RESUMO
To investigate the effect of Astragali Radix with different sulfur fumigation technologies on immune function in mice, and observe the effect of different Astragali Radix samples on carbon clearance in cyclophosphamide induced immunosuppressed mice, on immune organ weight in immunosuppressed mice and on delayed type hypersensitivity response (DTH) induced by 2,4 dinitrochlorobenzene. Carbon clearance index, phagocytic index, organ index and ear swelling rate were taken as the indexes. The results showed that, all of the Astragali Radix with different sulfur fumigation technologies markedly increased the carbon clearance index K, phagocytic index α, immune organ weight and improved the ability of DTH response in immunosuppressed mice. As compared with the model group, combined hot air-microwave group had the most significant difference, but when other groups were compared with and combined hot air-microwave group, only carbon clearance test had significant difference. From the perspective of pharmacodynamics, the effect of Astragali Radix with different sulfur fumigationon technologies on the immune function of mice was investigated, which provided a reference for the selection of appropriate alternative technology, and also provided guidance for clinical medication.
