茶色素改善记忆力的人体试验研究

目的]观察茶色素改善记忆力的作用。方法]采用双盲对照法,将105例受试者按记忆商高低排队,按奇、偶分两组,经检验两组记忆商均衡后,再随机分为试验组(53人)和对照组(52人),分别服用茶色素胶囊和安慰剂(淀粉)45天,测验受试者指向记忆、联想学习、图象自由回忆、无意义图形再认、人像特点联系回忆等5个量表分,计算记忆商。结果]两组试验后各分测量表分均高于试验前(P<0.01),而试验组指向记忆、无意义图形再认二项与对照组比较差异也有显著性(P<0.05),各分测量表分的升高差值与对照组比较,差异均有显著性(P<0.05);两组试验后记忆商均高于试验前(P<0.01),而试验组记忆商和升高差值与对照组比较差异均有显著性(P<0.01)。结论]茶色素具有改善记忆力的作用。

Test of Tea Pigment Improving Human Memory

Objective] To observe tea pigment's function on improving memory.Method] Take double-blind method,line the testees under memory quotients from high to low in odd and even groups;after balancing their memory quotients,randomly divide them into test group(53) and control group(52),respectively taking tea pigment capsule and placebo(starch) for 45 days,measuring their 5 scores of pointing memory,association study,image free memory,meaningless image recognition and image feature association memory for memory quotient.Result] After test,all scores were more than before test(P<0.01);there's marked difference between both groups on pointing memory and meaningless image recognition(P<0.05);the increased scores were different in both groups(P<0.01);so were the memory quotient and raised scores.Conclusion] Tea pigment can improve memory.
