仙人掌对小鼠抗疲劳作用的实验研究

目的：以小鼠为实验对象，研究仙人掌对小鼠抗疲劳作用的影响。方法：分别以含8％和12％仙人掌的饲料饲喂小鼠，28天后测定小鼠的运动耐力，30天后测定小鼠的血清乳酸脱氢酶活力和肌糖原及肝糖原的含量。结果：与正常对照组比较，实验组的运动耐力和血清乳酸脱氢酶活力极显著增强（P＜0．01），肌糖原和肝糖原的贮备量大大增加（P＜0．01或P＜0．05）。结论：仙人掌具有明显增强小鼠运动耐力和延缓疲劳的作用。

Effects of opuntia dillenii on the delay of fatigue in rats

Objective: To study the effect of opuntia dillenii on the delay of fatigue in rats. Method: The rats were divided randomly into three groups :control group , opuntia I and opuntia II . Control group were fed with basic feed .Opuntia I were fed with basic feed 8% opuntia and opuntia II were fed with basic feed 12% opuntia.The swimming time of rat was determined after 28 days; the activity of serum lactate dehydrogenase(LDH) and the content of hepatic glycogen and muscular glycogen were determined after 30 days, respectively. Result: Compared with control, the sporting endurance and the activity of LDH significantly improved in the experimental rats ( P <0.01); and the content of hepatic glycogen and muscular glycogen evidently increased too ( P <0.01 or P <0.05).Conclusion: Opuntia dillenii had a significant effect on raising sporting endurance and delaying fatigue in rats.
