Abstract:
Objective To study the effects of drug-containing serum of Ficus Hirta on oxidative damage of spleen lymphocyte due to aging in aged mice; To discuss its mechanism of action.Methods Forty aged mice were randomly divided into control group and high-, medium- and low-dose Ficus Hirta groups. Control group was given 0.9% sodium chloride solution for gavage, while high-, medium- and low-dose Ficus Hirta groups were given 6.6, 4.4, and 2.2 g/kg aqueous extract of Ficus Hirta for gavage. The spleen index was observed for optimum dose in aged mice. The optimum time and dilution of drug-containing serum of Ficus Hirta were confirmed by MTT method in lymphocyte proliferation test. The positive rate of senescent cells, the activity of T-SOD and the contents of MDA and ROS were determined in cellular antioxidant experiment after treated by optimal drug-containing serum for 48 h. Results Compared with the control group, the spleen index was significantly improved in high-, medium- and low-dose Ficus Hirta groups (P<0.05,P<0.01). 20% drug-containing serum of Ficus Hirta cultivated for 48 h had the best effects on lymphocyte proliferation in aged mice. 20% drug-containing serum of Ficus Hirta could significantly decrease the positive rate of senescent cells (P<0.01), improve T-SOD activity and decrease the contents of MDA and ROS (P<0.05,P<0.01).Conclusion The drug-containing serum of Ficus Hirta can improve the proliferative activity of spleen lymphocyte in aged mice and the mechanism of action may be involved in decreasing the positive rate of senescent cells and increasing antioxidant ability of lymphocyte.
