Objective To elucidate the underlying mechanisms of the high fatigability in mouse atrophic soleus during high-frequency tetanic contraction. 目的探讨萎缩比目鱼肌高频强直收缩疲劳性增加涉及细胞膜离子通道的可能机理。
At this time, the gastrointestinal manifestations, together with extreme weakness and fatigability, are the major symptoms. 复发时,胃肠道症状,同时伴有极度虚弱和乏力,为主要临床表现。
Results With the relaxing of skeletal muscles 'weakness and fatigability distinctive, the symptoms and results of lab test will improved and don't need treated by other special therapy. 结果所有患者的症状及实验室检查随MG典型的骨骼肌病态疲劳的症状好转而好转,未加其他特殊治疗。
Results Vertigo attack of PC-BPPV had such characters as brief period, positioning, latency and fatigability. 结果PC-BPPV患者眩晕发作具有短暂性、变位性、潜伏期和疲劳性等特点。
No influence of increased frequency on fatigability of tetanic contraction in rat atrophic soleus 增加刺激频率不影响大鼠萎缩比目鱼肌强直收缩疲劳性
Conclusions The clinical absolute score is correlated well with the electrophysiological parameters and can accurately and objectively reflect the severity and fatigability of muscular weakness in patients with MG. 结论临床绝对评分的高低与电生理的检查结果间有很好的一致性,能够比较准确、客观地反映MG病情的严重程度。
Effects of Olprinone on rat diaphragmatic fatigability induced by CLP 奥普利侬对细菌性腹膜炎致大鼠膈肌疲劳的影响
Weightlessness or simulated weightlessness has been shown to cause atrophy, to reduce contraction function, and to increase fatigability in rat hindlimb skeletal muscles. 航天失重或模拟失重能够引起下肢肌肉特别是抗重力肌发生废用性萎缩,并使肌肉的收缩力降低,疲劳性增加。
Conclusion These results suggest that the changes in K+ channel characteristics may increase the fatigability during high-frequency tetanic contraction in atrophic soleus. 结论萎缩比目鱼肌纤维膜上K+通道的改变,可能是引起其高频强直收缩疲劳性增加的主要因素。
P_ 33/ P_o ( P_ 33, 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. 但是,高频强直收缩第33秒收缩张力与最大张力之比(P33/Po)却明显降低。
