Objective: To explore the change of serious abdominal traumatic patients’ cellular immunity and the effect of Astragalus Injection (AI) on it.Methods: Sixty-three serious abdominal traumatic patients were randomly assigned into two groups

the conventional group and the treated group

patients in the conventional group were given conventional treatment

while others in the treated group were given conventional treatment as the basis

with AI 20 ml was added into 250 ml of 5% glucose solution given through intravenous dripping

and then on the first day and 14th day

their T cell activated antigens as well as that of 10 healthy subjects were monitored.Results: On the first day

in the conventional group and treated group

the levels of CD 3 +

CD 4 +

CD 4 + /CD 8 +

CD 16 +

CD 69 + and CD 3 + /homologous leucocytic antigen-DR (HLA-DR+) were apparently lower than those in the healthy group (P<0.05)

while the CD 8 + was significantly higher than that in the healthy group (P<0.05)

and there was no significant difference between the conventional group and the treated group (P>0. 05); on the 14th days

the levels of CD 3 +

CD 4 +

CD 4 + /CD 8 +

CD 16 +

CD 69 + and CD 3 + /HLA-DR+ of the treated group got closed to healthy subject value

and got even higher than those of conventional group (P<0.05); CD 8 + got close to that of healthy subjects

while obviously lower than that of conventional group (P<0.05).Conclusion: After serious abdominal trauma

cellular immunity lowered

auxiliary use of AI was beneficial to the restoration of cellular immunity.
