A yang-promoting Chinese herbal suppository preparation enhances the antioxidant status of red cells in male human subjects.
In the 16-week pilot study, the effect of a Yang-promoting Chinese herbal suppository preparation (VI-28) on the red cell antioxidant status was examined in 31 healthy male subjects aged 41-66 years old. VI-28 treatment for 12 weeks (one suppository (0.3 g) daily for week 1-4; one every 2 days for week 5-8; one every 3 days for week 9-12) produced a time/dose-dependent alteration in red cell antioxidant status. The VI-28-induced change is characterized by a slight depletion in cellular reduced glutathione (GSH) level and a decrease in susceptibility to peroxide-induced lipid peroxidation as well as increases in catalase (CAT) and Cu-Zn-superoxide dismutase (SOD) activities. While a reversal trend of change was observed in cellular GSH level, the susceptibility to lipid peroxidation as well as the CAT activity after the cessation of treatment for 4 weeks, the SOD activity exhibited a protracted increase. The results indicate that VI-28 treatment enhances red cell antioxidant status in male subjects. The beneficial effect of VI-28 treatment on red cells may re fl ect a corresponding change in antioxidant status of peripheral tissues.
