收缩肌

The buccal frenum is also a fold of mucous membrane, but varies in shape from a single fold to a broad fan. The levator anguli oris muscle passes beneath it and its action affects its position, as does theorbicularis oris and the buccinator. The former pulls the frenum forwards, the latter backwards.

颊系带同样是一个粘膜皱襞，但形态，从一个细窄条带状到宽平如盘状而变化多样；提口角肌从其下通过，并在收缩时影响颊系带的位置；同样，口轮匝肌和咬肌，前者使颊系带向前，后者使其向后运动。

方法9名健康被试者参加了试验，包括最大自主收缩力(maximum volunteer contraction，MVC)，80%MVC及40%MVC，记录指浅屈肌和腕长伸肌的表面肌电信号，并采用均方根和小波分析方法提取其特征参数；运用SPSS软件统计以被试者自身的MVC为基准的不同握力水平的相对特征值，使不同的被试者具有可比性。

Methods: The action potential of sciatic trunk and contract curve of gastrocnemius muscle of hoptoad and mouse were recorded, and the time of fatigue in nerve centre, neuromuscular junction and muscle were measured.

分别记录蟾蜍和小鼠坐骨神经干动作电位和腓肠肌收缩曲线，测定中枢、神经-肌接头和肌疲劳的时间。

The commonest protein in muscle cells, responsible for the elastic and contractile properties of muscle.

肌球蛋白在肌肉细胞中最普通的蛋白质，对肌肉的弹性和收缩性的特性很重要，它与肌动朊结合形成肌动球朊

This overactive muscle response is referred to by doctors as spastic hypertonia.

这种肌反应过度被称作痉挛性张力亢进，临床表现为：不可控的急跳运动，肌肉僵硬，强直，肌肉或肌群收缩，肌张力异常。

These conditions are distinguished by the presence of clinical and electrical myotonia and a delay in muscle relaxation after contraction because of prolonged excitation of the muscle membrane.

肌强直综合征可以通过以下表现加以鉴别：临床检查及电生理检测军发现肌强直、因肌膜兴奋性延长所致的肌肉收缩后松弛延时缓慢。

The contractile tension of the masster, digastric and lateral pterygoid muscles varied according to the mandibular position, being greatest when the mandible was opened at an interin- cisal distance of 13mm, protruded 6mm and retrated 1mm.

正常4周龄大鼠嚼肌、二腹肌前腹、翼外肌的最大收缩张力分别位于打开下颌切牙间距离13mm、下颌前伸6mm和下颌后退1mm时。

Methods: Eleven healthy young male volunteers enrolled in this study. Testing MVC of back extensor before the experiment. The experiment collected sEMG signal at which T12-L1 segment lumbar multifidus and L5-S1 erector spinae in different directions, with different load ways, different load levels and different road conditions.

10名健康青年男性志愿者，实验前测试其背伸肌最大随意收缩力，采集被试在不同方向上的躯干运动时与不同负荷方式、负荷等级及路面条件下行走时T12-L1节段左右侧竖脊肌与L5-S1节段左右侧多裂肌的sEMG信号。

Methods: The motion of parasternal papillary muscle anterior wall, inferior wall, posterior wall, and lateral wall were detected by 2DE at short axis view of left ventricle before PTCA, 3 d and 1-3 months after PTCA in 33 cases of patients with coronary heart disease, who received PTCA+stent at selected time. Peak systolic velocity of subendocardial, subepicardial and middle layer myocardium, transmural velocity difference of the same segments and Outer lateral mitral valve annulus were also detected at apical 4 chamber view by pulsed wave tissue Doppler imaging.

对33例择期行PTCA+支架术的冠心病患者用HP5500型超声诊断仪，于PTCA术前及术后3d、1-3个月对胸骨旁左心室乳头肌短轴切面的前间壁、下壁、后壁、侧壁行二维超声心动图(2DE)检测各节段的室壁运动情况，用脉冲组织多普勒成像检测上述各节段的内、外膜下及中层心肌的收缩期峰值速度，内外膜下心肌的收缩速度差及心尖四腔观二尖瓣外侧环的收缩期峰值速度。

Motilin and gastrin induced contraction of isolated gastric smooth muscle cells in a dose-dependent manner.(2) Motilin- and gastrin-induced antral smooth muscle cell contraction was inhibited by antibodies against Gαi-3. Motilin and gastrin caused an increase of Guanosine-5′-(3-［35S］thio)triphosphate(［35S］GTPγS) binding of Gαi-3.(3) Contraction of antral muscle cells induced by motilin and gastrin was inhibited by the phospholipase C inhibitor U-73122 and the IP3 receptor antagonist heparin.

结果显示：(1)胃动素和胃泌素对胃窦平滑肌细胞均有收缩作用；(2) Gαi-3抗体可抑制胃动素和胃泌素加强胃窦平滑肌细胞的收缩，胃动素、胃泌素明显增加Gαi-3抗体与［35S］GTPγS的结合；(3)磷脂酶C抑制剂U-73122、三磷酸肌醇受体拮抗剂肝素可抑制胃动素和胃泌素引起的胃窦平滑肌细胞的收缩。

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。
