The clinical study of 80 aged individuals divided into treated group (Group I) and normal control (Group II) was carried out. According to the symptoms of Kidney Deficiency the aged was subdivided into Kidney Deficiency group (KDG) and non-Kidney Deficiency group. A semi-quantitative method and some indexes about compliability were used to evaluate the symptoms. RESULTS After treatment the main symptoms of Kidney Deficiency such as lumbago, cold limbs, fatigue, cold aversion, feverish sensation in chest, palms and soles, etc. were significantly alleviated (P < 0.05) and the speed of reaction (SR) that reflects NS function in Group I and its KDG was also significantly improved. After exercise test, the ultrasono-cardiogram showed that in KDG of Group I, the ascending range of heart rate (HR) lessened during exercise and recovered more rapid than that before treatment. The difference was significant (P < 0.05). The HR was also significant different between the KDG groups of Group I and II during resting, exercise and recovering status (P < 0.05). Furthermore, after treatment the level of salival progesterone of the aged female was significantly. The determination of bone mineral content showed that in KDG after treatment, the density of ulnar line was remarkably elevated. These results showed that through tonifying Kidney and replenishing Qi could improve the functions of heart, brain, bone and endocrine systems of the aged persons, therefore improve their compliability.
