摘　　要：本文通过研究一次性力竭运动后肥胖抵抗大鼠肝脏NO含量的变化,为更多人体研究提供理论依据。方法:对雌性清洁级SD大鼠经高脂饲料喂养后,选出30只符合标准的大鼠,随机分组,每组6只,建立大鼠游泳模型。适应性游泳三天,每天15分钟。第四天将四组大鼠进行一次性力竭运动。对一次性力竭运动无负重游泳即刻、2h、6h、12h后大鼠肝脏做石蜡切片,并采用免疫组织化学方法进行研究,观察NO含量的变化。结果:一次性力竭运动可以使肝脏中NO含量减少,但经过一段时间后NO含量会逐渐恢复到运动前水平。In this paper,the changes of NO content in liver of obese resistant rats after exhaustive exercise are studied,which provided theoretical basis for more human studies.Methods:after the female clean grade SD rats were fed with high fat diet,30 rats were randomly divided into six groups with 6 rats in each group to establish a swimming model.Adaptive swimming is executed for three days,15 minutes a day.On the fourth day,the four groups of rats were given one-off exhaustive exercise.The paraffin sections of rat liver were made immediately,2h,6h and 12 h after exhaustive exercise without load swimming,and the changes of NO content were observed by Immunohistochemical method.Result:once exhaustive exercise can reduce the content of NO in the liver,but after a period of time,the content of NO will gradually return to the pre-exercise level.
