Abstract
ETHNOPHARMACOLOGICAL RELEVANCE
Radix Codonopsis and Radix Astragali, of which Shenqi Fuzheng Injection (SFI) is composed, are commonly used in traditional Chinese medicine to improve immune function against chronic diseases.
AIM OF THE STUDY
The present study was thus designed to systematically elucidate the in vivo immuno-enhancement effects of SFI in immunosuppressed mice induced by cyclophosphamide (Cy) treatment.
MATERIALS AND METHODS
Balb/c mice were injected intraperitoneally (i.p.) once daily with low-dose (2.5 g raw materials/kg), intermediate-dose (5 g raw materials/kg), high-dose (10 g raw materials/kg) of SFI for 10 consecutive days, respectively, accompanied by i.p. injection of Cy (80 mg/kg) on Days 4-6.
RESULTS
Compared with vehicle group, low-, intermediate- and high-dose SFI treatment accelerated recovery dose-dependently of spleen index, peripheral white blood cell and bone marrow cell counts, enhanced T cell and B cell proliferation responses, as well as splenic nature killer cell activity and peritoneal macrophage phagocytosis, and restored the level of interleukin-2 in the serum. Furthermore, SFI treatment promoted recovery of the amount of peripheral white blood cells on Day 6, rather than recombinant human Granulocyte Colony-Stimulating Factor (rhG-CSF) did.
CONCLUSIONS
These results demonstrate, for the first time, that chronic treatment with SFI results in accelerating recovery of immunosuppression in Cy-treated mice, which is competent in taking into consideration for both precautions and remedy. Our findings provide experimental evidences for further researches and clinical application in cancer patients undergoing chemotherapy.
