Zearalenone-induced Lymphophagocytosis (T Cell Apoptosis) on the Rat’s Thymus
Keywords: apoptosis, lymphophagocytosis, thymus, zearalenone
AbstractThe effects of nonsteroidal mycotoxin zearalenone on the lymphoid tissue of thymus in a sense of investigating the subacute toxicity Wistar-albino rats have been examined in the course of the study. We analyzed 42 rats' specimens of both gender, treated with three dosage levels: 0,5; 2 and 4 mg/kg of body weight, after oral submission of the compound, and observed during three different time intervals: 10, 20 and 30 days. Microscopically was semiquantitatively determined lymphophagocytosis (apoptosis) and cortical thymic cellularity. It was percepted statistically significant growth of lymphophagocytosis compared to a dosage (p<0,01), as well as combination of dosage and interval (p<0,001), while gender had no statistically significant influence on tested parameter (p>0,05). Changes in cortical thyme cellularity were not percepted. Effects of applied doses of zearalenone on the lymphoid tissue of thymus were very mild and in correlation with estrogenicity. They are probably the result of interaction with estrogenic receptors.
