本研究旨在通过持续刺激兔快型骨骼肌10个月,观察肌纤维对不同频率刺激的生理和生化反应。 资料与方法 选用18只同一性别、体重为2.0～3.0 kg的新西兰大白兔,平均分为3组。对每组均予左后肢胫前肌(TA)连续刺激24h/d,共10个月。在严格无菌条件下,把一小型电刺激器植入胁腹部皮肤下。电极被放置在腓总神经附近,3组的频率分别为:2.5,5和10Hz。在10个月后,作如下步
This study aimed to observe the physiological and biochemical responses of muscle fibers to different frequency stimuli by continuously stimulating rabbit fast skeletal muscle for 10 months. Materials and Methods 18 New Zealand white rabbits with the same sex and 2.0 ~ 3.0 kg body weight were divided into 3 groups. For each group, left tibialis anterior tibialis muscle (TA) was continuously stimulated for 24h / d for 10 months. Under strict aseptic conditions, a small electrical stimulator is implanted under the flank of the abdomen. Electrodes were placed in the vicinity of the common peroneal nerve and the frequencies of the three groups were 2.5, 5 and 10 Hz, respectively. After 10 months, take the following steps
