Study on immunomodulatory activity of root and rhizome of Rosa laevigata from different habitats / 中草药

ABSTRACT

Objective: To evaluate the immunomodulatory activity of the roots and rhizomes in Rosa laevigata (Rosa Laevigata Radix) in Guangxi, Yunnan, and Guizhou provinces. Methods: The effects of cellular immunity, humoral inmunity, and non-specific immunity were investigated on delayed-type hypersensitivity, serum hemolysin antibody, and carbon clearance of mice, respectively. Results: Rosa Laevigata Radix could inhibit the delayed-type hypersensitivity and serum hemolysin antibody in mice, but had no effect on carbon clearance. All the roots and rhizomes of R. laevigata from different habitats had no statistically significant difference on immunomodulatory activity. Conclusion: The roots and rhizomes of R. laevigata from different habitats have the similar immunosuppressive activity.
