Abstract/OtherAbstract:
For evaluating the ability of selenium (Se) in counteracting the adverse effects of aflatoxin B1 (AFB1), two hundred 1-day-old male Avian broilers, divided into five groups, were fed with basal diet (control group), 0.3mg/kg AFB1 (AFB1 group), 0.3mg/kg AFB1+0.2mg/kg Se (+Se group I), 0.3mg/kg AFB1+0.4mg/kg Se (+Se group II) and 0.3mg/kg AFB1+0.6mg/kg Se (+Se group III), respectively. Compared with control group, the decreased relative weight of thymus and percentages of mature thymocytes, congestion in medulla and much debris in cortex of thymus, and the increased apoptotic thymocytes were observed in AFB1 group. However, supplied dietary sodium selenite could increase the relative weight of thymus and percentages of mature thymocytes, and alleviate histopathological lesions. Compared with AFB1 group, the percentages of apoptotic thymocytes detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method and flow cytometry method in three +Se groups were decreased, the expression of Caspase-3 and Bax, through quantitative real-time PCR and immunohistochemical method, in three +Se groups were decreased, while the expression of Bcl-2 was increased. The results indicate that sodium selenite supplied in the diet, through a mechanism of apoptosis regulation, may ameliorated AFB1-induced lesions of thymus and accordingly improve the impaired cellular immune function.
