An Experimental Research on Effects of Fructus Ligustri Lucidi Extracts on Kidney Tissue and Exercise Capacity in Rats

Qi Shiyuan1,Xiong Zhengying2(1.Department of Physical Education,Xi’an Shoyou University,Xi’an 710065,China;2.College of Physical Education,Shaanxi Normal University,Xi’an 710062,China)  
The effect of Fructus Ligustri Lucidi extracts on kidney tissue and exercise capacity in rats was explored by probing the activities of antioxidant enzymes in the kidney of rats.Testing was conducted 6 weeks following an exhaustive exercise done on two groups:an exercise group alone and an exercise + LLE group.Measurements for the antioxidant enzyme activities of T-SOD,Cu,Zn-SOD,Mn-SOD and CAT and the content of GSH and MDA were taken.The antioxidant enzyme activity in the kidney of exercise + LLE group was significantly increased compared with the exercise group alone(P0.05);the content of GSH in the kidney of exercise + LLE group was higher than that of the exercise group alone(P0.05);the content of MDA in the kidney of exercise + LLE group was significantly decreased compared with the exercise group alone(P0.05);the time to exhaustion of exercise + LLE group was extended 23.09%.Adding LLE can improve the activities of the kidney antioxidant enzyme and the content of GSH,at the same time,decrease the content of MDA.Therefore LLE plays an important role in improving exercise capacity and delaying the fatigue time of organs in rats.
