颏舌的

Objective To study the effects of ovariectomy on the muscle function of genioglossus in chronic intermittent hypoxia female rats and explore the possible mechanism of estrogen related with upper airway stability.

目的 检测慢性间歇性低氧雌性大鼠去卵巢后颏舌肌肌功能的变化，探索雌激素影响上气道稳定性的机制。

Microinjection of glutamate into the vMNF caused inhibitory response of the myoelectric activities of genioglossus.

结果表明：vMNF的兴奋能降低颏舌肌的肌电活动，从而提示其具有增强上呼吸道阻力的作用。

The effects of electrical and chemical stimulation of the vertral medial area of nucleus facialis on the myoelectric activities of genioglossus were observed in 26 urethane-anaesthetized and vagotomized rabbits.

本研究在26只氨基甲酸乙酯麻醉、断双侧迷走神经的健康成年家兔上观察了电、化学刺激面神经核腹内侧区对颏舌肌肌电活动的影响。

The above results suggest that excitation of nucleus raphe dorsalisincreases genioglossus activity and reduces upper airway resistance.The dNRD and vNRD play different roles in modulating diaphragm activity.

结果提示：中缝背核的兴奋可加强颏舌肌的活动，从而可能使上呼吸道阻力降低，其不同核区对呼吸有不同的调制作用。

Effects of electrical and chemical stimulation of the dorsal and ventral medial area of nucleus facialis on myoelectric activities of genioglossus and phrenic muscle were observed in 44 urethane-anaesthetized and vagotomized rabbits.

在44只氨基甲酸乙酯麻醉、断双侧迷走神经的健康成年家兔上，观察电、化学刺激面神经核背内侧区和腹内侧区对颏舌肌和膈肌肌电活动的影响。

Effects of electrical and chemical stimulation of the dorsal and ventral areas of the nucleus raphe dorslison genioglossus and diaphragm activities were observed in 48 urethan-anasthetized and vagotomized raddits.

本实验在48只氨基甲酸乙酯麻醉、断双侧迷走神经的健康家兔上观察了电、化学刺激中缝背核背侧区和腹侧区对颏舌肌和膈肌肌电积分活动的影响。

The effects of electrical and chemical stimulation at nucleus rape dorsalis and nucleus raphe magnus on genioglossus and phrenic muscle activities and amplitude augmenting response to apnea were observed.

本实验在64只氨基甲酸乙酯麻醉、断双侧迷走神经、自主呼吸的健康家兔上进行，观察电、化学刺激中缝背核、中缝大核对颏舌肌和膈肌肌电、以及窒息增幅反应的作用。

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。

RESULTS:①There was higher tensile stress at the ingual side of symphysis, inside of molar and outside of condyle under the impact of chin.②There was higher tensile stress at the lingual side of symphysis, inside of contralateral molar, outside of contralateral angle, outside of homolateral angle and inside of homolateral body under the impact of body.③There was higher tensile stress at the inside of angle, inside of homolateral condyle, lingual side of symphysis, outside of contralateral condyle and inside of homolateral molar under the impact of angle.

结果：①撞击颏部，其舌侧区，磨牙后区内侧面、髁状突颈外表面以及下颌角外表面具有较高的张应力；②撞击下颌体部，颏部舌侧区，对侧磨牙后区内侧面、对侧下颌角外表面、撞击侧下颌角外侧面、撞击侧体部内侧面具有较高的张应力；③撞击下颌角，其内侧面、撞击侧髁状突颈内侧面、颏部舌侧面、对侧髁状突颈外表面以及撞击侧磨牙后区内侧面具有较高的张应力。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
