Objective to evaluate the functional recovery of acute spinal cord injuried rats treated with exogenous wnt-3a signal protein administration and to explore its mechanism.methods moderate spinal cord contusion injury was made in 40 adult sprague dawley rats at t10.twenty rats served as contusion controls(group 1).twenty rats were treated with wnt-3a for three days after injury (group 2).the functional recovery of the rats was observed through basso,beattie,bresnahan open field locomotor score.rats were killed at 14 or 28 days after injury,then spinal cords were removed for histopathological examinations,and the expression of the bromodeoxyuridine plus neural cell markers was stained with immunohistochemical method.results rats of two groups receiving a contusive injury recovered substantial function within 1 week.by 28 days,rats in groups 2 scored 7.0 points better on the bbb scores than rats in group 1 group 2=16.94,after 28 days vs.

目的 研究外源性wnt-3a信号蛋白对脊髓损伤的修复作用，并探讨其作用机制。方法取40只成年雌性sd大鼠在t10节段制备适度脊髓挫伤模型。随机从中取20只为损伤对照组(group 1)，另外20只为损伤治疗组(group 2)。脊髓损伤3天后用wnt-3a蛋白治疗。这些大鼠的功能恢复通过basso、beattie、bresnahan开放视野运动评分来观察。这些大鼠分批在损伤后14天或28天被处死，取出损伤节段脊髓用来组织病理学检查，同时用5-溴脱氧尿嘧啶核苷和神经细胞标记物进行免疫组化染色。结果两组大鼠在伤后一周运动功能有明显的恢复。不过，到损伤后28天，我们观察发现，损伤治疗组中的大鼠bbb评分比损伤对照组中的评分高出7.0分左右(group 2∶16.94±1.18，group 1∶9.89±1.29；p.05)，光镜和电镜检查发现wnt-3a蛋白对髓鞘形成和轴突再生有一定的修复效果。

High signal intensity in the lateral part, which corresponded to the lateral corticospinal tract of the cervical spinal cord was seen on T2 weighted images in 7 patients (cases 1, 2, 4, 6 and 11-13)(Fig.3 b).

在所有21例ALS患者中有7例患者（病例1、2、4、6、11~13）在T2像上于颈髓的皮质脊髓侧束区可见高信号病灶。

OBJECTIVE: To observe the effect of acrylamide on the degeneration and regeneration of sciatic nerve medullated fibers following crush injury of C57BL/Ola rat and C57BL/6J (6J) rat.

目的：观察丙烯酰胺对捻挫损伤后C57BL/Ola鼠和C57BL/6J(6J)鼠坐骨神经有髓纤维变性和再生的不同病理过程。

Bycomparison,a selection index,containing fleece weight,shorn body weight,fibrefineness,fibre densityand content of medullated fibre,was developed

经指数制订和比较，筛选出一个包括剪毛量、剪毛后体重、纤维细度、纤维密度和有髓毛含量等5个性状的综合选择指数

Objective To explore the changes of the white matter and the myelinated fibers in the white matter of aged rat brain.

目的 探讨老年大鼠大脑白质及白质内有髓神经纤维的改变。

Objective To investigate the effects of short-term enriched environment on the white matter and the myelinated fibers in the white matter of aged male rats.

目的 探讨短期丰富生存环境干预对老年雄性大鼠大脑白质及白质内有髓神经纤维的影响。

The results show that selective activation of small mammalian myelinated fibers may be possible in a region at some distance from the electrode using biphasic pulses.

结果表明：在距电极一定距离内采用该双向脉冲刺激模式确实可以实现哺乳动物有髓神经纤维的选择性兴奋。

A ≥ 3-level laminectomy with myelopathic motor symptoms may herald patients most likely to benefit from cervical fusion at the time of tumor resection.

椎板切除≥ 3节并有髓性运动症状的病人在肿瘤切除时行颈椎融合术对病人可能更有益。

Result:Characteristics of the tangentical longitudinal section of stem with resin and surface view of leaves were elucidated.Besides xylem vessels and fibers of the stem,it was found that the red resin also exists in the cortex parenchyma cells of the stem and the medulla and xylem of the root.According to the HPLC fingerprint analysis result of the stems with and without resin,a number of flavones and stilbenoids were detected in the stem in which resin appeared after it wounded.

结果：阐明了含树脂茎的纵切结构以及叶的表面观特征；除了茎木质部导管和纤维中有树脂外，发现剑叶龙血树受到损伤之后在茎皮层薄壁细胞、根的髓部和木质部亦有树脂的分布；含树脂茎和无树脂茎的指纹图谱显示剑叶龙血树茎在形成树脂后的化学成分中出现了较多的黄酮类、茋类成分。
