收缩肌

Methods The electromyogram of a dog's orbicularis oculi muscle was extracted with implanted micro-electrodes, The difference of electromyographic activities during different functional states was investigated to establish a way for real-time identification of functional states.

结果 眼轮匝肌在收缩时的肌电信号相对于舒张状态有幅值显著增加的特点，基于这种特征，我们采用了一种带延迟判断的幅度阈值方法，对信号进行实时分析，以接近于同步的方式识别出了眼轮匝肌收缩动作的发生。

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.

The in vitro effects of Gln49-PLA_2 were examined using the chick biventer cervicis nerve muscle preparation. Gln49-PLA_2 caused a dosedependent blockade of neuromuscular transmission. The time required to cause 50% blockade was about 150 min at the highest concentration 100μg/ml. This inhibition appeared to be presynaptic in origin as evidenced by the lack of effect of toxin on responses to exogenous acetylcholine in the non-stimulated BCp.

Gln49-PLA_2能够剂量依赖性地抑制颈二腹肌神经信号正常传导并影响肌肉收缩，在100μg/ml剂量下，肌肉收缩幅度在150分钟后达到50%的抑制率；同时，随着Gln49-PLA_2浓度的降低，肌肉收缩幅度的抑制效率也逐渐降低；实验证明Gln49-PLA_2对突触后膜乙酰胆碱受体敏感性无影响，对神经肌肉信号传导收缩的抑制作用位点在突触前膜。
