Opis:
The wide distribution of mycotoxins, including aflatoxin B1 and ochratoxin A, in the environment and their influence on living organisms make them an interesting research problem. Numerous complications of intoxication with these substances are known, however, particular attention is paid to the effects on the skeletal and nervous systems. The inflammatory effect, presented by the increase in the concentration of cytokines - IL-6 and TNF-α may influence the immune dysregulation present in bone metabolism disorders, as well as in neurodegeneration. Mycotoxins also contribute to osteodegeneration by modifying vitamin D metabolism. Interestingly, and still unexplored, is the mechanism of intrauterine influence on bone metabolism and neurodegeneration processes. Understanding the above mechanisms may help in monitoring the toxic effects of intoxication with these toxins. It can also help develop methods of therapy for poisoning with this compound, in animals and humans.

Opis:
During combine harvesting of 5 various cereal crops (rye, barley, oats, buckwheat, corn) 24 samples of grain and 24 samples of settled grain dust were collected on farms located in the Lublin province of eastern Poland. The samples were examined for the concentration of total microfungi, Fusarium species, deoxynivalenol (DON), nivalenol (NIV), and ochratoxin A (OTA). Microfungi able to grow on malt agar were present in 79.2% of grain samples and in 91.7% of grain dust samples in the concentrations of 1.0-801.3 × 103 cfu/g and 1.5-12440.0 × 103 cfu/g, respectively. The concentration of microfungi in grain dust samples was signifi cantly greater than in grain samples (p<0.01). Fusarium strains were isolated from 54.2% of grain samples and from 58.3% of grain dust samples in the concentrations of 0.1-375.0 × 103 cfu/g and 4.0-7,700.0 × 103 cfu/g, respectively. They were found in all samples of grain and grain dust from rye, barley and corn, but only in 0-16.7% of samples of grain and grain dust from oats and buckwheat. DON was found in 79.2% of grain samples and in 100% of grain dust samples in the concentrations of 0.001-0.18 μg/g and 0.006-0.283 μg/g, respectively. NIV was detected in 62.5% of grain samples and in 94.4% of grain dust samples in the concentrations of 0.004-0.502 μg/g and 0.005-0.339 μg/g, respectively. OTA was detected in 58.3% of grain samples and in 91.7% of grain dust samples in the concentrations of 0.00039- 0.00195 μg/g and 0.00036-0.00285 μg/g, respectively. The concentrations of DON, total fusariotoxins (DON + NIV) and OTA were signifi cantly greater in grain dust samples than in grain samples (p<0.05, p<0.05, and p<0.001, respectively). The concentration of Fusarium poae in the samples of rye grain and dust was signifi cantly correlated with the concentrations of DON (p<0.05), NIV (p<0.01), and total fusariotoxins (p<0.05). Similarly, the concentration of Fusarium culmorum in the samples of barley grain and dust was signifi cantly correlated with the concentration of total fusariotoxins (p<0.05). A signifi cant correlation was also found between the concentration of total fungi grown on malt agar and the concentration of OTA (p<0.05). In conclusion, although the concentration of DON, NIV and OTA in the samples of grain dust collected from 5 various cereals on farms in eastern Poland was not large, the persistent presence of these mycotoxins in over 90% of examined samples poses a potential health risk of chronic respiratory intoxication for exposed grain farmers.

Opis:
It is possible for humans and animals alike to be contaminated with mycotoxins such as ergot alkaloids, aflatoxins, ochratoxins and fusariotoxins. Aflatoxins are evaluated as strong carcinogens but their real occurrence and importance seems to be low in Europe. Ochra toxin A has become notorious mycotoxin especially in northern parts of Europe. Nephropathies are considered to be induced by ochratoxins. Immunosuppressive trichothecenes such as deoxynivalenol, T-2 toxin and the estrogenic zearalenone occur at high degrees in European cereals. Their roles in human diseases need further elucidation.
