Objective: The present study was undertaken to evaluate the immunomodulatory activity of the alcoholic extracts of Ruta graveolens leaves in vivo.
Methods: Immunomodulatory activity was determined by neutrophil adhesion test, phagocytic activity, haemagglutinating antibody (HA) titre and delayed-type hypersensitivity (DTH) response.
Results: Oral administration of the extracts (50, 100, 150 and 200 mg/kg bw, p. o) evoked a significant (**P<0.01) increased in percent of neutrophil adhesion to nylon fibers. Both the extracts were also increased the antibody titre in a dose-dependent manner. Oral administration of both the compound significantly (**P<0.01) potentiated delayed type hypersensitivity reaction induced by sheep red blood cells and response towards phagocytosis in carbon clearance assay. In this study indicated that leaves extracts possesses potent immune-modulatory activity in a concentration-dependent manner. The response was statistically significant when compared with the control (*P<0.05, **P<0.01).
Conclusion: The study stated that Ruta graveolens leaves extracts showed a significant stimulation of the cell-mediated immunity as well as humoral immunity. Further investigations are required to determine its active constituents and also its mechanism of action.
