Backgrounds : Electroacupuncture(EA) is commonly used in treatment of various disease. Despite an extensive evidence-base guiding the selection of stimulation parameters, little methodologically robust research regarding the level of intensity and frequency in need to provide effective doses. Objectives : This study is evaluated effects of various intensities and frequencies of EA’s stimulation at ST36, Zusanli, with sex and age in rats.
Methods : In this study, we measured the effects of EA treatment on transfer capability of small intestine in rats. Under anesthesia, two intensities, 1, 5mA with three different frequencies, 2, 50, 100Hz were applied to the groups divided with sex and age for 30minutes.
Results : 1mA-2Hz, 5mA-2, 100Hz in male and 1mA-2, 50, 100Hz in female without distinction of age elicited an increasing trend in transfer capability of small intestine. In case of 2Hz in male, it showed the effects of EA without strength or weakness of stimulation and it need 100Hz stimulation additionally with age. In the groups of 1mA-2Hz, 5mA-2Hz in male and 1mA-2Hz, 1mA-100Hz, we elicited the decreasing trend with growing of weeks-old in male.
Conclusions : With this result, it was suggested that we should consider a correlation of sex, age and EA’s intensities, frequencies for the efficient EA.
