Effetto del differente trattamento con raggi X sulla fase involutiva e di recupero del timo e della borsa di Fabrizio: analisi comparativa morfo-istologica in giovani pulcini (Gallus domesticus) di razza Wyandotte
A morpho-histologic study of the thymus and of the bursa Fabricii of young chicks (Wyandotte race) following experimental treatments was aim of the present research. The chicks were: 1) totally irradiated; 2) irradiated with shielded thymus; 3) irradiated with shielded bursa. A remarkable difference in X-ray-sensitivity and recovery between thymic and bursal lymphocytes was put into evidence. Moreover it was observed that thymus-shielding influences the percentage of picnotic lymphocytes in the...
