阻滞

We may well explain why ricin-induced apoptosis showed no typical DNA ladder. The presence of laddering in DNA gels implies an apoptosis process, but its absence does not rule out the apoptosis. The ricin 0.05μmol〓 had no effect on the 〓 phase of cell cycle, but induced 〓 arrest. The ricin may affect the balance of synthesis and destruction of proteins that controlling the cell cycle.

检测到DNA梯度表明细胞发生了细胞凋亡，未检测到DNA梯度不能否认凋亡的存在。0.05μmol.L〓的蓖麻毒素对HeLa细胞周期的G〓/G〓期无影响，而诱导了G〓/M期阻滞，蓖麻毒素可能引起一些控制细胞周期蛋白的合成与降解发生紊乱。

Intraoperative glucose and insulin infusion cannot prevent hypothermia in patients undergoing esophageal cancer surgery under combined general anesthesia with epidural block, however, it may reduce lipoclasis.

对于硬膜外阻滞复合全麻下行剖胸食管癌手术的患者，术中输注葡萄糖和胰岛素不能减轻术中深部体温下降，但是可能有抑制脂肪分解的作用。

Blockade was effective during the early (week 10) as well as late ( approximately week 90) phases of chronic infection even under conditions of severe lymphopenia.

这种阻滞在慢性感染——甚至是淋巴细胞严重减少的条件下——的早期（10周）和晚期（大约第90周）是很有效的。

BACKGROUND: Posterior tibial nerve block has traditionallybeen performed in the para-medial malleolar area without nervestimulator guidance.

背景：在没有神经刺激器引导的情况下，胫后神经阻滞传统是在旁正中踝区域完成的。

In this study we compared the frequency of successful PTN blockat the traditional distal site (2 cm above the medial malleolus)with and without NS guidance.

在这项研究中，作者比较了使用和不使用 NS 向导的情况下，在传统的远中心端（内踝2cm ）成实施 PTN 阻滞的频率。

RESULTS: The fracture of tibial plateau usually induces the malunion of fracture, growth retardation of epiphyses and ultimately shape valgus deformity of knee joint.

结果：在创伤中，胫骨平台骨折常常造成骨折的畸形愈合，骨骺的生长阻滞，最终形成膝关节的外翻畸形。

Furthermore, establishing core companies, which replace the product wholesale marler, is regarded as an effective countermeasure to this problem in this paper. At last, two patterns of the product supply chain based on core companies are given.

同时指出培育农产品供应链核心企业，并取代农产品批发市场发挥核心作用，是解决供应链信息阻滞的有效途径之一，最后探讨了围绕核心企业来建立农产品供应链的两种运作模式。

Other cases of congenital hydrocephalus involve a narrowed mesencephalic aqueduct with obstruction to CSF flow.

其他的原发性水脑症也有可能因为中脑导水管的阻滞导致脑脊液流动受阻。

p21WAF1 may be pivotal in the hypertrophy and arrest in the G1 phase of mesothelial cells induced by high concentrated glucose.

p21WAF1可能在高糖作用下间皮细胞的肥大及G1期阻滞中起重要的调节作用。

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

在扫描电子显微镜下观察，在微球内外未发现尼群地平的完整结晶，X-射线粉末衍射和差示扫描量热试验结果也显示，尼群地平已经被高度分散在微球中；微球的释药速度可通过调整处方中固体分散体载体和阻滞剂的比例控制；制备温度和搅拌速度对微球的质量影响较大；溶出仪的搅拌速度，释放介质的浓度和pH对微球的释放有较大的影响；制备过程中的冷却速度和冷却时间对微球的释放行为影响不很明显；方程拟合的结果表明缓释微球的释药行为符合扩散机制；测定三批微球样品的包封率均在96.8％以上，表明该法适合于制备难溶性药物的缓释微球。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
