Abstract:
BACKGROUND: To tonify qi, benefit spleen and primary qi, strengthen tendons and bones and promote circulations in meridians and collaterals are the classical principles in Chinese medicine for anti-kinetic fatigue.OBJECTIVE: To observe the efficacy of compound Chinese herbal medicine on anti-kinetic fatigue.DESIGN: Randomized controlled experiment based on animals.SETTINGS: Animal Experimental Center of Wenzhou Normal University and Zhejiang College of Traditional Chinese Medicine.MATERIALS: The experiment was performed in Animal Experimental Center of Zhejiang College of Traditional Chinese Medicine from February to June 2001, in which, 80 ICR mice of either sex, body weighted(22±2) g and 40 SD male rats, body weighted(194±7) g were employed.ETHODS: ① Eighty mice were randomized into two groups, of which, 40 mice was gastric-infused with Chinese herbal fiang li fang(experimental group) and 40 mice was with physiological saline (the control) . After bred for 15 days, they were randomized into 3 groups for anti-fatigue experiment ( n = 15, swimming time), anti-hypoxia ability( n = 15) and determination of hemoglobin(n=10). ② Determination of testosterone: Forty rats were randomized into 4 groups, named the control with physiological saline infusion, herbal infusion group, exercise group, exercise-herbal infusion group. In herbal infusion group, the rats were infused once a day. In exercise group and exercise-herbal infusion group, the rats exercised once a day, swimming till being exhausted at the tolerance of 3% body weight at 28 ℃ of water temperature. After bred for 20 days, heart blood 2 mL was collected with chest opened and the serum was centrifuged and placed in refrigerator at 4 ℃. Minigamma 1275γ counter and VCS method were applied for determina tion.MAIN OUTCOME MEASURES: ① Determination of swimming time of mice in every group. ③ Time of anti-hypoxia. ③ Levels of hemoglobin and testosterone in rats.RESULTS: Forty rats and 80 mice were all entered the result analysis. ①Observation of swimming time in mice: The time was remarkably prolonged in experimental group compared with the control[ (125.2±13.7), (108.9 ±12.6) minutes, P＜0.01] . ② Anti-hypoxia ability: It was much improved in experimental group compared with the control[(25.0±l.5),(23.1 ±1.8) minutes, P ＜0.05] . ③ Level of hemoglobin: The level of hemoglobin in experimental group was higher than that in the control, but the difference was not significant[(162.1 ±5.2), (159.3 ±5.3) g/L] . ④Level of testosterone: That in exercise group of rats was remarkably lower than exercise-herbal infusion group[(4.69 ±0.92), (6.03 ±0.77) nmol/L,P ＜ 0.05 ] . The difference in testosterone level was not significant between the control with infusion of physiological saline and herbal infusion group [(6.59 ±0.91), (6.98 ±0. 88) nmol/L, P ＞ 0.05].CONCLUSION: Under fatigue state, fian lifang can prolong the time of swimming in mice, improve work time and efficacy, increase hemoglobin content and benefit anti-hypoxia ability, which indicates rather strong anti-fatigue action. The combination of Chinese herbal jian lifang and exercise training can much' significantly increase serum testosterone level in rats compared with exercise group, which explains that fian li fang can increase testosterone level in rats, prevent testosterone decrease induced by exhausted exercise and accelerate the recovery of physical function.
