舌骨

This indicated that geniohyoid paralleling with the direction of distraction presents adaptive changes such as muscular hypertrophy and muscle fiber type transformation.

这说明与牵张方向平行的颊舌骨肌在牵张过程中出现了肌肉增生与肌纤维类型转变等适应性变化，而与牵张方向垂直的嚼肌受其影响不大。

The result showed that,in geniohyoid, the MHCImRNA was upregulated and MHCIImRNA was repressed; the amount of MHCI/MHCH and MHCI+MHCIIwere also increased, and then restored normal level at the end of experiment. In masseter there was no significant difference in all of detecting result.

结果显示：在牵张过程中，嚼肌中各项检查指标变化不大，与对照相比无显著性差异；额舌骨肌中MHCI表达上调，MHCH表达受到抑制，MHCI＋MHCll与MHCllMHCll升高，但在固定8周时基本恢复正常。

Differential expression of IGF-I in muscles of mastication during distraction osteogenesis of mandible in canine.This study was conducted to observe the expression of IGF-I in masseter and geniohyoid during distraction osteogenesis of mandible in canine through the immuno-histocytochemical method.

试验三犬下颌骨牵张成骨过程中咀嚼肌IGF.I的表达变化将所取标本进行免疫组化染色，检测犬下颌骨牵张成骨过程中嚼肌与颁舌骨肌中IGF.I表达的变化。

During the procedure of distraction, geniohyoid expressed hypertrophy and hyperplasia initially and then restore normal level after distraction, while masseters was influenced rarely.

结果发现在牵张过程中，颏舌骨肌先是发生再生与肥大，最终组织学形态恢复至牵张前的形态；而嚼肌受其影响不大，只是在牵张5天时有轻度的萎缩，可能与牵张过程中引起的干扰有关。

In this experiment, in the way of observing the histological changes, relative content of myosin heavy-chain mRNA and changes of the expression of IGF-I in masseter and geniohyoid muscle during distraction osteogenesis of canines mandible, we can learn about the rebuilding ability of masticatorymuscles and its changing regularity, and preliminarily discuss its remodeling mechanism.Anteroposterior bilateral distraction osteogenesis was performed on 14 mongrel canines, 6 to 8 months of age, using intraoral mandibular distractor.

本实验通过观察犬下颌骨牵张成骨过程中嚼肌与颏舌骨肌的组织学变化、肌球蛋白重链亚型mRNA含量以及IGF-I在咀嚼肌中表达的变化，了解牵张成骨过程中口颌肌肉的改建能力及其变化规律并初步探讨其改建机制。

All the muscles rebuilt to stable structure after accomplish of distraction, which may help the post-operative stability.2. The changes of myosin heavy-chain mRNA in muscles of mastication during distraction osteogenesis of mandible in canineThe mRNA of MHCI, MHCH and GAPDH in masseter and geniohyoid were measured by RT-PCR.

试验二犬下颌骨牵张成骨过程中咀嚼肌肌球蛋白重链亚型mRNA含量的变化将所取标本应用RT－PCR对嚼肌与颌舌骨肌肌球蛋白重链的两个亚型，即MHCI与MHCll与内参照GAPDH的InRNA进行半定量检测并进行统计学分析。

Methods: We summarized retrospectively on the clinical data of 104 patients with carcinoma of head and neck reconstructed at the same stage of tumor resection by 4 types of island myocutaneous, including forehead, infrahyoid, trapezius and pectoralis major myocutaneous flap.

回顾性分析1985-2003年本科收治的104例头颈部肿瘤患者术后应用4种岛状肌皮瓣（额瓣、舌骨下肌皮瓣、斜方肌皮瓣、胸大肌皮瓣）进行一期修复的临床资料。

Tracheal autograft wrapped in one-side sternomastiod muscule flap and two-side stemohyoid muscle flap based on different pedicle can acquire enough blood supply, and are revascularized.

以上方或下方为蒂的单侧胸骨乳突肌瓣和双侧胸骨舌骨肌瓣不管采用何种方式包裹移植气管，均能使移植气管获得可靠的血运，发生再血管化，使实验动物长期存活。

Objective To provide anatomical basis for maki ng sure the smooth anastomosis of mylohyoid nerve with facial nerve.

目的 为确保面神经与下颌舌骨神经顺利吻合提供参考。

Methods 25 (50 sides) adult skulls were dissected to observe the c ourse, distribution and bilateral anastomosing branches of the mylohyoid nerve.

在25具(50例)尸头上解剖观察了下颌舌骨神经在颌下的走行、分支及双侧分支吻合情况。
