量的82.8%分布在0~30cm的土层中。

Compact obturation is an important factor for root canal therapy, focusing on reducing the channel of entering root system through mouth and peripheral apical tissue and blocking excitant which is not completely removed during debriding and repairing root canal.

致密的封填是根管治疗成功的关键之一，其主要目的是为减少经由口腔或根尖周围组织渗透进入根管系统的信道，以及将根管清创、修形过程中无法完全移除的刺激物封闭于根管系统内。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
