Zusammenfassung: | Introduction. Aflatoxins are metabolites produced by Aspergillus flavus and Aspergillus parasiticus. Due to the high prevalence of aflatoxin-containing products they are common issue of the observational studies. Observational studies have demonstrated the hepatotoxic effects of aflatoxins in humans. However, the exact pathogenetic mechanisms of the effect of aflatoxin B1 on the above-mentioned hepatotoxicity have not yet been known.
Aim of the study. The aim of the study was to assess the toxic effects of different doses of aflatoxin B1. The analyze was performed using assessment of concentration of NF-κB in liver tissue homogenates after a 7-day intoxication with this mycotoxin.
Material and methods. The studies were carried out on Wistar male rats which were selected randomly, according to the principle of simultaneity for the control group and the study groups. The concentration of NK-κB was determined by immunoenzymatic ELISA in the obtained supernatants of liver taken from decapitated animals. The statistical analysis was performed with Statistica 13.3 (Statsoft, USA).
Results. The statistical significance of the difference between the concentrations in the control and study group receiving 1.0 mg/kg of aflatoxin B1 and between the control and study group who received aflatoxin B1 at a dose of 2.0 mg/kg body weight (p |
