Objective: To explore the effect of total saponins of Ginseng leaves(GS) on the functions ofneutrophil and lymphocyte in the aged rats of 20 months. Methods: Three groups of aged rats were injected intraperiton-eally with doses of 12. 5 mg/kg, 25 kg/mg and 50 mg/kg of GS once daily for 3 days, the declinedimmunity of spleen lymphocytes (proliferation of spleen lymphocyte, phagocytosis), superoxide anion and nitricoxide formation were studied and were compared with those of young rats (2 months). Results: The declinedimmunity of spleen lymphocytes were improved dose-dependently after GS injected. Conclusion: The results indicate that GS may enhance neutrophil and lymphocyte mediated non--specific and specific defense function inaged rats.
