中文摘要：

目的探索低频电刺激对不同动物血内激素水平的影响。方法分别给予中国树鼩、Wistar大鼠、BALB/c小鼠低频电刺激后,分别在12、24、36 h各取一组动物采血,用放射免疫法检测去甲肾上腺素(noradrenaline,NA)、内皮素(endothelin,ET)水平。结果给予中国树鼩、Wistar大鼠、BALB/c小鼠低频电刺激后12、24、36 h,NA、ET水平比对照组显著升高(P<0.01),给予利血平后24 h,再给予相同电刺激,NA、ET水平比单纯电刺激组明显降低(P<0.05~0.01)。不同动物对同一刺激的应激敏感程度不同,敏感程度按照中国树鼩、Wistar大鼠、BALB/c小鼠的顺序依次降低。结论低频电刺激能促进中国树鼩、Wistar大鼠、BALB/c小鼠NA、ET释放,利血平具有降低机体对低频电刺激的应激作用。

英文摘要：

Objective To study the effect of low frequency electrical stimulation on blood hormone levels in differ -ent animals.Methods At 12 h, 24 h and 36 h after low frequency electrical stimulation to Chinese tree shrews , Wistar rats, and BALB/c mice, respectively, the blood noradrenaline (NA) and endothelin (ET) levels were determined by ra-dioimmunoassay ( RIA) .Results The blood NA and ET levels of electrical stimulation group were significantly higher than that in the control group (P <0.01).At 24 h after reserpine treatment, the same electrical stimulation was given. The NA, ET levels were significantly decreased compared with that in the electrical stimulation group (P<0.05 to 0.01). Different animals responded to the same electric stimulus differently , following the order of Chinese tree shrews >Wistar rats >BALB/c mice.Conclusions Low frequency electrical stimulation can promote the release of noradrenaline and en -dothelin in Chinese tree shrews , Wistar rats and BALB/c mice.Reserpine can reduce the stress induced by low frequency electric stimulation to the body .
