영문 초록

By measuring changes in blood lactate and plasma enzyme (CPK, GOT, GPT) with electrical stimulation applied at two duty cycles, this study is intended to look into which type of duty cycle may have more effects on blood lactate and plasma enzyme constituents through animal experiment so as to determine any duty cycle appropriate for electrical treatment. In this study, electrical stimulation was applied to total 20 Korean house rabbits (weight: 3~3.5 ㎏) by means of an electrical therapeutic apparatus called TS6000 (made in Netherlands) at duty cycle of 50% and 20% respectively for 30 minutes. Here, 5 ㏄ of blood was collected from their carotid artery before stimulation and in 30 minutes after stimulation respectively to carry out biochemical experiment and analysis. As determined through the above experiment, blood lactate rate was increased to 333.07% at 50% duty cycle after experiment and 185.71% at 20% duty cycle after experiment respectively. In both cases, blood lactate rate was significantly increased to higher level after electrical stimulation than before. Moreover, the rate of change in the average of blood lactate rate at both duty cycles also showed significant differences. CPK rate was boosted to 301.82% at 50% duty cycle after experiment and 321.35% at 20% duty cycle after experiment respectively. In both cases, CPK rate was remarkably boosted to higher level after stimulation than before (p＜.05). However, there was not any significant difference in the rate of change in average CPK at both duty cycles (p＜.05). GOT rate was significantly boosted up to 38.97% at 50% duty cycle after experiment (p＜.05), while it was slightly increased to 1.68% at 20% duty cycle after experiment without any significant difference. Rather, GPT rate dropped slightly at both duty cycles after experiment, but there was not any significant difference. Although blood lactate and GOT were relatively less generated at 20% duty cycle after electrical stimulation than at 50% duty cycle, the change of duly cycle didn’t have any significant influence on CPK rate. In this regard, this study failed to come any consistent conclusion about the association between change of duty cycle and muscle fatigue. Therefore, it is advisable that follow-up studies seek various ways to a little more effectively apply electrical stimulation to laboratory animals by avoiding their muscle fatigue GOT rate was significantly boosted up to 38.97% at 50% duty cycle after experiment (p＜.05), while it was slightly increased to 1.68% at 20% duty cycle after experiment without any significant difference.
