查询词典 denervation

Methods A model of gastrocnemius muscle denervation at the right lower limb was established in 48 rats.

目的研究蛋白酶体亚基RC2在失神经骨骼肌中的变化规律及其意义。

However, the effect of denervation on the changes of titin and nebulin is unclear.

然而，截断神经引发肌肉萎缩的效应对肌肉内titin与nebulin的影响仍不清楚。

Both of them were comparable to each other in denervation potential.

两者肌电图失神经电位的变化则相似。

Denervation was achieved by multiple lesions at each level in an effort to provide effective denervation.

通过每个节段的多重损伤达到有效的去神经效果。

In the four placebo-controlled studies evaluating radiofrequency denervation outcomes in patients with "confirmed"l-z joint pain, the only study that screened patients with MBB demonstrated positive outcomes,157versus only one of three that used diagnostic intraarticularin jections.158–160 Ultrasound-guided medial branchand intraarticular blocks have also been demonstrated to provide comparable accuracy to fluoroscopically guided injections, although they may be less likely to detect low-volume intravascular uptake and are less accurate in obese patients.161–164 Because MBB are technically easier to perform than intraarticular injections and involve anesthetization of the nerves to be lesioned, it seems more logical to use these blocks as a prognostic tool before radiofrequency denervation.

在四个设有安慰剂对照的对于&确诊&小关节疼痛的患者行射频神经消融后的结果的研究中，唯一一个用MBB筛选研究对象的实验表现出阳性结果，而其他3个用关节内注射筛选的实验中只有1个表现出阳性。超声介导下的内侧支关节囊内阻滞被证实较透视介导更精确，虽然其血管内吸收剂量较低且在肥胖的患者中精确性较差。由于MBB较之关节内注射技术上更简单，且能对受损神经进行麻醉，利用这种阻滞作为神经射频消融前的诊断方法较为合理。

The proliferation of thyroarytenoid muscle and lateral cricoarytenoid muscle cell of dog remained at high level in 5 months after denervation and then slowed down and atrophy of muscles occurred 6 months after denervation.

甲杓肌及环杓侧肌失神经支配后5个月内保持高增殖水平，以后均降低，失神经支配6个月后肌萎缩开始明显。

Result :There was no significant difference between sexes,ages and sides.The fibrillation potential amplitude was maximum at 3 to 4 months after denervation of the posterior cricoarytenoid muscle or at 5 to 6 months after denervation of the thyroarytenoid muscle and still remained at certain level for years in some patients.Significant difference was showed in complete and incomplete nerve injuries groups,but changes of amplitude with time in incomplete nerve injuries group were small.

结果：不同性别、年龄及不同侧的纤颤电位波幅间的差异无显著性，失神经环杓后肌纤颤电位波幅均值在病程2～＜4个月时最高，而失神经甲杓肌纤颤电位波幅均值在病程4～＜6个月时最高，相当一部分患者的纤颤电位波幅晚期仍维持一定水平，并且神经完全损伤者和不完全损伤者各时间纤颤电位波幅均有显著性差异，而神经不完全损伤者各时间幅度变化小。

The morphologic change of muscle fibers: At the early stage of denervation, the area of cross sections decreased, some muscle fibers turned into angular fibers, nuclei congregated around the center of the fibers. After 8 weeks of denervation, atrophic and hypertrophic fibers coexist. Collagen increases under the endomysium and between the fibers.

肌纤维的组织形态学变化：面部肌肉失神经支配早期，肌纤维的横截面面积变小，出现角状纤维，肌细胞核聚集，细胞核从肌纤维边缘移至肌纤维中央附近；失神经支配后期，肿胀与萎缩的肌纤维并存，肿胀的肌纤维的横截面成倍大于正常的肌纤维，而萎缩的肌纤维的横截面则成倍小于正常的肌纤维；有大量的角纤维存在，肌纤维之间有较多的结缔组织增生。

This survival time was not significantly altered by bilateral denervation of cervical vagi (the major sensory system for detecting changes in pulmonary conditions), by bilateral denervation of peripheral arterial chemoreceptors (the major sensory system for detecting changes in arterial blood gases and pH), by pretreatment with dimethylthiourea, or by pretreatment with milrinone (a phosphodiesterase Ⅲ inhibitor that may avoid respiratory muscle fatigue).

而截断双侧颈部迷走神经（负责侦测肺内部情况的最主要感觉神经）、摘除双侧的周边化学接受器（负责侦测动脉血液气体及酸碱值的最主要化学接受器）、或投予Milrinone（一种phosphodiesteraseⅢ抑制剂，藉抑制cAMP被分解，以增加细胞内cAMP的量，可以使疲乏的呼吸肌内再增加收缩力）、Dimethylthiourea等药物的动物，都无法延长其存活时间。

When the effect ofNTP was examined after depletion of monoamines in the spinalcord by intrathecal neurotoxins, the antiallodynic and antihyperalgesiceffects were still observed after serotonergic denervation,but not after noradrenergic denervation.

鞘内给予神经毒素耗竭脊髓单胺递质后检查 NTP 的作用时，去除5羟色胺能神经支配后 NTP 的抗触觉性痛感和抗痛觉过敏作用仍然存在，但是去除去甲肾上腺素能神经支配后则消失。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
