银杏叶提取物对力竭训练大鼠血清酶活性的影响

摘要

选取SD雄性大鼠30只,体重为185～225 g.将雄性大鼠随机分成3组:银杏叶提取物组、运动对照组、安静对照组,每组10只.银杏叶提取物组与运动对照组进行6周的试验,最后1d训练至力竭,力竭后取血并进行样本处理,测定运动训练大鼠血清乳酸脱氢酶(LDH)、天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)和肌酸激酶(CK)活性.结果表明,银杏叶提取物组比运动对照组LDH、AST 、ALT、CK 活性均有所下降,银杏叶提取物可延缓大鼠运动疲劳的发生.%In order to study the effect of the extract from ginkgo biloba on the enzyme activity in the serum, 30 SD male rats whose weight were 185-225 g were randomly allocated to 3 groups of different treats fgr 6 weeks. At the end of training, the activity of lactic dehydrogenase (LDH), aspartate aminotransferase(AST), alanine aminotransterase(ALT) and creatine ki-nase(CK) in serum samples were detected and analyzed. The results showed that the actiyitiy of LDH, AST, ALT and CK in ginkgo biloba extract group were all lower than that in exhaustive training group. It was indicated that the extract of ginkgo biloba had an obvious effect on the rat's exercise performance and could alleviate the excise-induced fatigue.
