The formula of lowered cholesterol quail egg yolkjujube powder(LCDP),and the effects of lowered cholesterol quail egg yolk powder(LCP) and LCDP on endurance and antioxidative capacity of rats were studied.Their functional action was compared with quail egg yolk powder(QEP).The results showed that the optimum formula of LCDP was jujube powder:LCP(w/w)ratio of 7∶3.It was concluded that LCP and LCDP had the roles in strengthening rats' endurance,since they greatly prolonged the time of rats` swimming.Both LCP and LCDP noticeably reduced the activities of superoxide dimutase(SOD)and glutathione peroxidase(GSH-Px),and the elevation of malonyldialdehyde(MDA)in blood,liver and brain of rat induced by alloxan.These results suggested that LCP and LCDP significantly removed active free radicals,and increased antioxidative capacity of rats.Their biological functions were better than QEP.

对低胆固醇鹌鹑蛋黄红枣粉(LCDP)的配方进行了优选,并研究了低胆固醇鹌鹑蛋黄粉(LCP)和LCDP对小鼠耐力和抗氧化能力的影响,且与鹌鹑蛋黄粉(QEP)的功能作用进行了比较。结果表明,LCP与红枣粉的最佳配比为7∶3;LCP、LCDP均能显著延长小鼠游泳时间,说明它们能增强小鼠耐力,且比QEP的作用强;LCP和LCDP均可显著降低四氧嘧啶致小鼠血液、肝脏及脑组织超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(G SH-Px)的活性,同时丙二醛(M DA)生成量显著下降。说明LCP和LCDP对四氧嘧啶致小鼠生物膜的氧化损伤均有保护作用,这种保护作用与它们对自由基强的清除能力是分不开的,且这种保护作用优于QEP。

BACKGROUND: Gingko leaf extract has multiple functions by dilating blood vessels, promoting blood circulation, eliminating free radicals, and protecting organism tissues. It has remarkable effects on the prevention and treatment of cardiovascular diseases. Although clinical and pharmacological studies on it have been widely conducted, research regarding athletic health protection, as well as anti-athletic fatigue and the improvement of animal or human athletic ability is less available. OBJECTIVE: To explore the effects of gingko leaf extract on rat endurance and anti-fatigue capability, so as to provide basis for developing new athletic tonic as well as further studies on the effects of gingko leaf extract on the athletic capability. DESIGN: Randomized controlled study. SETTING: Athletic Physiological Laboratory, Sports Institute of Guangxi Normal University. MATERIALS: This experiment was carried out in the Athletic Physiological Laboratory, Sports Institute of Guangxi Teachers' Training University, between September and November 2003. Totally 60 healthy Kunming rats with normal swimming capability were included after birth of 8 weeks, and randomized into five groups according to their body mass: rest control group, rest administration group, post-exhaustion administration group, training control group, and administration training group with 12 rats in each group. Gingko leaf extract powder (containing 24% of total flavone and 6% of gingko lactone); 60 healthy male Kunming rats after birth of 8 weeks, weighing 23-27 g. METHODS: Rats were given medicine by gastric perfusion or placebo. According to the experiment scheme, swimming training, rope crawling and exhaustion swimming experiments were carried out on rats.MAIN OUTCOME MEASURES: ① Comparison of rope crawling capability between groups. ② Comparison of exhaustion swimming capability between groups.RESULTS: During the first 3 weeks of low load training, all rats in training control group and administration training group could complete the designed training tasks, but in the fourth week, the training tasks could be completed without breaks in the 6-day training by (83.34±10.45) % rats in training control group and (94.45±4.3) % rats in administration training group. The rat number dropped to (79.17±6.97) % and (88.95±6.75) %, respectively, in the fifth week. ① Rope crawling capability of rats in rest administration group was obviously stronger than that in rest control group (P < 0.05); it was also proved to have a stronger tendency in administration training group than in training control group, but with no significant (0.1> P > 0.05). ② The loaded swimming ability of rats in rest administration group presented an obviously increasing tendency compared to that in rest control group, but the difference was not significant (0.1> P > 0.05). However, it was stronger in administration training group than in training control group, with extremely remarkable significance (P < 0.01). After 6-day exhausting exercise once a day, the loaded swimming ability and anti-fatigue ability were obviously stronger in rats of rest administration group than in rest control group, and the difference began to have statistical meaning from the onset of the 3rd exercise (P < 0.05). After given gingko leaf extract, rats in post-exhaustion administration group could swim for a longer time than rest control group. However, the comparison between rest administration group and post-exhaustion administration group was the opposite. The swimming ability differed significantly in the first 3 exercises, but the difference was reduced with the increase of administration times, which was proved insignificant at the last 3 exercises (P > 0.05). The athletic ability in administration training group was obviously higher than in training control group, with extremely significant difference (P < 0.01). CONCLUSION: Administration of gingko leaf extract alone without athletic training cannot obviously improve rats' athletic capability, but it has a positive effect in attenuating athletic fatigue. The synergic effect of athletic training and administration of gingko leaf extract can remarkably enhance rats' athletic capability, particularly muscular endurance and cardiopulmonary endurance. Therefore, taking gingko leaf extract can enhance rats' tolerance to fatigue, delay the occurrence of fatigue, eliminate endurance-related athletic fatigue, and promote the recovery of physical strength.
