振动负荷对家兔骨骼肌能量物质影响的实验研究

EFFECTS OF VIBRATIONAL LOADING ON EMERGY MATERIALS CONTENT IN SKELETAL MUSCLE OF RABBITS

选择体重１５～２１ｋｇ的健康家兔２４只（雌、雄各半），随机分为Ａ、Ｂ和对照组，采用美国产Ｂｉｏ－Ｒａｄ７００型高压液相色谱仪及其附属系统，测定家兔骨骼肌中的能量物质（ＡＴＰ、ＡＤＰ和ＡＭＰ）。结果发现：振动负荷６０天时，骨骼肌中ＡＴＰ减少，Ａ组、Ｂ组与对照组相比较分别减少４１％和１３９％，Ｂ组较Ａ组减少幅度较大；ＡＤＰ和ＡＭＰ含量增加，ＡＤＰ分别增加９６％和１７３％，ＡＭＰ分别增加１３％和１２９％，且Ｂ组增加有显著性差异。说明振动负荷对机体骨骼肌正常的能量代谢有影响。

Rabbits were randomly separated into A and B and control groups. Emergy materials(ATP、ADP and AMP) content in skeletal muscle of rabbits exposed to vibration were measured with high performance liquid chromatography (HPLC) at 60 days. This result showed emergy materials in skeletal muscle have changed. ATP decresaed, ADP and AMP increased. Therefore, the result indicated that there were effects vibrational loading on emergy materials metabolism in skeletal muscle.
