Abstract

Objective: To explore the possible immuno-regulating mechanism of action of Chinese drugs in different combinations (assembled depending different therapeutic principles) through observing the effects of Feiliuping ointment (FLP) and its disassembled prescriptions on dendritic cells (DC) in blood, spleen and tumor in mice with transplanted Lewis lung cancer (LLC).

Methods: Percentages of DC in blood, spleen and tumor of mice with transplanted LLC treated by FLP and its disassembled prescriptions were estimated, and the S-100 protein expression in tumor tissue was detected by immunohistochemical method.

Results: The percentage of DC (per thousand) in tumor bearing mice was 0.43 +/- 0.26 in peripheral blood, and 0.32 +/- 0.16 in spleen, significantly lower than those in normal mice 4.68 +/- 0.90 and 3.68 +/- 1.58, P<0.01); and S-100 protein expression in tumor was weakened. After FLP treatment, the percentages of DC (per thousand) in tumor bearing mice were increased to 2.55 +/- 0.29 in peripheral blood and 2.70 +/- 0.63 in spleen (P<0.01), with the S-100 protein expression in tumor tissue up-regulated significantly (P<0.01). Study on different assembled prescriptions of FLP showed that the qi supplementing components of FLP displayed the optimal actions.

Conclusion: FLP, a Chinese herbal prescription made depending on Chinese medicine therapeutic principle of strengthening body resistance and consolidating constitution, has an obvious anti-tumor effect, to improve the immunological anti-tumor function of organism by promoting the amount and expression of DC might be the possible intrinsic mechanism.
