Immunostimulating effects of sugar cane extract on X-ray radiation induced immunosuppression in the chicken.

The present study was undertaken to evaluate the effect of sugar cane (Saccharum officinarum L.) extract (SCE) on the immune system of X-ray immunosuppressed chickens. SCE (500 mg/kg/day) was administrated into the crop of 3-week-old chickens for three consecutive days before or after irradiation. The results indicated that administration of SCE before or after whole body X-ray irradiation enhanced both primary and secondary immune responses in chickens immunized with sheep red blood cells and Brucella abortus (BA) as well as cell-mediated immunity measured by delayed type hypersensitivity to human gamma-globulin.
