Clinical Study of the Effect of Wuzi Yanzong Solution for Retarding Senility

摘要

Eighty elderly men with symptoms of senility due to deficiency syndrome of the Kidney, but otherwise healthy, were randomly divided into two groups: one group was treated with Wuzi Yanzong Solution (WXYZS) and the other with a placebo, each for five weeks. After treatment, the symptoms of senility were ameliorated as judged by using a scoring method, the activity of the erythrocyte superoxide dismutase was increased, the plasma lipid peroxide content was reduced, the plasma testosterone level was raised and the plasma estradiol/testosterone ratio was decreased in the WZYZS group, while no changes were noticed in the placebo group. The results suggest that WZYZS retards senility in the aged, probably through its action of eliminating free radicals, reducing plasma lipid peroxide levels, elevating erythrocyte superoxide dismutase activity and regulating sex hormone levels.
