针刺对肥胖大鼠海马组织一氧化氮含量和一氧化氮合酶活性的影响刘志诚等


  [摘 要]目的:探讨针刺对肥胖大鼠海马组织一氧化氮(NO)含量和一氧化氮合酶(NOS)活性的影响。方法:观察针刺治疗前后肥胖大鼠体重、体脂及海马组织NO含量和NOS活性的变化。结果:肥胖大鼠体重、体脂及海马组织NO含量和NOS活性均显着高于正常大鼠水平;大鼠海马组织NO含量和NOS活性与体重和Lee’s指数高度正相关。针刺治疗取得良好减肥疗效。同时,肥胖大鼠海马组织NO含量和NOS活性明显回降。结论:海马组织NO含量和NOS活性异常可能是肥胖发病 因素之一;针刺对肥胖机体海马组织NO含量和NOS活性的良性调整作用,可能是实现减肥效 应的中枢作用机制之一。

  ABSTRACT Objective To study effect of acupuncture on the c ontent of

nitric oxide (NO) and the activity of nitric oxide synthase (NOS) in the

hippocampus of the obese rat. Methods The changes of body we ight, body fat,

and content of NO and activity of NOS in the hippocampus befor e and after

acupuncture were observed. Results The body weight, body fat, and the content

of NO and the activity of NOS in the hippocampus all were significantly higher

than those in the normal rat; there were high positive correlation of the levels

of NO and activities of NOS in the hippocampus with the body weight, Lee’s

index; after acupuncture treatment, the marked weight reduction effect was

achieved, and the level of NO and the activity of NOS in the hippocampus de

creased significantly. Conclusion Abnormal levels of NO and a ctivities of NOS

in the hippocampus may be an important factor for obesity; the benign

regulation of acupuncture on the level of NO and the activity of NOS in the

hippocampus is possibly one of the central nervous mechanisms of reducing body

weight.
