刺五加茶饮料抗疲劳作用的实验研究

STUDY ON THE ANTIFATIGUE EFFECT OF TEA CONTAINING ACANTHOPANAX SENTICOSUS

目的 : 研究刺五加茶饮料对小鼠的抗疲劳作用。方法 : 48只昆明系小鼠平均分成 4组 ,其中刺五加茶饮料分 5 0 ,75 ,1 0 0 ml/(kg· d)三个剂量组给小鼠灌胃 ,对照组给等剂量生理盐水。共 2 8d,末次饲喂 3 0 min后无负重游泳 ,测定运动耐力、肌糖原、肝糖原、乳酸脱氢酶(LDH)、血乳酸 (LAC)、血尿素氮 (BUN)等指标。结果 : 三个剂量的刺五加茶饮料均能显著提高运动后 LDH活力 ;降低血 LAC和 BUN的含量 ;提高小鼠体内肌糖原和肝糖原的储备量 ;提高小鼠运动耐力。 75～ 1 0 0 ml/(kg· d)最佳。结论 : 刺五加茶饮料具有良好的抗疲劳作用。

Objective: To study the antifatigue effect of tea containing Acanthopanax senticosus.Methods: Forty eight mice were randomized into 4 groups:three groups of tea containing Acanthopanax senticosus at doses of 50, 75, 100 ml/(kg·d), and the saline group.After 4 w, muscle and liver glycogen, serum LDH activity, BUN and blood LAC were measured.Results: Three tea groups showed increase of muscle and liver glycogen,and serum LDH activity, and decrease of serum BUN and LAC in swimming mice.The 75-100 ml/(kg·d) group was the best.Conclusion: Tea containing Acanthopanax senticosus has antifatigue effect.
