摘要
A test was carried out to evaluate. the effect of Qinggong Changchun capsule on de-creased fluid intelligence associated with aging. Nootropil and a placebo were used as the control drugs.Random, single-blind and self-control observation methods were applied. Ninety days were spent for clini-cal study. One hundred and fifty-four elderly subjects were divided into three groups (Test 63, nootropil60, placebo 31) . The method of measuring intelligence was gauged by communication between subject and computer. The measure included eight parameters. The main results were as follows: In the testgroup, there were significant differences (P<O. 01) in speed of calculation (5. 9±2. 5 s, 5. 1 ±12. 1 s) ,speed of digits and pictures (24. 2±6. 2 s, 21. 7±16. 7 s) , two-digit span (2. 8± 1. 0, 3. 2±0. 8) and an-other two parameters before and after treatment. In the nootropil group, some parameters were also im-proved significantly. But in the normal control there was not any evident change. The results suggest thatthe treatment is an effective therapy for decreased fluid intelligence with aging.
