脊柱

Fifteen chickens, a antagonist of the MEL1-a receptor of melatonin (Luzindole, 30mg/kg) was injected abdominally every day when they were 3 days old.

探讨鸡腹腔内注射褪黑素受体拮抗剂对鸡脊柱发育的影响刚孵育出的国产绍兴小鸡45只，随机分 3组，每组15只。

Furthermore, muscles of the abdominal wall (external abdominal oblique, internal abdominal oblique, transversus abdominis, and rectus abdominous) may be contracted, stabilizing the spine during heavy lifting or sudden, explosive movement.

另外，腹腔壁的肌肉（外斜肌，内斜肌、横肌和直肌）在人体进行举重和突然的爆发性的运动时，通过收缩来保持脊柱稳定。

We established the NTD model and showed that the central nervous system malformation at age of embryonic day 10.5(E10.5) included acrania, craniofacial abnormal, spina bifida, short-tailed or tailless ect.

对孕7.5d母鼠一次性喂服50mg/kg RA后观察到E10.5d鼠胚有颅脑顶部未闭、后脑及面部异常、脊柱或尾部有裂口以及无尾或短尾等多种畸形的发生，大部分与神经系统有关。

METHODS: From January 2000 to May 2002, 52 cases with various types of bone defect were treated with tissue engineered bone, which was constructed in vitro by allogeneous osteoblasts from periosteum 1 x 10(6/ml with bio-derived bone scaffold following 3 to 7 days co-culture. Among them, there were 7 cases of bone cyst, 22 cases of non-union or malunion of old fracture, 15 cases of fresh comminuted fracture of bone defect, 4 cases of spinal fracture and posterior route spinal fusion, 3 cases of bone implant of alveolar bone, 1 case of fusion of tarsotarsal joint.

2000年1月～ 2002年1月，用同种异体骨膜来源的成骨细胞 1×106 / ml与生物衍生骨支架材料构建的组织工程骨，经体外培养 3～ 7天后，植入修复52例各种类型的骨缺损，其中骨囊性病变7例，陈旧性骨折不愈合或畸形愈合 2 2例，新鲜粉碎性骨折伴骨缺损 15例，脊柱骨折后路植骨融合术4例，牙槽骨植骨 3例，足跗中关节植骨融合 1例。

An important difference between humans and other vertebrates is the fact that humans ambulate in a fully erect position.

由于人是直立行走的，所以特发性脊柱侧凸是人类特有的一种疾病状态。

The investigators concluded patients who have never walked are not at risk for spondylolisthesis because their spines are not subject to the same forces as those who ambulate.

作者认为：从未行走过的人不存在脊椎前移的风险，因为他们的脊柱受力和行走的人不一样。

To evaluate the efficacy of epsilon aminocaproic acid to reduce the number of red-cell transfusions in adult patients undergoing major spinal surgery. SUMMARY OF BACKGROUND DATA.

目的：探讨6-氨基己酸对于降低接受脊柱大手术成人患者红细胞输注量的疗效。

Objective: To provide anatomic data for the optimal approach in cervicothoracic spine region.

目的：为颈胸段脊柱选择合理的手术入路提供解剖学依据。

Anterior retropharyngeal soft tissue swelling, widening of the disc space, high fluid signal in an otherwise degenerative disc space along with avulsion fractures of anterior osteophytes, or the anteroinferior corner of a vertebral body all point to this pattern of injury.

过度伸展损伤±撕脱骨折。通常认为，过度伸展损伤发生于老年患者伴随有颈椎病或僵硬的脊柱（图3）。

Macroscopically, each facet joint is composed of a posteromedially facing concave superior articularprocess from the inferior vertebral body, and as maller anterolaterally facing inferior articular processfrom the superior spinal level.

大体观，每个小关节由下位椎体朝向后内侧凹陷的上关节突以及上位椎体朝向前外侧的的下关节突组成。L-z关节的形状及朝向决定了其作用为阻止脊柱过度运动。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
