肌强直

The present study was performed to observe the time course and features of intermittent tetanic contractile function changes in soleus and extensor digitorum longus muscles of tail-suspended rats. The optimal stimulating frequency, fatigability and time-dependent recovery after fatigue were measured in isolated muscle strips.

为观察模拟失重对大鼠比目鱼肌(soleus， SOL)与趾长伸肌(extensor digitorum longus， EDL)间断强直收缩功能的影响，以及对刺激频率的调节作用，采用离体骨骼肌条灌流技术，观测其产生强直收缩最大张力的最适刺激频率、疲劳性与疲劳后恢复过程。

Result Maximal tension P(subscript o of soleus tetanic contraction showed no difference between control and 1-week tail-suspension group. P33/P (P33, transient tension of tetanic contraction at the 33 s) was reduced significantly in SUS, and it manifested an increase in fatigability during tetanic contraction in SUS.

结果 在生理溶液灌流下，悬吊1周组小鼠比目鱼肌高频强直收缩的最大张力P(下标 o与其同步对照组相比，仅有降低趋势；但是，高频强直收缩第33秒收缩张力与最大张力之比P33/P

These goats in Tennessee, myotonic goats, will actually "faint" once they got startled.

这些在田纳西的山羊－－肌强直羊，一旦它们受到惊吓，就会&昏倒&。

A disorder due to a similar molecular basis, myotonic dystrophy 1 (DM1), is known to have white matter hyperintensities on cranial MRI.

另一种有类似分子病理学基础的疾病：萎缩性肌强直(DM1)患者的核磁共振成像也有白质高信号。

The diagnosis of ALS was established clinically on the basis of the history and physical and electrophysiological examinations. In five patients (cases 1-5), the initial symptoms were spastic paraparesis.

21例ALS患者中有5例（病例1~5）首发症状为下肢痉挛性轻瘫，在病程进展过程中均出现上运动神经元症状体征，包括肌强直、腱反射亢进、Babinski征，尤以病例2、病例4的患者明显。

RESULTS The ethanol extract of the Huangqi could shorten latent period,increase maximal contractive extent and time and relaxative time at the twitch and complete tetanus of gastrocnemius and soleus muscles.

结果］ 黄芪酒精提取液缩短腓肠肌及比目鱼肌单收缩和完全性强直收缩潜伏期，增加单收缩最大收缩幅度，延长最大收缩时间及最大舒张时间；增加完全性强直收缩的最大收缩度，延长最大收缩时间。

objective to study the effects of ethanol extract of the huangqi on the skeletal muscles contractility in rats.methods the gastrocnemius and soleus muscle contractility were observed by stimulating the sciatic nerve with electricity after affusing stomach with ethanol extract of the200mg/kg dosage of huangqi for2weeks.results the ethanol extract of the huangqi could shorten latent period,increase maximal contractive extent and time and relaxative time at the twitch and complete tetanus of gastrocnemius and soleus muscles.conclusion the ethanol extract of the huangqi can enhance skeletal muscles contractility in rats.

方法］ 灌胃给予200mg/kg黄芪酒精提取液2周后，观察大鼠坐骨神经受刺激后腓肠肌及比目鱼肌的收缩力。［结果］黄芪酒精提取液缩短腓肠肌及比目鱼肌单收缩和完全性强直收缩潜伏期，增加单收缩最大收缩幅度，延长最大收缩时间及最大舒张时间；增加完全性强直收缩的最大收缩度，延长最大收缩时间。［结论］黄芪酒精提取液可增强大鼠骨骼肌的收缩力。

There were no limp,ulceration and phenomena of self-injury.Normal wave figure in EMG was noted in the experimental side. There was no significant difference in t test in EMG wave amplitude,maximum tetanized systole tensile strength and duration of isometric contraction.

结果 术后大鼠两侧姿态对称，未见跛行，无溃疡及自残现象，对疼痛刺激敏感；实验侧肱二头肌和指深屈肌肌电图均呈正常波形；两侧肌电图波幅、等长收缩时最大强直收缩张力及持续时间进行自身t检验比较均无显著差异。

By RNA fluorescent in situ hybridization, the muscle cells of200 mice were shown to contain nuclear retentions of transcripts, or nuclear foci.

在肌肉电生理方面，我们并没有很明显的看见200有肌强直的情形。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
