title: Immunomodulatory and antioxidant effect of Leptadenia reticulata leaf extract in rodents: possible modulation of cell and humoral immune response.
abstract: BACKGROUND
  Leptadenia reticulata Linn. (Asclpiadaceae) commonly known as "dodi," is an Indian medicinal plant which is known to have ethno-medical uses such as stimulant, tonic, immunostimulant and is one of the ingredient in ayurvedic formulation called as "Chawanprash," which is widely used in India to increase the strength of immune system.
  
  
  OBJECTIVE
  The aim of present study is to evaluate immunomodulatory and antioxidant activity of ethanolic extract of L. reticulata L. leaves in rodents.
  
  
  METHODS
  Haemagglutinating antibody (HA) titre, haematological profile (Hb, WBC, RBC), lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), delayed type of hypersensitivity (DTH) response, neutrophil adhesion test and carbon clearance assay were determined by in vivo experiments.
  
  
  RESULTS
  The evaluation of immunomodulatory potential of L. reticulata (100, 200 mg/kg, p.o.) evoked a significant dose-dependent increase in antibody titre values; DTH reaction induced by SRBC and potentiated percentage neutrophil adhesion to nylon fibers as well as phagocytosis in carbon clearance assay. Also it caused significant increase in haematological profile, GSH, SOD, CAT activity and significantly decreased LPO levels in cyclophosphamide-induced immunosuppressed rats.
  
  
  CONCLUSIONS
  The results obtained in this study indicate that L. reticulata possesses potential immunomodulatory and antioxidant activity and can play a major role in reducing the risk to develop immunodeficiency disorders.
