查询词典 sciatic

The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index.

OT is involved in the modulation of the transmision of nociceptive information in the spinal cord of rats with sciatic nerve ligation Intrathecal administration of OT induced a significant analgesic effect during 1 to 10 day after sciatic nerve ligation and a significant hyperalgesic effect from 11 day after sciatic nerve ligation .

Methods Seventy-eight adult female PVGrats were divided into experimental group (n=60) and control group (n=18), intraneural injection technique was used to supply three kinds of NO donors with different half-life(DETA NONOate, DPTANONOate and Spermine NONOate) or saline into the rat sciatic nerve subperineurally under light microscope. At the 1th,2th,3th,7th,and 14th day of duration after sciatic nerve injection, a segment of injected sciatic nerve was taken out and embedded it in TAAB resin after tissue processing. Then it was cut into thin layers (1μm) and the histological changes were observed under high power microscope, meantime the number of degenerated axons were counted.

选择78只雌性PVG大鼠，分为实验组和对照组，以在体神经内微注射实验方法，将三种半衰期不同的NO供体(DETA NONOate，DPTA NONOate和Spermine NONOate)及生理盐水分别注入大鼠左侧坐骨神经的神经束膜下，于注射后的不同时间(1天、2天、3天、7天和14天)取出注射部位的坐骨神经，经组织学处理后做成树脂包埋块，以超薄切片机切片，然后在高倍显微镜下观察并计数神经横断面的变性轴突数目。

Three animals randomly selected from three groups were killed on Day 0 to determine the baseline of PLA2 activity within unmanipulated rat sciatic nerve; other 39 animals underwent operation for model-making of acute sciatic （Maves-modified Bennet-Xie model） on right sciatic nerves, while Sham operations were performed on left sciatic nerves.

第0天，每组随机抽取1只共3只大鼠处死，测量双侧坐骨神经节段磷脂酶A2活性为基线，其余39只大鼠右侧坐骨神经制作急性坐骨神经痛模型（Maves改良的Bennet-Xie模型），对侧行Sham手术；第7天，每组随机抽取3只处死，测量治疗前模型和Sham坐骨神经节段的磷脂酶A2的活性；第14天，剩余大鼠处死后测量各组模型和Sham坐骨神经节段的磷脂酶A2的活性。

There were soluble trophic molecules with relative molecular weight larger than 30 000 for survival and neurite growth of FMN cultures in media with SC-CMCs derived from facial and sciatic nerves of neonatal rats and with SC-CMCs derived from Wallerian degenerating facial and sciatic nerves of adult rats. It might be reasonable to choose SC from sciatic nerves of rats on account of the findings from SC cultures on facial motoneurons.

面神经和坐骨神经SC-CMC中含有促FMN存活、生长的蛋白或多肽，相对分子质量大于30 000，其活性作用与使用的蛋白浓度有关；在研究SC分泌物对FMN营养活性作用时，可考虑选择坐骨神经SC。

Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch. The segment of sciatic trunk which ran between the sacrum and ilium was stable and feasible for localization according to the related bony structures in CT scanning, so it was selected as irradiation target. After high dose of stereotactic radiation, the degeneration and necrosis in nerve fibers could be observed under microscope.
