Objective: In order to search potent intervening means for low-level exercise-associated cellular immune capacities

effect of Radix Astragali injection and Aerobic exercise on quantities of peripheral T lymphocyte subsets in rats was observed. Method: 50 Wister Rats were randomLy divided into 5 group: quiet control group(n=10)

once exhausting exercise group(once exhausting exercise before drawning materials)(n=10)

Aerobic exercise and once exhausting exercise group(once exhausting exercise after aerobic exercise for four weeks)(n=10)

Radix Astragali injection and once exhausting exercise group(once exhausting exercise after oraling Radix Astragali injection for four weeks)(n=10)

Radix Astragali injection and Aerobic exercise and once exhausting exercise group(once exhausting exercise after oraling Radix Astragali injection and for aerobic exercise four weeks)(n=10). After 4 weeks test

time of exhaustive exercise were record

percentage of peripheral T Lymphocyte subsets in circulating blood were tested by FCM

and body weight were measured before and after experiment. Result: Afer exhausting exercise

percentage of CD4+ and the ratio of CD4+ to CD8+ in Lymphocyte subsets

as well as were lower(P<0.01)

percentage of CD8+ as well as were higher than that in normal control group(P<0.01).The change was prevented by Radix Astragali injection and aerobic exercise; the exhausting exercise time of aerobic exercise and once exhausting exercise group

astragali injection and once exhausting exercise group

Radix Astragali injection and aerobic exercise and once exhausting exercise group as well as were longer than once exhausting exercise group(P<0.01)

and the exhausting exercise time of Radix Astragali injection and aerobic exercise and once exhausting exercise group as well as were longer than aerobic exercise and once exhausting exercise group

Astragali injection and once exhausting exercise group(P<0.01). Conclusion: Radix Astragali injection and aerobic exercise may improve exercise capacity and preven immunosuppression in rats after exhaustive exercise in rats

enhance effect after combinating the two means.
